Magnetic field-dependent electric charge transport in hadronic medium at finite temperature
Ritesh Ghosh, Manu Kurian
Electric charge transport of hadronic matter at finite temperature and magnetic field is studied within the linear sigma model. Anisotropic transport coefficients associated with t…
The origin of the vanishing soft X-ray excess in the changing-look Active Galactic Nucleus Mrk 590
Ritesh Ghosh, Sibasish Laha, Kunal Deshmukh +3
We have studied the nature and origin of the soft X-ray excess detected in the interesting changing-look AGN (CLAGN) Mrk~590 using two decades of multi-wavelength observations from…
Collective modes of gluons in an anisotropic thermo-magnetic medium
Bithika Karmakar, Ritesh Ghosh, Arghya Mukherjee
We study the collective modes of gluons in an anisotropic thermal medium in the presence of a constant background magnetic field using the hard-thermal loop (HTL) perturbation theo…
Heavy quark potential and LQCD based quark condensate at finite magnetic field
Indrani Nilima, Aritra Bandyopadhyay, Ritesh Ghosh +1
In the present work, we have studied heavy quarkonia potential in hot and magnetized quark gluon plasma. Inverse magnetic catalysis (IMC) effect is incorporated within the system t…
Anisotropic tomography of heavy quark dissociation by using general propagator structure at finite magnetic field
Ritesh Ghosh, Aritra Bandyopadhyay, Indrani Nilima +1
In this work we have explored the imaginary part of the Heavy Quark (HQ) potential and subsequently the dissociation of heavy quarkonia at finite temperature and magnetic field. Wi…
Shear Viscosity of hadronic matter at finite temperature and magnetic field
Ritesh Ghosh, Najmul Haque
We calculate the transport coefficient of hadronic matter in the presence of temperature and magnetic field using the linear sigma model. In the relaxation time approximation, we e…
Limits on the hard X-ray emission from the periodic fast radio burst FRB 180916.J0158+65
Sibasish Laha, Zorawar Wadiasingh, Tyler Parsotan +11
FRB 180916.J0158+65 is one of the nearest, periodically repeating, and actively bursting fast radio burst (FRB) which has been localized to the outskirts of a spiral galaxy. In thi…
Simultaneous view of the FRB~180301 with FAST and NICER during a bursting phase
Sibasish Laha, George Younes, Zorawar Wadiasingh +16
FRB180301 is one of the most actively repeating fast radio bursts (FRBs) which has shown polarization angle changes in its radio burst emission, an indication for their likely orig…
A radio, optical, UV and X-ray view of the enigmatic changing look Active Galactic Nucleus 1ES~1927+654 from its pre- to post-flare states
Sibasish Laha, Eileen Meyer, Agniva Roychowdhury +17
The nearby type-II AGN 1ES1927+654 went through a violent changing-look (CL) event beginning December 2017 during which the optical and UV fluxes increased by four magnitudes over…
