Tidal stirring of Milky Way satellites: a simple picture with the integrated tidal force
stirring of Milky Way satellites simple picture integrated tidal force
2010/11/16
Most of dwarf spheroidal galaxies in the Local Group were probably formed via environmental processes like the tidal interaction with the Milky Way.We study this process via N-body simulations of dwar...
Galaxy clustering and projected density profiles as traced by satellites in photometric surveys: Methodology and luminosity dependence
Galaxy clustering projected density profiles photometric surveys
2010/11/12
We develop a new method which measures the projected density distribution wp(rp)n of photometric galaxies surrounding a set of spectroscopically-identified galaxies, and simultaneously the projected c...
Where are the Fossils of the First Galaxies? II. True Fossils, Ghost Halos, and the Missing Bright Satellites
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We use a new set of cold dark matter simulations of the local universe to investigate the distribution of fossils of primordial dwarf galaxies within, and around the Milky Way.
The Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) mission: design, execution, and first results
the Troposphere Aircraft and Satellites (ARCTAS) mission first results
2010/8/13
The NASA Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) mission was conducted in two 3-week deployments based in Alaska (April 2008) and western Canada (Ju...
Right now, 10 to 15 Rubik’s Cube-sized satellites are orbiting high above Earth. Known as cube satellites, or “CubeSats,” the devices help researchers conduct simple space observations and measure cha...
On the potential of sub-mm passive MW observations from geostationary satellites to retrieve heavy precipitation over the Mediterranean Area
sub-mm passive MW geostationary satellites
2010/1/27
The general interest in the potential use of the mm and sub-mm frequencies up to 425 GHz resolution from geostationary orbit is increasing due to the fact that the frequent time sampling and the compa...
On possible a-priori "imprinting" of General Relativity itself on the performed Lense-Thirring tests with LAGEOS satellites
Experimental studies of gravity Satellite orbits Harmonics of the gravity potential field
2010/3/18
The impact of possible a-priori "imprinting" effects of general relativity itself on recent attempts to measure the Lense-Thirring precessions with the LAGEOS satellites orbiting the Earth and the ter...

An Assessment of the Capabilities of the ERS Satellites' Active Microwave Instruments for Monitoring Soil Moisture Change
European Remote sensing Monitoring Soil Moisture Change active microwave instrument
2009/6/8
The launch of the European Remote sensing Satellite (ERS-1) in July 1991 represented an important turning point in the development of Earth observation as it was the first of a series of satellites wh...

Utilization of GPS Satellites for Precise Irradiation Measurement and Monitoring
Albedo global positioning system solar irradiation
2009/5/6
Precise measurement of irradiance over the earth under various
circumstances like solar flares, coronal mass ejections, over an 11-year
solar cycle, etc. leads to better understanding of Sun–earth r...

Internal Waves in the Strait of Messina Studied by a Numerical Model and Synthetic Aperture Radar Images from the ERS 1/2 Satellites
synthetic aperture radar Numerical Model ERS
2008/11/18
A new numerical two-layer model is presented, which describes the generation of internal tidal bores and their disintegration into internal solitary waves in the Strait of Messina. This model is used ...
Retrieving global aerosol sources from satellites using inverse modeling
Retrieving global aerosol sources satellites inverse modeling
2008/10/27
Understanding aerosol effects on global climate requires knowing the global distribution of tropospheric aerosols. By accounting for aerosol sources, transports, and removal processes, chemical transp...
