Low-power jet-ISM coupling and disk-plane perturbations in the edge-on Seyfert galaxy NGC 4388
M. Ceci, G. Venturi, C. Marconcini +26
Active galactic nuclei (AGN) may regulate galaxy evolution through radiatively driven winds and collimated jets, but their relative impact and coupling to the interstellar medium (…
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…
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…
Quasar Feedback Survey: molecular gas affected by central outflows and by ~10 kpc radio lobes reveal dual feedback effects in `radio quiet' quasars
A. Girdhar, C. M. Harrison, V. Mainieri +17
We present a study of molecular gas, traced via CO (3-2) from ALMA data, of four z< 0.2, `radio quiet', type 2 quasars (log [L(bol)/(erg/s)] = 45.3 - 46.2; log [L(1.4 GHz)/(W/Hz)]…
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…
Asymmetric accretion and thermal `mountains' in magnetized neutron star crusts
Neha Singh, Brynmor Haskell, Dipanjan Mukherjee +1
Accreting neutron stars are one of the main targets for continuous gravitational wave searches, as asymmetric accretion may lead to quadrupolar deformations, or `mountains', on the…
Millihertz quasi-periodic oscillations and broad iron line from LMC X-1
Md. Shah Alam, G. C. Dewangan, T. Belloni +2
We study the temporal and energy spectral characteristics of the persistent black hole X-ray binary LMC X-1 using two XMM-Newton and a Suzaku observation. We report the discovery o…
