Investigating star formation activity in the Sh 2-61 H II region
Rakesh Pandey, Saurabh Sharma, Lokesh Dewangan +4
Using the multiwavelength data sets, we studied the star formation activity in H II region Sh 2-61 (hereafter S61). We identified a clustering in the region and estimated the membe…
Investigating kinematics and dynamics of three open clusters towards Galactic anti-center
Geeta Rangwal, R. K. S. Yadav, D. Bisht +2
We present the intra-cluster kinematics and dynamics of three open clusters: NGC 1193, NGC 2355, and King 12 by incorporating kinematical and photometric data from Gaia DR3, as wel…
Kronberger 55: A Candidate for End-dominated Collapse Scenario
Aayushi Verma, Saurabh Sharma, Lokesh Dewangan +5
Using optical photometric observations from 1.3m Devasthal Fast Optical Telescope and deep near-infrared (NIR) photometric observations from TANSPEC mounted on 3.6m Devasthal Optic…
A deep investigation of two poorly studied open clusters Haffner 22 and Melotte 71 in Gaia era
D. Bisht, Quingfeng Zhu, R. K. S. Yadav +4
This paper presents a deep investigation of two open clusters, Haffner 22 and Melotte 71, using astrometric and photometric data from Gaia EDR3. We identified 382 and 597 most prob…
Intranight variability of UV emission from powerful blazars
Krishan Chand, Gopal-Krishna, Amitesh Omar +4
We report the first study to characterise intranight variability of the blazar class from the perspective of (rest-frame) UV emission. For this, we carried out intranight optical m…
Optical Flux and Colour Variability of Blazars in the ZTF Survey
Vibhore Negi, Ravi Joshi, Krishan Chand +4
We investigate the temporal and colour variability of 897 blazars, comprising 455 BL Lacertae objects (BL Lacs) and 442 Flat Spectrum Radio Quasars (FSRQs), selected from the Roma-…
