A misaligned protostellar disk fed by gas streamers in a barred spiral-like massive dense core
Xiaofeng Mai, Tie Liu, Xunchuan Liu +42
High-mass stars, born in massive dense cores (MDCs), profoundly impact the cosmic ecosystem through feedback processes and metal enrichment, yet little is known about how MDCs asse…
Characterizing the interplay between Galactic star formation and ionization feedback with PRIMA
Annie Zavagno, Delphine Russeil, Paolo Suin +13

Star formation efficiency and scaling relations in parsec-scale cluster-forming clumps
V. Rawat, M. R. Samal, A. Zavagno +5
Numerical simulations predict that clumps (1 pc) should form stars at high efficiency to produce bound star clusters. We conducted a statistical study of 17 nearby cluster-fo…
The Molecular and Atomic Hydrogen Gas Content of the Boötes Void galaxy CG 910
Ekta Sharma, Prerana Biswas, Mousumi Das +1
Void galaxies are located in the most underdense environments of the Universe, where the number density of galaxies is extremely low. They are, hence, good targets for studying the…
The ALMA-ATOMS survey: Vibrationally excited HCN lines in hot cores
Li Chen, Sheng-Li Qin, Tie Liu +26
Interstellar molecules are excellent tools for studying the physical and chemical environments of massive star-forming regions. In particular, vibrationally excited HCN (HC…
Research on the Interstellar Medium and Star Formation in the Galaxy: An Indian Perspective
Bhaswati Mookerjea, Maheswar G., Kinsuk Acharyya +24
Although the star formation process has been studied for decades, many important aspects of the physics involved remain unsolved. Recent advancement of instrumentation in the infra…
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…
JWST-ALMA Study of a Hub-Filament System in the Nascent Phase
N. K. Bhadari, L. K. Dewangan, O. R. Jadhav +7
Star clusters, including high-mass stars, form within hub-filament systems (HFSs). Observations of HFSs that remain unaffected by feedback from embedded stars are rare yet crucial…
Fate and detectability of rare gas hydride ions in nova ejecta: A case study with nova templates
Milan Sil, Ankan Das, Ramkrishna Das +6
HeH was the first heteronuclear molecule to form in the metal-free Universe after the Big Bang. The molecule gained significant attention following its first circumstellar dete…
