Polarimetric and photometric investigation of a dark globule LDN 1225: distance, extinction law, and magnetic fields
Chakali Eswaraiah, Shih-Ping Lai, Yuehui Ma +7
We present the results based on the optical -band polarization observations of 280 stars distributed towards the dark globule LDN\,1225. {\it Gaia} data release 2 parallaxes alo…
Investigating inner and large scale physical environments of IRAS 17008-4040 and IRAS 17009-4042 toward l = 345.5 deg, b = 0.3 deg
Lokesh K. Dewangan, Tapas Baug, Devendra K. Ojha +1
We present a multi-wavelength observational study of IRAS 17008-4040 and IRAS 17009-4042 to probe the star-formation (SF) mechanisms operational in both the sites. Each IRAS site i…
The study of a system of H II regions toward l = 24.8 deg, b = 0.1 deg at the Galactic bar - Norma arm interface
L. K. Dewangan, J. S. Dhanya, D. K. Ojha +1
To probe the star formation (SF) process, we present a thorough multi-wavelength investigation of several H II regions located toward l = 24.8 deg, b = 0.1 deg. A system of at leas…
The Planck Cold Clump G108.37-01.06: A Site of Complex Interplay between H II Regions, Young Clusters and Filaments
Somnath Dutta, Soumen Mondal, Manash R Samal +1
The {\it Planck} Galactic Cold Clumps (PGCCs) are the possible representations of the initial conditions and the very early stages of star formation. With an objective to understan…
Near-Infrared Spectroscopy of SN 2017eaw in 2017: Carbon Monoxide and Dust Formation in a Type II-P Supernova
J. Rho, T. R. Geballe, D. P. K. Banerjee +3
The origin of dust in the early Universe has been the subject of considerable debate. Core-collapse supernovae (ccSNe), which occur several million years after their massive progen…
Filamentary Structures and Star Formation Activities in the Sites S234, V582, and IRAS 05231+3512
L. K. Dewangan, T. Baug, D. K. Ojha +2
To investigate the physical processes, we present observational results of the sites S234, V582, and IRAS 05231+3512 situated toward l = 171.7 - 174.1 degrees. Based on the CO line…
Investigating kpc-scale radio emission properties of narrow-line Seyfert 1 galaxies
Veeresh Singh, Hum Chand
In recent years, several Radio-Loud Narrow-Line Seyfert 1 galaxies (RL-NLS1) possessing relativistic jets have come into attention with their detections in Very Large Baseline Arra…
Cloud-Cloud Collision Induced Star Formation in IRAS 18223-1243
L. K. Dewangan, D. K. Ojha, I. Zinchenko +1
In the direction of l = 17.6 - 19 deg, the star-forming sites Sh 2-53 and IRAS 18223-1243 are prominently observed, and seem to be physically detached from each other. Sh 2-53 has…
Optical variability in IBL S5 0716+714 during the 2013-2015 outburst
Navpreet Kaur, Kiran S. Baliyan, S. Chandra +2
With an aim to explore optical variability at diverse timescales in BL Lac source S5 0716+714, it was observed for 46 nights during 2013 January 14 to 2015 June 01 when it underwen…
CTA 102 in exceptionally high state during 2016-17
Navpreet Kaur, Kiran S Baliyan
Blazars outburst provide an opportunity to study their spectral behaviour, correlated variations, and structure of the jet. Such an unprecedented flaring activity in FSRQ CTA102, d…
The embedded ring-like feature and star formation activities in G35.673-00.847
L. K. Dewangan, R. Devaraj, D. K. Ojha
We present a multi-wavelength study to probe the star formation (SF) process in the molecular cloud linked with the G35.673-00.847 site (hereafter MCG35.6), which is traced in a ve…
Deuterated Formaldehyde in the low mass protostar HH212
Dipen Sahu, Young-Chol Minh, Chin-Fei Lee +4
HH212, a nearby (400 pc) object in Orion, is a Class 0 protostellar system with a Keplerian disk and collimated bipolar SiO jets. Deuterated water, HDO and a deuterated complex mol…
