The AGORA High-Resolution Galaxy Simulations Comparison Project
Ji-hoon Kim, Tom Abel, Oscar Agertz +43
We introduce the AGORA project, a comprehensive numerical study of well-resolved galaxies within the LCDM cosmology. Cosmological hydrodynamic simulations with force resolutions of…
Recovering the observed B/C ratio in a dynamic spiral-armed cosmic ray model
David Benyamin, Ehud Nakar, Tsvi Piran +1
We develop a fully three dimensional numerical code describing the diffusion of cosmic rays in the Milky Way. It includes the nuclear spallation chain up to Oxygen, and allows the…
CANDELS: The correlation between galaxy morphology and star formation activity at z~2
Bomee Lee, Mauro Giavalisco, Christina C. Williams +13
We discuss the state of the assembly of the Hubble Sequence in the mix of bright galaxies at redshift 1.4< z \le 2.5 with a large sample of 1,671 galaxies down to H_{AB}~26, select…
A sub-parsec resolution simulation of the Milky Way: Global structure of the ISM and properties of molecular clouds
F. Renaud, F. Bournaud, E. Emsellem +9
We present a self-consistent hydrodynamical simulation of a Milky Way-like galaxy, at the resolution of 0.05 pc. The model includes star formation and a new implementation of stell…
The Velocity Distribution of Hypervelocity Stars
Elena M. Rossi, Shiho Kobayashi, Re'em Sari
We consider the process of stellar binaries tidally disrupted by a supermassive black hole. For highly eccentric orbits, as one star is ejected from the three-body system, the comp…
Disk Assembly and the M_BH-sigma Relation of Supermassive Black Holes
Victor P. Debattista, Stelios Kazantzidis, Frank C. van den Bosch
Recent Hubble Space Telescope (HST) observations have revealed that a majority of active galactic nuclei (AGN) at z ~ 1-3 are resident in isolated disk galaxies, contrary to the us…
