High-excitation OH and H_2O lines in Markarian 231: the molecular signatures of compact far-infrared continuum sources
Eduardo González-Alfonso, Howard A. Smith, Matthew L. N. Ashby +3
The ISO/LWS far-infrared spectrum of the ultraluminous galaxy Mkn 231 shows OH and H_2O lines in absorption from energy levels up to 300 K above the ground state, and emission in t…

Using full-disk observations obtained with the Michelson Doppler Imager (MDI) on board the Solar and Heliospheric Observatory (SOHO) spacecraft, we present variations of the solar…
Detection of atmospheric haze on an extrasolar planet: The 0.55 - 1.05 micron transmission spectrum of HD189733b with the Hubble Space Telescope
F. Pont, H. Knutson, R. L. Gilliland +2
The nearby transiting planet HD 189733b was observed during three transits with the ACS camera of the Hubble Space Telescope in spectroscopic mode. The resulting time series of 675…
The LMXB Population of NGC 3379

Presented here are the highlights from the deep Chandra observation of the elliptical galaxy NGC 3379. From the multi-epoch observation of this galaxy, 132 discrete X-ray sources h…
Where Centaurus A gets its X-ray knottiness
D. M. Worrall, M. Birkinshaw, R. P. Kraft +15
We report an X-ray spectral study of the transverse structure of the Centaurus A jet using new data from the Chandra Cen A Very Large Project. We find that the spectrum steepens wi…
Mesolensing Explorations of Nearby Masses: From Planets to Black Holes
R. Di Stefano
Nearby masses can have a high probability of lensing stars in a distant background field. High-probability lensing, or mesolensing, can therefore be used to dramatically increase o…
The Spitzer Gould Belt Survey of Large Nearby Interstellar Clouds: Discovery of a Dense Embedded Cluster in the Serpens-Aquila Rift
R. A. Gutermuth, T. L. Bourke, L. E. Allen +12
We report the discovery of a nearby, embedded cluster of young stellar objects, associated filamentary infrared dark cloud, and 4.5 micron shock emission knots from outflows detect…
Variable Low-Mass X-ray Binaries in Early-Type Galaxies
Gregory R. Sivakoff, Andrés Jordán, Adrienne M. Juett +2
As the Chandra X-ray Observatory mission matures, increasing numbers of nearby galaxies are being observed multiple times, sampling the variability of extragalactic X-ray binaries…
X-ray and IR Point Source Identification and Characteristics in the Embedded, Massive Star-Forming Region RCW 108
Scott J. Wolk, Bradley D. Spitzbart, Tyler L. Bourke +3
We report on the results of an approximately 90 ks Chandra observation of a complex region that hosts multiple sites of recent and active star formation in ARA OB1a. The field is c…
CaII Infrared triplet line models in Classical T Tauri stars
R. Azevedo, N. Calvet, L. Hartmann +3
We study the formation of the calcium II infrared triplet lines 8498Å, 8542Åand 8662Å, in the accreting magnetospheric flows of Classical T Tauri stars (CTTS), and present a grid o…
Identification of Spinning Dust in Halpha-Correlated Microwave Emission
Gregory Dobler, Douglas P. Finkbeiner
CMB experiments commonly use maps of Halpha intensity as a spatial template for Galactic free-free emission, assuming a power law I_nu \propto nu^-0.15 for the spectrum. Any depart…
X-Ray Flaring on the dMe Star, Ross 154
B. J. Wargelin, V. L. Kashyap, J. J. Drake +2
We present results from two Chandra imaging observations of Ross 154, a nearby flaring M dwarf star. During a 61-ks ACIS-S exposure, a very large flare occurred (the equivalent of…
Infrared and X-Ray Evidence for Circumstellar Grain Destruction by the Blast Wave of Supernova 1987A
E. Dwek, R. G. Arendt, P. Bouchet +10
Multiwavelength observations of supernova remnant (SNR) 1987A show that its morphology and luminosity are rapidly changing at X-ray, optical, infrared, and radio wavelengths as the…
Missing Baryons and the Warm-Hot Intergalactic Medium
F. Nicastro, Smita Mathur, Martin Elvis
Stars and gas in galaxies, hot intracluster medium, and intergalactic photo-ionized gas make up at most half of the baryons that are expected to be present in the universe. The maj…
Time-resolved Observation and Control of Superexchange Interactions with Ultracold Atoms in Optical Lattices
S. Trotzky, P. Cheinet, S. Fölling +7
Quantum mechanical superexchange interactions form the basis of quantum magnetism in strongly correlated electronic media. We report on the direct measurement of superexchange inte…
