Distance measurements from the internal dynamics of globular clusters: Application to the Sombrero galaxy (M104)

Katja Fahrion, Michael A. Beasley, Anastasia Gvozdenko +7

Globular clusters (GCs) are dense star clusters found in all massive galaxies. Recent work has established that they follow a tight relation between their internal stellar velocity…

STRRINGS: STReams in Residual Images of Nearby GalaxieS

E. Sola, D. Chemaly, V. Belokurov +11

Tidal features from galaxy mergers, particularly stellar streams, offer valuable insights into galaxy assembly and dark matter halo properties. This paper aims to identify a large…

An LBT view of the co-rotating group of galaxies around NGC 2750: Deep imaging and new satellite candidates

S. Taibi, M. S. Pawlowski, O. Müller +6

Some galaxies such as the Milky Way and Andromeda display coherently rotating satellite planes, posing tensions with cosmological simulations. NGC 2750 has emerged as an additional…

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…

Discovery of a Rare Group of Dwarf Galaxies in the Local Universe

Sanjaya Paudel, Cristiano G. Sabiu, Suk-Jin Yoon +3

We report the discovery of a rare isolated group of five dwarf galaxies located at z = 0.0086 ( = 36 Mpc). All member galaxies are star-forming, blue, and gas-rich with in…
