Our research is focused on observational astrophysics:
* Cosmic explosions and transients: the catastrophic deaths of stars. Huge amounts of energy are released within hours in events so bright they are seen from the edge of the Universe. The resulting extreme physical conditions involve huge densities, pressures and temperatures, strong magnetic fields, nuclear and high energy particle reactions, and strong relativistic effects (special and general). These topics are at the forefront of research in high energy particle astrophysics and gravity theories, with diverse implications from the sources of life to cosmology.
* Instrumentation: Design and construction of astronomical instruments and instrumental concepts. Among our instrumental projects are the construction of the W-FAST 55-cm Schmidt telescopes for searching for and characterizing small bodies in the Kuiper belt and the Oort cloud, as well as imaging multiplexer prototypes.
* Astronomical algorithms: Development of efficient and optimal algorithms for research. Examples include: the fast de-dispersion measure transform, image coaddition and image subtraction.
