A photometric and spectroscopic study of the new dwarf spheroidal galaxy in Hercules

open access: yes, 2009
Our aim is to provide as clean and as complete a sample as possible of red giant branch stars that are members of the Hercules dSph galaxy. With this sample we explore the velocity dispersion and the metallicity of the system.

Globular Clusters and Dwarf Spheroidal Galaxies

open access: yes, 2007
Traditionally globular clusters and dwarf spheroidal galaxies have been distinguished by using one or more of the following criteria: (1) mass, (2) luminosity, (3) size, (4) mass-to-light ratio and (5) spread in metallicity.

A Comparison Between the Globular Clusters in NGC 5128 and the Galaxy

open access: yes, 2006
Some of the properties of the globular clusters in NGC 5128 are compared to those of Galactic globular clusters. Assuming the color- metallicity relations that hold for Galactic globular clusters then the metal-poor clusters in NGC 5128 that have [Fe/H] <

Spheroidal and elliptical galaxy radial velocity dispersion determined from Cosmological General Relativity

open access: yes, 2007
Radial velocity dispersion in spheroidal and elliptical galaxies, as a function of radial distance from the center of the galaxy, has been derived from Cosmological Special Relativity.

Keck Studies of M31's Stellar Halo

open access: yes, 2000
We present Keck 10-meter/LRIS spectra of candidate red giants in the halo of M31, located at a projected radius of R=19kpc on the minor axis. These spectroscopic targets have been selected using a combination of UBRI-based and morphological screening to ...

Finding Faint Intermediate-mass Black Holes in the Radio Band

open access: yes, 2004
We discuss the prospects for detecting faint intermediate-mass black holes, such as those predicted to exist in the cores of globular clusters and dwarf spheroidal galaxies.

Searches for HI in the Outer Parts of Four Dwarf Spheroidal Galaxies

open access: yes, 1999
Previous searches for atomic gas in our Galaxy's dwarf spheroidal companions have not been complete enough to settle the question of whether or not these galaxies have HI, especially in their outer parts.

Updated Information on the Local Group

open access: yes, 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 ...
