Physical insights from the spectrum of the radio halo in MACS J0717.5+3745
K. Rajpurohit, G. Brunetti, A. Bonafede +18
We present new LOFAR observations of the massive merging galaxy cluster MACS J0717.5+3745. The cluster hosts the most powerful radio halo known to date. These new observations, in…
The Relativistic Jet Orientation and Host Galaxy of the Peculiar Blazar PKS 1413+135
A. C. S. Readhead, V. Ravi, I. Liodakis +26
PKS 1413+135 is one of the most peculiar blazars known. Its strange properties led to the hypothesis almost four decades ago that it is gravitationally lensed by a mass concentrati…
Understanding the radio relic emission in the galaxy cluster MACS J0717.5+3745: spectral analysis
K. Rajpurohit, D. Wittor, R. J. van Weeren +21
Radio relics are diffuse, extended synchrotron sources that originate from shock fronts generated during cluster mergers. The massive merging galaxy cluster MACS J0717.5+3745 hosts…
uGMRT detection of associated HI 21 cm absorption at
J. N. H. S. Aditya, Regina Jorgenson, Vishal Joshi +3
We report a uGMRT detection of HI 21-cm absorption associated with the radio source 8C 0604+728, at . The source is at the highest redshift at which associated HI 21-c…
Testing the star formation scaling relations in the clumps of the North American and Pelican cloud complexes
Swagat R. Das, Jessy Jose, Manash R Samal +2
The processes which regulate the star-formation within molecular clouds are still not well understood. Various star-formation scaling relations have been proposed to explain this i…
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…
CHIMPS2: Survey description and CO emission in the Galactic Centre
D. J. Eden, T. J. T. Moore, M. J. Currie +103
The latest generation of Galactic-plane surveys is enhancing our ability to study the effects of galactic environment upon the process of star formation. We present the first data…
The First Mid-Infrared Detection of HNC in the Interstellar Medium: Probing the Extreme Environment Towards the Orion Hot Core
Sarah Nickerson, Naseem Rangwala, Sean Colgan +7
We present the first mid-infrared (MIR) detections of HNC and H13CN in the interstellar medium, and numerous, resolved HCN rovibrational transitions. Our observations span 12.8 to…
The PDR structure and kinematics around the compact HII regions S235A and S235C with [CII], [13CII], [OI] and HCO+ line profiles
M. S. Kirsanova, V. Ossenkopf-Okada, L. D. Anderson +11
The aim of the present work is to study structure and gas kinematics in the photodissociation regions (PDRs) around the compact HII regions S235A and S235C. We observe the [CII], […
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…
A Systematic Study on the Absorption Features of Interstellar Ices in Presence of Impurities
Prasanta Gorai, Milan Sil, Ankan Das +12
Spectroscopic studies play a key role in the identification and analysis of interstellar ices and their structure. Some molecules have been identified within the interstellar ices…
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.…
