TAOS Detects Twinkles of a Black Hole
On June 15th, 2015, one of black-hole binaries closest to Earth, V404 Cyg, underwent an outburst after 26 years of quiescence. The outburst was first detected by the Burst Alert Telescope on NASA's Swift satellite, which sent out an alert. TAOS telescopes automatically responded to the alert, and started to observe the black hole at 150 sec after the outburst detection. This was the earliest optical observation among numerous amount of observations by many instruments around the world trig...
TAOS publishes new paper presenting upper limits on the surface density of small Kuiper Belt Objects
In a new paper published in the Astronomical Journal, the TAOS Collaboration has reported new upper limits on the surface density of small Kuiper Belt Objects. The new limits are the strongest published limits to date on objects with diameters between 0.7 and 30 km.
In a new paper published in the Astronomical Journal, the TAOS Collaboration has reported the discovery of 15 previously unknown variable stars.
The TAOS collaboration has discovered 41 previously unknown low-amplitude δ-Scuti stars. The results are published in a new paper in the Astronomical Journal.

TAOS Detects Afterglow to GRB 090424
Three 50cm TAOS telescopes, located at Lulin observatory, Taiwan, started to observe GRB 090424 field (Cannizzo et al.; GCN 9223) at 94s after the trigger. The optical afterglow (Yuan et al., GCN 9224; Xin et al. GCN 9225) was clearly detected in images taken by TAOSA (25s exposure), TAOSB (5s exposure), and TAOSD (1s exposure). Brightness of the afterglow was about R~13.08 at 94s post the burst. Our R-band magnitudes were calibrated with USNOB red stars....
TAOS Detects Transit of Exoplanet XO-2b
Using the TAOS telescopes, we observed a transit of a known exo-planet, XO-2b, at Feb. 9th, 2008. Two consecutive high speed zipper mode data runs, lasting a total of nearly 3 hours, were collected during the observation, which is enough to cover the duration of the transit event. (Two data runs were performed because the first run terminated early due to an unknown glitch in the scheduling software.) Due to the low signal-to-noise ratio of TAOS light-c...
The star 2UCAC 47287546 (V = 11.4) was occulted by the asteroid (973) Aralia (V = 14.0, diameter = 52 km) at 14:57 on 30 December 2007 (UTC). This event was predicted by Steve Preston, and was expected to have a maximum duration around 4.9 seconds. Its shadow was expected to pass over Lulin Observatory in central Taiwan where the TAOS telescopes are located. Using high-speed [zipper mode] observations (5 Hz), the event was det...
