Stellar Populations of the Outer Milky-Way Halo

Proceedings of the International Astronomical Union, 2017
AbstractThe stellar spheroidal components of the Milky-Way contain the oldest and most metal poor of its stars. Inevitably the processes governing the early stages of Galaxy evolution are imprinted upon them. According to the currently favoured hierarchical bottom-up scenario of galaxy formation, these components, specially the Galactic halo, are the ...

Stellar Substructure in the Halos of the Milky Way and M31

Proceedings of the International Astronomical Union, 2017
AbstractDedicated wide-field surveys have uncovered a variety of debris features and stellar streams in the halos of the Milky Way and M31. I briefly compare these perspectives and discuss how observations of the peripheral regions of M31 can help shape our current understanding of the Milky Way.

Stellar Archaeology in the Milky Way Halo: Variable Stars and Stellar Populations in the New Milky Way Satellites Discovered by the SDSS

AIP Conference Proceedings, 2009
We present results of a project devoted to the extensive survey of the ultra‐faint Milky Way dwarf spheroidal satellites recently discovered by the SDSS (Bootes I, Ursa Major II, Coma, Hercules, Canes Venatici I, Canes Venatici II, Leo IV), that we are monitoring for variability using time‐series multiband observations collected at a variety of ...

The Assembly History Of The Milky Way Stellar Halo [PDF]

The Milky Way as a galaxy is one that holds particular interest to me because it is the one in which we exist. Understanding the origins of the Galaxy is key to figuring out our importance in the Universe and whether there is a purpose for our existence or whether we are merely a series of accidents.

Stellar archaeology in the Milky Way halo. Variable stars and stellar populations in the new Milky Way ultra-faint dwarfs

2020
We summarize results from the photometric survey of a number of ultra-faint dwarf satellites of the Milky Way. We are studying these systems in a systematic way to characterize their stellar populations and structural parameters, as well as their variable star content, with the aim of deriving hints on the formation process of the Galactic halo.
