The abundance and radial distribution of faint and ultra-faint dwarfs in galaxy clusters
Pradyumna Sadhu, Laura V. Sales, Julio F. Navarro +3
Cosmological simulations of galaxy clusters are unable to resolve dwarf galaxies due to limited numerical resolution which drives the artificial disruption of dark matter substruct…
The Spatial Distribution of Globular Cluster Systems in Early Type Galaxies: Estimation Procedure and Catalog of Properties for Globular Cluster Systems Observed with Deep Imaging Surveys
Sungsoon Lim, Eric W. Peng, Patrick Côté +18
We present an analysis of the spatial distribution of globular cluster (GC) systems of 118 nearby early-type galaxies in the Next Generation Virgo Cluster Survey (NGVS) and Mass As…
Measures of luminous and dark matter in galaxies across time
Jonathan Freundlich, Gauri Sharma, Sabine Thater +14
Dark matter is one of the pillars of the current standard model of structure formation: it is assumed to constitute most of the matter in the Universe. However, it can so far only…
The assembly of the most rotationally supported disc galaxies in the TNG100 simulations
Silvio Rodriguez, Valeria A. Cristiani, Laura V. Sales +1
Disc dominated galaxies can be difficult to accommodate in a hierarchical formation scenario like CDM, where mergers are an important growth mechanism. However, observational ev…
The Next Generation Virgo Cluster Survey (NGVS). XXVII.The Size and Structure of Globular Cluster Systems and their Connection to Dark Matter Halos
Sungsoon Lim, Eric W. Peng, Patrick Côté +18
We study the size and structure of globular clusters (GC) systems of 118 early-type galaxies from the NGVS, MATLAS, and ACSVCS surveys. Fitting Sérsic profiles, we investigate the…
Star formation beyond galaxies: widespread in-situ formation of intra-cluster stars
Niusha Ahvazi, Laura V. Sales, Julio F. Navarro +3
We study the fraction of the intra-cluster light (ICL) formed in-situ in the three most massive clusters of the TNG50 simulation, with virial masses M. We…
The Next Generation Virgo Cluster Survey (NGVS). XXX. Ultra-Diffuse Galaxies and their Globular Cluster Systems
Sungsoon Lim, Patrick Côté, Eric W. Peng +14
We present a study of ultra-diffuse galaxies (UDGs) in the Virgo Cluster based on deep imaging from the Next Generation Virgo Cluster Survey (NGVS). Applying a new definition for t…
Dark Matter in Ultra-Diffuse Galaxies in the Virgo Cluster from their Globular Cluster Populations
Elisa Toloba, Sungsoon Lim, Eric Peng +11
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 clust…
