An Infrared Census of DUST in Nearby Galaxies with Spitzer (DUSTiNGS), II. Discovery of Metal-poor Dusty AGB Stars
Martha L. Boyer, K. B. W. McQuinn, P. Barmby +14
The DUSTiNGS survey (DUST in Nearby Galaxies with Spitzer) is a 3.6 and 4.5 micron imaging survey of 50 nearby dwarf galaxies designed to identify dust-producing Asymptotic Giant B…
Dust and Gas in the Magellanic Clouds from the HERITAGE Herschel Key Project. II. Gas-to-Dust Ratio Variations across ISM Phases
Julia Roman-Duval, Karl Gordon, Margaret Meixner +32
The spatial variations of the gas-to-dust ratio (GDR) provide constraints on the chemical evolution and lifecycle of dust in galaxies. We examine the relation between dust and gas…
An Infrared Census of DUST in Nearby Galaxies with Spitzer (DUSTiNGS), I. Overview
Martha L. Boyer, Kristen B. W. McQuinn, Pauline Barmby +13
Nearby resolved dwarf galaxies provide excellent opportunities for studying the dust-producing late stages of stellar evolution over a wide range of metallicity (-2.7 < [Fe/H] < -1…
The influence of supernova remnants on the interstellar medium in the Large Magellanic Cloud seen at 20--600 m wavelengths
Maša Lakićević, Jacco Th. van Loon, Margaret Meixner +20
We present the analysis of supernova remnants (SNRs) in the Large Magellanic Cloud (LMC) and their influence on the environment at far-infrared (FIR) and submillimeter wavelengths.…
The Panchromatic Hubble Andromeda Treasury X. Ultraviolet to Infrared Photometry of 117 Million Equidistant Stars
Benjamin F. Williams, Dustin Lang, Julianne J. Dalcanton +16
We have measured stellar photometry with the Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS) in near ultraviolet (F275W, F336W), optic…
Panchromatic Hubble Andromeda Treasury IX: A Photometric Survey of Planetary Nebulae in M31
Mark J. Veyette, Benjamin F. Williams, Julianne J. Dalcanton +8
We search Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) broadband imaging data from the Panchromatic Hubble Andromeda Treasury (PHAT…
The Panchromatic Hubble Andromeda Treasury. Progression of Large-Scale Star Formation across Space and Time in M31
Dimitrios A. Gouliermis, Lori C. Beerman, Luciana Bianchi +11
We investigate the clustering of early-type stars younger than 300 Myr on galactic scales in M31. Based on the stellar photometric catalogs of the Panchromatic Hubble Andromeda Tre…
Molecular hydrogen emission in the interstellar medium of the Large Magellanic Cloud
Naslim Neelamkodan, Francisca Kemper, Suzanne Madden +20
We present the detection and analysis of molecular hydrogen emission toward ten interstellar regions in the Large Magellanic Cloud. We examined low-resolution infrared spectral map…
Dust and Gas in the Magellanic Clouds from the HERITAGE Herschel Key Project. I. Dust Properties and Insights into the Origin of the Submm Excess Emission
Karl D. Gordon, Julia Roman-Duval, Caroline Bot +33
The dust properties in the Large and Small Magellanic Clouds are studied using the HERITAGE Herschel Key Project photometric data in five bands from 100 to 500 micron. Three simple…
Untangling the Nature of Spatial Variations of Cold Dust Properties in Star Forming Galaxies
Allison Kirkpatrick, Daniela Calzetti, Robert Kennicutt +7
We investigate the far-infrared (IR) dust emission for 20 local star forming galaxies from the Key Insights on Nearby Galaxies: A Far-IR Survey with Herschel (KINGFISH) sample. We…
The Panchromatic Hubble Andromeda Treasury. VII. The Steep Mid-Ultraviolet to Near-Infrared Extinction Curve in the Central 200 pc of the M31 Bulge
Hui Dong, Zhiyuan Li, Q. Daniel Wang +8
We measure the extinction curve in the central 200 pc of M31 at mid-ultraviolet to near-infrared wavelengths (from 1928A to 1.5μm), using Swift/UVOT and HST WFC3/ACS observations i…
Spitzer View of Massive Star Formation in the Tidally Stripped Magellanic Bridge
C. -H. Rosie Chen, Remy Indebetouw, Erik Muller +13
The Magellanic Bridge is the nearest low-metallicity, tidally stripped environment, offering a unique high-resolution view of physical conditions in merging and forming galaxies. I…
