THE SIZE EVOLUTION OF PASSIVE GALAXIES: OBSERVATIONS FROM THE WIDE FIELD CAMERA 3 EARLY RELEASE SCIENCE PROGRAM
red galaxies isolates galaxies
2014/12/22
We present results on the size evolution of passively evolving galaxies at 1 . z . 2 drawn from the Wide Field Camera 3 Early Release Science program. Our sample was constructed using an analog to the...
SUPERNOVA REMNANTS AND THE INTERSTELLAR MEDIUM OF M83: IMAGING AND PHOTOMETRY WITH THE WIDE FIELD CAMERA 3 ON THE HUBBLE SPACE TELESCOPE
supernova star-forming galaxy M83
2014/12/20
We present Wide Field Camera 3 images taken with the Hubble Space Telescope within a single field in the southern grand design star-forming galaxy M83. Based on their size, morphology, and photometry ...
The LTHE LUMINOSITY, MASS, AND AGE DISTRIBUTIONS OF COMPACT STAR CLUSTERS IN M83 BASED ON HUBBLE SPACE TELESCOPE/WIDE FIELD CAMERA 3 OBSERVATIONS
filters binning
2014/12/20
The newly installed Wide Field Camera 3 (WFC3) on the Hubble Space Telescope has been used to obtain multi-band images of the nearby spiral galaxy M83. These new observations are the deepest and highe...
Observations and Analysis of High-Resolution Magnetic Field Structures in Molecular Clouds
Observations Analysis High-Resolution Magnetic Field Structures Molecular Clouds
2012/2/23
Recent high-angular-resolution (up to 0.7") dust polarization observations toward star forming regions are summarized. With the Sub-Millimeter Array, the emission from the dense structures is traced a...
2MASS wide field extinction maps: IV. The Orion, Mon R2, Rosette, and Canis Major star forming regions
clouds dust extinction structure individual objects Orion molecular complex
2011/10/21
We present a near-infrared extinction map of a large region (approximately 2200 deg^2) covering the Orion, the Monoceros R2, the Rosette, and the Canis Major molecular clouds. We used robust and optim...
Identification of field dwarfs and giants in RAVE
surveys–catalogues–techniques: photometric
2011/10/13
The second RAdial Velocity Experiment (RAVE) Data Release (DR2) derives log g values but we present a simpler and cleaner method of identifying dwarfs and giants using only magnitudes, which does not ...
The field of Loden 112
field Loden spatially correlated
2011/10/12
Based on the available uvbybeta photometry of OB stars in the longitude range 281 - 285 deg in the Galactic disk, we identify a feature of young stars at 1630+/-82 pc, that is probably connected to th...
Magnetic properties of quark matter are discussed in the light of the observation of pulsars. Our works about spontaneous spin polarization and spin density wave are reviewed and their implications on...

2011/9/28
Only for very few beta Cephei stars has the behaviour of the magnetic field been studied over the rotation cycle. During the past two years we have obtained multi-epoch polarimetric spectra of the bet...
Faraday Rotation Measure due to the Intergalactic Magnetic Field II: the Cosmological Contribution
Intergalactic Magnetic Field II Cosmological Contribution
2011/9/26
We investigate the Faraday rotation measure (RM) due to the intergalactic magnetic field (IGMF) through the cosmic web up to cosmological distances, using a model IGMF based on turbulence dynamo in th...
New Constraints on the Primordial Magnetic Field
primordial magnetic field numerical analysis
2010/3/19
We present the newest statistical and numerical analysis of the matter and cosmic microwave background power spectrum with effects of the primordial magnetic field (PMF) included. New limits to the PM...
SGRs and AXPs：Evidence for Delayed Amplification of Magnetic Field after Neutron Star Formation?
Anomalous X-ray Pulsars soft gamma-ray repeaters supernova remnants
2009/9/4
We present new analysis of the birth rate of AXPs and SGRS and their associated SNRs. Using Kolmogorov-Smirnov statistics together with parametric fits based on a robust estimator, we find a birth rat...
