The Gravitational Wave (GW) events GW150914, GW151226, GW170104 detected by LIGO were a record of Black Hole binary merging system (BH-BH) very probably in nearly empty or a vacuum space; such a kind of events will be mostly with no baryon mass (plasma or dense masses) and therefore mute or blind in any correlated gamma band. If the GWs events might be born inside a globular cluster, a star forming region or along a spiral AGN accretion disk their additional accreting mass may be the needed baryon load to explode and shine: in those dense places. BH BH collapse may also offer an optical X and gamma afterglow via their baryon lightening and photon tracks. Only very nearby (tens Mpc) BH Neutron Star (NS) or NS NS cannibal merging might be guaranteed and associated also with a desired, visible and correlated spherical NS explosion (kilonova one); they require much lower threshold or just nearer distances. Indeed such a very exceptional GW170817 GRB170817a event occurred last August 2017; it took place and it was related to a very first NS NS collapse in a SN kilonova spherical explosion. The GRB170817a gamma, X, radio signature it was exceptional in many features . Its unique values (softer, weaker, the most near and long life one) made GRB170817a very possibly an off-axis jet detection. However there are solid arguments that suggest that such a GRB are not just blazing within a collimated beam jet but that they are also shining in a wider spread gamma equatorial disk blazing, orthogonal to the jet itself. In a few words we were observing the event not along its jet but mostly orthogonal to it. This GRB170817a geometry may better explain the otherwise unexpected beamed to us event. In this paper therefore we summarize the astrophysical and the cosmological signature of such a long desired multiple astronomy.

Recently (May-July 2013) highest energy neutrino events have been presented by ICECUBE. Most (21) of all these (28) events are cascades shower whose flux exhibits a sharp hardening respect other lower energy atmospheric neutrino component; these events are suggesting an injection of extraterrestrial neutrino, mostly of electron or tau flavor, making cascades. ICECUBE claimed that a component (10-12) of these events must be a trace of expected downward muons and-or atmospheric neutrinos (mostly muon track dominated): this imply that nearly all of the few observed muon tracks (at least 6 of the 7) must be themselves of atmospheric origin: therefore remaining 16-18 extraterrestrial events must be mostly of electron or of tau flavor (or rare neutral current events). The probability that this scenario occurs is very poor, about 0.1-0.5%, well below 1.0%. This muon neutrino paucity paradox cannot be solved if part or even all the events are made by terrestrial prompt charmed signals. The paradox might be somehow solved if nearly all of the 28 events are originated by extraterrestrial sources arriving to us in de-coherent states. This overestimation of atmospheric neutrino flux has deep consequences. Few cascades shower events in Antares yearly might test the flavor changes at TeVs and tens TeV energy range.

Every GRB model where the progenitor is assumed to be a highly relativistic hadronic jet whose pions, muons and electron pair secondaries are feeding the gamma jets engine, necessarily (except for very fine-tuned cases) leads to a high average neutrino over photon radiant exposure (radiance), a ratio well above unity, though the present observed average IceCube neutrino radiance is at most comparable to the gamma in the GRB one. Therefore no hadronic GRB, fireball or hadronic thin precessing jet, escaping exploding star in tunneled or penetrarting beam, can fit the actual observations. A new model is shown here, based on a purely electronic progenitor jet, fed by neutrons (and relics) stripped from a neutron star (NS) by tidal forces of a black hole or NS companion, showering into a gamma jet. Such thin precessing spinning jets explain unsolved puzzles such as the existence of the X-ray precursor in many GRBs. The present pure electron jet model, disentangling gamma and (absent) neu...

IceCube Neutrino Astronomy is considered. The tau neutrino flavor paucity and the asymmetry for the tracks suggest a dominant atmospheric charm noise. The correlated cascades and tracks asymmetry with relevant statistics enforce the charm noise dominance in the data. The charm signal may explain at once the absence of correlation for the tracks data with the galactic plane and with known brightest gamma sources.

Since 2013 IceCube cascade showers sudden overabundance have shown a fast flavor change above 30-60 TeV up to PeV energy. This flavor change from dominant muon tracks at TeVs to shower events at higher energies, has been indebted to a new injection of a neutrino astronomy. However the recent published 54 neutrino HESE, high energy starting events, as well as the 38 external muon tracks made by trough going muon formed around the IceCube, none of them are pointing to any expected X-gamma or radio sources: no one in connection to GRB, no toward active BL Lac, neither to AGN source in Fermi catalog. No clear correlation with nearby mass distribution (Local Group), nor to galactic plane. Moreover there have not been any record (among a dozen of 200 TeV energetic events) of the expected double bang due to the tau neutrino birth and decay. An amazing and surprising unfair distribution in flavor versus expected democratic one. Finally there is not a complete consistence of the internal HES...

High Energy Neutrino Astronomy has been revealed by a sudden change in the flavor composition around maximal energies since three years of recording in ice km detector. However these discover didn' t led to any clear promised Neutrino Astronomy land yet. No correlation with hard gamma sources was found. Moreover the astrophysical spectra expected at Fermi value, seem to converge to a softer value, also required to avoid any Glashow resonant neutrino signal. We suggest a main solution within a composite flux ruled by prompt atmospheric neutrinos. Nevertheless the recent discover of twentyone crossing muons at hundreds TeVs had shown a first narrow overlapped doublet and a correlated track with a peculiar hard UHECR event clustering pointing to a well known microjet in bynary precession; these first connections hint for a non negligible astrophysical component making neutrino astronomy anyway already more than a hope.

We argue that any GRB model where the progenitor is made by high relativistic hadronic interactions shock waves, and later on by electron-pairs feeding gamma jets, is necessarily leading to an average high neutrino over photon fluency ratio well above unity, mostly above several thousands. The present observed average highest energy ICECUBE neutrino energy fluency is at most comparable to the gamma-X in GRB one. Therefore no hadronic GRB, Fireball or even any earliest hadronic thin precessing Jet, may fit the observation. We therefore imagine a novel electronic thin spinning and precessing jet, born in late binary system where a NS stripped by tidal forces feed an accreating ring around BH or NS companion, able to avoid the overcrowded neutrino tails foreseen in hadronic GRB models. In some occasion such an electronic model may lead to an explosion, due to stripped NS unstability, that shines during a GRB with an (apparent) late SN-like event.

The largest Solar flare have been recorded in gamma flash and hard spectra up to tens GeV energy. The present building and upgrade of Hyper-Kamiokande (HK) and IceCube (as well as Deep Core, PINGU) neutrino detectors do offer a novel way to largest trace of solar Flare: their sudden anti-neutrino (or neutrino) flare made by proton scattering and pion decays via Delta resonance production. These signals might be observable at largest flare by HK via soft spectra up to tens- hundred MeV energy and by IceCube-PINGU at higher, GeV up to hundred GeV, energies. We show the expected rate of signals for the most powerful solar flare occurred in recent decades.

The Moon may become soon a novel filtering calorimeter and an amplifier of energetic muon neutrinos (at TeV up to hundred TeV energy), lepton track decaying to Earth. Also a more energetic PeV up to EeV tau neutrino events may be escaping from the Moon to us shining in a surprising way. One or a few gamma air-shower event inside the Moon shadows may occur each year in near future CTA or LHAASO TeVs gamma array detector, assuming a non negligible astrophysical TeV up to hundred TeV neutrino component (respect to our ruling atmospheric ones); these signals will open a new wonderful passepartout keyhole for neutrino been seen along the Moon. The lunar solid angle is small and the muon or tau expected rate is rare, but even future largest tau radio array as the GIANT one, might reach this new neutrino signals offering a novel and a spectacular view of the highest energy neutrino sky.

Gamma jets (G J) at MeV energies may be produced in galactic halos by Inverse Compton Scattering (ICS) of coUinear ultrarelativistic electron beams (at GeV energies) onto thermal photons. These electron jets are emitted by neutron star jets (NSJ) or black holes (BH) while the target thermal photons are generated by a nearby binary stellar- like companion (or by a relic accreting disk). The GJ precesses in a conical shape as a lighthouse (with a characteristic Keplerian binary period) forced by the NSJ magnetic lines interaction with the stellar companion ones. The sudden blazing of the G J, once the observer is into the beam cone direction, is detected as a GRB. Our predicted GRB spectra fit the GRB observed ones; GRB luminosity, variabihty and counts are well explained if the GJ sources are located in an "extended" and an "evaporating" galactic halo as the one recently required in the fast running away NS model. Observed jets such as SS433, the Great Annihilator...

The exciting development of gravitational wave (GW) astronomy in the correlation of LIGO and VIRGO detection of GW signals makes possible to expect registration of effects of not only binary black hole (BH) coalescence but also binary neutron star (NS) merging accompanied by electromagnetic (gamma ray burst; GRB) signal. Here we consider the possibility that an NS, merging in an NS–NS or NS–BH system might be (soon) observed in correlation with any LIGO–VIRGO GWs detection. We analyze as an example the recent case of the short GRB170817A observed by Fermi and integral. The associated optical transient (OT) source in NGC4993 implies a rare near source, a consequent averaged large rate of such events (almost) compatible with expected NS–NS merging rate. However the expected beamed GRB (or short GRB) may be mostly aligned to a different direction than ours. Therefore, even soft GRB photons, spread more than hard ones, might be hardly able to shower to us. Nevertheless, a prompt spirali...

The Sun albedo of Cosmic Rays (CRs) at GeVs energy has been discovered recently by the FERMI satellite. They are traces of atmospheric CRs hitting solar atmosphere and reflecting skimming gamma photons. Even if relevant for astrophysics, as being a trace of atmospheric solar CR noises they cannot offer any signal of neutrino astronomy. On the contrary, the Moon with no atmosphere, may become soon a novel filtering calorimeter and an amplifier of energetic muon astronomical neutrinos (at TeV up to hundred TeVs energy); these lepton tracks leave an imprint in their beta decay while in flight to Earth. Their TeV electron air-shower are among the main signals. Also, a more energetic, but more rare, PeV up to EeV tau lunar neutrino events may be escaping as a tau lepton from the Moon: [Formula: see text] PeV secondaries, then, may be shining on Earth’s atmosphere in lunar shadows in a surprising way. One or a few gamma air-shower events inside the Moon shadows may occur each year in near...

We discuss recent results on the clustering, composition and distribution of Ultra-High Energy Cosmic Rays (UHECR) in the sky; from the energy of several tens of EeV in the dipole anisotropy, up to the highest energy of a few narrow clusters, those of Hot Spots. Following the early UHECR composition records deviations from proton we noted that the UHECR events above 40 EeV can be made not just by any light or heavy nuclei, but mainly by the lightest ones as He,D, Li,Be. The remarkable Virgo absence and the few localized nearby extragalactic sources, such as CenA, NGC 253 and M82, are naturally understood: lightest UHECR nuclei cannot reach us from the Virgo distance of twenty Mpc, due to their nuclei fragility above a few Mpc distances. Their deflection and smearing in wide hot spots is better tuned to the lighter nuclei than to the preferred proton or heavy nuclei candidate courier. We note that these lightest nuclei still suffer of a partial photodistruction even from such close s...

The most distant AGN, within the allowed GZK cut-off radius, have been recently candidate by many authors as the best location for observed UHECR origination. Indeed, the apparent homogeneity and isotropy of recent UHECR signals seems to require a far cosmic isotropic and homogeneous scenario involving a proton UHECR courier: our galaxy or nearest local group or super galactic plane (ruled by Virgo cluster) are too much near and apparently too much anisotropic in disagreement with PAO and TA almost homogeneous sample data. However, the few and mild observed UHECR clustering, the North and South Hot Spots, are smeared in wide solid angles. Their consequent random walk flight from most far GZK UHECR sources, nearly at 100 Mpc, must be delayed (with respect to a straight AGN photon gamma flaring arrival trajectory) at least by a million years. During this time, the AGN jet blazing signal, its probable axis deflection (such as the helical jet in Mrk501), its miss alignment or even its a...

The CoVid-19 is spreading pandemically all over the world. A rapid defeat of the pandemic requires carrying out on the population a mass screening, able to separate positive from negative cases. Such a cleaning will free a flow of productive population. The current rate and cost of testing, performed with the common PCR (polymerase chain reaction) method and with the available resources, is forcing a selection of the subjects to be tested. Indeed, each one must be examined individually at the cost of precious time. Moreover, the exclusion of potentially positive individuals from screening induces health risks, a broad slowdown in the effort to curb the viral spread, and the consequent mortality rates. We present a new procedure, the Purified by Unified Resampling of Infected Multitudes, in short Purim, able to untangle any massive candidate sample with inexpensive screening, through the cross-correlated analysis of the joint speciments. This procedure can reveal and detect most nega...

The Gravitational Wave (GW) event GW150914 detected by LIGO was very probably a record of a vacuum Black Hole merging system (BH-BH); such kind of events will be mostly mute in gamma region and unobservable or, by best triangulation, widely smeared because of the absence of any spherically-symmetric electromagnetic pointing trace. If the GW150914 event is born inside a globular cluster, a star forming region or along an AGN accretion disk, it might offer optical-X-gamma afterglow via baryon tracks, whom might trace as well their boosted Kepler and Lorentz viscous imprint inside the very same GWs structure, also via peculiar Shapiro phase delay. On the contrary the very rare thin beamed BH jets, related to relic accretion disk around these merging BHs, might shine and blaze most probably not toward us. Only very nearby (tens Mpc) BH-Neutron Star (NS) or NS-NS cannibal merging might be associated to spherical NS explosion and they might therefore be localized by photon tracks in a nea...
