Kepler-7b: A Transiting Planet with Unusually Low Density
David W. Latham, William J. Borucki, David G. Koch +18
We report the discovery and confirmation of Kepler-7b, a transiting planet with unusually low density. The mass is less than half that of Jupiter, Mp = 0.43 Mj, but the radius is f…
Kepler Asteroseismology Program: Introduction and First Results
Ronald L. Gilliland, T. M. Brown, J. Christensen-Dalsgaard +32
Asteroseismology involves probing the interiors of stars and quantifying their global properties, such as radius and age, through observationsof normal modes of oscillation. The te…
WIYN Open Cluster Study. XXXVIII. Stellar Radial Velocities in the Young Open Cluster M35 (NGC 2168)
Aaron M. Geller, Robert D. Mathieu, Ella K. Braden +3
We present 5201 radial-velocity measurements of 1144 stars, as part of an ongoing study of the young (150 Myr) open cluster M35 (NGC 2168). We have observed M35 since 1997, using t…
New candidate Planetary Nebulae in the IPHAS survey: the case of PNe with ISM interaction
Laurence Sabin, Albert A. Zijlstra, Christopher Wareing +5
We present the results of the search for candidate Planetary Nebulae interacting with the interstellar medium (PN-ISM) in the framework of the INT Photometric H Survey (IPHAS) a…
Detection of solar-like oscillations from Kepler photometry of the open cluster NGC 6819
Dennis Stello, Sarbani Basu, Hans Bruntt +49
Asteroseismology of stars in clusters has been a long-sought goal because the assumption of a common age, distance and initial chemical composition allows strong tests of the theor…
Unveiling cosmic X-ray/gamma-ray sources from their scattering screen
Jonathan E. Grindlay
This Commentary discusses the widespread impact of the milestone 1980 paper by Sunyaev and Titarchuk on Comptonization and points out a new possible application to the temporal bro…
Measuring the Accreting Stellar and Intermediate Mass Black Hole Populations in the Galaxy and Local Group
Jonathan Grindlay, Didier Barret, Tomaso Belloni +23
The population of stellar black holes (SBHs) in the Galaxy and galaxies generally is poorly known in both number and distribution. SBHs are the fossil record of the massive stars i…
Including All the Lines
Robert L. Kurucz
I present a progress report on including all the lines in the linelists, including all the lines in the opacities, including all the lines in the model atmosphere and spectrum synt…
An Efficient Approximation of the Coronal Heating Rate for Use in Global Sun-Heliosphere Simulations
Steven R. Cranmer
The origins of the hot solar corona and the supersonically expanding solar wind are still the subject of debate. A key obstacle in the way of producing realistic simulations of the…
A Deep Chandra Observation of the Oxygen-Rich Supernova Remnant 0540-69.3 in the Large Magellanic Cloud
Sangwook Park, John P. Highes, Patrick O. Slane +2
Using our deep ~120 ks Chandra observation, we report on the results from our spatially-resolved X-ray spectral analysis of the "oxygen-rich" supernova remnant (SNR) 0540-69.3 in t…
PKS 2005-489 at VHE: Four Years of Monitoring with HESS and Simultaneous Multi-wavelength Observations
The HESS Collaboration, F. Acero
VHE observations of PKS 2005-489 were made with HESS from 2004 through 2007, together with three simultaneous multi-wavelength campaigns performed with XMM-Newton and RXTE in 2004…
Linking dwarf galaxies to halo building blocks with the most metal-poor star in Sculptor
Anna Frebel, Evan Kirby, Joshua D. Simon
Current cosmological models indicate that the Milky Way's stellar halo was assembled from many smaller systems. Based on the apparent absence of the most metal-poor stars in presen…
Deep Chandra Observations of the Crab-like Pulsar Wind Nebula G54.1+0.3 and Spitzer Spectroscopy of the Associated Infrared Shell
Tea Temim, Patrick Slane, Stephen P. Reynolds +2
G54.1+0.3 is a young pulsar wind nebula (PWN), closely resembling the Crab, for which no thermal shell emission has been detected in X-rays. Recent Spitzer observations revealed an…
XMM-Newton long-look observation of the narrow line Seyfert 1 galaxy PKS0558-504; I: Spectral analysis
I. E. Papadakis, W. Brinkmann, M. Gliozzi +3
We present results from the spectral analysis of a long XMM-Newton observation of the radio-loud NLS1 galaxy PKS0558-504. The source is highly variable, on all sampled time scales.…
Measurements of Secondary Cosmic Microwave Background Anisotropies with the South Pole Telescope
M. Lueker, C. L. Reichardt, K. K. Schaffer +40
We report cosmic microwave background (CMB) power spectrum measurements from the first 100 sq. deg. field observed by the South Pole Telescope (SPT) at 150 and 220 GHz. On angular…
The X-ray to optical-UV luminosity ratio of X-ray selected Type 1 AGN in XMM-COSMOS
E. Lusso, A. Comastri, C. Vignali +29
We present a study of the X-ray to optical properties of a sample of 545 X-ray selected Type 1 AGN, from the XMM-COSMOS survey, over a wide range of redshifts ($0.04<\z<4.25$) and…
The Galactic and Sub-Galactic Environments of Short-Duration Gamma-Ray Bursts: Implications for the Progenitors
Edo Berger, Wen-fai Fong
The study of short-duration gamma-ray bursts (GRBs) has undergone a revolution in recent years thanks to the discovery of the first afterglows and host galaxies in May 2005. In thi…
Solving Lattice QCD systems of equations using mixed precision solvers on GPUs
M. A. Clark, R. Babich, K. Barros +2
