Why do galaxies stop forming stars? I. The passive fraction - black hole mass relation for central galaxies
Asa F. L. Bluck, Sara L. Ellison, David R. Patton +5
We derive the dependence of the fraction of passive central galaxies on the mass of their supermassive black holes for a sample of over 400,000 SDSS galaxies at z < 0.2. Our large…
The first carbon-enhanced metal-poor star found in the Sculptor dwarf spheroidal
Asa Skuladottir, Eline Tolstoy, Stefania Salvadori +4
The origin of carbon-enhanced metal-poor (CEMP) stars and their possible connection with the chemical elements produced by the first stellar generation is still highly debated. In…
Chemical enrichment in very low-metallicity environments: Bootes I
Donatella Romano, Michele Bellazzini, Else Starkenburg +1
We present different chemical evolution models for the ultrafaint dwarf galaxy Bootes I. We either assume that the galaxy accretes its mass through smooth infall of gas of primordi…
Galactic Tides and the Shape and Orientation of Dwarf Galaxy Satellites
Christopher Barber, Else Starkenburg, Julio F. Navarro +1
We use cosmological N-body simulations from the Aquarius Project to study the tidal effects of a dark matter halo on the shape and orientation of its substructure. Although tides a…
VLT/FLAMES spectroscopy of red giant branch stars in the Fornax dwarf spheroidal galaxy
B. Lemasle, T. de Boer, V. Hill +13
Fornax is one of the most massive dwarf spheroidal galaxies in the Local Group. The Fornax field star population is dominated by intermediate age stars but star formation was going…
Binarity in Carbon-Enhanced Metal-Poor stars
Else Starkenburg, Matthew D. Shetrone, Alan W. McConnachie +1
A substantial fraction of the lowest metallicity stars show very high enhancements in carbon. It is debated whether these enhancements reflect the stars' birth composition, or if t…
