In Pursuit of the Least Luminous Galaxies

Advances in Astronomy, 2010
The dwarf galaxy companions to the Milky Way are unique cosmological laboratories. With luminosities as low as 10−7LMW, they inhabit the lowest mass dark matter halos known to host stars and are presently the most direct tracers of the distribution, mass

Gas depletion in Local Group dwarfs on ~250 kpc scales: Ram pressure stripping assisted by internal heating at early times

, 2011
A recent survey of the Galaxy and M31 reveals that more than 90% of dwarf galaxies within 270 kpc of their host galaxy are deficient in HI gas. At such an extreme radius, the coronal halo gas is an order of magnitude too low to remove HI gas through ram ...

Mapping Corporate Investments Between China and Europe in an Era of Geoeconomic Competition

JCMS: Journal of Common Market Studies, Volume 63, Issue 3, Page 932-963, May 2025.
Abstract The consolidation of geoeconomic competition puts core aspects of global economic interdependence, such as the mutual China‐EU investment relationship, under increased pressure. Headlines about ‘derisking’, ‘decoupling’ or ‘deglobalization’ dominate current debates but tend to be overly simplistic.

The Outer Edges of Dwarf Irregular Galaxies: Stars and Gas

, 2002
We have in recent years come to view dwarf galaxy evolution in the broader context of the cosmic evolution of large-scale structure. Dwarf galaxies, as the putative building blocks of hierarchical galaxy formation, and also as the most numerous galaxies ...

A Search for Faint Resolved Galaxies Beyond the Milky Way in DES Year 6: A New Faint, Diffuse Dwarf Satellite of NGC 55

The Astrophysical Journal
We report results from a systematic wide-area search for faint dwarf galaxies at heliocentric distances from 0.3 to 2 Mpc using the full 6 yr of data from the Dark Energy Survey (DES).

The early-type dwarf galaxy population of the Centaurus cluster

, 2009
We present a photometric study of the early-type dwarf galaxy population of the Centaurus cluster, aiming at investigating the galaxy luminosity function (LF) and galaxy scaling relations down to the regime of galaxies with M_V~-10 mag. On deep VLT/FORS1

Forecasts for Galaxy Formation and Dark Matter Constraints from Dwarf Galaxy Surveys

The Astrophysical Journal
The abundance of faint dwarf galaxies is determined by the underlying population of low-mass dark matter (DM) halos and the efficiency of galaxy formation in these systems. Here, we quantify potential galaxy formation and DM constraints from future dwarf

Discovery of a tidal dwarf galaxy in the Leo Triplet

, 2014
We report discovery of a dwarf galaxy in the Leo Triplet. Analysis of the neutral hydrogen distribution shows that it rotates independently of the tidal tail of NGC 3628, with a radial velocity gradient of 35-40 km s$^{-1}$ over approximately 13 kpc. The
