Star formation and evolution of blister-type H{\sc ii} region Sh2-112
Neelam Panwar, Saurabh Sharma, D. K. Ojha +4
We report the observational findings of the Sh2-112 H{\sc ii} region by using the multiwavelength data analysis ranging from optical to radio wavelengths. This region is powered by…
New insights in the HII region G18.88-0.49: hub-filament system and accreting filaments
L. K. Dewangan, D. K. Ojha, Saurabh Sharma +3
We present an analysis of multi-wavelength observations of an area of 0.27 deg x 0.27 deg around the Galactic HII region G18.88-0.49, which is powered by an O-type star (age ~10^5…
Star-forming sites IC 446 and IC 447: an outcome of end-dominated collapse of Monoceros R1 filament
N. K. Bhadari, L. K. Dewangan, L. E. Pirogov +1
We present an analysis of multi-wavelength observations of Monoceros R1 (Mon R1) complex (at d ~760 pc). An elongated filament (length ~14 pc, mass ~1465 Msun) is investigated in t…
Probing the physical conditions and star formation processes in the Galactic HII region S305
L. K. Dewangan, Saurabh Sharma, Rakesh Pandey +5
We present multi-scale and multi-wavelength observations of the Galactic HII region S305, which is excited by massive O8.5V and O9.5V stars. Infrared images reveal an extended sphe…
Uncovering distinct environments in an extended physical system around the W33 complex
L. K. Dewangan, T. Baug, D. K. Ojha
We present a multi-wavelength investigation of a large-scale physical system containing the W33 complex. The extended system (~50 pc x 37 pc) is selected based on the distribution…
Investigating the physical conditions in extended system hosting mid-infrared bubble N14
L. K. Dewangan, T. Baug, L. E. Pirogov +1
To observationally explore physical processes, we present a multi-wavelength study of a wide-scale environment toward l = 13.7 - 14.9 degrees containing a mid-infrared bubble N14.…
Unveiling the physical conditions in NGC 6910
Harmeen Kaur, Saurabh Sharma, Lokesh K. Dewangan +3
Deep and wide-field optical photometric observations along with multiwavelength archival datasets have been employed to study the physical properties of the cluster NGC 6910. The s…
Stellar cores in the Sh 2-305 H II region
Rakesh Pandey, Saurabh Sharma, Neelam Panwar +6
Using our deep optical and near-infrared photometry along with multiwavelength archival data, we here present a detailed study of the Galactic H II region Sh 2-305, to understand t…
