The lowest luminosity (L) Milky Way satellite galaxies represent the extreme lower limit of the
galaxy luminosity function. These ultra-faint dwarfs are the oldest, most dark matter …

The development of methods and algorithms to solve the N-body problem for classical,
collisionless, non-relativistic particles has made it possible to follow the growth and …

We use cosmological simulations to study the effects of self-interacting dark matter (SIDM)
on the density profiles and substructure counts of dark-matter haloes from the scales of …

Abstract The SDSS-IV Apache Point Observatory Galactic Evolution Experiment (APOGEE)
survey has obtained high-resolution spectra for thousands of red giant stars distributed …

We present results from the" Mint" resolution DC Justice League suite of Milky Way–like
zoom-in cosmological simulations, which extend our study of nearby galaxies down into the …

Our position inside the Galactic disc has previously prevented us from establishing an
accurate rotation curve (RC). The advent of Gaia and its third data release (Gaia DR3) made …

Satellite galaxies in groups and clusters are more likely to have low star formation rates
(SFRs) and lie on the 'red sequence'than central ('field') galaxies. Using galaxy group/cluster …

We present uniformly measured star formation histories (SFHs) of 40 Local Group (LG) dwarf
galaxies based on color–magnitude diagram (CMD) analysis from archival Hubble Space …

We present proper motions for the Large and Small Magellanic Clouds (LMC and SMC)
based on three epochs of Hubble Space Telescope data, spanning a∼ 7 yr baseline, and …

We present new constraints on the star formation histories of six ultra-faint dwarf galaxies:
Bootes I, Canes Venatici II, Coma Berenices, Hercules, Leo IV, and Ursa Major I. Our …
