First mapping of prebiotic molecule CH2NH in a pre-stellar core
Yuxin Lin, Silvia Spezzano, Olli Sipilä +2
We present the first spatially resolved map of methanimine CH2NH in the prestellar core L1544 using the IRAM 30m telescope. The 2-1 line at 127 GHz was mapped with…
High deuteration of methanol in L1544
S. Spezzano, W. Riedel, P. Caselli +7
Isotopic fractionation is a very powerful tool to follow the evolution of material from one stage to the next in the star-formation process. Pre-stellar cores exhibit some of the h…
Tails of Gravity: Persistence of Star Formation in the CMZ Environment
Linjing Feng, Sihan Jiao, Fengwei Xu +16
We characterize star-forming gas in six molecular clouds (Sgr B1-off, Sgr B2, Sgr C, the 20 km s and 50 km s molecular clouds, and the Brick) in the Galactic central…
Deep Andromeda JCMT-SCUBA2 Observations. The Submillimeter Maps and Giant Molecular Clouds
Sihan Jiao, Jingwen Wu, Hauyu Baobab Liu +23
We have carried out unprecedentedly deep, nearly confusion-limited JCMT-SCUBA2 mapping observations on the nearest spiral galaxy, M31 (Andromeda). The 850 m image with a 5…
Nascent chemical complexity in prestellar core IRAS 16293E: complex organics and deuterated methanol
Samantha Scibelli, Maria N. Drozdovskaya, Paola Caselli +5
Prestellar cores represent early sites of low-mass ( few M) star and planet formation and provide insight into initial chemical conditions of complex organic mole…
Why is the Star Formation Rate Proportional to Dense Gas Mass?
Sihan Jiao, Fengwei Xu, Hauyu Baobab Liu +14
One of the most profound empirical laws of star formation is the Gao-Solomon relation, a linear correlation between the star formation rate (SFR) and the dense molecular gas mass.…
Gravitationally Bound Gas Determines Star Formation in the Galaxy
Sihan Jiao, Jingwen Wu, Zhi-Yu Zhang +13
Stars form from molecular gas under complex conditions influenced by multiple competing physical mechanisms, such as gravity, turbulence, and magnetic fields. However, accurately i…
Laboratory rotational spectroscopy leads to the first interstellar detection of singly deuterated methyl mercaptan (CHDSH)
Hayley A. Bunn, Silvia Spezzano, Laurent H. Coudert +8
We report an extensive rotational spectroscopic analysis of singly deuterated methyl mercaptan (CHDSH) using both millimeter and far-infrared synchrotron spectra to achieve a…
