The first look at Narrow-Line Seyfert 1 Galaxies with eROSITA
G. Grünwald, Th. Boller, S. Rakshit +6
We present the first look at the spectral and timing analysis of Narrow-Line Seyfert 1 Galaxies (NLS1s) with the extended ROentgen Survey with an Imaging Telescope Array (eROSITA)…
Spectroscopic reverberation mapping of Quasar PKS 0736+017: Broad-Line Region and Black-hole Mass
Shivangi Pandey, Suvendu Rakshit, Jong-Hak Woo +1
To understand the mass distribution and co-evolution of supermassive black holes with their host galaxy, it is crucial to measure the black hole mass of AGN. Reverberation mapping…
On the origin of core radio emissions from black hole sources in the realm of relativistic shocked accretion flow
Santabrata Das, Anuj Nandi, C. S. Stalin +5
We study the relativistic, inviscid, advective accretion flow around the black holes and investigate a key feature of the accretion flow, namely the shock waves. We observe that th…
Flux and spectral variability of Mrk 421 during its moderate activity state using NuSTAR: Possible accretion disc contribution?
Santanu Mondal, Priyanka Rani, C. S. Stalin +2
The X-ray emission in BL Lac objects is believed to be dominated by synchrotron emission from their relativistic jets. However, when the jet emission is not strong, one could expec…
Host galaxy properties of quasi-periodically erupting X-ray sources
T. Wevers, D. R. Pasham, P. Jalan +2
Quasi-periodic X-ray eruptions (QPEs) are a recently discovered phenomenon, the nature of which remains unclear. Based on their discovery in active galactic nuclei (AGN), explanati…
