Non-thermal emission in jets and winds: Expected emission and spectral index distributions
M. Meenakshi, D. Mukherjee, G. Bodo +5
The origin of synchrotron emission in compact radio sources associated with active galactic nuclei (AGN) remains poorly understood. In a series of papers, we have examined diagnost…
Enhanced UV emission knot in the giant radio galaxy NGC 315: Hint of patchy star formation?
Bannanje Ananthamoorthy, Debbijoy Bhattacharya, Dipanjan Mukherjee +1
High-resolution AstroSat-UltraViolet Imaging Telescope (UVIT) observations revealed a knot of UV emission, kpc away from the centre of NGC 315, a nearby elliptical galax…
Investigating field burial by magnetically confined accretion mounds on Neutron Stars
Saurabh Yeole, Dipanjan Mukherjee, Ankush Mandal
We explore the problem of magnetic confinement of accreted matter forming an accretion mound near the magnetic poles of a neutron star. We calculate the magnetic field geometry of…
Discovery of a new phase-transient cyclotron line in A0535+26: Constraints on the accretion geometry
Ashwin Devaraj, Biswajit Paul, Varun Bhalerao +1
In November 2020, A0535+26 underwent one of its brightest outbursts, reaching nearly 12 Crab in X-ray flux. Observed by \textit{Insight-HXMT}, \textit{NuSTAR}, \textit{NICER}, and…
