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
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...

Six Decade Old Space Mystery Shoebox-Sized Satellite CubeSat
2017/12/19
A 60-year-old mystery about the source of energetic, potentially damaging particles in Earth's radiation belts has been solved using data from a shoebox-sized satellite built and operated by students....
Spin-up of rubble-pile asteroids:Disruption,satellite formation,and equilibrium shapes
Asteroid, Dynamics Rotational dynamics Satellites,Dynamics
2015/12/25
We present results from numerical experiments testing the behavior of cohesionless gravitational aggregates experiencing a gradual increase of angular momentum. The test bodies used in these numerical...

Earth-spaceand satellite-to-satellite Space plasma
2015/9/14
This paper summarizes the the activities carried out by Working Group 4 of COST 271 Action. The structure of this Working Group included four Working packages that were dealing with different aspects ...
Theoretical models of the halo occupation distribution: Separating central and satellite galaxies
formation halos
2014/12/24
The halo occupation distribution (HOD) describes the relation between galaxies and dark matter at the level of individual dark matter halos. The properties of galaxies residing at the centers of halos...
Submillimeter Wave Astronomy Satellite observations of Comet 9P/Tempel 1 and Deep Impact
Comet Tempel-1 Radiative Transfer Radio Observations Comets
2014/12/23
On 4 July 2005 at 5:52 UT the Deep Impact mission successfully completed its goal to hit the nucleus of 9P/Tempel 1 with an impactor, forming a crater on the nucleus and ejecting material into the com...
The growth of central and satellite galaxies in cosmological smoothed particle hydrodynamics simulations
theory formation
2014/12/23
We examine the accretion and merger histories of central and satellite galaxies in a smoothed particle hydrodynamics (SPH) cosmological simulation that resolves galaxies down to 7 × 109 M⊙. Most frien...
The dynamics of satellite disruption in cold dark matter haloes
numerical N-body simulation
2014/12/22
We investigate the physical mechanisms of tidal heating and satellite disruption in cold dark matter host haloes using N-body simulations based on cosmological initial conditions. We show the importan...

Detectability optical Gaia satellite
2011/10/9
With the launch of Gaia satellite, detection of many different types of transient sources will be possible, one of them being optical afterglows of gamma-ray bursts (GRBs). Using the knowledge of the ...
Global Distribution of Fe K alpha Lines in the Galactic Center Region Observed with the Suzaku Satellite
Galaxy: Center—Inter stellar medium— X-ray spectra
2011/10/9
We have surveyed spatial profiles of the Fe K$\alpha$ lines in the Galactic center diffuse X-rays (GCDX), including the transient region from the GCDX to the Galactic ridge X-ray emission (GRXE), with...
Can a Satellite Galaxy Merger Explain the Active Past of the Galactic Center?
Satellite Galaxy Merger Explain Active Past Galactic Center
2011/10/9
Observations of the Galactic Center (GC) have accumulated a multitude of "forensic" evidence indicating that several million years ago the center of the Milky Way galaxy was teaming with starforming a...
