Magnetic field Topology and Star Formation in the Cepheus B Filamentary cloud under External Feedback

Panigrahy Sandhyarani, Chakali Eswaraiah, Manash R. Samal +6

We present a detailed study of the Cep B molecular cloud based on sub-mm dust polarization and CO (J=3--2) spectral line observations obtained with SCUBA-2/POL-2 and HARP on…

Evidence for the gravity-driven and magnetically-regularized gas flows feeding the massive protostellar cluster in Cepheus A

Panigrahy Sandhyarani, Chakali Eswaraiah, Di Li +8

The hierarchical interplay among gravity, magnetic fields, and turbulence in forming massive protostellar clusters remains elusive. We present high-resolution (14 arcsec $\si…

ALMASOP: Inner-Envelope Structures of Protostars Driving Nascent Jets

Somnath Dutta, Chin-Fei Lee, Naomi Hirano +15

Protostellar jets provide valuable insight into the evolutionary stage and formation history of star-forming cores in their earliest phases. We investigated the inner envelope stru…

Characterizing the interplay between Galactic star formation and ionization feedback with PRIMA

Annie Zavagno, Delphine Russeil, Paolo Suin +13

Recent results from the James Webb Space Telescope show that nearby spiral galaxies are dominated by the presence of H I and H II bubbles that strongly shape their surrounding medi…

Subaru Hyper-Supreme Cam observations of IC 1396: Source catalogue, member population, and sub-clusters of the complex

Swagat R Das, Saumya Gupta, Jessy Jose +5

To identify member populations of IC 1396, we employ the random forest (RF) classifier of machine learning technique. Random forest classifier is an ensemble of individual decision…

Variation of Dense Gas Mass-Luminosity conversion factor with metallicity in the Milky Way

Sudeshna Patra, Neal J. Evans, Kee-Tae Kim +10

HCN and HCO are the most common dense gas tracers used both in the Milky Way and external galaxies. The luminosity of HCN and HCO lines are converted to a dense g…
