Title: | WISE Overview |
Topic: | Discoveries |
Abstract: | WISE launched one 14 Dec 2014 and surveyed the entire sky in 4 bands from about 7 Jan 2010 to 6 Aug 2014. It continued to survey in 3 bands until 30 Sep 2014, and then continued the NEOWISE asteroid program in two bands until 1 Feb 2011. After a 2.5 year hiatus, NEOWISE was restarted, and after passively cooling down to below 74 K, observations restarted in mid-Dec 2013. The fifth coverage of the sky is now underway, although some parts of the sky have already been covered 6 times. WISE set out to get radiometric diameters on many asteroids, and observed about 160,000 asteroids. The NEO albedo distribution is distinctly bimodal, with 25% of the NEOs in a dark population peaking at 3% p_V. WISE set out to find the closest stars, and WISE data has been used to find brown dwarfs 2 and 2.3 pc from the Sun. WISE set out to find the most luminous galaxies in the Universe, and has found hot dust-obscured galaxies with luminosities over 10^14 Suns. The ongoing NEOWISE observations can greatly improve both variability and proper motion studies, and also improve the selection of normal galaxies near z=1. |
