We have remotely mapped optical scattering and absorption in glacial ice at the South Pole for wavelengths between 313 560 nm depths 1100 2350 m. used pulsed continuous light sources embedded with AMANDA neutrino telescope, an array of more than six hundred photomultiplier tubes buried deep ice. At greater 1300 m, both coefficient absorptivity follow vertical variations concentration dust impurities, which are seen cores from other Antarctic sites track climatological changes. The varies by...
The exploration of the universe has recently entered a new era thanks to multi-messenger paradigm, characterized by continuous increase in quantity and quality experimental data that is obtained detection various cosmic messengers (photons, neutrinos, rays gravitational waves) from numerous origins. They give us information about their sources properties intergalactic medium. Moreover, astronomy opens up possibility search for phenomenological signatures quantum gravity. On one hand, most...
High-energy cosmic rays are observed indirectly by detecting the extensive air showers initiated in Earth's atmosphere. The interpretation of these observations relies on accurate models shower physics, which is a challenge and an opportunity to test QCD under extreme conditions. Air hadronic cascades, eventually decay into muons. muon number key observable infer mass composition rays. simulations with state-of-the-art show significant deficit respect measurements; this called Muon Puzzle....
We report the observation of a steepening in cosmic ray energy spectrum heavy primary particles at about 8×10(16) eV. This structure is also seen all-particle spectrum, but less significant. Whereas "knee" 3-5×10(15) eV was assigned to light masses by KASCADE experiment, new found KASCADE-Grande experiment caused primaries. The result obtained independent measurements charged particle and muon components secondary extensive air showers range 10(16) 10(18) data are analyzed on single-event...
The dependence of collective nuclear flow on multiplicity and beam energy for Ca+Ca, Nb+Nb, Au+Au collisions has been measured with the Plastic Ball detector at Bevalac. Event by event data are analyzed transverse-momentum method a new quantitative measure effect is extracted. It expected that comparison present systematic results model calculations will lead to more precise determination nuclear-matter equation state.
We present the simulation framework CRPropa version 3 designed for efficient development of astrophysical predictions ultra-high energy particles. Users can assemble modules most relevant propagation effects in galactic and extragalactic space, include their own physics with new features, receive on output primary secondary cosmic messengers including nuclei, neutrinos photons. In extension to contained a previous version, facilitates high-performance computing comprises physical features...
Recent results of the KASCADE-Grande experiment provided evidence for a mild knee-like structure in all-particle spectrum cosmic rays at $E={10}^{16.92\ifmmode\pm\else\textpm\fi{}0.10}\text{ }\text{ }\mathrm{eV}$, which was found to be due steepening flux heavy primary particles. The combined components light and intermediate masses compatible with single power law energy range from ${10}^{16.3}$ ${10}^{18}\text{ }\mathrm{eV}$. In this paper, we present an update analysis by using data...
Abstract The landscape of high- and ultra-high-energy astrophysics has changed in the last decade, largely due to inflow data collected by large-scale cosmic-ray, gamma-ray, neutrino observatories. At dawn multimessenger era, interpretation these observations within a consistent framework is important elucidate open questions this field.

A measurement of direct photon production in ${}^{208}\mathrm{Pb}{+}^{208}\mathrm{Pb}$ collisions at $158A$ GeV has been carried out the CERN WA98 experiment. The invariant yield photons central is extracted as a function transverse momentum interval $0.5<{p}_{T}<4\mathrm{GeV}/c$. significant signal, compared to statistical and systematical errors, seen ${p}_{T}>1.5\mathrm{GeV}/c$. result constitutes first observation ultrarelativistic heavy-ion collisions. It could be for diagnosis...
The flow of light nuclei ($Z=1, 2$) and intermediate-mass nuclear fragments ($3\ensuremath{\le}Z<10$) is measured in collisions 200-MeV/nucleon Au+Au over a large solid angle. An increase the fragment-position momentum-space alignment relative to reaction plane observed: exhibit stronger effects than particles.
Squeeze-out, a component of the collective flow nuclear matter, is preferential emission particles out reaction plane. Using sphericity method out-of-plane/in-plane ratio kinetic energy has been analyzed as function multiplicity and beam for Ca+Ca, Nb+Nb, Au+Au collisions measured with Plastic Ball detector at Bevalac. Also, azimuthal distribution around axis are presented together extracted ratios. Finally, rapidity dependence investigated new using transverse momentum components particles.
Correlations between intermediate-mass fragments (IMF's) and heavy were measured for $^{18}\mathrm{O}$-induced reactions on $^{\mathrm{nat}}\mathrm{Ag}$ $^{197}\mathrm{Au}$ at $\frac{E}{A}=84$ MeV. of two coincident IMF's show a depletion small relative velocities ${v}_{\mathrm{rel}}\ensuremath{\le}1$ cm/ns, reflecting the proximity point creation. However, time scales IMF emission derived from this correlation are similar to those binary-IMF-heavy-recoil coincidences which indicates...
To understand the feedback of black holes on their environment or acceleration ultra-high energy cosmic rays in present epoch, a systematic, all-sky inventory radio galaxies local universe is needed. Here we first catalog radio-emitting that meets this requirement. Our allows selection volume-limited subsamples containing all low-power galaxies, similar to prototypical Cen A M87, within some hundred Mpc. It constructed by matching emission from NVSS and SUMSS surveys 2MASS Redshift Survey...
