The Quest for the Missing Dust: II -- Two Orders of Magnitude of Evolution in the Dust-to-Gas Ratio Resolved Within Local Group Galaxies

Christopher J. R. Clark, Julia C. Roman-Duval, Karl D. Gordon +3

We explore evolution in the dust-to-gas ratio with density within four well-resolved Local Group galaxies - the LMC, SMC, M31, and M33. We do this using new maps,…

METAL: The Metal Evolution, Transport, and Abundance in the Large Magellanic Cloud Hubble program. II. Variations of interstellar depletions and dust-to-gas ratio within the LMC

Julia Roman-Duval, Edward B. Jenkins, Kirill Tchernyshyov +9

A key component of the baryon cycle in galaxies is the depletion of metals from the gas to the dust phase in the neutral ISM. The METAL (Metal Evolution, Transport and Abundance in…

Towards Space-like Photometric Precision from the Ground with Beam-Shaping Diffusers

Gudmundur Stefansson, Suvrath Mahadevan, Leslie Hebb +21

We demonstrate a path to hitherto unachievable differential photometric precisions from the ground, both in the optical and near-infrared (NIR), using custom-fabricated beam-shapin…

On the Classification of UGC1382 as a Giant Low Surface Brightness Galaxy

Lea M. Z. Hagen, Mark Seibert, Alex Hagen +6

We provide evidence that UGC1382, long believed to be a passive elliptical galaxy, is actually a giant low surface brightness (GLSB) galaxy which rivals the archetypical GLSB Malin…

The Evolution of the Far-UV Luminosity Function and Star Formation Rate Density of the Chandra Deep Field South from z=0.2-1.2 with Swift/UVOT

Lea M. Z. Hagen, Erik A. Hoversten, Caryl Gronwall +4

We use deep Swift UV/Optical Telescope (UVOT) near-ultraviolet (1600A to 4000A) imaging of the Chandra Deep Field South to measure the rest-frame far-UV (FUV; 1500A) luminosity fun…
