A study of shear viscosity coefficient of quark matter in Polyakov quark meson model for three flavors
Ritesh Ghosh
We have computed shear viscosity coefficient for hot and dense QCD matter within Polyakov loop extended quark meson(PQM) model for three flavors. Viscosity coefficient is estimated…
A weakening Compton hump and soft X-ray excess detected in the Seyfert-1 galaxy MCG-02-58-22
Sibasish Laha, Ritesh Ghosh
We have carried out an extensive X-ray spectral study of the bare Seyfert-1 galaxy MCG--02--58--22 to ascertain the nature of the X-ray reprocessing media, using observations from…
Anisotropic pressure and quark number susceptibility of strongly magnetized QCD medium
Bithika Karmakar, Ritesh Ghosh, Aritra Bandyopadhyay +2
In this work, we compute the hard thermal loop pressure of quark-gluon plasma within strong magnetic field approximation at one-loop order. Magnetic field breaks the rotational sym…
Chiral susceptibility in dense thermo-magnetic QCD medium within HTL approximation
Ritesh Ghosh, Bithika Karmakar, Munshi Golam Mustafa
We have computed the chiral susceptibility in quark-gluon plasma in presence of finite chemical potential and weak magnetic field within hard thermal loop approximation. First we c…
Short-Timescale Variability of the Blazar Mrk 421 from AstroSat and Simultaneous Multi-Wavelength Observations
Ritaban Chatterjee, Susmita Das, Archishman Khasnovis +13
We study the multi-wavelength variability of the blazar Mrk 421 at minutes to days timescales using simultaneous data at -rays from Fermi, 0.7-20 keV energies from AstroSat, and…
