Simulating dust grain-radiation coupling on a moving mesh
Ryan McKinnon, Rahul Kannan, Mark Vogelsberger +3
We present a model for the interaction between dust and radiation fields in the radiation hydrodynamic code AREPO-RT, which solves the moment-based radiative transfer equations on…
Dust in and around galaxies: dust in cluster environments and its impact on gas cooling
Mark Vogelsberger, Ryan McKinnon, Stephanie O'Neil +3
Simulating the dust content of galaxies and their surrounding gas is challenging due to the wide range of physical processes affecting the dust evolution. Here we present cosmologi…
Simulating galactic dust grain evolution on a moving mesh
Ryan McKinnon, Mark Vogelsberger, Paul Torrey +2
Interstellar dust is an important component of the galactic ecosystem, playing a key role in multiple galaxy formation processes. We present a novel numerical framework for the dyn…
AREPO-RT: Radiation hydrodynamics on a moving mesh
Rahul Kannan, Mark Vogelsberger, Federico Marinacci +3
We introduce AREPO-RT, a novel radiation hydrodynamic (RHD) solver for the unstructured moving-mesh code AREPO. Our method solves the moment-based radiative transfer equations usin…
Similar star formation rate and metallicity evolution timescales drive the fundamental metallicity relation
Paul Torrey, Mark Vogelsberger, Lars Hernquist +10
The fundamental metallicity relation (FMR) is a postulated correlation between galaxy stellar mass, star formation rate (SFR), and gas-phase metallicity. At its core, this relation…
LSQ14efd: observations of the cooling of a shock break-out event in a type Ic Supernova
C. Barbarino, M. T. Botticella, M. Dall'Ora +29
We present the photometric and spectroscopic evolution of the type Ic supernova LSQ14efd, discovered by the La Silla QUEST survey and followed by PESSTO. LSQ14efd was discovered fe…
Simulating the dust content of galaxies: successes and failures
Ryan McKinnon, Paul Torrey, Mark Vogelsberger +2
We present full volume cosmological simulations using the moving-mesh code AREPO to study the coevolution of dust and galaxies. We extend the dust model in AREPO to include thermal…
First Results from the La Silla-QUEST Supernova Survey and the Carnegie Supernova Project
E. S. Walker, C. Baltay, A. Campillay +20
The LaSilla/QUEST Variability Survey (LSQ) and the Carnegie Supernova Project (CSP II) are collaborating to discover and obtain photometric light curves for a large sample of low r…
LSQ13fn: A type II-Plateau supernova with a possibly low metallicity progenitor that breaks the standardised candle relation
J. Polshaw, R. Kotak, L. Dessart +20
We present optical imaging and spectroscopy of supernova (SN) LSQ13fn, a type II supernova with several hitherto-unseen properties. Although it initially showed strong symmetric sp…
An analysis of the evolving comoving number density of galaxies in hydrodynamical simulations
Paul Torrey, Sarah Wellons, Francisco Machado +9
The cumulative comoving number-density of galaxies as a function of stellar mass or central velocity dispersion is commonly used to link galaxy populations across different epochs.…
LSQ14bdq: A Type Ic super-luminous supernova with a double-peaked light curve
M. Nicholl, S. J. Smartt, A. Jerkstrand +28
We present data for LSQ14bdq, a hydrogen-poor super-luminous supernova (SLSN) discovered by the La Silla QUEST survey and classified by the Public ESO Spectroscopic Survey of Trans…
Dust Formation in Milky Way-like Galaxies
Ryan McKinnon, Paul Torrey, Mark Vogelsberger
We introduce a dust model for cosmological simulations implemented in the moving-mesh code AREPO and present a suite of cosmological hydrodynamical zoom-in simulations to study dus…
On the diversity of super-luminous supernovae: ejected mass as the dominant factor
M. Nicholl, S. J. Smartt, A. Jerkstrand +37
We assemble a sample of 24 hydrogen-poor super-luminous supernovae (SLSNe). Parameterizing the light curve shape through rise and decline timescales shows that the two are highly c…

We present optical observations of the peculiar stripped-envelope supernovae (SNe) LSQ12btw and LSQ13ccw discovered by the La Silla-QUEST survey. LSQ12btw reaches an absolute peak…
A comparative study of Type II-P and II-L supernova rise times as exemplified by the case of LSQ13cuw
