Dwarf elliptical galaxies: United and divided [PDF]
Although of humble appearance and often overlooked because of their modest physical sizes and low star densities, dwarf elliptical (dE) galaxies revealed themselves as the most common type of galaxies to exist in the Universe today.

Galaxy Threshing and the Formation of Ultracompact Dwarf Galaxies [PDF]
Recent spectroscopic and morphological observational studies of galaxies around NGC 1399 in the Fornax Cluster (Drinkwater et al. 2000b) have discovered several `ultra-compact dwarf' galaxies with intrinsic sizes of $\sim$ 100 pc and absolute $B$ band magnitudes ranging from -13 to -11 mag.

The impact of accurate distances to dwarf elliptical galaxies on cosmology [PDF]
The Surface Brightness Fluctuation method has been shown to be a powerful distance indicator for dwarf elliptical galaxies to very low surface brightness levels.

Evolution of dwarf galaxies: a dynamical perspective [PDF]
For a rotating galaxy, the inner circular-velocity gradient d_{R}V(0) provides a direct estimate of the central dynamical mass density, including gas, stars, and dark matter. We consider 60 low-mass galaxies with high-quality HI and/or stellar rotation curves (including starbursting dwarfs, irregulars, and spheroidals), and estimate d_{R}V(0) as V(R_d)/

The cores of dwarf galaxy haloes [PDF]
We use N-body simulations to examine the effects of mass outflows on the density profiles of cold dark matter (CDM) halos surrounding dwarf galaxies. In particular, we investigate the consequences of supernova-driven winds that expel a large fraction of the baryonic component from a dwarf galaxy disk after a vigorous episode of star formation.

Faint Dwarf galaxies in nearby WINGS clusters: photometric characterization [PDF]
In the cores of galaxy clusters there is a population of lows-mass stellar systems such as dwarf Early-type galaxies, ultra-compact dwarf galaxies (UCDs) and ultra diffuse dwarf galaxies. We present here the photometric and morphological characterization

Understanding the Extreme Classes of Dwarf Galaxies [PDF]
Most of the research on dwarf galaxies in the past has focused on the detailed properties of nearby systems or the most commonly occurring types of dwarfs.
