Recent astrophysical transient Swift J1913. 1+ 1946 is possibly associated with the gamma-
ray burst GRB 221009A at the redshift. The transient was accompanied by very high-energy …

The LHAASO Collaboration detected the gamma ray burst GRB 221009A at energies above
500 GeV with a tail extending up to 18 TeV, whose spectral analysis has presently been …

GRB 221009A was the brightest gamma-ray burst ever detected on Earth. In its early
afterglow phase, photons with exceptional energies above 10 TeV were observed by …

The detection of very high-energy neutrinos by IceCube experiment supports the existence
of a comparable gamma-ray counterpart from the same cosmic accelerators. Under the likely …

Context. GRB 221009A, initially detected as an X-ray transient by Swift, was later revealed to
have triggered the Fermi satellite about an hour earlier, marking it as a post-peak …

Axion-like particles (ALPs) are pseudo-Nambu–Goldstone bosons that emerge in various
theories beyond the standard model. These particles can interact with high-energy photons …

Dark matter could accumulate around neutron stars in sufficient amounts to affect their
global properties. In this work, we study the effect of a specific model for dark matter—a …

Axionlike particles (ALPs) are very light, neutral, spin zero bosons predicted by many
theories which try to extend and complete the standard model of elementary particles. ALPs …

Many extensions of the Standard Model of particle physics and in particular superstring and
superbrane theories predict the existence of axionlike particles (ALPs). ALPs are very …

Very high energy (VHE) photons may have a higher survival rate than that expected in
standard-model physics, as suggested by the recently reported gamma ray burst …
