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…

Jets and Outflows in Young Stellar Objects with the SKAO

Giovanni Sabatini, Gemma Busquet, Carlos Carrasco-González +48

Jets and outflows are ubiquitous phenomena associated with the formation of young stellar objects (YSOs). They play a crucial role in removing angular momentum from the accreting s…

Star Formation Drives Production of Low Energy Cosmic Rays

Ningyu Tang, Jiahao Liu, Di Li +18

For over a century, the origin of low-energy cosmic rays (LECRs), the dominant heaters and ionizers of dense interstellar gas, remains elusive owing to solar modulation and uncerta…

Chemical complexity in star formation induced by stellar feedback: cores shock-formed by the supernova remnant W44

G. Cosentino, I. Jiménez-Serra, F. Fontani +8

Low-velocity shocks from Supernova Remnants (SNRs) may set the physical and chemical conditions of star formation in molecular clouds. Recent evidence suggests that the Sun might h…

CO Depletion in Infrared Dark Clouds

G. Cosentino, J. C. Tan, C. Gainey +10

Infrared Dark Clouds (IRDCs) are cold, dense structures representative of the initial conditions of star formation. Many studies of IRDCs employ CO to investigate cloud dynamics. H…

Cosmic-ray ionisation rate in low-mass cores: the role of the environment

E. Redaelli, S. Bovino, G. Sabatini +6

Context: Cosmic rays drive several key processes for the chemistry and dynamical evolution of star-forming regions. Their effect is quantified mainly by means of the cosmic-ray ion…
