Gas Kinematics and Dynamics of Carina Pillars: A Case Study of G287.76-0.87

Tung, Ngo-Duy; Tram, Le Ngoc; Archana Soam; Reach, William T; Das, Edwin; Chambers, Ed; Mathew, Blesson; Richter, Heiko (American Astronomical Society, 2024-07-10)

We study the kinematics of a pillar, namely G287.76-0.87, using three rotational lines of 12CO(5-4), 12CO(8-7), 12CO(11-10), and a fine structure line of [O i] 63 μm in southern Carina observed by SOFIA/GREAT. This pillar ...

Bonne, Lars; Andersson, B-G; Minchin, Robert; Archana Soam; Yaldaei, Joshua; Kulas, Kristin; Karoly, Janik; Knee, Lewis B. G; Kumar, Siddharth; Roy, Nirupam (American Astronomical Society, 2023-06-01)

Photodissociation regions (PDRs), where the (far-)ultraviolet light from hot young stars interact with the gas in surrounding molecular clouds, provide laboratories for understanding the nature and role of feedback by ...
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 ...
