An X-ray spectral study of the origin of reflection features in bare Seyfert 1 galaxy ESO 511--G030
Ritesh Ghosh, Sibasish Laha
The reprocessed X-ray emission from Active Galactic Nuclei (AGN) is an important diagnostic tool to study the dynamics and geometry of the matter surrounding the supermassive black…
Covariant formulation of gluon self-energy in presence of ellipsoidal anisotropy
Ritesh Ghosh, Bithika Karmakar, Arghya Mukherjee
In this work, a covariant formulation of the gluon self-energy in presence of ellipsoidal anisotropy is considered. It is shown that the general structure of the gluon self-energy…
A broadband X-ray spectral study of the Seyfert 1 galaxy ESO 141--G055 with XMM-Newton and NuSTAR
Ritesh Ghosh, Sibasish Laha
We have extensively studied the broadband X-ray spectra of the source ESO~141--G055 using all available \xmm{} and \nustar{} observations. We detect a prominent soft excess below 2…
Dynamics of QCD Matter -- current status
Amaresh Jaiswal, Najmul Haque, Aman Abhishek +58
In this article, there are 18 sections discussing various current topics in the field of relativistic heavy-ion collisions and related phenomena, which will serve as a snapshot of…
Blazar Variability: A Study of Non-stationarity and the Flux-RMS Relation
Joy Bhattacharyya, Ritesh Ghosh, Ritaban Chatterjee +1
We analyze X-ray light curves of the blazars Mrk 421, PKS 2155-304, and 3C 273 using observations by the Soft X-ray Telescope on board AstroSat and archival XMM-Newton data. We use…
