The GN-z11-Flash Event Can be a Satellite Glint
Guy Nir, Eran O. Ofek, Avishay Gal-Yam
Recently Jiang et al. reported the discovery of a possible short duration transient, detected in a single image, spatially associated with a z~11 galaxy. Jiang et al. and Kahn et a…
A catalog of over ten million variable source candidates in ZTF data release 1
Eran O. Ofek, Maayane Soumagnac, Guy Nir +4
Variable sources probe a wide range of astrophysical phenomena. We present a catalog of over ten million variable source candidates found in Data Release 1 (DR1) of the Zwicky Tran…
Constraints on the Diffuse Flux of Ultra-High Energy Neutrinos from Four Years of Askaryan Radio Array Data in Two Stations
ARA Collaboration, P. Allison, S. Archambault +71
The Askaryan Radio Array (ARA) is an ultra-high energy (UHE, eV) neutrino detector designed to observe neutrinos by searching for the radio waves emitted by the relativi…
Recent Results from The Askaryan Radio Array
ARA Collaboration, P. Allison, S. Archambault +61
The Askaryan Radio Array (ARA) is an ultra-high energy (UHE) neutrino telescope at the South Pole consisting of an array of radio antennas aimed at detecting the Askaryan radiation…
Design and Performance of an Interferometric Trigger Array for Radio Detection of High-Energy Neutrinos
P. Allison, S. Archambault, R. Bard +69
Ultra-high energy neutrinos are detectable through impulsive radio signals generated through interactions in dense media, such as ice. Subsurface in-ice radio arrays are a promisin…
A possible advantage of telescopes with a non-circular pupil
Guy Nir, Barak Zackay, Eran O. Ofek
Most telescope designs have a circular-shape aperture. We demonstrate that telescopes with an elongated pupil have better contrast, at lower separations, between a bright central s…
