22 Newly Identified Repeating Changing-look AGNs and Evidence for Extreme Broad-line Region Breathing
Litao Zhu, Zhongxiang Wang, Alok C. Gupta +5
Changing-look active galactic nuclei (CL AGNs) show the appearance or disappearance of broad emission lines on timescales of years. Among them, the repeating CL (RCL) AGNs may prov…
X-ray Spectral Properties of Four Classical TeV Blazars using Simultaneous Observations from NICER and NuSTAR
Riya Bhowmick, Alok C. Gupta
We present a detailed study of X-ray spectral properties observed in 4 classical TeV (tera-electron volt) photon-emitting high synchrotron-peaked BL Lacertae objects using the simu…
Accretion Flow Properties of EXO 1846-031 During its Multi-Peaked Outburst After Long Quiescence
Sujoy Kumar Nath, Dipak Debnath, Kaushik Chatterjee +3
We study the recent outburst of the black hole candidate EXO 1846-031 which went into an outburst in 2019 after almost 34 years in quiescence. We use archival data from Swift/XRT,…
Properties of MAXI J1348-630 during Its Second Outburst in 2019
Riya Bhowmick, Dipak Debnath, Kaushik Chatterjee +2
The newly discovered galactic black hole candidate (BHC) MAXI~J1348-630 showed two major outbursts in 2019, just after its discovery. Here, we provide a detailed spectral and tempo…
Properties of 2017-18 'failed' Outburst of GX 339-4
Dipak Debnath, Kaushik Chatterjee, Sujoy Kumar Nath +2
The Galactic transient black hole candidate GX 339-4 is a very interesting object to study as it showed both complete and failed types of outbursts. We studied both spectral and te…
Accretion Flow Properties of MAXI J1910-057/Swift J1910.2-0546 During Its 2012-13 Outburst
Sujoy Kumar Nath, Dipak Debnath, Kaushik Chatterjee +3
Galactic black hole candidate MAXI J1910-057/Swift J1910.2-0546 was simultaneously discovered by MAXI/GSC and Swift/BAT satellites during its first outburst in 2012. We study the d…
