The Curious Case of Centaurus A: On the Subject of the Quenched satellites
Sachi Weerasooriya, Mia Sauda Bovill, Matthew A. Taylor +6
The satellite system of Centaurus A presents a curious cosmological puzzle: while the global population is consistent with theoretical expectations, its inner regions (d<150 kpc) e…
On the Origins of "Hostless'' Supernovae: Testing the Faint-end Galaxy Luminosity Function and Supernova Progenitors with Events in Dwarf Galaxies
Louis-Gregory Strolger, Mia Sauda Bovill, Eric Perlman +3
We present arguments on the likely origins of supernovae without associated host galaxies from open field, non-clustered, environments. We show why it is unlikely these ``hostless'…
Kindling the First Stars II: Dependence of the Predicted PISN Rate on the Pop III Initial Mass Function
Alessa Ibrahim Wiggins, Mia Sauda Bovill, Louis-Gregory Strolger +2
Population III (Pop III) stars formed out of metal free gas in minihalos at . While their ignition ended the Dark Ages and begin enrichment of the IGM, their mass distributio…
A comprehensive model for the formation and evolution of the faintest Milky Way dwarf satellites
Niusha Ahvazi, Andrew Benson, Laura V. Sales +4
In this study, we modify the semi-analytic model Galacticus in order to accurately reproduce the observed properties of dwarf galaxies in the Milky Way. We find that reproducing ob…
Devouring The Centaurus A Satellites: Modeling Dwarf Galaxies with Galacticus
Sachi Weerasooriya, Mia Sauda Bovill, Matthew A. Taylor +2
For the first time, systematic studies of dwarf galaxies are being conducted throughout the Local Volume, including the dwarf satellites of the nearby giant elliptical galaxy Centa…
Kindling the First Stars: I. Dependence of Detectability of the First Stars with JWST on the Pop III Stellar Masses
Mia Sauda Bovill, Massimo Stiavelli, Alessa Ibrahim Wiggins +2
The first Pop III stars formed out of primordial, metal free gas, in minihalos at z>20, and kickstarted the cosmic processes of reionizaton and enrichment. While these stars are li…
Devouring the Milky Way Satellites: Modeling Dwarf Galaxies with Galacticus
Sachi Weerasooriya, Mia Sauda Bovill, Andrew Benson +2
Dwarf galaxies are ubiquitous throughout the universe and are extremely sensitive to various forms of internal and external feedback. Over the last two decades, the census of dwarf…
A Collection of New Dwarf Galaxies in NGC5128's Western Halo
Matthew A. Taylor, Paul Eigenthaler, Thomas H. Puzia +5
We report the photometric properties of 16 dwarf galaxies, 15 of which are newly identified, in the Western halo of the nearby giant elliptical galaxy NGC5128. All candidates are f…
The Survey of Centaurus A's Baryonic Structures (SCABS). I. Survey Description and Initial Source Catalogues
Matthew A. Taylor, Roberto P. Muñoz, Thomas H. Puzia +3
We present new, wide-field, optical () Dark Energy Camera observations covering centred on the nearby giant elliptical galaxy NGC5128 called "The…
The Lost Dwarfs of Centaurus A and the Formation of its Dark Globular Clusters
Mia Sauda Bovill, Thomas H. Puzia, Massimo Ricotti +1
We present theoretical constraints for the formation of the newly discovered dark star clusters (DSCs) with high mass-to-light (M/L) ratios, from Taylor et al (2015). These compact…
The Survey of Centaurus A's Baryonic Structures (SCABS). II. The Extended Globular Cluster System of NGC5128 and its Nearby Environment
Matthew A. Taylor, Thomas H. Puzia, Roberto P. Muñoz +5
Wide-field Dark Energy Camera observations centred on the giant elliptical galaxy NGC5128 covering are used to compile a new catalogue of glob…
