Cosmological Constraints from Sunyaev-Zel'dovich-Selected Clusters with X-ray Observations in the First 178 Square Degrees of the South Pole Telescope Survey
B. A. Benson, T. de Haan, J. P. Dudley +73
We use measurements from the South Pole Telescope (SPT) Sunyaev Zel'dovich (SZ) cluster survey in combination with X-ray measurements to constrain cosmological parameters. We prese…
Evolution of the IVOA Characterisation Data Model
Francois Bonnarel, Mireille Louys, Igor Chilingarian
The Characterisation data model is a standard of the International Virtual Observatory Alliance (IVOA) that describes observational datasets in the multi-dimensional parameter spac…
The circumnuclear environment of IRAS 20551-4250 a case study of AGN/Starburst connection for JWST
E. Sani, E. Nardini
We present a general review of the current knowledge of IRAS 20551-4250 and its circumnuclear environment. This Ultraluminous Infrared Galaxy is one of the most puzzling sources of…
Warm Absorbers and Outflows in the Seyfert-1 Galaxy NGC 4051
Ashley L. King, Jon M. Miller, John Raymond
We present both phenomenological and more physical photoionization models of the Chandra HETG spectra of the Seyfert-1 AGN NGC 4051. We detect 40 absorption and emission lines, enc…
Galactic structure based on the ATLASGAL 870mum survey
H. Beuther, J. Tackenberg, H. Linz +11
The ATLASGAL 870mum continuum survey conducted with the APEX telescope is the first survey covering the whole inner Galactic plane (60deg>l>-60deg & b<1.5deg) in submm continuum em…
Discovery of the Youngest Molecular Outflow associated with an Intermediate-mass protostellar Core, MMS-6/OMC-3
Satoko Takahashi, Paul Ho
We present sub-arcsecond resolution HCN (4-3) and CO (3-2) observations made with the Submillimeter Array (SMA), toward an extremely young intermediate-mass protostellar core, MMS…
Atomic homodyne detection of continuous variable entangled twin-atom states
C. Gross, H. Strobel, E. Nicklas +4
Historically, the completeness of quantum theory has been questioned using the concept of bipartite continuous variable entanglement. The non-classical correlations (entanglement)…
Two Earth-sized planets orbiting Kepler-20
Francois Fressin, Guillermo Torres, Jason F. Rowe +33
Since the discovery of the first extrasolar giant planets around Sun-like stars, evolving observational capabilities have brought us closer to the detection of true Earth analogues…
VERITAS Observations of day-scale flaring of M87 in 2010 April
E. Aliu, T. Arlen, T. Aune +88
VERITAS has been monitoring the very-high-energy (VHE; >100GeV) gamma-ray activity of the radio galaxy M87 since 2007. During 2008, flaring activity on a timescale of a few days wa…
Star Formation Rates in Molecular Clouds and the Nature of the Extragalactic Scaling Relations
Charles J. Lada, Jan Forbrich, Marco Lombardi +1
In this paper we investigate scaling relations between star formation rates and molecular gas masses for both local Galactic clouds and a sample of external galaxies. We specifical…
The X-ray light curve of Gamma-ray bursts: clues to the central engine
M. G. Bernardini, R. Margutti, J. Mao +2
We present the analysis of a large sample of gamma-ray burst (GRB) X-ray light curves in the rest frame to characterise their intrinsic properties in the context of different theor…
Absolute dimensions of eclipsing binaries. XXIX. The Am-type systems SW Canis Majoris and HW Canis Majoris
G. Torres, J. V. Clausen, H. Bruntt +5
CONTEXT: Accurate physical properties of eclipsing stars provide important constraints on models of stellar structure and evolution, especially when combined with spectroscopic inf…
The ongoing assembly of a central cluster galaxy: Phase-space substructures in the halo of M87
Aaron J. Romanowsky, Jay Strader, Jean P. Brodie +5
The halos of galaxies preserve unique records of their formation histories. We carry out the first combined observational and theoretical study of phase-space halo substructure in…
Old Massive Globular Clusters and the Stellar Halo of the Dwarf Starburst Galaxy NGC 4449
Jay Strader, Anil C. Seth, Nelson Caldwell
We use Hubble Space Telescope imaging to show that the nearby dwarf starburst galaxy NGC 4449 has an unusual abundance of luminous red star clusters. Joint constraints from integra…
The TW Hya Disk at 870 microns: Comparison of CO and Dust Radial Structures
Sean M. Andrews, David J. Wilner, A. M. Hughes +9
We present high resolution (0.3" = 16 AU), high signal-to-noise ratio Submillimeter Array observations of the 870 microns (345 GHz) continuum and CO J=3--2 line emission from the p…
Apparent motion of a spherical shell collapsing onto a black hole
Robert F. Penna
We model the collapse of a spherically symmetric, constant density, pressureless shell onto a preexisting black hole. Contrary to a recent claim of Liu and Zhang (2009), we show th…
Attosecond streaking of correlated two-electron transitions in helium
Renate Pazourek, Stefan Nagele, Johannes Feist +1
We present fully ab initio simulations of attosecond streaking for ionization of helium accompanied by shake-up of the second electron. This process represents a prototypical case…
Period Estimation in Astronomical Time Series Using Slotted Correntropy
Pablo Huijse, Pablo A. Estévez, Pablo Zegers +2
In this letter, we propose a method for period estimation in light curves from periodic variable stars using correntropy. Light curves are astronomical time series of stellar brigh…
