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…
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…
ALMA Observations of Molecular Complexity in the Large Magellanic Cloud: Probing the Star-forming Region N160
Amanda Broadmeadow, Marta Sewiło, Lee Mundy +9
Hot cores are small (0.1 pc), dense (10 cm), and hot (100 K) regions around massive protostars and are one of the main production sites of complex org…
Spectuner: A Framework for Automated Line Identification of Interstellar Molecules
Yisheng Qiu, Tianwei Zhang, Thomas Möller +4
Interstellar molecules, which play an important role in astrochemistry, are identified using observed spectral lines. Despite the advent of spectral analysis tools in the past deca…
The physical and chemical structure of Sagittarius B2 VIIIa. Dust and ionized gas contributions to the full molecular line survey of 47 hot cores
T. Möller, P. Schilke, Á. Sánchez-Monge +2
Sagittarius B2 (Sgr B2) is a giant molecular cloud complex in the central molecular zone of our Galaxy hosting several sites of high-mass star formation. The two main centers of ac…
