Neutral Atomic Hydrogen in a Star-forming Galaxy 7 Billion Years Ago
Graham Lawrie, Roger Deane, Tariq Blecher +3
Neutral atomic hydrogen (HI) constitutes a key phase of the cosmic baryon cycle, bridging the ionised circumgalactic medium and the star-forming molecular gas. Yet, nearly 75 years…

A MeerKAT study of a neutral hydrogen rich grouping of galaxies with megaparsec-scale filamentary-like structure
G. Lawrie, R. P. Deane, R. Davè
Environmental effects within cosmological overdensities, such as galaxy groups and clusters, have been shown to impact galaxies and their cold gas reservoirs and thereby provide co…
