Previous members

  • Ofer Springer, was a PhD student in my group, working on astronomical algorithms. In his PhD he developed methods for study gravitational lensing. He applied machine leaning for weak gravitational lensing inference in order to decrease the noise due to the large variance in galaxies shape. He also developed new methods for discovery of lensed quasars and measuring their time delays. These methods may have some application also for AGN reverberation mapping.
  • Betina Reyna, was a MSc student in my group.
  • Barak Zackay, was a PhD student in my group on astronomical techniques. During his PhD he developed several methods including the proper image subtraction (Zackay, Ofek, Gal-Yam 2016), proper image coaddition (Ofek & Zackay 2017a,2017b), Fast Dispersion Measure Transform (Zackay & Ofek 2017c), we built a prototype of an optical multiplexer device (Ben-Ami et al. 2014), and developed new techniques including fast solver for phase retrival, and the pruning method. Barak was a postodoc fellow at the Institute for Advanced Studies (Princeton) and he is now a faculty in the Particle physics and astrophysics department in Weizmann.
  • Nora Linn Strotjohann, was a long-term visiting PhD student in my group (from DESY, Germany). She conducted the first search for precursor events among Type IIb supernovae (Strotjohann et al. 2015), and worked on the analysis of the GALEX-PTF supernova sample.
  • Evgeny Gorbikov, was a postdoc in my group working on Type Ibn supernovae.
  • Yifat Dezigan, was a postdoc in my group working on astrometry.
  • Ilia Labzovsky, did a MSc in my group on the supernova environment and host galaxies.
