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…
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…
A comparative study of radio signatures from winds and jets: Modelling synchrotron emission and polarization
Moun Meenakshi, Dipanjan Mukherjee, Gianluigi Bodo +2
Outflows driven by active galactic nuclei (AGN) are seen in numerous compact sources; however, it has remained unclear how to distinguish between the driving mechanisms, such as wi…
A polarization study of jets interacting with turbulent magnetic fields
Moun Meenakshi, Dipanjan Mukherjee, Gianluigi Bodo +1
We investigate the effect of the jet's immediate surroundings on the non-thermal synchrotron emission and its polarization properties. The ambient medium is equipped with a turbule…
Morphology of radio relics I: What causes the substructure of synchrotron emission?
P. Domínguez-Fernández, M. Brüggen, F. Vazza +5
High-resolution radio observations of cluster radio relics often show complex spatial and spectral features. However, it is not clear what these features reveal about the underlyin…
