A Gaia-aided view of the properties of Local Group dwarf galaxies
The Local Group hosts almost 100 dwarf galaxies, i.e. galaxies with stellar masses at least one order of magnitude lower than that of the Milky Way.
As the smallest galaxies and the most dark matter dominated ones that we can observe, these nearby dwarf galaxies are widely considered
as precious systems to shed light on the...

Science with the Stratospheric Observatory For Infrared Astronomy (SOFIA)
The Stratospheric Observatory For Infrared Astronomy (SOFIA) in an US/German flying infrared astronomical observatory.
SOFIA is an 80/20 project of NASA and the German Aerospace Center (DLR).
SOFIA is based on a modified Boeing 747SP aircraft carrying a reflecting telescope with a diameter of 2.7m (effective 2.5m).

Mass spectrum of Pop III stars
Pop III stars are expected to form in pristine dark matter halos of a few times 10^5-10^7 solar masses halos at z > 10. Their mass spectrum remains unknown so-far due to the lack of direct observational constraints. In this talk I will present results from 3D radiation hydrodynamics cosmological simulations and show that massive stars up to hundred thousand solar...
