The Impact of Stellar Migration on Disk Outskirts
Victor P. Debattista, Rok Roskar, Sarah R. Loebman
Stellar migration, whether due to trapping by transient spirals (churning), or to scattering by non-axisymmetric perturbations, has been proposed to explain the presence of stars i…
Imprints of radial migration on the Milky Way's metallicity distribution functions
Sarah R. Loebman, Victor P. Debattista, David L. Nidever +5
Recent analysis of the SDSS-III/APOGEE Data Release 12 stellar catalogue has revealed that the Milky Way's metallicity distribution function (MDF) changes shape as a function of ra…
Internal Alignments of Red Versus Blue Discs in Dark Matter Halos
Victor P. Debattista, Frank C. van den Bosch, Rok Roskar +3
Large surveys have shown that red galaxies are preferentially aligned with their halos while blue galaxies have a more isotropic distribution. Since halos generally align with thei…
Direct formation of supermassive black holes in metal-enriched gas at the heart of high-redshift galaxy mergers
Lucio Mayer, Davide Fiacconi, Silvia Bonoli +4
We present novel 3D multi-scale SPH simulations of gas-rich galaxy mergers between the most massive galaxies at , designed to scrutinize the direct collapse formatio…
The formation of stellar nuclear discs in bar-induced gas inflows
David R. Cole, Victor P. Debattista, Peter Erwin +2
The role of gas in the mass assembly at the nuclei of galaxies is still subject to some uncertainty. Stellar nuclear discs bridge the gap between the large-scale galaxy and the cen…
The Milky Way Tomography with SDSS. V. Mapping the Dark Matter Halo
Sarah R. Loebman, Zeljko Ivezic, Thomas R. Quinn +6
We present robust constraints from the Sloan Digital Sky Survey (SDSS) on the shape and distribution of the dark matter halo within the Milky Way (MW). Using the number density dis…
