On the Origin of Cores in Simulated Galaxy Clusters
N. L. Mitchell, I. G. McCarthy, R. G. Bower +2
(Abridged) The thermal state of the intracluster medium results from a competition between gas cooling and heating. The heating comes from two distinct sources: gravitational heati…
Further progress on solar age calibration
Günter Houdek, Douglas Gough
We recalibrate a standard solar model seismologically to estimate the main-sequence age of the Sun. Our procedure differs from what we have done in the past by removing from the ob…
High Inclination Planets in Multistellar Systems
P. E. Verrier, N. W. Evans
The Kozai mechanism often destabilises high inclination orbits. It couples changes in the eccentricity and inclination, and drives high inclination, circular orbits to low inclinat…
A Comparison of Six Photometric Redshift Methods Applied to 1.5 Million Luminous Red Galaxies
Filipe B. Abdalla, Manda Banerji, Ofer Lahav +1
We present an updated version of MegaZ-LRG (Collister et al.,(2007)) with photometric redshifts derived with the neural network method, ANNz as well as five other publicly availabl…
An Explicit Scheme for Incorporating Ambipolar Diffusion in a Magnetohydrodynamics Code
Eunwoo Choi, Jongsoo Kim, Paul J. Wiita
We describe a method for incorporating ambipolar diffusion in the strong coupling approximation into a multidimensional magnetohydrodynamics code based on the total variation dimin…
A pilot survey of stellar tidal streams in nearby spiral galaxies
David Martinez-Delgado, R. Jay Gabany, Jorge Penarrubia +4
Within the hierarchical framework for galaxy formation, merging and tidal interactions are expected to shape large galaxies to this day. While major mergers are quite rare at prese…
High Redshift Metals I.: The Decline of C IV at z > 5.3
George D. Becker, Michael Rauch, Wallace L. W. Sargent
We present the results from our search for C IV in the intergalactic medium at redshifts z=5.3-6.0. We have observed four z~6 QSOs with Keck/NIRSPEC in echelle mode. The data are t…
Dynamical Simulations of the Planetary System HD69830
Matthew J. Payne, Eric B. Ford, Mark C. Wyatt +1
HD 69830 exhibits radial velocity variations attributed to three planets as well as infrared emission attributed to a warm debris disk. Previous studies have developed models for t…
Alternative Data Reduction Procedures for UVES: Wavelength Calibration and Spectrum Addition
Rodger I. Thompson, Jill Bechtold, John H. Black +1
This paper addresses alternative procedures to the ESO supplied pipeline procedures for the reduction of UVES spectra of two quasar spectra to determine the value of the fundamenta…
An excess of emission in the dark cloud LDN 1111 with the Arcminute Microkelvin Imager
AMI Consortium, :, A. M. M. Scaife +13
We present observations of the Lynds' dark nebula LDN 1111 made at microwave frequencies between 14.6 and 17.2 GHz with the Arcminute Microkelvin Imager (AMI). We find emission in…
A New Look at Massive Clusters: weak lensing constraints on the triaxial dark matter halos of Abell 1689, Abell 1835, & Abell 2204
Virginia L. Corless, Lindsay J. King, Douglas Clowe
Measuring the 3D distribution of mass on galaxy cluster scales is a crucial test of the LCDM model, providing constraints on the nature of dark matter. Recent work investigating ma…
Compressed sensing imaging techniques for radio interferometry
Y. Wiaux, L. Jacques, G. Puy +2
Radio interferometry probes astrophysical signals through incomplete and noisy Fourier measurements. The theory of compressed sensing demonstrates that such measurements may actual…
Brane inflation revisited after WMAP five-year results
Yin-Zhe Ma, Xin Zhang
In this paper, we revisit brane inflation models with the WMAP five-year results. The WMAP five-year data favor a red-tilted power spectrum of primordial fluctuations at the level…
The shape of primordial non-Gaussianity and the CMB bispectrum
J. R. Fergusson, E. P. S. Shellard
We present a set of formalisms for comparing, evolving and constraining primordial non-Gaussian models through the CMB bispectrum. We describe improved methods for efficient comput…
The excitation of spiral density waves through turbulent fluctuations in accretion discs II: Numerical Simulations with MRI driven turbulence
T. Heinemann, J. C. B. Papaloizou
We present fully three-dimensional local MRI simulations with the object of studying the excitation of non-axisymmetric spiral density waves that are observed to always be present…
The excitation of spiral density waves through turbulent fluctuations in accretion discs I: WKBJ theory
T. Heinemann, J. C. B. Papaloizou
We study and elucidate the mechanism of spiral density wave excitation in a differentially rotating turbulent flow. We formulate a set of wave equations with sources that are only…
Reconstructing Patchy Reionization from the Cosmic Microwave Background
Cora Dvorkin, Kendrick M. Smith
We introduce a new statistical technique for extracting the inhomogeneous reionization signal from future high-sensitivity measurements of the cosmic microwave background temperatu…
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 Spitzer Infrared Nearby Galaxies Survey: A High-Resolution Spectroscopy Anthology
D. A. Dale, J. D. T. Smith, E. A. Schlawin +18
High resolution mid-infrared spectra are presented for 155 nuclear and extranuclear regions from the Spitzer Infrared Nearby Galaxies Survey (SINGS). The fluxes for nine atomic for…
A new determination of the orbit and masses of the Be binary system delta Scorpii
W. J. Tango, J. Davis, A. P. Jacob +5
The binary star delta Sco (HD143275) underwent remarkable brightening in the visible in 2000, and continues to be irregularly variable. The system was observed with the Sydney Univ…
