    Star formation primarily occurs in filaments where magnetic fields are expected to be dynamically important. The largest and densest filaments trace the spiral structure within galaxies. Over a dozen of these dense (∼104 ...

    Saha, Piyali; Archana Soam; Baug, Tapas; Maheswar, G; Mondal, Soumen; Ghosh, Tuhin (Oxford University Press on behalf of Royal Astronomical Society, 2022-06)
    The Lynds’ Dark Nebula (LDN) 1615/1616 and CB 28 (hereafter L1616) together form a cometary globule located at an angular distance of about 8◦ west of the Orion OB1 association, aligned roughly along the east–west direction, ...
  • The magnetic fields around the cometary globules L328, L323, and L331 
    Kumar, Siddharth; Archana Soam; Roy, Nirupam (Oxford University Press on behalf of Royal Astronomical Society, 2023-09)
    This work presents the magnetic field geometry in a complex of three cometary (with head–tail morphology) globules, namely LDN 323, LDN 328, and LDN 331, using R-band polarization measurements of background stars. These ...
  • On the Scarcity of Dense Cores (n>105 cm−3 ) in High-latitude Planck Galactic Cold Clumps

Viktor (American Astronomical Society, 2024-03-01)
    High-latitude (|b| > 30°) molecular clouds have virial parameters that exceed 1, but whether these clouds can form stars has not been studied systematically. Using JCMT SCUBA-2 archival data, we surveyed 70 fields that ...
  • The Origin of Dust Polarization in the Orion Bar 
    Gouellec, Valentin J. M. Le; Andersson, B-G; Archana Soam; Schirmer, Thiébaut; Michail, Joseph M.; Lopez-Rodriguez, Enrique; Flores, Sophia; Chuss, David T.; Vaillancourt, John E.; Hoang, Thiem; Lazarian, Alex (American Astronomical Society, 2023-07-10)
    The linear polarization of thermal dust emission provides a powerful tool to probe interstellar and circumstellar magnetic fields, because aspherical grains tend to align themselves with magnetic field lines. While the ...
  • Physics and Chemistry of Radiation Driven Cloud Evolution. [C II] Kinematics of IC 59, and IC 63 
    Caputo, Miranda; Archana Soam; Andersson, B-G; Dennis, Remy; Chambers, Ed; Gusten, Rolf; Knee, Lewis B. G; Stutzki, Jurgen (American Astronomical Society, 2023-06-20)
    We used high-resolution [C II] 158 μm mapping of two nebulae IC 59 and IC 63 from SOFIA/upGREAT in conjunction with ancillary data of the gas, dust, and polarization to probe the kinematics, structure, and magnetic properties ...
  • The role of magnetic fields in the stability and fragmentation of filamentary molecular clouds: two case studies at OMC-3 and OMC-4 
    Li, Pak Shing; Lopez-Rodriguez, Enrique; Archana Soam; Klein, Richard I (Oxford University Press on behalf of Royal Astronomical Society, 2022-08)
    We present the stability analysis of two regions, OMC-3 and OMC-4, in the massive and long molecular cloud complex of Orion A. We obtained 214 μm HAWC + /SOFIA polarization data, and we make use of archival data for the ...
  • SOFIA Observations of 30 Doradus. II. Magnetic Fields and Large-scale Gas Kinematics

    The heart of the Large Magellanic Cloud, 30 Doradus, is a complex region with a clear core-halo structure. Feedback from the stellar cluster R136 has been shown to be the main source of energy creating multiple parsecscale ...
