The Galactic Squeeze: How Aggregate and Highly Dynamical Environments Shape Star Formation in the Local Universe

Wesley Van Kempen, Michelle E. Cluver, Edward N. Taylor +2

We investigate how galaxy evolution varies with environment in the nearby Universe by comparing an ``average'' reference volume in the Southern Galactic Pole (SGP) dataset from \ci…

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…

Mapping dark matter and the emergence of large-scale structure

Jon Loveday, Jochen Liske, Ivan K. Baldry +5

We discuss a potential survey to map dark matter and the emergence of large-scale structure to redshift z ~ 1.5 (baseline) or z~3.5 (with near-IR extension) using a massively multi…

Group Therapy for Halos: Advancing Halo Mass Estimation for Galaxy Groups

Welsey Van Kempen, Michelle E. Cluver, Edward N. Taylor +3

Accurate estimation of dark matter halo masses for galaxy groups is central to studies of galaxy evolution and for leveraging group catalogues as cosmological probes. We present a…

Nessie: A Rust-Powered, Fast, Flexible, and Generalized Friends-of-Friends Galaxy-Group Finder in R and Python

Trystan S. Lambert, A. S. G. Robotham, M. Bravo +4

We introduce Nessie, a galaxy group finder implemented in Rust and distributed as both a Python and R package. Nessie employs the friends-of-friends (FoF) algorithm and requires on…

Deep Extragalactic VIsible Legacy Survey (DEVILS): Galaxy group catalogue for the D10-COSMOS field with 90% spectroscopic redshift completeness

Matías Bravo, Luke J. M. Davies, Aaron S. G. Robotham +6

Large-scale galaxy redshift surveys conducted over the last couple of decades have proven crucial in deepening our understanding of structure growth in the Universe and galaxy evol…
