Some Global Characteristics of the Galactic Globular Cluster System

, 2003
The relations between the luminosities $M_{V}$, the metallicities $[Fe/H]$, the Galactocentric radii $R$, and the central concentration indices $c$ of Galactic globular clusters are discussed.

The star formation and chemical evolution history of the Fornax dwarf spheroidal galaxy [PDF]

, 2012
We have combined deep photometry in the B, V and I bands from CTIO/MOSAIC of the Sculptor dwarf spheroidal galaxy, going down to the oldest main sequence turn-offs, with spectroscopic metallicity distributions of red giant branch stars. This allows us to

A Census of Dwarf Galaxy Satellites around LMC-mass Galaxy NGC 2403

The Astrophysical Journal
We present the first comprehensive census of the satellite population around a Large Magellanic Cloud stellar-mass galaxy, as part of the Magellanic Analog Dwarf Companions and Stellar Halos (MADCASH) survey. We have surveyed NGC 2403 ( D = 3.0 Mpc) with

VERITAS deep observations of the dwarf spheroidal galaxy Segue 1 [PDF]

, 2012
The VERITAS array of Cherenkov telescopes has carried out a deep observational program on the nearby dwarf spheroidal galaxy Segue 1. We report on the results of nearly 48 hours of good quality selected data, taken between January 2010 and May 2011.

Ultradiffuse Galaxies—A Distinct Population? Dwarf Galaxies in the Coma Cluster and A262 from Deep u′–g′–r′ Wendelstein Imaging Data

The Astrophysical Journal Supplement Series
In this study, we compare the structural parameters of ultradiffuse galaxies (UDGs) to those of other dwarf galaxies and investigate whether UDGs form a distinct population.

γ-ray and ν Searches for Dark-Matter Subhalos in the Milky Way with a Baryonic Potential

Galaxies, 2019
The distribution of dark-matter (DM) subhalos in our galaxy remains disputed, leading to varying γ -ray and ν flux predictions from their annihilation or decay.

Updated Information on the Local Group

, 2000
The present note updates the information published in my recent monograph on \underline{The Galaxies of the Local Group}. Highlights include (1) the addition of the newly discovered Cetus dwarf spheroidal as a certain member of the Local Group, (2) an ...

The Kinematics of Dwarf Spheroidal Galaxies

, 1997
I review observational data on the kinematic properties of dwarf spheroidal galaxies in the halo of the Milky Way and beyond. The present data confirm previous claims that these galaxies have unusually large central velocity dispersions. `Simple' sources of bias such as binary stars, internal atmospheric motions, measurement errors, and small sample ...

LOOKING FOR POSSIBLE DARK MATTER FREE PROGENITORS OF THE CARINA DWARF SPHEROIDAL GALAXY USING N-BODY SIMULATIONS

Momento, 2018
We present a study of the evolution of several different dark matter free possible progenitors of the Carina dSph galaxy, one of the satellites of the Milky Way, using Newtonian numerical N-body simulations.
