Modeling Mid-Infrared Diagnostics of Obscured Quasars and Starbursts
(IOP Publishing, 2013)
We analyze the link between active galactic nuclei (AGNs) and mid-infrared flux using dust radiative transfer calculations of starbursts realized in hydrodynamical simulations. Focusing on the effects of galaxy dust, we ...
Simulated Galaxy Interactions as Probes of Merger Spectral Energy Distributions
(IOP Publishing, 2014)
We present the first systematic comparison of ultraviolet-millimeter spectral energy distributions (SEDs) of observed and simulated interacting galaxies. Our sample is drawn from the Spitzer Interacting Galaxy Survey and ...
The stellar mass assembly of galaxies in the Illustris simulation: growth by mergers and the spatial distribution of accreted stars
(Oxford University Press (OUP), 2016)
We use the Illustris simulation to study the relative contributions of in situ star formation and stellar accretion to the build-up of galaxies over an unprecedentedly wide range of masses (M* = 109-1012 M⊙), galaxy types, ...
Recoiling black holes: prospects for detection and implications of spin alignment
(Oxford University Press (OUP), 2015)
Supermassive black hole (BH) mergers produce powerful gravitational wave emission. Asymmetry in this emission imparts a recoil kick to the merged BH, which can eject the BH from its host galaxy altogether. Recoiling BHs ...
The total infrared luminosity may significantly overestimate the star formation rate of quenching and recently quenched galaxies
(Oxford University Press (OUP), 2014)
The total infrared (IR) luminosity is very useful for estimating the star formation rate (SFR) of galaxies, but converting the IR luminosity into an SFR relies on assumptions that do not hold for all galaxies. We test the ...
On the assembly of dwarf galaxies in clusters and their efficient formation of globular clusters
(Oxford University Press (OUP), 2015)
Galaxy clusters contain a large population of low-mass dwarf elliptical galaxies whose exact origin is unclear: their colours, structural properties and kinematics differ substantially from those of dwarf irregulars in the ...
