Nature of the absorbing gas associated with a galaxy group at z~0.4 [PDF]
, 2016 We present new MUSE observations of quasar field Q2131-1207 with a log N(HI)=19.50+/-0.15 sub-DLA at z_abs=0.42980. We detect four galaxies at a redshift consistent with that of the absorber where only one was known before this study.

Groups and Protocluster Candidates in the CLAUDS and HSC-SSP Joint Deep Surveys
The Astrophysical Journal, 2022 Using the extended halo-based group finder developed by Yang et al., which is able to deal with galaxies via spectroscopic and photometric redshifts simultaneously, we construct galaxy group and candidate protocluster catalogs in a wide redshift range (0

First results of the XI Groups Project: Studying an unbiased sample of galaxy groups [PDF]
, 2006 X-ray observations of hot, intergalactic gas in galaxy groups provide a useful means of characterizing the global properties of groups. However, X-ray studies of large group samples have typically involved very shallow X-ray exposures or have been based ...

Assessing Colour-dependent Occupation Statistics Inferred from Galaxy Group Catalogues [PDF]
, 2015 We investigate the ability of current implementations of galaxy group finders to recover colour-dependent halo occupation statistics. To test the fidelity of group catalogue inferred statistics, we run three different group finders used in the literature

The PAndAS View of the Andromeda Satellite System. IV. Global Properties
The Astrophysical Journal, 2023 We build a statistical framework to infer the global properties of the satellite system of the Andromeda galaxy (M31) from the properties of individual dwarf galaxies located in the Pan-Andromeda Archaelogical Survey (PAndAS) and the previously ...

The HI content of the Eridanus group of galaxies [PDF]
, 2004 The HI content of galaxies in the Eridanus group is studied using the GMRT observations and the HIPASS data. A significant HI deficiency up to a factor of 2-3 is observed in galaxies in the high galaxy density regions.

ASKAP HI imaging of the galaxy group IC 1459 [PDF]
, 2015 We present HI imaging of the galaxy group IC 1459 carried out with six antennas of the Australian SKA Pathfinder equipped with phased-array feeds. We detect and resolve HI in eleven galaxies down to a column density of $\sim10^{20}$ cm$^{-2}$ inside a ~6
