X-Sifter: detecting transients in X-ray data using the optimal Poisson matched filter
Maayane T. Soumagnac, Eran O. Ofek, Shachar S. Israeli +2
We present X-sifter, a software package designed for near-optimal detection of sources in X-ray images and other forms of photon images in the Poisson-noise regime. The code is bas…
Accurate photometric calibration by fitting the system transmission
S. Garrappa, E. O. Ofek, S. Ben-Ami +10
Transforming the instrumental photometry of ground-based telescopes into a calibrated physical flux in a well-defined passband is a major challenge in astronomy. Along with the int…
An efficient observational strategy for the detection of the Oort cloud
Eran O. Ofek, Sarah A. Spitzer, Guy Nir
The Oort cloud is presumably a pristine relic of the Solar System formation. Detection of the Oort cloud may provide information regarding the stellar environment in which the Sun…
HighSpec: A High-Resolution Spectrograph for the MAST Telescope Array
Yahel Sofer Rimalt, Sagi Ben-Ami, Eran Ofek +13
We present the updated design of HighSpec, a high-resolution spectrograph designed for the Multi Aperture Spectroscopic Telescope (MAST). HighSpec offers…
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…
