Unveiling the enigma of the Nakashima-Deguchi object (IRAS 19312+1950): a candidate Orion KL analog
Y. Gong, K. M. Menten, T. KamiÅski +5
The Nakashima-Deguchi object (NDO; aka IRAS 19312+1950) has been recognized as an enigmatic object, exhibiting characteristics of both an evolved star and a star-forming region. Ho…
ALMAGAL IX. The chemical complexity of AG318.9477-00.1960: A line-identification template for ALMAGAL
J. Allande, M. T. Beltrán, V. M. Rivilla +36
We present a detailed molecular line analysis of one of the most chemically rich cores in the ALMAGAL sample, the high-mass core~9 in the AG318.9477-00.1960 clump (AG318-c9), locat…
ALMAGAL VIII. Early phases of triggered star formation in source AG286.07161.8229
C. Mininni, S. Molinari, W. J. Kim +50
Several theoretical and observational studies have shown that new waves of triggered star-formation can be induced by the feedback from newly formed massive protostars, due to the…
ALMAGAL VII. Cataloging Hierarchical Mass Structure from Cores to Clumps across the Galactic Disk
Jennifer Wallace, Taevis Kolz, Cara Battersby +42
Investigating the multi-scale fragmentation of dense clumps into compact cores is essential for understanding the processes that govern the initial distribution of mass in stellar…
Spectuner-D1: Spectral Line Fitting of Interstellar Molecules Using Deep Reinforcement Learning
Yisheng Qiu, Tianwei Zhang, Tie Liu +6
Spectral lines from interstellar molecules provide crucial insights into the physical and chemical conditions of the interstellar medium. Traditional spectral line analysis relies…
Properties of masers and their associated sources in Sagittarius B2
Nazar Budaiev, Adam Ginsburg, Ciriaco Goddi +5
We present high-resolution Karl G. Jansky Very Large Array observations of the 22 GHz maser line in the extended Sagittarius B2 cloud. We detect 499 …
