UCLCHEM 4.0: An open source gas-grain astrochemistry simulation framework
Gijs Vermariën, Serena Viti, Tobias M. Dijkhuis +4
Astrochemical modeling is a key tool for the understanding of the formation and destruction of molecules in the dense gas of the interstellar medium, as observed by modern day obse…
BISTRO Survey: Gravity-Dominated and Magnetically Regulated Star Formation in M17 SW
Mengke Zhao, Keping Qiu, Ji-hyun Kang +27
We present high-resolution magnetic field maps of the M17 SW molecular cloud using JCMT 850 m dust polarization at a scale of 14. The magnetic field exhibits a distinct arc…
The Impact of Radiation Environment on the Evolution and Fragmentation of Protostellar Discs
Matt T. Cusack, Paul C. Clark, Ken Rice +5
We present high-resolution zoom-in simulations of molecular clouds exposed to an interstellar radiation field and cosmic ray ionisation rate up to 1000 times stronger than that of…
NEATH V: the relationship between line emission from dense gas tracers and the star formation rate
F. D. Priestley, P. C. Clark, S. C. O. Glover +5
The Gao-Solomon relationship between the luminosity of the HCN line and the star formation rate (SFR) is observed to remain close to linear over scales ranging from individ…
Assessing Self-Absorbed Molecular Lines as Tracers of Gravitational Collapse
Lillian Y. Cai, Felix D. Priestley, Sarah E. Ragan
Redshifted self-absorption features in molecular lines are commonly interpreted as signatures of gravitational collapse in pre- and protostellar cores. The shape of the line profil…
Dense gas tracers in and between spiral arms: from Giant Molecular Filaments to star-forming clumps
O. Feher, S. E. Ragan, F. D. Priestley +1
Giant Molecular Filaments are opportune locations in our Galaxy to study the star-forming interstellar matter and its accumulation on spatial scales comparable to those now becomin…
