Context. Apertif is a multi-beam receiver system for the Westerbork Synthesis Radio Telescope that operates at 1.1-1.5 GHz, which overlaps with various radio services, resulting in…
Sociology and hierarchy of voids: A study of seven nearby CAVITY galaxy voids and their dynamical CosmicFlows-3 environment
H. M. Courtois, R. van de Weygaert, M. Aubert +14
Context. The present study addresses a key question related to our understanding of the relation between void galaxies and their environment: the relationship between luminous and…
HALOGAS: Strong Constraints on the Neutral Gas Reservoir and Accretion Rate in Nearby Spiral Galaxies
P. Kamphuis, E. Jütte, G. H. Heald +11
Galaxies in the local Universe are thought to require ongoing replenishment of their gas reservoir in order to maintain the observed star formation rates. Cosmological simulations…

Seeing the forest and the trees: a radio investigation of the ULIRG Mrk 273
Pranav Kukreti, Raffaella Morganti, Marco Bondi +19
Galaxy mergers have been observed to trigger nuclear activity by feeding gas to the central supermassive black hole. One such class of objects are Ultra Luminous InfraRed Galaxies…
Using EAGLE simulations to study the effect of observational constraints on the determination of HI asymmetries in galaxies
