Environmental Extremists in the Virgo Cluster [PDF]

Symposium - International Astronomical Union, 1999
Many types of galaxy interactions have been posited to occur in clusters, although it remains unclear which processes actually occur, and which ones might help explain the tendency for early type galaxies to inhabit high density environments, or cause the rapid evolution of cluster galaxies (e.g., Dressler et al. 1997). With these questions in mind, we

The Discovery of Blue-cored Dwarf Early-type Galaxies in Isolated Environments

The Astrophysical Journal, 2023
The presence of blue-cored dwarf early-type galaxies (dE(bc)s) in high-density environments supports the scenario of the transformation of infalling late-type galaxies into quiescent dwarf early-type galaxies by environmental effects.

The Trouble with Hubble Types in the Virgo Cluster [PDF]

, 1998
Quantitative measures of central light concentration and star formation activity are derived from R and Halpha surface photometry of 84 bright S0-Scd Virgo Cluster and isolated spiral galaxies.

Dark Matter in Ultra-diffuse Galaxies in the Virgo Cluster from Their Globular Cluster Populations [PDF]

, 2018
We present Keck/DEIMOS spectroscopy of globular clusters (GCs) around the ultra-diffuse galaxies (UDGs) VLSB−B, VLSB−D, and VCC615 located in the central regions of the Virgo cluster. We spectroscopically identify 4, 12, and 7 GC satellites of these UDGs,

The Next Generation Virgo Cluster Survey (NGVS). XXXI. The Kinematics of Intracluster Globular Clusters in the Core of the Virgo Cluster [PDF]

Astrophysical Journal, 2018
Intracluster (IC) populations are expected to be a natural result of the hierarchical assembly of clusters, yet their low space densities make them difficult to detect and study.

Projection effects on pressure profiles: A case study of the Virgo replica [PDF]

EPJ Web of Conferences
An accurate mass calibration of galaxy clusters is a crucial step towards precise constraints on the cosmological parameters σ8 and Ωm from clusters. Cluster masses can be estimated assuming hydrostatic equilibrium, but several physical and observational

Oxygen and nitrogen abundances in Virgo and field spirals [PDF]

, 2001
The oxygen and nitrogen abundances in the HII regions of the nine Virgo spirals of the sample from Skillman et al (1996) and in nine field spiral galaxies are re-determined with the recently suggested P - method.

Expected intermediate mass black holes in the Virgo cluster. II. Late-type galaxies [PDF]

Monthly notices of the Royal Astronomical Society, 2018
The Chandra X-ray Observatory's Cycle 18 Large Program titled "Spiral galaxies of the Virgo Cluster" will image 52 galaxies with the ACIS-S detector. Combined with archival data for an additional 22 galaxies, this will represent the complete sample of 74

The Virgo Cluster [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractIn the era of precision cosmology, the Virgo cluster takes on a new role in the cosmic distance scale. Its traditional role of testing the consistency of secondary distance indicators is replaced by an ensemble of distance measurements within the Local Supercluster, united by a velocity-field model obtained from a reconstruction based on ...
