No Evidence of Asymmetrically Enhanced Star Formation in Infalling Galaxies in UNIONS

The Astrophysical Journal
Ram pressure stripping is a well-known environmental quenching mechanism that removes gas from galaxies infalling into groups and clusters. In some extreme examples of ram pressure stripping, galaxies with extended gas tails show evidence of enhanced ...

Core to Cosmic Edge: SIMBA-C’s New Take on Abundance Profiles in the Intragroup Medium at z = 0

Universe
We employ the simba-c cosmological simulation to study the impact of its upgraded chemical enrichment model (Chem5) on the distribution of metals in the intragroup medium (IGrM).

The Metal Content of the Hot Atmospheres of Galaxy Groups

Universe, 2021
Galaxy groups host the majority of matter and more than half of all the galaxies in the Universe. Their hot (107 K), X-ray emitting intra-group medium (IGrM) reveals emission lines typical of many elements synthesized by stars and supernovae.

Compact groups in the UZC galaxy sample

, 2002
Applying an automatic neighbour search algorithm to the 3D UZC galaxy catalogue (Falco 1999) we have identified 291 compact groups (CGs) with redshifts between 1000 and 10000 km/s.

Copper Stress Response of Antibiotic‐Resistant and Copper‐Tolerant Enterococcus faecium and the Antibacterial Efficacy of Functionalized Copper Surfaces

Advanced Materials Interfaces, EarlyView.
This study examines how different laser‐patterned copper and brass surfaces, including copper coatings, affect the survival of vancomycin‐resistant Enterococcus faecium. Using microscopy and genome analysis, the results show that copper tolerance varies between strains and can increase after vancomycin exposure.

Tracing the Formation History of Intrahalo Light with Horizon Run 5

The Astrophysical Journal
We investigate the formation history of intrahalo light (IHL) using the high-resolution (∼1 kpc), large-scale (∼1 Gpc) cosmological hydrodynamical simulation Horizon Run 5 (HR5).

Segregation Effects According to the Evolutionary Stage of Galaxy Groups [PDF]

, 2010
We study segregation phenomena in 57 groups selected from the 2PIGG catalog of galaxy groups. The sample corresponds to those systems located in areas of at least 80% redshift coverage out to 10 times the radius of the groups.

Satellite luminosities in galaxy groups [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
Halo model interpretations of the luminosity dependence of galaxy clustering assume that there is a central galaxy in every sufficiently massive halo, and that this central galaxy is very different from all the others in the halo. The halo model decomposition makes the remarkable prediction that the mean luminosity of the non-central galaxies in a halo
