Radio galaxy feedback in X-ray selected groups from COSMOS: the effect on the ICM [PDF]
, 2010 We quantify the importance of the mechanical energy released by radio-galaxies inside galaxy groups. We use scaling relations to estimate the mechanical energy released by 16 radio-AGN located inside X-ray detected galaxy groups in the COSMOS field.

AGN Feedback in Groups and Clusters of Galaxies
, 2022 AGN feedback stands for the dramatic impact that a SMBH can make on its environment. It has become an essential element of models that describe the formation and evolution of baryons in massive virialized halos. The baryons' radiative losses in the cores of these halos might lead to massive cooling and vigorous star formation on the order of 10-1000 ...

X-ray bright groups and their galaxies [PDF]
, 2002 Combining X-ray data from the ROSAT PSPC and optical data drawn from the literature, we examine in detail the relationship between the X-ray and optical properties of X-ray bright galaxy groups. We find a relationship between optical luminosity and X-ray

Galaxy pairs in the 2dF survey ¿ II. Effects of interactions on star formation in groups and clusters [PDF]
, 2004 We assess the effects of galaxy-galaxy interactions on star formation (SF) by analysing pairs in groups and clusters of galaxies with virial masses in the range 10 13 -10 15 M ○. extracted from the 2dF Galaxy Redshift Survey (2dFGRS). We find that galaxy

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.

The Astrophysical Journal, 2023 We use the DR9 of the DESI legacy imaging survey and SDSS galaxy groups to measure the conditional luminosity function (CLF) for groups with halo mass M _h ≥ 10 ^12 M _⊙ and redshift 0.01 ≤ z ≤ 0.08, down to a limiting r -band magnitude of M _r = −10 to −

Galaxy Collisions, Gas Stripping and Star Formation in the Evolution of Galaxies
, 2004 A review of gravitational and hydrodynamical processes during formation of clusters and evolution of galaxies is given. Early, at the advent of N-body computer simulations, the importance of tidal fields in galaxy encounters has been recognized.

The properties of the hot gas in galaxy groups and clusters from ID hydrodynamical simulations - I. Cosmological infall models [PDF]
, 1997 We report the results of 1-D hydrodynamical modelling of the evolution of gas in galaxy clusters. We have incorporated many of the effects missing from earlier 1-D treatments: improved modelling of the dark matter and galaxy distributions, cosmologically
