The X/gamma-ray correlation in NGC 4945 and the nature of its gamma-ray source
(IOP Publishing for the American Astronomical Society, 2017)
We report hints for the correlation between the X-ray and gamma-ray emission in the nearby galaxy NGC 4945, which harbors both an active galactic nucleus and a nuclear starburst region. We have divided the Fermi/LAT ...
X-ray/γ-ray Correlation in Seyfert 2 Galaxy NGC 4945
(AIP Conference Proceedings - American Institute of Physics, 2017-01-04)
We report the correlation between the X-ray and γ-ray emission found in our analysis of the Fermi/LAT and Swift/BAT data from 8 years of observations of the nearby Seyfert 2 galaxy NGC 4945. Using the BAT light-curves we ...
Absorption effects in the blazar’s γ-ray spectra due to luminous stars crossing the jet
(Royal Astronomical Society, 2021)
γ-ray emission in active galaxies is likely produced within the inner jet, or in the close vicinity of the supermassive black hole (SMBH) at sub-parsec distances. γ-rays have to pass through the surrounding massive stellar ...
