Search for decaying eV-mass axion-like particles using gamma-ray signal from blazars
A. Korochkin, A. Neronov, D. Semikoz
Decaying axion-like particles (ALP) with masses in the eV range which might occupy dark matter halos of the Milky Way and other galaxies produce a characteristic "bump" feature in…

Search for spectral features in extragalactic background light with gamma-ray telescopes
A. Korochkin, A. Neronov, D. Semikoz
Cumulative optical and infrared emission from galaxies accumulated over cosmological time scales, the extragalactic background light (EBL), could be probed by complementary techniq…

Search for anomalous features in gamma-ray blazar spectra corrected for the absorption on the extragalactic background light
Alexander Korochkin, Grigory Rubtsov, Sergey Troitsky
We consider the ensemble of very-high-energy gamma-ray sources observed at distances and energies where a significant absorption of gamma rays is expected due to pair production on…
