  • 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 ...
  • Post-outburst Evolution of Bona Fide FU Ori-type V2493 Cygnus: A Spectro photometric Monitoring 
    Ghosh, Arpan; Sharma, Saurabh; Ninan, Joe P.; Ojha, Devendra K.; Bhatt, Bhuwan C.; Sahu, D. K.; Baug, Tapas; Yadav, R. K.; Irawati, Puji; Gour, A. S.; Panwar, Neelam; Pandey, Rakesh; Sinha, Tirthendu (The Astrophysical Journal, 2023-09)
    We present here the results of 8 yr of our near-simultaneous optical–near-infrared spectro-photometric monitoring of the bona fide FU Ori (FUor)-type candidate V2493 Cygnus (V2493 Cyg) starting from 2013 September to ...
  • PYTANSPEC: A data reduction package for TANSPEC 
    Ghosh, Supriyo; Ninan, Joe P.; Ojha, Devendra K.; Shrama, Saurabh (Journal Astrophysical Astronomy, 2023-06)
    TIFR-ARIES Near Infrared Spectrometer (TANSPEC) instrument provides simultaneous wave length coverage from 0.55 to 2.5 μm, mounted on India’s largest ground-based telescope, 3.6-m Devasthal Optical Telescope at Nainital, ...
  • 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 ...
