Growth of Aromatic Hydrocarbon Dust Particles in the Extremely Metal-poor Galaxy Sextans A
Elizabeth J. Tarantino, Julia Roman-Duval, Karin M. Sandstrom +17
The mid-infrared spectrum of star-forming, high metallicity galaxies is dominated by emission features from aromatic and aliphatic bonds in small carbonaceous dust grains, often re…
Chandra Large Project Observations of the Supernova Remnant N132D: Measuring the Expansion of the Forward Shock
Xi Long, Paul P. Plucinsky, Terrance J. Gaetz +15
We present results from the Chandra X-ray Observatory Large Project (878 ks in 28 observations) of the Large Magellanic Cloud supernova remnant N132D. We measure the expansion of t…
The Hubble Arp Galaxy Survey
Julianne J. Dalcanton, Meredith J. Durbin, Benjamin F. Williams
The typical galaxy in the local universe is expected to be in a self-regulated quasi-equilibrium, displaying a settled morphology that falls within the Hubble Sequence. The Arp and…
Detection of Deuterated Hydrocarbon Nanoparticles in the Whirlpool Galaxy, M51
B. T. Draine, Karin Sandstrom, Daniel A. Dale +29
Deuteration of hydrocarbon material, including polycyclic aromatic hydrocarbons (PAHs), has been proposed to account for the low gas-phase abundances of D in the interstellar mediu…
Strikingly high fraction of fast rotators in Magellanic Cloud star clusters
Greta Ettorre, Alessandro Mazzi, Leo Girardi +14
There has been growing evidence that the rich star clusters in the Magellanic Clouds contain significant fractions of rapidly rotating stars. In this work, we aim to constrain thes…
The Local Ultraviolet to Infrared Treasury II. Refining Star Formation Histories of Ten Metal-Poor Dwarf Galaxies with Simultaneous UV-Optical Two-CMD Fitting
Yumi Choi, Karoline M. Gilbert, Benjamin F. Williams +10
We present the star formation histories (SFHs) of ten metal-poor (<12% Zsun), star-forming dwarf galaxies from the Local Ultraviolet to Infrared Treasury (LUVIT) survey. The derive…
Evidence for a hot galactic halo around the Andromeda Galaxy using fast radio bursts along two sightlines
Reshma Anna-Thomas, Casey J. Law, Eric W. Koch +17
Fast Radio Bursts (FRBs) are millisecond-duration radio transients that serve as unique probes of ionized extragalactic matter. We report the discovery and localization of two FRBs…
Stellar Ages: A Code to Infer Properties of Stellar Populations
Joseph J. Guzman, Jeremiah W. Murphy, Andres F. Barrientos +2
We present a novel statistical algorithm, Stellar Ages, which currently infers the age, metallicity, and extinction posterior distributions of stellar populations from their magnit…
A Catalog of Stellar and Dust Properties for 500,000 Stars in the Southwest Bar of the Small Magellanic Cloud
Petia Yanchulova Merica-Jones, Karl Gordon, Karin Sandstrom +8
We present a catalog of individual stellar and dust extinction properties along close to 500,000 sight lines in the southwest bar of the Small Magellanic Cloud (SMC). The catalog i…
The Progenitor Systems of Classical Novae in M31
C. S. Abelson, Carles Badenes, Laura Chomiuk +4
We present the first characterization of the statistical relationship between a large sample of novae in M31 and their progenitor stellar populations in the form of a delay time di…
