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 Kann et al. suggested the transient originates from a γ-Ray Burst (GRB), while Padmanabhan & Loeb argued the flash is consistent with a supernova shock breakout event of a 300 M ⊙ Population III star. Jiang et al. argued against the possibility that this event originated from light reflected off a satellite. Here we show…

GN-z11-flash was a signal from a man-made satellite not a gamma-ray burst at redshift 11

Long gamma-ray bursts (GRB), explosions of very massive stars, provide crucial information on stellar and galaxy evolution, even at redshifts z ~ 8 - 9.5, when the Universe was only 500-600 million…

The rate of satellite glints in ZTF and LSST sky surveys

We assess the impact of satellite glints -- rapid flashes produced by reflections of a sunlight from flat surfaces of rotating satellites -- on current and future deep sky surveys such as the ones…

L. Jiang et al. reply

In Jiang et al. 1 , we reported the detection of a bright flash (here-after GN-z11-flash) that appeared as a compact continuum emission feature during our Keck MOSFIRE observations 2 of the galaxy…

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

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

Asteroid Collisions: Expected Visibility and Rate

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 estimate how asteroid…

Aggregate Effects of Proliferating LEO Objects and Implications for Astronomical Data Lost in the Noise

The rising population of artificial satellites and associated debris in low-altitude orbits is increasing the overall brightness of the night sky, threatening ground-based astronomy as well as a…

Aggregate effects of proliferating low-Earth-orbit objects and implications for astronomical data lost in the noise

Flares from Space Debris in LSST Images

Owing to the exceptional sensitivity of the Vera C. Rubin Observatory, we predict that its upcoming LSST images will be contaminated by numerous flares from centimeter-scale space debris in Low Earth…

A possible bright ultraviolet flash from a galaxy at redshift z ≈ 11

In the optical sky, minutes-duration transients from cosmological distances are rare. Known objects that give rise to such transients include gamma-ray bursts (GRBs), the most luminous explosions in…

A more probable explanation for a continuum flash in the direction of a redshift $\approx$ 11 galaxy

Recent work reported the discovery of a gamma-ray burst (GRB) associated with the galaxy GNz11 at z ∼ 11. The extreme improbability of the transient source being a GRB in the very early Universe…

"A more probable explanation"is still impossible to explain GN-z11-flash: in response to Steinhardt et al. (arXiv:2101.12738)

In Jiang et al. (2020), we reported a possible bright flash (hereafter GN-z11-flash) from a galaxy GN-z11 at z ≈ 11. Recently, Steinhardt et al. (2021; arXiv:2101.12738) found 27 images with…
