Some Seyfert galaxies are detected in high-energy gamma rays, but the mechanism and site
of gamma-ray emission are unknown. Also, the origins of the cosmic high-energy neutrino …

Sgr A* exhibits regular variability in its multiwavelength emission, including daily X-ray flares
and roughly continuous near-infrared (NIR) flickering. The origin of this variability is still …

Accurate fitting formulae to the synchrotron function, F (x), and its complementary function, G
(x), are performed and presented. The corresponding relative errors are less than 0.26 …

In several high-energy astrophysical sites, shocks are assumed to produce a power-law
distribution of accelerated charged particles (eg, electrons, protons) and to generate mild to …

We have derived asymptotic forms for the degree of polarization of the optically thin
synchrotron and for synchrotron self-absorption (SSA) spectra assuming a power-law …

Widespread use of a broken-power-law description of the spectra of synchrotron emission of
various plasma objects requires an analysis of origin and a proper interpretation of spectral …

We have analysed a sample of 328 time-integrated GRB prompt emission spectra taken via
the Konus instrument on board the US GGS-Wind spacecraft between 2002 and 2004 using …

Synchrotron emission behind relativistic magnetic internal‐external shocks in gamma‐ray
bursts cosmological explosions is assumed to be the basic emission mechanism for prompt …

We have calculated the inverse Compton (IC) integrated spectral power within the Thomson
limit for a monoenergetic isotropic photon field upscattered off highly relativistic electrons …
