  • Exploring Stellar Cluster and Feedback-driven Star Formation in the Galactic Mid infrared Bubble [HKS2019] E70 
    Verma, Aayushi; Sharma, Saurabh; Mallick, Kshitiz K.; Dewangan, Lokesh; Ojha, Devendra K.; Yadav, Ram Kesh; Pandey, Rakesh; Ghosh, Arpan; Kaur, Harmeen; Panwar, Neelam; Chand, Tarak (The Astrophysical Journal, 2023-08)
    We present a comprehensive analysis of the Galactic mid-infrared bubble [HKS2019] E70 (E70) by adopting a multiwavelength approach to understand the physical environment and star formation scenario around it. We identified ...
  • Kronberger 55: A candidate for end-dominated collapse scenario 
    Verma, Aayushi; Shrama, Saurabh, et.al; Ghosh, Arpan (Journal Astrophysical Astronomy, 2023-06)
    Using optical photometric observations from 1.3-m Devasthal Fast Optical Telescope and deep near infrared (NIR) photometric observations from TANSPEC mounted on 3.6-m Devasthal Optical Telescope, along with the multi-wavelength ...
  • New Insights in the Bubble Wall of NGC 3324: Intertwined Substructures and a Bipolar Morphology Uncovered by JWST 
    Dewangan, L. K.; Maity, A. K.; Mayya, Y. D.; Bhadari, N. K.; Bhattacharyya, Suman; Sharma, Saurabh; Banerjee, Gourav (The Astrophysical Journal, 2023-11)
    We report the discovery of intertwined/entangled substructures toward the bubble wall of NGC 3324 below a physical scale of 4500 au, which is the sharp edge/ionization front/elongated structure traced at the interface between ...
  • Structure and Kinematics of Sh2-138—A Distant Hub-filament System in the Outer Galactic Plane 
    Mallick, Kshitiz K.; Dewangan, Lokesh K.; Ojha, Devendra K.; Baug, Tapas; Zinchenko, Igor I. (The Astrophysical Journal, 2023-02)
    We present a molecular line study of the Sh2-138 (IRAS 22308+5812) hub-filament system with the aim of investigating its structure and kinematics. Archival CO molecular line data from the Canadian Galactic Plane Survey ...
