The chemical evolution of the Galactic Bulge seen through micro-lensing events
EPJ Web of Conferences, 2012 Galactic bulges are central to understanding galaxy formation and evolution. Here we report on recent studies using micro-lensing events to obtain spectra of high resolution and moderately high signal-to-noise ratios of dwarf stars in the Galactic bulge.

Bose-Einstein Condensate Dark Matter Halos Confronted with Galactic Rotation Curves
Advances in High Energy Physics, 2017 We present a comparative confrontation of both the Bose-Einstein Condensate (BEC) and the Navarro-Frenk-White (NFW) dark halo models with galactic rotation curves.

Has the Palomar 14 Globular Cluster Been Captured by the Milky Way?
The Astrophysical JournalWe examine a new scenario to model the outer halo globular cluster (GC) Palomar 14 (Pal 14) over its lifetime by performing a comprehensive set of direct N -body calculations.

Star Forming Dwarf Galaxies [PDF]
, 2011 Star forming dwarf galaxies (SFDGs) have a high gas content and low metallicities, reminiscent of the basic entities in hierarchical galaxy formation scenarios. In the young universe they probably also played a major role in the cosmic reionization. Their abundant presence in the local volume and their youthful character make them ideal objects for ...

Hedgehog: An Isolated Quiescent Dwarf Galaxy at 2.4 Mpc
The Astrophysical Journal LettersIt is well known that almost all isolated dwarf galaxies are actively forming stars. We report the discovery of dw1322m2053 (nicknamed Hedgehog), an isolated quiescent dwarf galaxy at a distance of 2.40 ± 0.15 Mpc with a stellar mass of M _⋆ ≈ 10 ^5.8 M ...

An Analytical Galactic Chemical Evolution Model with Gas Inflow and a Terminal Wind
The Astrophysical JournalWe present a new analytical galactic chemical evolution (GCE) model with gas inflow, internally caused outflow, and extra gas loss after a period of time. The latter mimics the ram pressure stripping of a dwarf satellite galaxy near the pericenter of its
