Getting to know the Stellar Clusters in NGC 1569: Bayesian inference of stellar cluster properties in a dwarf starburst galaxy
Bjarki Björgvinsson, Anna F. McLeod, Bronwyn Reichardt Chu +3
We present a Bayesian analysis of star clusters in the dwarf starburst galaxy NGC 1569 based on high-resolution Hubble Space Telescope imaging combined with integral-field spectros…
The Milky Way Radial Metallicity Gradient as an Equilibrium Phenomenon: Why Old Stars are Metal-Rich
James W. Johnson, David H. Weinberg, Guillermo A. Blanc +12
Metallicities of both gas and stars decline toward large radii in spiral galaxies, a trend known as the radial metallicity gradient. We quantify the evolution of the metallicity gr…
Unveiling the Complex Circumgalactic Medium: A Comparative Study of Merging and Non-Interacting Galaxy Groups
Antonia Fernandez-Figueroa, Glenn G. Kacprzak, Nikole M. Nielsen +5
While most galaxies live in group environments where they undergo an accelerated evolution, the characteristics of their circumgalactic medium (CGM) remain uncertain. We present an…
DUVET: Resolved direct metallicity measurements in the outflow of starburst galaxy NGC 1569
Magdalena J. Hamel-Bravo, Deanne B. Fisher, Danielle Berg +15
We present the results of direct-method metallicity measurements in the disk and outflow of the low-metallicity starburst galaxy NGC 1569. We use Keck Cosmic Web Imager observation…
DUVET: sub-kiloparsec resolved star formation driven outflows in a sample of local starbursting disk galaxies
Bronwyn Reichardt Chu, Deanne B. Fisher, John Chisholm +13
We measure resolved (kiloparsec-scale) outflow properties in a sample of 10 starburst galaxies from the DUVET (Deep near-UV observations of Entrained gas in Turbulent galaxies) sam…
DUVET Survey: Mapping Outflows in the Metal-Poor Starburst Mrk 1486
Daniel K. McPherson, Deanne B. Fisher, Nikole M. Nielsen +11
We present a method to characterize star-formation driven outflows from edge-on galaxies and apply this method to the metal-poor starburst galaxy, Mrk 1486. Our method uses the dis…
