SAGAN -- III: New insights into giant radio quasars
Mousumi Mahato, Pratik Dabhade, D. J. Saikia +4
Giant radio quasars (GRQs) are radio-loud active galactic nuclei (AGNs), propelling megaparsec-scale jets. In order to understand GRQs and their properties, we have compiled all kn…
Changing look AGN Mrk 590: Broad line region and black hole mass from photometric reverberation mapping
Amit Kumar Mandal, Malte Schramm, Suvendu Rakshit +9
We present the results of photometric reverberation mapping observations on the changing look active galactic nucleus Mrk 590 at z = 0.026. The observations were carried out from J…
Presence of red giant population in the foreground stellar sub-structure of the Small Magellanic Cloud
Dizna James, Smitha Subramanian, Abinaya O. Omkumar +8
The eastern region of the Small Magellanic Cloud (SMC) is found to have a foreground stellar sub-structure, which is identified as a distance bimodality (12 kpc apart) in the previ…
Subaru Hyper Suprime-Cam Survey of Cygnus OB2 Complex -- I: Introduction, Photometry and Source Catalog
Saumya Gupta, Jessy Jose, Surhud More +11
Low mass star formation inside massive clusters is crucial to understand the effect of cluster environment on processes like circumstellar disk evolution, planet and brown dwarf fo…
Discovery of 2716 hot emission-line stars from LAMOST DR5
Shridharan B, Blesson Mathew, Nidhi S +4
We present a catalog of 3339 hot emission-line stars (ELS) identified from 451,695 O, B, and A type spectra, provided by the LAMOST DR5 release. We developed an automated python ro…
Identification of emission-line stars in transition phase from pre-main sequence to main sequence
Suman Bhattacharyya, Blesson Mathew, Gourav Banerjee +3
Pre-main sequence (PMS) stars evolve into main sequence (MS) phase over a period of time. Interestingly, we found a scarcity of studies in existing literature that examines and att…
