Star formation in the Sh 2-53 region influenced by accreting molecular filaments
T. Baug, L. K. Dewangan, D. K. Ojha +6
We present a multi-wavelength analysis of a 3030 area around the Sh 2-53 region (hereafter S53 complex), which is associated with at least three H II regions, tw…
Interstellar extinction in twenty open star clusters
Geeta Rangwal, R. K. S. Yadav, Alok Durgapal +1
The interstellar extinction law in twenty open star clusters namely Berkeley 7, Collinder 69, Hogg 10, NGC 2362, Czernik 43, NGC 6530, NGC 6871, Bochum 10, Haffner 18, IC 4996, NGC…
New insights in the mid-infrared bubble N49 site: a clue of collision of filamentary molecular clouds
L. K. Dewangan, D. K. Ojha, I. Zinchenko
We investigate the star formation processes operating in a mid-infrared bubble N49 site, which harbors an O-type star in its interior, an ultracompact HII region, and a 6.7 GHz met…
Observational signatures of cloud-cloud collision in the extended star-forming region S235
L. K. Dewangan, D. K. Ojha
We present a multi-wavelength data analysis of the extended star-forming region S235 (hereafter E-S235), where two molecular clouds are present. In E-S235, using the 12CO (1-0) and…
High Spectral Resolution SOFIA/EXES Observations of C2H2 towards Orion-IRc2
Naseem Rangwala, Sean W. J. Colgan, Romane Le Gal +8
We present high-spectral resolution observations from 12.96 - 13.33 microns towards Orion IRc2 using the mid-infrared spectrograph, EXES, on SOFIA. These observations probe the phy…
Embedded filaments in IRAS 05463+2652: early stage of fragmentation and star formation activities
L. K. Dewangan, R. Devaraj, T. Baug +1
We present a multi-wavelength data analysis of IRAS 05463+2652 (hereafter I05463+2652) to study star formation mechanisms. A shell-like structure around I05463+2652 is evident in t…
The molecular cloud S242: physical environment and star formation activities
L. K. Dewangan, T. Baug, D. K. Ojha +3
We present a multi-wavelength study to probe the star formation (SF) processes on a larger scale (~1.05 deg x 0.56 deg) around the S242 site. The S242 molecular cloud is depicted i…
On the nature of infrared-faint radio sources in the SXDF and VLA-VVDS fields
Veeresh Singh, Yogesh Wadadekar, C. H. Ishwara-Chandra +4
Infrared-Faint Radio Sources (IFRSs) are an unusual class of objects that are relatively bright at radio wavelengths but have faint or undetected infrared counterparts even in deep…
Multi-wavelength study of flaring activity in HBL 1ES 1959+650 during 2015-16
Navpreet Kaur, S. Chandra, Kiran S Baliyan +2
We present the results from a multiwavelength study of the flaring activity in HBL, 1ES 1959+650, during January 2015-June 2016. The source underwent significant flux enhancements…
Hub-filament system in IRAS 05480+2545: young stellar cluster and 6.7 GHz methanol maser
Lokesh K. Dewangan, Devendra K. Ojha, Tapas Baug
To probe the star formation (SF) process, we present a multi-wavelength study of IRAS 05480+2545 (hereafter I05480+2545). Analysis of Herschel data reveals a massive clump (M_clump…
Optical intra-day variability in 3C 66A: 10 years of observations
Navpreet Kaur, Sameer, Kiran S. Baliyan +1
We present results based on the observations of the blazar 3C 66A from 2005 November 06 to 2016 February 14 in the BVR and I broadbands using 1.2m telescope of the Mt. Abu InfraRed…
The Possibility of Forming Propargyl Alcohol in the Interstellar Medium
Prasanta Gorai, Ankan Das, Liton Majumdar +3
Propargyl alcohol (HC2CH2OH, PA) has yet to be observed in the interstellar medium (ISM) although one of its stable isomers, propenal (CH2CHCHO), has already been detected in Sagit…
