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
* Astronomical algorithms: Development of efficient and optimal
algorithms for research. Examples include: the fast de-dispersion measure
transform, image coaddition and image subtraction.

Working on cosmic explosions, their origins, physics, and how they shape our Universe, from elements to form planets, to the geometry and final fate of the cosmos.
Studying various types of core-collapse SNe, with emphasis on pair instability candidates
and 'Flash-spectroscopy' events - SNe that are caught and followed up within hours from explosion.
Developing and maintaining the TNS
Working on Baryon Acoustic Oscillations and star/galaxy separation in large galaxy surveys (such as the Dark Energy Survey). Investigating the potential of studying exoplanetary systems with the ULTRASAT mission.
Worked on type Ia supernovae, mainly the analysis of high resolution spectra in search for evidence of circumstellar material that might shed some light on the progenitor system of this type of supernova.
