The Weizmann Fast Astronomical Survey Telescope (W-FAST): System Overview

Guy Nir, Eran O. Ofek, Sagi Ben-Ami +8

A relatively unexplored phase space of transients and stellar variability is that of second and sub-second time-scales. We describe a new optical observatory operating in the Negev…

A high-rate foreground of sub-second flares from geosynchronous satellites

Guy Nir, Eran O. Ofek, Sagi Ben-Ami +3

The Weizmann Fast Astronomical Survey Telescope (W-FAST) is a 55cm optical survey telescope with a high cadence (25Hz) monitoring of the sky over a wide field of view (~7deg^2). Th…

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…

Optimal and Efficient Streak Detection in Astronomical Images

Guy Nir, Barak Zackay, Eran O. Ofek

Identification of linear features (streaks) in astronomical images is important for several reasons, including: detecting fast-moving near-Earth asteroids; detecting or flagging fa…
