Nearby SF spirals in galaxy groups images
We present high-resolution MeerKAT 1.3GHz radio continuum images of star-forming spirals in the nearby galaxy groups around NGC 6221, NGC3256/3263, and NGC 2434. This sample... -
HST/MUSE study of galaxies in Abell 370
We investigate the strong-lensing cluster Abell 370 (A370) using a wide Integral Field Unit (IFU) spectroscopic mosaic from the Multi-Unit Spectroscopic Explorer (MUSE). IFU... -
Circumgalactic medium of galaxies at z~4-5
We present a study of the galaxy environment of nine strong HI+CIV absorption line systems (16.2<log(N(HI))<21.2) spanning a wide range in metallicity at z~4-5, using MUSE... -
HI asymmetries with LVHIS, VIVA, and HALOGAS
We present an analysis of morphological, kinematic, and spectral asymmetries in observations of atomic neutral hydrogen (HI) gas from the Local Volume HI Survey (LVHIS), the VLA... -
Properties of ETGs in compact groups of galaxies
We present results on the study of the stellar population in early-type galaxies (ETGs) belonging to 151 compact groups (CGs). We also selected a field sample composed of 846... -
Cosmicflows-4
With Cosmicflows-4, distances are compiled for 55,877 galaxies gathered into 38,065 groups. Eight methodologies are employed, with the largest numbers coming from the... -
POSSUM RMs and galaxy group associations
We present initial results from the Polarisation Sky Survey of the Universe's Magnetism (POSSUM), analyzing 22817 Faraday Rotation Measures (RMs) with median uncertainties of... -
BTFR's study of ~10000 HyperLEDA galaxies
The interstellar gas in spiral galaxies can constitute a significant fraction of the baryon mass and it has been demonstrated that the sum of stellar and gas components... -
Study of LQGs with SDSS-DR7-QSO data
Correlated orientations of quasar optical and radio polarization, and of radio jets, have been reported on Gpc scales, possibly arising from intrinsic alignment of spin axes.... -
Hydra I cluster study with H I emission
We present results from our analysis of the Hydra I cluster observed in neutral atomic hydrogen (H I) as part of the Widefield ASKAP L-band Legacy All-sky Blind Survey... -
Nuclear classification of local volume galaxies
Nuclear star clusters (NSCs) are a common phenomenon in galaxy centres and are found in a vast majority of galaxies of intermediate stellar mass ~10^9^M_{sun}. Recent... -
Identifying galaxy groups at high redshift I
Identifying galaxy groups from redshift surveys of galaxies plays an important role in connecting galaxies with the underlying dark matter distribution. Current and future... -
MUSE Analysis of Gas around Galaxies II
We present a study of the metal-enriched cool halo gas traced by MgII absorption around 228 galaxies at z~0.8-1.5 within 28 quasar fields from the MUSE Analysis of Gas around... -
Lenses DES J0408-5354 and WGD 2038-4008
tn time-delay cosmography, three of the key ingredients are (1) determining the velocity dispersion of the lensing galaxy, (2) identifying galaxies and groups along the line of... -
2MASS redshift survey galaxy group catalogue
We present the galaxy group catalogue for the recently completed 2MASS Redshift Survey (2MRS; Macri et al. 2019ApJS..245....6M, Cat. J/ApJS/245/6) which consists of 44572... -
HCG 15 radio images
In the context of the life cycle and evolution of active galactic nuclei (AGNs), environment plays a key role. In particular, the over-dense environments of galaxy groups, where...
