Chemical complexity in feedback from supernova remnants: first detection of PO+ in IC443 and W44
G. Cosentino, F. Priestley, S. Scibelli +1

JWST/NIRCam obtained high angular-resolution (0.05-0.1''), deep near-infrared 1--5 micron imaging of Supernova (SN) 1987A taken 35 years after the explosion. In the NIRCam images,…
NH(1-0) as a tracer of dense gas in and between spiral arms
O. Feher, S. E. Ragan, F. D. Priestley +2
Recent advances in identifying giant molecular filaments in galactic surveys allow us to study the interstellar material and its dense, potentially star forming phase on scales com…
From total destruction to complete survival: Dust processing at different evolutionary stages in the supernova remnant Cassiopeia A
Florian Kirchschlager, Nina Sartorio, Ilse De Looze +3
The expanding ejecta of supernova remnants (SNRs) are believed to form dust in dense clumps of gas. Before the dust can be expelled into the interstellar medium and contribute to t…
The dynamic centres of infrared-dark clouds and the formation of cores
Andrew J. Rigby, Nicolas Peretto, Michael Anderson +7
High-mass stars have an enormous influence on the evolution of the interstellar medium in galaxies, so it is important that we understand how they form. We examine the central clum…

Heavy Black Hole Seed Formation in High-z Atomic Cooling Halos
Lewis R. Prole, John A. Regan, Simon C. O. Glover +3
Halos with masses in excess of the atomic limit are believed to be ideal environments in which to form heavy black hole seeds with masses above 10^3 Msun. In cases where the H_2 fr…
NEATH II: NH as a tracer of imminent star formation in quiescent high-density gas
F. D. Priestley, P. C. Clark, S. C. O. Glover +4
Star formation activity in molecular clouds is often found to be correlated with the amount of material above a column density threshold of . Attempt…
Population III star formation: multiple gas phases prevent the use of an equation of state at high densities
Lewis R. Prole, Paul C. Clark, Felix D. Priestley +2
Advanced primordial chemistry networks have been developed to model the collapse of metal-free baryonic gas within the gravitational well of dark matter (DM) halos and its subseque…
Non-Equilibrium Abundances Treated Holistically (NEATH): the molecular composition of star-forming clouds
F. D. Priestley, P. C. Clark, S. C. O. Glover +4
