Constraining the TeV gamma-ray emission of SN 2024bch, a possible type IIn-L from a red supergiant progenitor. Multiwavelength observations and analysis of the progenitor

The CTAO-LST Project, :, K. Abe +332

We present very high-energy optical photometry and spectroscopic observations of SN 2024bch in the nearby galaxy NGC 3206 (\sim 20 Mpc). We used gamma-ray observations performed wi…

Search for Spatial Correlations of Neutrinos with Ultra-High-Energy Cosmic Rays

The ANTARES collaboration, A. Albert, S. Alves +1042

For several decades, the origin of ultra-high-energy cosmic rays (UHECRs) has been an unsolved question of high-energy astrophysics. One approach for solving this puzzle is to corr…

Modelling the propagation of very-high-energy gamma rays with the CRbeam code: Comparison with CRPropa and ELMAG codes

O. Kalashev, A. Korochkin, A. Neronov +1

Very-high-energy gamma rays produce electron positron pairs in interactions with low-energy photons of extragalactic background light during propagation through the intergalactic m…

The UHECR dipole and quadrupole in the latest data from the original Auger and TA surface detectors

Peter Tinyakov, Luis Anchordoqui, Teresa Bister +13

The sources of ultra-high-energy cosmic rays are still unknown, but assuming standard physics, they are expected to lie within a few hundred megaparsecs from us. Indeed, over cosmo…

UHECR arrival directions in the latest data from the original Auger and TA surface detectors and nearby galaxies

Armando di Matteo, Luis Anchordoqui, Teresa Bister +13

The distribution of ultra-high-energy cosmic-ray arrival directions appears to be nearly isotropic except for a dipole moment of order per cent. None…

Dark matter component decaying after recombination: constraints from diffuse gamma-ray and neutrino flux measurements

Oleg E. Kalashev, Mikhail Yu. Kuznetsov, Yana V. Zhezher

We consider scenario of the dark matter consisting of two fractions, stable part being dominant and a smaller unstable fraction, which has decayed after the recombination epoch. It…
