Two Local Volume Dwarf Galaxies Discovered in 21 cm Emission: Pisces A and B
Erik J. Tollerud, Marla C. Geha, Jana Grcevich +2
We report the discovery of two dwarf galaxies, Pisces A and B, from a blind 21 cm HI search. These were the only two galaxies found via optical imaging and spectroscopy of 22 HI cl…
Outflows, Dusty Cores, and a Burst of Star Formation in the North America and Pelican Nebulae
John Bally, Adam Ginsburg, Ron Probst +3
We present observations of near-infrared 2.12 micro-meter molecular hydrogen outflows emerging from 1.1 mm dust continuum clumps in the North America and Pelican Nebula (NAP) compl…
2FGL J1653.6-0159: A New Low in Evaporating Pulsar Binary Periods
Roger W. Romani, Alexei V. Filippenko, S. Bradley Cenko
We have identified an optical binary with orbital period P_b=4488s as the probable counterpart of the Fermi source 2FGL J1653.6-0159. Although pulsations have not yet been detected…
Evidence from the Very Long Baseline Array that J1502SE/SW are Double Hotspots, not a Supermassive Binary Black Hole
J. M. Wrobel, R. C. Walker, H. Fu
SDSS J150243.09+111557.3 is a merging system at z = 0.39 that hosts two confirmed AGN, one unobscured and one dust-obscured, offset by several kiloparsecs. Deane et al. recently re…
Mid-Infrared Spectroscopy of Uranus from the Spitzer Infrared Spectrometer: 1. Determination of the Mean Temperature Structure of the Upper Troposphere and Stratosphere
Glenn S. Orton, Leigh N. Fletcher, Julianne I. Moses +7
On 2007 December 16-17, spectra were acquired of the disk of Uranus by the Spitzer Infrared Spectrometer (IRS) when its equator was close to the sub-earth point. This spectrum prov…
Mid-Infrared Spectroscopy of Uranus from the Spitzer Infrared Spectrometer: 2. Determination of the Mean Composition of the Upper Troposphere and Stratosphere
Glenn S. Orton, J. I. Moses, Leigh N. Fletcher +7
Mid-infrared spectral observations Uranus acquired with the Infrared Spectrometer (IRS) on the Spitzer Space Telescope are used to determine the abundances of C2H2, C2H6, CH3C2H, C…
Absolute Properties of the Eclipsing Binary Star V501 Herculis
Claud H. Sandberg Lacy, Francis C. Fekel
V501 Her is a well detached G3 eclipsing binary star with a period of 8.597687 days for which we have determined very accurate light and radial-velocity curves by using robotic tel…
The Sloan Digital Sky Survey Stripe 82 Imaging Data: Depth-Optimized Co-adds Over 300 Deg^2 in Five Filters
Linhua Jiang, Xiaohui Fan, Fuyan Bian +9
We present and release co-added images of the Sloan Digital Sky Survey (SDSS) Stripe 82. Stripe 82 covers an area of 300 deg^2 on the Celestial Equator, and has been repeatedly sca…
Discovery of a Very Large Structure at Z=3.78
Kyoung-Soo Lee, Arjun Dey, Sungryong Hong +5
We report the discovery of a large-scale structure containing multiple protoclusters at z=3.78 in the Boötes field. The spectroscopic discovery of five galaxies at z=3.783+/-0.002…
Solar System Observations with the James Webb Space Telescope
James Norwood, Heidi Hammel, Stefanie Milam +8
The James Webb Space Telescope will enable a wealth of new scientific investigations in the near- and mid-infrared, with sensitivity and spatial/spectral resolution greatly surpass…
The Spectroscopic Orbits of Five Solar Type, Single Lined Binaries
Francis C. Fekel, Samira Rajabi, Matthew W. Muterspaugh +1
We have determined spectroscopic orbits for five single-lined spectroscopic binaries, HD 100167, HD 135991, HD 140667, HD 158222, HD 217924. Their periods range from 60.6 to 2403 d…
The Ultraviolet Attenuation Law in Backlit Spiral Galaxies
William C. Keel, Anna M. Manning, Benne W. Holwerda +2
(Abridged) The effective extinction law (attenuation behavior) in galaxies in the emitted ultraviolet is well known only for actively star-forming objects and combines effects of t…
