The Non-Uniform Expansion of the Crab Nebula
T. Martin, D. Milisavljevic, T. Temim +4
We present extensive proper motion measurements of the Crab Nebula made from Canada-France-Hawaii Telescope MegaPrime/MegaCam images taken in 2007, 2016, and 2019. A total of 19974…
Probing properties of nearly two-hundred new active galactic nuclei
Samrat Ghosh, Samir Mandal, Sudip Bhattacharyya +1
We present a comprehensive analysis of the X-ray spectral properties of 198 newly identified active galactic nuclei (AGNs), leveraging archival data from the {\it Chandra} X-ray Ob…
AT2020ohl: its nature and probable implications
Rupak Roy, Samir Mandal, D. K. Sahu +3
ASASSN-20hx, a.k.a AT2020ohl, is an ambiguous nuclear transient (ANT), which was discovered in the nearby galaxy NGC6297 by the All-Sky Automated Survey for Supernovae (ASAS-SN). W…
Spectral Properties of M87 Using Two-Component Flow
Samir Mandal
We fit the observational data for M87 using two-component advective disk model. We show that the flat spectrum from the nucleus of M87 is due to synchrotron radiation produced by n…
