Ground-based Paα Narrow-band Imaging of Local Luminous Infrared Galaxies. I. Star Formation Rates and Surface Densities
Tamura, Yoichi; Kohno, Kotaro; Tanabé, Toshihiko +33 more
Luminous infrared galaxies (LIRGs) are enshrouded by a large amount of dust produced by their active star formation, and it is difficult to measure their activity in optical wavelengths. We have carried out Paα narrow-band imaging observations of 38 nearby star forming galaxies including 33 LIRGs listed in the IRAS Revised Bright Galaxy Sample cat…
Chemical Abundances and Dust in the Halo Planetary Nebula K648 in M15: Its Origin and Evolution Based on an Analysis of Multiwavelength Data
Otsuka, Masaaki; Hyung, Siek; Tajitsu, Akito
We report on an investigation of the extremely metal-poor and C-rich planetary nebula (PN) K648 in M15 using the UV to far-infrared data obtained using Subaru, the Hubble Space Telescope, the Far Ultraviolet Spectroscopic Explorer, Spitzer, and Herschel. We determined the nebular abundances of 10 elements. The enhancement of F ([F/H] = +0.96) is c…
The WISE Light Curves of Polars
Harrison, Thomas E.; Campbell, Ryan K.
We have extracted the WISE (Wide-field Infrared Survey Explorer) single-exposure data for a sample of 72 polars, which are highly magnetic cataclysmic variables (CVs). We combine these data with both published and unpublished optical and infrared data to explore the origins of the large amplitude variations seen in these systems. In nearly every c…
A GALEX-based Search for the Sparse Young Stellar Population in the Taurus-Aurigae Star Forming Region
Gómez de Castro, Ana I.; López-Martínez, Fatima; Sánchez, Néstor +5 more
In this work, we identify 63 bona fide new candidates to T Tauri stars (TTSs) in the Taurus-Auriga region, using its ultraviolet excess as our baseline. The initial data set was defined from the GALEX all sky survey (AIS). The GALEX satellite obtained images in the near-ultraviolet (NUV) and far-ultraviolet (FUV) bands where TTSs show a prominent …
Gemini Frontier Fields: Wide-field Adaptive Optics Ks-band Imaging of the Galaxy Clusters MACS J0416.1-2403 and Abell 2744
Schirmer, M.; Winge, C.; Neichel, B. +4 more
We have observed two of the six Frontier Fields galaxy clusters, MACS J0416.1-2403 and Abell 2744, using the Gemini Multi-Conjugate Adaptive Optics System (GeMS) and the Gemini South Adaptive Optics Imager (GSAOI). With 0.″ 08-0.″ 10 FWHM our data are nearly diffraction-limited over a 100\prime\prime × 100\prime\prime wide ar…
The SWIFT AGN and Cluster Survey. I. Number Counts of AGNs and Galaxy Clusters
Bregman, Joel N.; Kochanek, Christopher S.; Dai, Xinyu +2 more
The Swift active galactic nucleus (AGN) and Cluster Survey (SACS) uses 125 deg2 of Swift X-ray Telescope serendipitous fields with variable depths surrounding γ-ray bursts to provide a medium depth (4× {{10}-15} erg cm-2 s-1) and area survey filling the gap between deep, narrow Chandra/XMM-Newton surveys…
A Deep Near-infrared Survey toward the Aquila Molecular Cloud. I. Molecular Hydrogen Outflows
Fang, Min; Wang, Hongchi; Wang, Min +4 more
We have performed an unbiased, deep near-infrared survey toward the Aquila molecular cloud with a sky coverage of ∼1 deg2. We identified 45 molecular hydrogen emission-line objects (MHOs), of which only 11 were previously known. Using the Spitzer archival data, we also identified 802 young stellar objects (YSOs) in this region. Based on…
The Panchromatic STARBurst IRregular Dwarf Survey (STARBIRDS): Observations and Data Archive
McQuinn, Kristen B. W.; Skillman, Evan D.; Mitchell, Noah P.
Understanding star formation in resolved low mass systems requires the integration of information obtained from observations at different wavelengths. We have combined new and archival multi-wavelength observations on a set of 20 nearby starburst and post-starburst dwarf galaxies to create a data archive of calibrated, homogeneously reduced images…
A Deep XMM-Newton Survey of M33: Point-source Catalog, Source Detection, and Characterization of Overlapping Fields
Williams, Benjamin F.; Blair, William P.; Haberl, Frank +9 more
We have obtained a deep 8 field XMM-Newton mosaic of M33 covering the galaxy out to the D25 isophote and beyond to a limiting 0.2-4.5 keV unabsorbed flux of 5 × 10-16 erg cm-2 s-1 (L \gt 4 × 1034 erg s-1 at the distance of M33). These data allow complete coverage of the galaxy with …
The Swift X-Ray Telescope Cluster Survey. III. Cluster Catalog from 2005-2012 Archival Data
Giavalisco, Mauro; Rosati, Piero; Tozzi, Paolo +6 more
We present the Swift X-ray Cluster Survey (SWXCS) catalog obtained using archival data from the X-ray telescope (XRT) on board the Swift satellite acquired from 2005 February to 2012 November, extending the first release of the SWXCS. The catalog provides positions, soft fluxes, and, when possible, optical counterparts for a flux-limited sample of…
