Soft contribution to the damping rate of a hard photon in a weakly magnetized hot medium
Ritesh Ghosh, Bithika Karmakar, Munshi G Mustafa
We consider weakly magnetized hot QED plasma comprising electrons and positrons. There are three distinct dispersive (longitudinal and two transverse) modes of a photon in a thermo…
Investigating the origin of the Fe emission lines of the Seyfert 1 galaxy Mrk~205
Sibasish Laha, Ritesh Ghosh, Shruti Tripathi +1
We have investigated the nature and origin of the Fe K emission lines in Mrk~205 using observations with {\it Suzaku} and {\it XMM-Newton}, aiming to resolve the ambiguity between…
Anisotropic pressure of deconfined QCD matter in presence of strong magnetic field within one-loop approximation
Bithika Karmakar, Ritesh Ghosh, Aritra Bandyopadhyay +2
Considering the general structure of the two point functions of quarks and gluons, we compute the free energy and pressure of a strongly magnetized hot and dense QCD matter created…
