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…
Minutes-duration Optical Flares with Supernova Luminosities
Anna Y. Q. Ho, Daniel A. Perley, Ping Chen +74
In recent years, certain luminous extragalactic optical transients have been observed to last only a few days. Their short observed duration implies a different powering mechanism…
A Deficit of Massive White Dwarfs in Gaia Astrometric Binaries
Na'ama Hallakoun, Sahar Shahaf, Tsevi Mazeh +2
The third data release of Gaia introduced a large catalog of astrometric binaries, out of which about 3,200 are likely main-sequence stars with a white-dwarf (WD) companion. These…
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…
Triage of the Gaia DR3 astrometric orbits. II. A census of white dwarfs
S. Shahaf, N. Hallakoun, T. Mazeh +4
The third data release of Gaia was the first to include orbital solutions assuming non-single stars. Here, we apply the astrometric triage technique of Shahaf et al. to identify bi…
First on-sky results of a FIOS prototype, a Fabry Perot Based Instrument for Oxygen Searches
Surangkhana Rukdee, Sagi Ben-Ami, Mercedes López-Morales +4
The upcoming Extremely Large Telescopes (ELTs) are expected to have the collecting area required to detect potential biosignature gases such as molecular oxygen, , in…
