The Next Generation Virgo Cluster Survey (NGVS). XXXV. First Kinematical Clues of Overly Massive Dark Matter Halos in Several Ultradiffuse Galaxies in the Virgo Cluster

Autor: Elisa Toloba, Laura V. Sales, Sungsoon Lim, Eric W. Peng, Puragra Guhathakurta, Joel Roediger, Kaixiang Wang, J. Christopher Mihos, Patrick Côté, Patrick R. Durrell, Laura Ferrarese

Publikováno v: The Astrophysical Journal, Vol 951, Iss 1, p 77 (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

The Next Generation Virgo Cluster Survey. XXXIII. Stellar Population Gradients in the Virgo Cluster Core Globular Cluster System

Publikováno v: Astrophys.J.
Astrophys.J., 2022, 931 (2), pp.120. ⟨10.3847/1538-4357/ac63cf⟩

We present a study of the stellar populations of globular clusters (GCs) in the Virgo Cluster core with a homogeneous spectroscopic catalog of 692 GCs within a major axis distance $R_{\rm maj} = $ 840 kpc from M87. We investigate radial and azimuthal

The formation of ultradiffuse galaxies in clusters

Autor: Laura V. Sales, Louis Penafiel, Lars Hernquist, Julio F. Navarro, Sungsoon Lim, Eric W. Peng

Publikováno v: Monthly Notices of the Royal Astronomical Society. 494:1848-1858

We use the IllustrisTNG cosmological hydrodynamical simulation to study the formation of ultra-diffuse galaxies (UDGs) in galaxy clusters. We supplement the simulations with a realistic mass-size relation for galaxies at the time of infall into the c

The Color Gradients of the Globular Cluster Systems in M87 and M49

Autor: Yiming Wu, Chengze Liu, Eric W. Peng, Youkyung Ko, Patrick Côté, Rashi Jain, Laura Ferrarese, Xiaohu Yang, Ariane Lançon, Thomas Puzia, Sungsoon Lim

Combining data from the ACS Virgo Cluster Survey (ACSVCS) and the Next Generation Virgo cluster Survey (NGVS), we extend previous studies of color gradients of the globular cluster (GC) systems of the two most massive galaxies in the Virgo cluster, M

Dwarf Galaxies in the MATLAS Survey: Hubble Space Telescope Observations of the Globular Cluster System in the Ultra-diffuse Galaxy MATLAS-2019

Ultra-diffuse galaxies (UDGs) are very low-surface brightness galaxies with large effective radii. Spectroscopic measurements of a few UDGs have revealed a low dark matter content, based on the internal motion of stars or globular clusters (GCs). Thi

The presence of HI gas in galaxies is inextricably linked to their morphology and evolution. This paper aims to understand the HI content of the already identified 2210 dwarfs located in the low-to-moderate density environments of the MATLAS deep ima

We present a photometric study of the dwarf galaxy population in the low to moderate density environments of the MATLAS (Mass Assembly of early-Type gaLAxies with their fine Structures) deep imaging survey. The sample consists of 2210 dwarfs, includi

Stellar shells around galaxies could provide precious insights into their assembly history. However, their formation mechanism remains poorly empirically constrained, regarding in particular the type of galaxy collisions at their origin. We present M
