The Astrophysical Journal, 2023 We present Keck/DEIMOS spectroscopy of the first complete sample of ultradiffuse galaxies (UDGs) in the Virgo cluster. We select all UDGs in Virgo that contain at least 10 globular cluster (GC) candidates and are more than 2.5 σ outliers in scaling ...

AN OVERMASSIVE DARK HALO AROUND AN ULTRA-DIFFUSE GALAXY IN THE VIRGO CLUSTER [PDF]
, 2016 Ultra-diffuse galaxies (UDGs) have the sizes of giants but the luminosities of dwarfs. A key to understanding their origins comes from their total masses, but their low surface brightnesses ( &mgr; ( V ) ≥ ?> 25.0) generally prohibit dynamical studies ...

TIDAL STRIPPING OF GLOBULAR CLUSTERS IN THE VIRGO CLUSTER [PDF]
The Astrophysical Journal, 2009 With the aim of finding evidence of tidal stripping of globular clusters (GCs) we analysed a sample of 13 elliptical galaxies taken from the ACS Virgo Cluster Survey (VCS). These galaxies belong to the main concentration of the Virgo cluster (VC) and present absolute magnitudes $-18 ...

Alone on a wide wide sea. The origin of SECCO 1, an isolated star-forming gas cloud in the Virgo cluster [PDF]
, 2018 SECCO1 is an extremely dark, low-mass (M_star=10^5 M_sun), star-forming stellar system lying in the Low Velocity Cloud (LVC) substructure of the Virgo cluster of galaxies, and hosting several HII regions.

DARK ENERGY AND KEY PHYSICAL PARAMETERS OF CLUSTERS OF GALAXIES
Acta Polytechnica, 2013 We study physics of clusters of galaxies embedded in the cosmic dark energy background. The equilibrium and stability of polytropic spheres with equation of state of the matter P = Kpγ, γ = 1 + 1/n, in presence of a non-zero cosmological ...

The Principal Axis of the Virgo Cluster [PDF]
, 2000 Using accurate distances to individual Virgo cluster galaxies obtained by the method of Surface Brightness Fluctuations, we show that Virgo's brightest ellipticals have a remarkably collinear arrangement in three dimensions.

Automated detectionof very low surface brightness galaxiesin the Virgo cluster [PDF]
, 2018 We report the automatic detection of a new sample of very low surface brightness (LSB) galaxies, likely members of the Virgo cluster. We introduce our new software, {\tt DeepScan}, that has been designed specifically to detect extended LSB features ...

The ACS Virgo Cluster Survey [PDF]
Highlights of Astronomy, 2005 AbstractWe describe the ACS Virgo Cluster Survey, an HST imaging survey of early-type galaxies in the Virgo Cluster. Multi-color ACS images for one hundred member galaxies, spanning a range of 450 in luminosity, are being used to study the central regions of these galaxies, their globular cluster systems, and the three-dimensional structure of Virgo ...

The Spectroscopy and H-band Imaging of Virgo Cluster Galaxies (SHIVir) Survey: Scaling Relations and the Stellar-to-total Mass Relation [PDF]
, 2017 We present parameter distributions and fundamental scaling relations for 190 Virgo cluster galaxies in the SHIVir survey. The distribution of galaxy velocities is bimodal about Vcirc ∼ 125 km s−1, hinting at the existence of dynamically unstable modes in
