Co-addition and Subtraction of Undersampled Images
Matan Schlanger, Barak Zackay
In astronomical imaging surveys, repeated observations of the same sky patches are taken in order to obtain deeper images and detect new sources. This is the case in the search for…
TRANSLIENT: Detecting Transients Resulting from Point Source Motion or Astrometric Errors
O. Springer, E. O. Ofek, B. Zackay +10
Detection of moving sources over complicated background is important for several reasons. First is measuring the astrophysical motion of the source. Second is that such motion resu…
A linearized approach to radial velocity extraction
Sahar Shahaf, Barak Zackay
High-precision radial velocity (RV) measurements are crucial for exoplanet detection and characterisation. Efforts to achieve ~10 cm/s precision have been made over the recent deca…
ULTRASAT: A wide-field time-domain UV space telescope
Y. Shvartzvald, E. Waxman, A. Gal-Yam +41
The Ultraviolet Transient Astronomy Satellite (ULTRASAT) is scheduled to be launched to geostationary orbit in 2026. It will carry a telescope with an unprecedentedly large field o…
The Large Array Survey Telescope -- System Overview and Performances
E. O. Ofek, S. Ben-Ami, D. Polishook +38
The Large Array Survey Telescope (LAST) is a wide-field visible-light telescope array designed to explore the variable and transient sky with a high cadence. LAST will be composed…
A reduction procedure and pipeline for the detection of trans-Neptunian objects using occultations
Guy Nir, Eran O. Ofek, Barak Zackay
Kuiper belt objects smaller than a few kilometers are difficult to observe directly. They can be detected when they randomly occult a background star. Close to the ecliptic plane,…
