Galactic white dwarf binaries are important sources for space-borne gravitational wave (GW) observatories like LISA. In this project, we will model GW signals by eccentric white dwarf binaries, and test the detectability of such systems.
Solar flares release a large amount of energy stored in the Sun's magnetic field by a mechanism called magnetic reconnection. In this project, student will analyze state-of-the-art observations of flares, and measure properites of magnetic reconnection that governs energy release in flares.
Solar flares and coronal mass ejections are intense explosive energy release in the solar system. In this project, students will analyze observations by NASA's Solar Dynamics Observatory to search for and characterize early signatures, in order to understand physical mechanisms triggering solar eruptions.
Solar energetic particles are produced in a variety of explosive solar events, such as by the shocks driven by Coronal Mass Ejections. In this project, students will analyze satellite observations of these particles, and examine their evolution in the heliosphere, which is important for space weather forecast.
Our Sun is a variable star, and the amount of its radiation rises and falls every 11 years or so. The radiation from the Sun received at the earth (irradiance) varies over the activity cycle, and also varies with the observing wavelength. In this project, we will derive the long-term variation of the Sun's irradiance in soft X-rays.
Accretion onto black holes is one of the most efficient processes for emitting energy from matter in the Universe. In this project, students will analyze radio observations and study jets from accreting supermassive black holes.
In this project, we will measure scattered moonlight with polarization imaging, and use these measurements to study the atmosphere. Student will participating in making observational measurements and data analysis.
