DINGO/GAMA /WAVES: HI-halo mass relation
Ajay Dev, Martin Meyer, Simon P. Driver +17
We investigate the relation between neutral atomic hydrogen (HI) and dark matter halo mass (HIHM) using observations from the Deep Investigation of Neutral Gas Origins (DINGO) pilo…
SAGAN-VI: When Jets Meet Filaments -- Environmental Imprints on the Growth of Giant Radio Galaxies
Mousumi Mahato, Elmo Tempel, Shishir Sankhyayan +2
Giant radio galaxies (GRGs) represent the largest individual astrophysical structures, rivalling galaxy clusters in physical extent. Understanding how they attain such scales deman…

Greta Toni, Ghassem Gozaliasl, Matteo Maturi +41
Galaxy groups with and up to a few tens of members are the most common galaxy environment, marking the transition between field and massive clu…
CHANCES, the Chilean Cluster Galaxy Evolution Survey: Selection and initial characterisation of clusters and superclusters
Cristóbal Sifón, Alexis Finoguenov, Christopher P. Haines +43
CHANCES, the CHileAN Cluster galaxy Evolution Survey, will study the evolution of galaxies in and around 100 massive galaxy clusters from the local Universe out to , and…
Wide Area VISTA Extra-galactic Survey (WAVES): Unsupervised star-galaxy separation on the WAVES-Wide photometric input catalogue using UMAP and
Todd L. Cook, Behnood Bandi, Sam Philipsborn +13
Star-galaxy separation is a crucial step in creating target catalogues for extragalactic spectroscopic surveys. A classifier biased towards inclusivity risks including spurious sta…
