First Mapping Of Prebiotic Molecule CH2NH In A Pre-stellar Core

We present the first spatially resolved map of methanimine CH2NH in the prestellar core L1544 using the IRAM 30m telescope. The 20,2-10,1 line at 127 GHz was mapped with 20″ resolution (∼2800 au), revealing extended CH2NH emission across the core. The peak line intensity coincides with the well-known c-C3H2 peak, while the integrated intensity peaks […]
