PublicationVariable Stars in Local Group Galaxies. VI. The Isolated Dwarfs VV 124 and KKr 25
We present the discovery of variable stars in two isolated dwarf galaxies in the outskirts of the Local Group, VV 124 and KKr 25, using observations with the...

TalkWhat do the neighbors look like? A comparative look at the Milky Way and Andromeda dwarf galaxies
Dwarf galaxies are powerful tools of near-field cosmology and galactic archaeology: their numbers, distribution, and star formation can be linked to both the...

TalkWhat is the Milky Way outer halo made of? High resolution spectroscopy of distant red giants
In a framework where galaxies form hierarchically, extended stellar haloes are predicted to be an ubiquitous feature around Milky Way-like galaxies and to...

PublicationYoung, Blue, and Isolated Stellar Systems in the Virgo Cluster. II. A New Class of Stellar System
We discuss five blue stellar systems in the direction of the Virgo cluster, analogous to the enigmatic object SECCO 1 (AGC 226067). These objects were...
