The galaxy environment in GAMA G3C groups using the Kilo Degree Survey Data Release 3 [PDF]
, 2018 We aim to investigate the galaxy environment in GAMA Galaxy Groups Catalogue (G3C) using a volume-limited galaxy sample from the Kilo Degree Survey Data Release 3.

The Origin of Intergalactic Light in Compact Groups of Galaxies
Universe, 2021 We investigate the origin of intergalactic light (IGL) in close groups of galaxies. IGL is hypothesized to be the byproduct of interaction and merger within compact groups.

Galaxies, 2021 Galaxy groups constitute the most common class of galaxy systems in the known Universe, unique in terms of environmental properties. However, despite recent advances in optical and infrared observations as well as in theoretical research, little is known

Galaxy-galaxy weak-lensing measurement from SDSS: II. host halo properties of galaxy groups [PDF]
, 2017 As the second paper of a series on studying galaxy-galaxy lensing signals using the Sloan Digital Sky Survey Data Release 7 (SDSS DR7), we present our measurement and modelling of the lensing signals around groups of galaxies.

Analysis of the escape in systems with four exit channels
Mathematical Methods in the Applied Sciences, Volume 46, Issue 1, Page 1032-1044, 15 January 2023., 2023 In this paper, we have performed a numerical investigation of the escape of a particle from two different dynamical systems with the same number of exit channels. We have chosen specific values of the parameters of the systems so that the openings of the potential well in both systems are approximately of the same size.

Filaments of galaxies and Voronoi diagrams
Open Astronomy, 2018 The intersections between a spherical shell and the faces of Voronoi polyhedrons are numerically evaluated. The nodes of these intersections are the points that share the same distances from three nuclei.

Evolution of Galaxy Types and HI Gas Contents in Galaxy Groups [PDF]
The Astrophysical Journal.862(2018)48-62, 2018 Using the group crossing time $t_{\rm c}$ as an age indicator for galaxy groups, we have investigated the correlation between $t_{\rm c}$ and the group spiral fraction, as well as between $t_{\rm c}$ and the neutral hydrogen gas fraction of galaxy groups.

The HI mass function of group galaxies in the ALFALFA survey [PDF]
, 2020 We estimate the HI mass function (HIMF) of galaxies in groups based on thousands of ALFALFA (Arecibo Legacy Fast ALFA survey) HI detections within the galaxy groups of four widely used SDSS (Sloan Digital Sky Survey) groups catalogues. Although differences between the catalogues mean that there is no one definitive group galaxy HIMF, in general we find

Low Mass Group Environments have no Substantial Impact on the Circumgalactic Medium Metallicity [PDF]
, 2020 We explore how environment affects the metallicity of the circumgalactic medium (CGM) using 13 low mass galaxy groups (2-5 galaxies) at $\langle z_{abs}\rangle=0.25$ identified near background quasars.
