Shell Structure in the Fornax Dwarf Spheroidal Galaxy

, 2015
We present initial results from a wide-field photometric survey of the Fornax dwarf spheroidal (dSph) galaxy. The focus here is on a small overdensity of stars located approximately 17' (670 pc in projection) from the center of Fornax. Based

Feeding and feedback in dwarf galaxies (FeeD)

Astronomy & Astrophysics
Feeding and feedback regulated by supermassive black holes play a central role in galaxy growth and evolution, yet these processes remain poorly understood in low-mass galaxies.

Environment Matters: Predicted Differences in the Stellar Mass–Halo Mass Relation and History of Star Formation for Dwarf Galaxies

The Astrophysical Journal
We 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 ...

A spectroscopic binary in the Hercules dwarf spheroidal galaxy

, 2013
We present the radial velocity curve of a single-lined spectroscopic binary in the faint Hercules dwarf spheroidal (dSph) galaxy, based on 34 individual spectra covering more than 2 yr of observations.

Intermediate Mass Ratio Inspirals in Milky Way Galaxies

The Astrophysical Journal
A consequence of a nonzero occupation fraction of massive black holes (MBHs) in dwarf galaxies is that these MBHs can become residents of larger galaxy halos via hierarchical merging and tidal stripping.

Towards AMR Simulations of Galaxy Formation [PDF]

, 2010
Numerical simulations present a fundamental building block of our modern theoretical understanding of the Universe. As such the work in this thesis is primarily concerned with understanding fundamental differences that lie between the different ...

Chemical Cartography of the Sagittarius Stream with Gaia

The Astrophysical Journal
The stellar stream connected to the Sagittarius (Sgr) dwarf galaxy is the most massive tidal stream that has been mapped in the Galaxy, and is the dominant contributor to the outer stellar halo of the Milky Way (MW).

GHOSTS I : a new faint very isolated dwarf galaxy at D = 12 ± 2 Mpc.

, 2014
We report the discovery of a new faint dwarf galaxy, GHOSTS I, using HST/ACS data from one of our GHOSTS (Galaxy Halos, Outer disks, Substructure, Thick disk, and Star clusters) fields.
