Velocity Dispersion of 335 Galaxy Clusters Selected from the Sloan Digital Sky Survey: Statistical Evidence for Dynamical Interaction, and Against Ram-Pressure Stripping [PDF]
Mon.Not.Roy.Astron.Soc. 359 (2005) 1415-1420, 2005 There has been plenty of observational evidence of cluster galaxy evolution. However, it has been difficult to identify the origin of the cluster galaxy evolution. Here we show that gravitational interaction/friction between galaxies is the statistically dominant physical mechanism responsible for the cluster galaxy evolution, and that the well-favored

Revealing the nature of star forming blue early-type galaxies at low redshift [PDF]
A&A 583, A103 (2015), 2015 Context: Star forming early-type galaxies with blue optical colours at low redshift can be used to test our current understanding of galaxy formation and evolution. Aims: We want to reveal the fuel and triggering mechanism for star formation in these otherwise passively evolving red and dead stellar systems.

FASEB BioAdvances, Volume 4, Issue 12, Page 775-797, December 2022., 2022 Abstract During initial maternal recognition of pregnancy (MRP), the equine embryo displays a series of unique events characterized by rapid blastocyst expansion, secretion of a diverse array of molecules, and transuterine migration to interact with the uterine surface.

Tidal Disruption of Milky Way Satellites with Shallow Dark Matter Density Profiles
Galaxies, 2016 Dwarf galaxies of the Local Group provide unique possibilities to test current theories of structure formation. Their number and properties have put the broadly accepted cold dark matter model into question, posing a few problems. These problems now seem

The Environment of HII Galaxies revisited [PDF]
, 2013 We present a study of the close (< 200 kpc) environment of 110 relatively local (z< 0.16) HII galaxies, selected from the Sloan Digital Sky Survey (SDSS; DR7).

The Radio Emission of Interacting Galaxies [PDF]
Symposium - International Astronomical Union, 1982 Gravitational interaction is a straightforward interpretation of some of the peculiar optical morphologies shown by galaxies. There have also been attempts to study the effects of a gravitational interaction on the radio continuum emission. Statistically, the central radio sources (inner 1 kpc) in interacting spiral galaxies are about three times ...

The ISM in the z = 6.9 Interacting Galaxies of SPT0311-58
The Astrophysical Journal, 2023 SPT0311-58, a system of two interacting galaxies in the Epoch of Reionization, exists in one of the rarest, most massive dark matter halos theoretically possible in that era.
