The Baryon Cycle of Dwarf Galaxies: Dark, Bursty, Gas-Rich Polluters
Sijing Shen, Piero Madau, Charlie Conroy +2
We present results from a fully cosmological, very high-resolution, LCDM "zoom-in" simulation of a group of seven field dwarf galaxies with present-day virial masses in the range M…
The MaGICC Baryon Cycle: The Enrichment History of Simulated Disc Galaxies
C. B. Brook, G. Stinson, B. K. Gibson +4
Using cosmological galaxy formation simulations from the MaGICC project, spanning more than three magnitudes in stellar mass (~10^7-3x10^{10} Msun), we trace the baryonic cycle of…
The effect of models of the interstellar media on the central mass distribution of galaxies
Charlotte Christensen, Fabio Governato, Thomas Quinn +5
We compare the central mass distribution of galaxies simulated with three different models of the interstellar medium (ISM) with increasing complexity: primordial (H+He) cooling do…
Reproducing the Stellar Mass/Halo Mass Relation in Simulated LCDM Galaxies: Theory vs Observational Estimates
Ferah Munshi, F. Governato, A. M. Brooks +6
We examine the present-day total stellar-to-halo mass (SHM) ratio as a function of halo mass for a new sample of simulated field galaxies using fully cosmological, LCDM, high resol…
Baryons Matter: Why Luminous Satellite Galaxies Have Reduced Central Masses
Adi Zolotov, Alyson M. Brooks, Beth Willman +7
Using high resolution cosmological hydrodynamical simulations of Milky Way-massed disk galaxies, we demonstrate that supernovae feedback and tidal stripping lower the central masse…
Implementing Molecular Hydrogen in Hydrodynamic Simulations of Galaxy Formation
Charlotte Christensen, Thomas Quinn, Fabio Governato +3
Motivated by the observed connection between molecular hydrogen (H2) and star formation, we present a method for tracking the non-equilibrium abundance and cooling processes of H2…
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…
Cuspy No More: How Outflows Affect the Central Dark Matter and Baryon Distribution in Lambda CDM Galaxies
F. Governato, A. Zolotov, A. Pontzen +6
We examine the evolution of the inner dark matter (DM) and baryonic density profile of a new sample of simulated field galaxies using fully cosmological, Lambda CDM, high resolutio…
MAGICC haloes: confronting simulations with observations of the circumgalactic medium at z=0
Greg Stinson, Chris Brook, J. Xavier Prochaska +8
We explore the circumgalactic medium (CGM) of two simulated star-forming galaxies with luminosities L ~ 0.1 and 1 L* generated using the smooth particle hydrodynamic code GASOLINE.…
Halo expansion in cosmological hydro simulations: towards a baryonic solution of the cusp/core problem in massive spirals
Andrea V. Maccio', Greg Stinson, Chris B. Brook +5
A clear prediction of the Cold Dark Matter model is the existence of cuspy dark matter halo density profiles on all mass scales. This is not in agreement with the observed rotation…
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…
The First Massive Black Hole Seeds and Their Hosts
Jillian Bellovary, Marta Volonteri, Fabio Governato +3
We investigate the formation of the first massive black holes in high redshift galaxies, with the goal of providing insights to which galaxies do or do not host massive black holes…
Wandering Black Holes in Bright Disk Galaxy Halos
Jillian Bellovary, Fabio Governato, Tom Quinn +3
We perform SPH+N-body cosmological simulations of massive disk galaxies, including a formalism for black hole seed formation and growth, and find that satellite galaxies containing…
Cosmological Galaxy Formation Simulations Using SPH
G. Stinson, J. Bailin, H. Couchman +4
We present the McMaster Unbiased Galaxy Simulations (MUGS), the first 9 galaxies of an unbiased selection ranging in total mass from 5 M to 2…
Consequences of cosmic microwave background-regulated star formation
Jeremy Bailin, Greg Stinson, Hugh Couchman +3
It has been hypothesized that the cosmic microwave background (CMB) provides a temperature floor for collapsing protostars that can regulate the process of star formation and resul…
The Enrichment of the Intergalactic Medium with Adiabatic Feedback I: Metal Cooling and Metal Diffusion
Sijing Shen, James Wadsley, Gregory Stinson
A study of the IGM metal enrichment using a series of SPH simulations is presented, employing metal cooling and turbulent diffusion of metals and thermal energy. An adiabatic feedb…
