What is the highest energy at which gravitons can be observed? We address this question
by studying graviton-to-photon conversion—the inverse-Gertsenshtein effect—in the …

The newly observed gamma ray burst GRB221009A exhibits the existence of 10 TeV-scale
photons, and the axion-photon conversion has been suggested as a candidate to explain …

Photon–axion-like particle (ALP) oscillations result in the survival of gamma rays from distant
sources above TeV energies. Studies of events observed by CAST, Fermi-LAT, and IACT …

Axion-like particles (ALPs) are new particles that extend beyond the standard model (SM)
and are extensively investigated. When considering ALPs within an effective field theory …

We present the limits on photon to axionlike particle (ALP) coupling from the 10-year period
observations of the TeV BL Lacertae blazar 1ES 1215+ 303 (with redshift z= 0.130). The …

We investigate the photon-axionlike particle (ALP) oscillation effects on TeV gamma-ray
spectral irregularities from the uncertain redshift active galactic nuclei (AGN) VER J 0521+ …

At the beginning of 2020, MAGIC reported a very-high-energy (VHE) flaring activity from the
FSRQ QSO B 1420+ 326. It is now the fourth known most distant blazar (z= 0.682) with an …

In the beyond Standard Model (BSM) scenarios, the possibility of neutrinos decaying into a
lighter state is one of the prime quests for the new-generation neutrino experiments. The …

Wave or fuzzy dark matter that is produced with relativistic wavenumbers exhibits free
streaming effects analogous to warm or hot particle dark matter with relativistic momenta …

In this paper, we explore the phenomenology of massive Axion-Like Particles (ALPs)
coupled to quarks and gluons, dubbed'QCD ALPs', with an emphasis on the associated low …
