Gamma-Ray Parsec-Scale Jet Properties Complete Sample Blazars From MOJAVE Program
2011/10/19
We investigate the Fermi LAT gamma-ray and 15 GHz VLBA radio properties of a joint gamma-ray- and radio-selected sample of AGNs obtained during the first 11 months of the Fermi mission (2008 Aug 4 - 2...
The peculiar properties of horizontal branch stars in omega Centauri
peculiar properties horizontal branch stars omega Centauri
2011/10/20
We measured temperatures, gravities, and masses for a large sample of blue horizontal branch stars in omega Centauri, comparing the results with theoretical expectations for canonical and He-enriched ...
Kepler Mission Stellar and Instrument Noise Properties
Kepler Mission Stellar and Instrument Noise Properties
2011/10/20
Kepler Mission results are rapidly contributing to fundamentally new discoveries in both the exoplanet and asteroseismology fields. The data returned from Kepler are unique in terms of the number of s...
X-ray properties expected from AGN feedback in elliptical galaxies
X-ray properties expected feedback elliptical galaxies
2011/10/11
The ISM evolution of elliptical galaxies experiencing feedback from accretion onto a central black hole was studied recently with high-resolution 1D hydrodynamical simulations including radiative heat...
Atomic data for neutron-capture elements II. Photoionization and recombination properties of low-charge krypton ions
atomic data - atomic processes - HII regions - nucleosynthesis, abundances - planetary nebulae: general - stars:evolution
2011/10/12
We present multi-configuration Breit-Pauli distorted-wave photoionization (PI) cross sections and radiative recombination (RR) and dielectronic recombination (DR) rate coefficients for the first six k...
Properties of the negative effective magnetic pressure instability
magnetohydrodynamics (MHD) – instabilities – turbulence
2011/10/9
As was demonstrated in earlier studies, turbulence can result in a negative contribution to the effective mean magnetic pressure, which, in turn, can cause a large-scale instability. In this study, hy...

ISM – abundances HII regions ISM:stars: pre-main-sequence protostars protoplan- etary disks
2011/9/29
Integral field spectroscopy of the LV2 proplyd is presented taken with the VLT/FLAMES Argus array at an angular resolution of 0.31x0.31 arcsec^2 and velocity resolutions down to 2 km/s per pixel. Foll...
The Interaction of High-Speed Turbulence with Flames: Global Properties and Internal Flame Structure
Turbulent premixed combustion, Turbulence, Flamelet, Flame structure, Hydrogen
2011/9/14
We study the dynamics and properties of a turbulent flame, formed in the presence of subsonic, high-speed, homogeneous,isotropic Kolmogorov-type turbulence in an unconfined system. Direct numerical si...
γ-ray properties of the CJF sample: Revisiting the beaming hypothesis
γ-ray properties the CJF sample
2011/1/10
The recent release of the First Fermi-LAT Source Catalog solidified the predominant association of extragalactic {\gamma}-ray emitters to active galaxies, in particular blazars. A tight connection bet...
Project Icarus: A Review of Local Interstellar Medium Properties of Relevance for Space Missions to the Nearest Stars
Project Icarus Local Interstellar Medium Properties
2011/1/10
I review those properties of the interstellar medium within 15 light-years of the Sun which will be relevant for the planning of future rapid ($v /ge 0.1c$) interstellar space missions to the nearest ...
Spectra disentangling applied to the Hyades binary Theta^2 Tau AB: new orbit, orbital parallax and component properties
the Hyades binary Theta^2 Tau AB orbital parallax component properties
2011/1/11
Theta^2 Tauri is a detached and single-lined interferometric-spectroscopic binary as well as the most massive binary system of the Hyades cluster. The system revolves in an eccentric orbit with a peri...
