Relativistic Accretion Mediated by Turbulent Comptonization
Aristotle Socrates
Black hole and neutron star accretion flows display unusually high levels of hard coronal emission in comparison to all other optically thick, gravitationally bound, turbulent astr…
On the release of binding energy and accretion power in core collapse-like environments
Aristotle Socrates, Enrico Ramirez-Ruiz
All accretion models of gamma-ray bursts share a common assumption: accretion power and gravitational binding energy is released and then dissipated locally, with the mass of its o…
Effects of Magnetic Field Strength and Orientation on Molecular Cloud Formation
F. Heitsch, J. M. Stone, L. W. Hartmann
We present a set of numerical simulations addressing the effects of magnetic field strength and orientation on the flow-driven formation of molecular clouds. Fields perpendicular t…
Spitzer Planet Limits around the Pulsating White Dwarf GD66
Fergal Mullally, William T. Reach, Steven Degennaro +1
We present infrared observations in search of a planet around the white dwarf, GD66. Time-series photometry of GD66 shows a variation in the arrival time of stellar pulsations cons…
Anisotropic winds from close-in extra-solar planets
James M. Stone, Daniel Proga
We present two-dimensional hydrodynamic models of thermally driven winds from highly irradiated, close-in extra-solar planets. We adopt a very simple treatment of the radiative hea…
The XMM-Newton view of AGN with intermediate mass black holes
G. Miniutti, G. Ponti, J. E. Greene +3
We have observed with XMM-Newton four radiatively efficient active type 1 galaxies with black hole masses < 10^6 Msun, selected optically from the SDSS. We show here that their sof…
Extremely faint high proper motion objects from SDSS stripe 82 - Optical classification spectroscopy of about 40 new objects
R. -D. Scholz, J. Storm, G. R. Knapp +1
(abridged) Deep multi-epoch Sloan Digital Sky Survey data in a 275 square degrees area along the celestial equator (SDSS stripe 82 = S82) allowed us to search for extremely faint (…
Dynamical Tides in Rotating Planets and Stars
Jeremy Goodman, Claire Lackner
Tidal dissipation may be important for the internal evolution as well as the orbits of short-period massive planets--hot Jupiters. We revisit a mechanism proposed by Ogilvie and Li…
The Shapes of Molecular Cloud Cores in Simulations and Observations
S. S. R. Offner, M. R. Krumholz
In this study, we investigate the shapes of starless and protostellar cores using hydrodynamic, self-gravitating adaptive mesh refinement simulations of turbulent molecular clouds.…
Brilliant Pebbles: A Method for Detection of Very Large Interstellar Grains
Aristotle Socrates, Bruce T. Draine
A photon of wavelength lambda ~1 micron interacting with a dust grain of radius a_p ~ 1 mm (a "pebble") undergoes scattering in the forward direction, largely within a small charac…
Limits on Isocurvature Perturbations from Non-Gaussianity in WMAP Temperature Anisotropies
Chiaki Hikage, Kazuya Koyama, Takahiko Matsubara +2
We study the effect of primordial isocurvature perturbations on non-Gaussian properties of CMB temperature anisotropies. We consider generic forms of the non-linearity of isocurvat…
Radiative Feedback in Relic HII Regions at High-Redshift
Andrei Mesinger, Greg L. Bryan, Zoltan Haiman
UV radiation from early astrophysical sources could have a large impact on subsequent star formation in nearby protogalaxies. Here we study the radiative feedback from the first, s…
3D Genus Topology of Luminous Red Galaxies
J. Richard Gott, Yun-Young Choi, Changbom Park +1
We measure the 3D genus topology of large scale structure using Luminous Red Galaxies (LRGs) in the Sloan Digital Sky Survey and find it consistent with the Gaussian random phase i…
The Horizon Run N-body Simulation: Baryon Acoustic Oscillations and Topology of Large Scale Structure of the Universe
Juhan Kim, Changbom Park, J. Richard Gott +1
In support of the new Sloan III survey, which will measure the baryon oscillation scale using the luminous red galaxies (LRGs), we have run the largest N-body simulation to date us…
The Seventh Data Release of the Sloan Digital Sky Survey
K. Abazajian
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDS…
The Atomic to Molecular Transition in Galaxies. II: HI and H_2 Column Densities
Mark R. Krumholz, Christopher F. McKee, Jason Tumlinson
Gas in galactic disks is collected by gravitational instabilities into giant atomic-molecular complexes, but only the inner, molecular parts of these structures are able to collaps…
Southern Cosmology Survey III: QSO's from Combined GALEX and Optical Photometry
Raul Jimenez, David N. Spergel, Michael D. Niemack +4
We present catalogs of QSO candidates selected using photometry from GALEX combined with SDSS in the Stripe 82 region and Blanco Cosmology Survey (BCS) near declination -55 degrees…
CMBPol Mission Concept Study: Foreground Science Knowledge and Prospects
A. A. Fraisse, J. -A. C. Brown, G. Dobler +10
We report on our knowledge of Galactic foregrounds, as well as on how a CMB satellite mission aiming at detecting a primordial B-mode signal (CMBPol) will contribute to improving i…
CMBPol Mission Concept Study: Gravitational Lensing
Kendrick M. Smith, Asantha Cooray, Sudeep Das +10
Gravitational lensing of the cosmic microwave background by large-scale structure in the late universe is both a source of cosmological information and a potential contaminant of p…
CMBPol Mission Concept Study: A Mission to Map our Origins
Daniel Baumann, Asantha Cooray, Scott Dodelson +7
Quantum mechanical metric fluctuations during an early inflationary phase of the universe leave a characteristic imprint in the polarization of the cosmic microwave background (CMB…
A dense disk of dust around the born-again Sakurai's object
Olivier Chesneau, G. C. Clayton, F. Lykou +7
In 1996, Sakurai's object (V4334 Sgr) suddenly brightened in the centre of a faint Planetary Nebula (PN). This very rare event was interpreted as the reignition of a hot white dwar…
