Investigation of Hourglass-shaped Magnetic fields in the G35.20-0.74 Star-Forming Complex
O. R. Jadhav, L. K. Dewangan, A. K. Maity +7
To investigate the role of magnetic fields toward the G35N and G35S sub-regions in the G35.20-0.74 star-forming complex, we utilized multi-wavelength polarimetric observations from…
Unveiling an Hourglass-Shaped Magnetic Field toward IRDC G351.77-0.53
O. R. Jadhav, L. K. Dewangan, I. I. Zinchenko +5
We present the SOFIA/HAWC+ 214 m polarimetric observations toward the infrared dark cloud G351.77-0.53 (hereafter G351), complemented by existing multi-wavelength data sets. In…
Black hole-Neutron star distinction based on long-term MAXI and Swift study of 42 low mass X-ray binaries
Prakhar Maheshwari, Mayukh Pahari, Anish Sarkar +1
In this study, we analysed about 13 years of publicly available data from MAXI and Swift/BAT to examine the long-term source evolution of 42 transient low-mass X-ray binaries…
Discovery of a rich population of compact hub-filament systems in a single star-forming complex
L. K. Dewangan, Ram K. Yadav, Saurabh Sharma +4
We report the discovery of 45 compact hub-filament systems (HFSs; median size 2.4 pc) in infrared-dark clouds (IRDCs) in the W33 complex, located at the junction of the Scutu…
Are Kronberger 80 and/or Kronberger 82 regions PeVatron candidates for LHAASO J2108+5157?
Akash Gupta, Eduardo De La Fuente, Ram K. Yadav +13
High-energy gamma rays have been detected in the region of LHAASO~J2108+5157 by the Fermi--LAT, HAWC and LHAASO-KM2A observatories. Cygnus~OB2 in Cygnus--X has been confirmed as th…
Investigating Embedded Structures and Gas Kinematics in the IRDC Hosting Bubble N59-North
A. K. Maity, L. K. Dewangan, O. R. Jadhav +5
We present a multi-wavelength study of an extended area hosting the bubble N59-North to explore the physical processes driving massive star formation (MSF). The Spitzer 8 m ima…
