A "Light," Centrally-Concentrated Milky Way Halo?
Valery Rashkov, Annalisa Pillepich, Alis J. Deason +4
We discuss a novel approach to "weighing" the Milky Way dark matter halo, one that combines the latest samples of halo stars selected from the Sloan Digital Sky Survey (SDSS) with…
Pseudobulge Formation as a Dynamical Rather than a Secular Process
Javiera Guedes, Lucio Mayer, Marcella Carollo +1
We investigate the formation and evolution of the pseudobulge in "Eris", a high-resolution N-body + smoothed particle hydrodynamics (SPH) cosmological simulation that successfully…
The circumgalactic medium of massive galaxies at z~3: a test for stellar feedback, galactic outflows, and cold streams
Sijing Shen, Piero Madau, Javiera Guedes +3
We present new results on the kinematics, thermal and ionization state, and spatial distribution of metal-enriched gas in the circumgalactic medium (CGM) of massive galaxies at red…
The origin of metals in the circum-galactic medium of massive galaxies at z=3
Sijing Shen, Piero Madau, Anthony Aguirre +3
We present a detailed study of the metal-enriched circum-galactic medium of a massive galaxy at z=3 using "ErisMC", a new cosmological hydrodynamic "zoom-in" simulations of a disk…
Forming Realistic Late-Type Spirals in a LCDM Universe: The Eris Simulation
Javiera Guedes, Simone Callegari, Piero Madau +1
Simulations of the formation of late-type spiral galaxies in a cold dark matter LCDM universe have traditionally failed to yield realistic candidates. Here we report a new cosmolog…
