Chemical complexity in feedback from supernova remnants: first detection of PO+ in IC443 and W44
G. Cosentino, F. Priestley, S. Scibelli +1
Supernova remnant (SNR) may shape the physical and chemical properties of star formation. By releasing refractory elements into the gas phase, they inject material of pre-biotic re…
Low cosmic-ray ionisation at parsec scales in G035.39-00.33
Andrea Socci, Ashley Barnes, Jaime Pineda +11
Cosmic rays (CRs) regulate the chemical evolution of the gas and its coupling to the magnetic field in the densest and coldest regions of the interstellar medium (ISM). However, th…
SiO emission in the filamentary Infrared Dark Cloud G035.39-00.33: An ALMA view
Rong Liu, Izaskun Jiménez-Serra, Giuliana Cosentino +8
Filamentary infrared dark clouds (IRDCs) are believed to represent the initial conditions for massive star and cluster formation. We investigate the IRDC G035.39-00.33 using SiO, H…
The Emergence of Prebiotic Chemistry in the ISM
Izaskun Jimenez-Serra, Giuliana Cosentino, Francisco Montenegro-Montes +22
Contrary to popular belief, the interstellar medium (ISM) is not empty; it is filled with atoms, dust particles, and molecules. Some of these molecules may have been the very build…
The role of supernova remnants for the emergence of pre-biotic chemistry in molecular clouds
Giuliana Cosentino, Izaskun Jiménez-Serra, Laura Colzi +11
There is growing evidence that the Sun might have formed within a nebula impacted by at least one SNR. In this scenario, ejecta and shocks from SNRs may have provided the elements…
