The Large Array Survey Telescope-Pipeline. II. Image Subtraction and Transient Detection
R. Konno, E. O. Ofek, A. Krassilchtchikov +16
Context. The Large Array Survey Telescope (LAST) is a wide-field visual-band survey designed to explore the variable and transient sky with high cadence. Its raw data stream is aut…
A search for minute-time-scale flares from the transient AT\,2024wpp
Eran O. Ofek, Lior Ozer, Ruslan Konno +21
The AT 2018cow-like fast blue optical transient AT2022tsd showed a large number of few-minute-duration, high-luminosity (~10^43 erg/s) flares. We present an intensive search for su…
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…
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…
Asteroid collisions: expected visibility and rate
E. O. Ofek, D. Polishook, D. Kushnir +9
Asteroid collisions are one of the main processes responsible for the evolution of bodies in the main belt. Using observations of the Dimorphos impact by the DART spacecraft, we es…
UV to near-IR observations of the DART-Dimorphos collision
E. O. Ofek, D. Kushnir, D. Polishook +15
The impact of the Double Asteroid Redirection Test (DART) spacecraft with Dimorphos allows us to study asteroid collision physics, including momentum transfer, the ejecta propertie…
The Large Array Survey Telescope -- Pipeline. I. Basic image reduction and visit coaddition
E. O. Ofek, Y. Shvartzvald, A. Sharon +18
The Large Array Survey Telescope (LAST) is a wide-field telescope designed to explore the variable and transient sky with a high cadence and to be a test-bed for cost-effective tel…
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…
Fermi-LAT Gamma-ray Detection of the Recurrent Nova RS Ophiuchi during its 2021 Outburst
C. C. Cheung, T. J. Johnson, P. Jean +15
We report the Fermi-LAT gamma-ray detection of the 2021 outburst of the symbiotic recurrent nova RS Ophiuchi. In this system, unlike classical novae from cataclysmic binaries, the…
