A Deep Radio Survey of Abell 2125. III. The Cluster Core: Merging and Stripping
evolution starburst
2014/12/24
We use radio, near-IR, optical, and X-ray observations to examine dynamic processes in the central region of the rich galaxy cluster Abell 2125. In addition to the central triple of E and cD galaxies,...
太阳米波和分米波的射电观测是对太阳爆发过程中耀斑和日冕物质抛射现象研究的重要观测手段。米波和分米波的太阳射电暴以相干等离子体辐射为主导，表现出在时域和频域的多样性和复杂性。其中II 型射电暴是激波在日冕中运动引起电磁波辐射的结果。在II 型射电暴方面，首先对米波II 型射电暴的激波起源问题和米波II 型射电暴与行星际II 型射电暴的关系问题进行了讨论；其次，结合Lin-Forbes 太阳爆发理论模...

Oscillator strengths lifetimes coupled-cluster method
2011/10/18
Transition properties such as oscillator strengths, transition rates, branching ratios and lifetimes of many low-lying states in the doubly ionized scandium (Sc III) are reported. A relativistic metho...
Understanding Compact Object Formation and Natal Kicks. III. The case of Cygnus X-1
Understanding Compact Object Formation Natal Kicks Cygnus X-1
2011/10/20
In recent years, accurate observational constraints become available for an increasing number of Galactic X-ray binaries. Together with proper motion measurements, we could reconstruct the full evolut...
The outcome of protoplanetary dust growth: pebbles, boulders, or planetesimals? III. Sedimentation driven coagulation inside the snow-line
Methods Numerical Planets satellites formation Protoplanetary disks
2011/10/20
We investigate dust growth due to settling in a 1D vertical column of a protoplanetary disk. It is known from the observed 10 micron feature in disk SEDs, that small micron-sized grains are present at...
Formation and Evolution of the Dust in Galaxies. III. The Disk of the Milky Way
Galaxies - Dust Galaxies – Spirals Galaxies – Milky Way
2011/10/13
Models of chemical evolution of galaxies including the dust are nowadays required to decipher the high-z universe. In a series of three papers we have tackled the problem and set a modern chemical evo...
CANGAROO-III observation of TeV gamma rays from the unidentified gamma-ray source HESS J1614-518
CANGAROO-III observation unidentified gamma-ray source HESS J1614-518
2011/10/12
We report the detection, with the CANGAROO-III imaging atmospheric Cherenkov telescope array, of a very high energy gamma-ray signal from the unidentified gamma-ray source HESS J1614-518, which was di...
Velocity Structure and Variability of [O III] Emission in Black Hole Host Globular Cluster RZ2109
Velocity Structure Variability Emission Globular Cluster
2011/10/12
We present a multi-facility study of the optical spectrum of the extragalactic globular cluster RZ2109, which hosts a bright black hole X-ray source. The optical spectrum of RZ2109 shows strong and ve...
The Optical Gravitational Lensing Experiment. OGLE-III Photometric Maps of the Galactic Bulge Fields
Optical Gravitational Lensing Experiment OGLE-III Photometric Galactic Bulge Fields
2011/10/12
We present OGLE-III Photometric Maps of the Galactic bulge fields observed during the third phase of the OGLE project. This paper describes the last, concluding set of maps based on OGLE-III data.
Th...
The Nature of Double-Peaked [O III] Active Galactic Nuclei
Nature Double-Peaked [O III] Active Galactic Nuclei
2011/10/11
Active galactic nuclei (AGNs) with double-peaked [O III] lines are suspected to be sub-kpc or kpc-scale binary AGNs. However, pure gas kinematics can produce the same double-peaked line profile in spa...
The Optical Gravitational Lensing Experiment. Analysis of the bulge RR Lyrae population from the OGLE-III data
Optical Gravitational Lensing Experiment Analysis bulge population
2011/10/10
We have analyzed data on 16,838 RR Lyrae variables observed toward the Galactic bulge during the third phase of the Optical Gravitational Lensing Experiment (OGLE) in 2001-2009. Using this type of sta...
We show that matter yukawa couplings of the New Minimal Supersymmetric (SO(10)) GUT(NMSGUT) are subject to very significant GUT scale threshold corrections. Including these threshold effects relaxes t...
