The Magellanic Group and the Seven Dwarfs [PDF]
, 2008 The Magellanic Clouds were the largest members of a group of dwarf galaxies that entered the Milky Way (MW) halo at late times. This group, dominated by the LMC, contained ~4% of the mass of the Milky Way prior to its accretion and tidal disruption, but ~

Reignition of star formation in dwarf galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The Local Group hosts a number of star-forming dwarf galaxies that show evidence of periods of little to no star formation. We use a suite of cosmological simulations to study how star formation is reignited in such galaxies.

HST UV Spectroscopy of the Dwarf Starburst Galaxy Pox 186
The Astrophysical Journal, 2023 Studying the galaxies responsible for reionization is often conducted through local reionization-era analogs; however, many of these local analogs are too massive to be representative of the low-mass star-forming galaxies that are thought to play a ...

Dynamics of Dwarf Galaxies Disfavor Stellar-Mass Black Holes as Dark Matter. [PDF]
Physical Review Letters, 2017 We study the effects of black hole dark matter on the dynamical evolution of stars in dwarf galaxies. We find that mass segregation leads to a depletion of stars in the center of dwarf galaxies and the appearance of a ring in the projected stellar ...

RECONCILING DWARF GALAXIES WITH ΛCDM COSMOLOGY: SIMULATING A REALISTIC POPULATION OF SATELLITES AROUND A MILKY WAY–MASS GALAXY [PDF]
, 2016 Low-mass “dwarf” galaxies represent the most significant challenges to the cold dark matter (CDM) model of cosmological structure formation. Because these faint galaxies are (best) observed within the Local Group (LG) of the Milky Way (MW) and Andromeda (

ANGULAR MOMENTUM OF DWARF GALAXIES [PDF]
The Astrophysical Journal Letters, 2016 ABSTRACT We present measurements of baryonic mass and specific angular momentum (sAM) in 14 rotating dwarf Irregular (dIrr) galaxies from the LITTLE THINGS sample.

Chemodynamic evolution of dwarf galaxies in tidal fields [PDF]
, 2016 The mass-metallicity relation shows that the galaxies with the lowest mass have the lowest metallicities. As most dwarf galaxies are in group environments, interaction effects such as tides could contribute to this trend.

CONSTRAINTS ON MACHO DARK MATTER FROM COMPACT STELLAR SYSTEMS IN ULTRA-FAINT DWARF GALAXIES [PDF]
, 2016 I show that a recently discovered star cluster near the center of the ultra-faint dwarf galaxy Eridanus II provides strong constraints on massive compact halo objects (MACHOs) of ≳5 M⊙ as the main component of dark matter.

The Astrophysical JournalWe are entering an era in which we will be able to detect and characterize hundreds of dwarf galaxies within the Local Volume. It is already known that a strong dichotomy exists in the gas content and star formation properties of field dwarf galaxies ...
