The hubble constant from infrared surface brightness fluctuation distances
We present a measurement of the Hubble constant H 0 from surface brightness fluctuation
(SBF) distances for 63 bright, mainly early-type galaxies out to 100 Mpc observed with the …

A second galaxy missing dark matter in the NGC 1052 group
The ultra-diffuse galaxy NGC1052-DF2 has a very low velocity dispersion, indicating that it
has little or no dark matter. Here we report the discovery of a second galaxy in this class …

Extending the globular cluster system–halo mass relation to the lowest galaxy masses
High-mass galaxies, with halo masses, reveal a remarkable near-linear relation between
their globular cluster (GC) system mass and their host galaxy halo mass. Extending this …

Wide-field survey of dwarf satellite systems around 10 hosts in the local volume
We present the results of an extensive search for dwarf satellite galaxies around 10 primary
host galaxies in the Local Volume (LV, D< 12 Mpc) using archival CFHT/MegaCam imaging …

The star formation histories of quiescent ultra-diffuse galaxies and their dependence on environment and globular cluster richness
We derive the stellar population parameters of 11 quiescent ultra-diffuse galaxies (UDGs)
from Keck/KCWI data. We supplement these with 14 literature UDGs, creating the largest …

Dark matter-deficient dwarf galaxies form via tidal stripping of dark matter in interactions with massive companions
RA Jackson, S Kaviraj, G Martin… - Monthly Notices of …, 2021 - academic.oup.com
In the standard ΛCDM (Lambda cold dark matter) paradigm, dwarf galaxies are expected to
be dark matter-rich, as baryonic feedback is thought to quickly drive gas out of their shallow …
