Spectacular tails of ionized gas in the Virgo cluster galaxy NGC 4569 [PDF]

, 2016
Using MegaCam at the CFHT, we obtained a deep narrow band H alpha+[NII] wide-field image of NGC 4569 (M90), the brightest late-type galaxy in the Virgo cluster.

DARK ENERGY AND KEY PHYSICAL PARAMETERS OF CLUSTERS OF GALAXIES

Odessa Astronomical Publications, 2012
We discuss the physics of clusters of galaxies embedded in the cosmic dark energy background and show that 1) the halo cut-off radius of a cluster like the Virgo cluster is practically, if not exactly, equal to the zero-gravity radius at which the dark ...

The GALEX Ultraviolet Virgo Cluster Survey (GUViCS) III. The Ultraviolet Source Catalogs

, 2014
In this paper we introduce the deepest and most extensive ultraviolet extragalactic source catalogs of the Virgo Cluster area to date. Archival and targeted GALEX imaging is compiled and combined to provide the deepest possible coverage over ~120 deg^2 ...

Quasars and the Virgo cluster [PDF]

Monthly Notices of the Royal Astronomical Society, 1986
On presente les donnees concernant 17 candidats quasars, observes spectroscopiquement. Il semble exister une deficience d'un facteur 2 dans le champ de Virgo. Il ne parait pas y avoir d'association entre les quasars et les galaxies de Virgo.

Structure, mass and distance of the Virgo cluster from a Tolman-Bondi model [PDF]

, 2001
We have applied a relativistic Tolman-Bondi model of the Virgo cluster to a sample of 183 galaxies with measured distances within a radius of 8 degrees from M87.

The observed infall of galaxies towards the Virgo cluster

, 2010
We examine the velocity field of galaxies around the Virgo cluster induced by its overdensity. A sample of 1792 galaxies with distances from the Tip of the Red Giant Branch, the Cepheid luminosity, the SNIa luminosity, the surface brightness fluctuation ...

Discovery of the Kinematic Alignment of Early-type Galaxies in the Virgo Cluster [PDF]

Astrophysical Journal, 2018
Using the kinematic position angles (PAkin), an accurate indicator for the spin axis of a galaxy, obtained from the ATLAS3D integral-field-unit (IFU) spectroscopic data, we discovered that 57 Virgo early-type galaxies tend to prefer the specific PAkin ...

The TRGB–SBF Project. II. Resolving the Virgo Cluster with JWST

The Astrophysical Journal
The Virgo Cluster is the nearest substantial cluster of galaxies to the Milky Way and a cornerstone of the extragalactic distance scale. Here, we present JWST/NIRCam observations that simultaneously cover the cores and halos of 10 galaxies in and around ...
