NSF Forecast Space Weather,Power Grid Pipelines Satellites
2017/12/4
While Earth's weather reports center on precipitation, temperature, wind direction and velocity, and humidity, space weather forecasts attempt to predict activity that occurs on the sun -- and how the...
Tidal stirring of Milky Way satellites: a simple picture with the integrated tidal force
stirring of Milky Way satellites simple picture integrated tidal force
2010/11/1
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
2010/11/1
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...
