BASELINE ERROR ANALYSIS AND EXPERIMENTAL VALIDATION FOR HEIGHT MEASUREMENT OF FORMATION INSAR SATELLITE
InSAR Height Measurement Baseline Error DEM Simulation Validation SRTM TerraSAR-X/TanDEM-X
font style='font-size:12px;'>
2018/5/14
In this paper, we proposed the stochastic model of InSAR height measurement by considering the interferometric geometry of InSAR height measurement. The model directly described the relationship betwe...
Depth profiling analysis of solar wind helium collected in diamond-like carbon film from Genesis
solar wind depth profile helium NASA Genesis mission post-ionization
font style='font-size:12px;'>
2017/4/10
The distribution of solar-wind ions in Genesis mission collectors, as determined by depth profiling analysis, constrains
the physics of ion-solid interactions involving the solar wind. Thus, they pro...
The Galactic Central Diffuse X-Ray Enhancement: A Differential Absorption/Emission Analysis
3C 273 Mrk 421
font style='font-size:12px;'>
2014/12/23
The soft X-ray background shows a general enhancement toward the inner region of the Galaxy. But whether this enhancement is a local feature (e.g., a superbubble within a distance of 200 pc) and/or a ...
Spitzer spectral line mapping of supernova remnants. I. Basic data and principal component analysis
Molecules Abundances
font style='font-size:12px;'>
2014/12/23
We report the results of spectroscopic mapping observations carried out toward small (1' × 1') regions within the supernova remnants W44, W28, IC 443, and 3C 391 using the Infrared Spectrograph (IRS) ...
The pulsar B2224+65 and its jets: a two epoch X-ray analysis
X-ray B2224+65
font style='font-size:12px;'>
2014/12/22
We present an X-ray morphological and spectroscopic study of the pulsar B2224+65 and its apparent jet-like X-ray features based on two epoch Chandra observations. The main X-ray feature, which shows a...
The evolution of globular clusters: Analysis of external effects and determination of progenitor populations
Globular cluster evolution Evolution The Milky Way. Base elliptical galaxies galaxy
font style='font-size:12px;'>
2014/12/9
We include external effects in the Fokker-Planck scheme for studying globular cluster evolution. We use this method to study cluster evolution under the combined influence of relaxation, tidal heating...
Characterizing Distant Galaxies: Spectral Energy Distribution Analysis of X-ray Selected Star Forming Galaxies

font style='font-size:12px;'>
2014/12/9
Comprehensive and robust analysis of galaxies found throughout cosmic time provides the means to probe the underlying characteristics of our Universe. Coupling observations and theory, spectral energy...
Observations and Analysis of High-Resolution Magnetic Field Structures in Molecular Clouds
Observations Analysis High-Resolution Magnetic Field Structures Molecular Clouds
font style='font-size:12px;'>
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...
The Progenitor Mass of SN 2011dh from Stellar Populations Analysis
Progenitor Mass Stellar Populations Analysis
font style='font-size:12px;'>
2011/10/18
Using Hubble Space Telescope (HST) photometry, we characterize the age of the stellar association in the vicinity of supernova (SN) 2011dh and use it to infer the zero-age main sequence mass (M_{ZAMS}...
A CoGeNT Modulation Analysis
CoGeNT Modulation Analysis
font style='font-size:12px;'>
2011/10/18
We analyze the recently released CoGeNT data with a focus on their time-dependent properties. Using various statistical techniques, we confirm the presence of modulation in the data, and find a signif...
Spectroscopic analysis of interaction between an EIT wave and a coronal upflow region
Spectroscopic analysis of interaction between an EIT wave and a coronal upflow region
font style='font-size:12px;'>
2011/10/20
We report a spectroscopic analysis of an EIT wave event that occurred in active region 11081 on 2010 June 12 and was associated with an M2.0 class flare. The wave propagated near circularly. The south...
Pulsar timing analysis in the presence of correlated noise
pulsars: general – methods: data analysis
font style='font-size:12px;'>
2011/10/17
Pulsar timing observations are usually analysed with least-square-fitting procedures under the assumption that the timing residuals are uncorrelated (statistically "white"). Pulsar observers are well ...
