A UNIVERSAL MASS PROFILE FOR DWARF SPHEROIDAL GALAXIES?

The Astrophysical Journal, 2009
Replacement provides corrections to values of half-light radii adopted for eight classical dSphs, including revised tables and figures (conclusions are unchanged).

Are Milky-Way dwarf-spheroidal galaxies dark-matter free?

, 2019
International audienceWe have found that the high velocity dispersions of dwarf spheroidal galaxies (dSphs) can be well explained by Milky Way (MW) tidal shocks, which reproduce precisely the gravitational acceleration previously attributed to dark ...

Exploring the Evolution of a Dwarf Spheroidal Galaxy with SPH Simulations. II. AGN Feedback

The Astrophysical Journal
We investigate active galactic nucleus (AGN) feedback from an intermediate-mass black hole at the center of a dwarf spheroidal galaxy, by performing isolated galaxy simulations using a modified version of the GADGET-3 code. We consider Leo II (PGC 34176)

Dynamics of the Fornax Dwarf Spheroidal Galaxy [PDF]

Symposium - International Astronomical Union, 1987
The mass to light ratio of the inner parts of the Fornax system is 3.2 ± 1.1. Its major axis rotation is only 3.4 ± 2.4 km s-1 over ± 1 kpc, which argues against its origin as a stripped dwarf irregular.

Stellar Density Profiles of Dwarf Spheroidal Galaxies: Posterior Distributions

, 2019
This archive contains samples from the posterior distributions of our 3-plummer, 1-plummer, 3-steeper and 1-steeper fits for 38 dwarf spheroidal galaxies.

Exploring the Structures and Substructures of the Andromeda Satellite Dwarf Galaxies Cassiopeia III, Perseus I, and Lacerta I

The Astronomical Journal, 2023
We present results from wide-field imaging of the resolved stellar populations of the dwarf spheroidal galaxies Cassiopeia III (And XXXII) and Perseus I (And XXXIII), two satellites in the outer stellar halo of the Andromeda galaxy (M31).

Structural properties of dwarf ellipticals and the connection with (ordinary) elliptical galaxies

, 2016
This article reviews the popular reasons for the belief that dwarf elliptical galaxies and (ordinary) elliptical galaxies are distinct and separate species.
