AVAST Survey 0.4-1.0 μm Spectroscopy of Igneous Asteroids in the Inner and Middle Main Belt

Posted by klaurent Chicago

Kavli Affiliate: Geza Gyuk | Summary:We present the spectra of 60 asteroids, including 47 V-types observed during the first phase of the Adler V-Type Asteroid (AVAST) Survey. SDSS photometry was used to select candidate V-type asteroids for follow up by nature of their very blue $i-z$ color. 47 of the 61 observed candidates were positively […]

Reduction of thermal fluctuations in a cryogenic laser interferometric gravitational wave detector

Posted by klaurent Tokyo

Kavli Affiliate: Tomiyoshi Haruyama | Summary:The thermal fluctuation of mirror surfaces is the fundamental limitation for interferometric gravitational wave (GW) detectors. Here, we experimentally demonstrate for the first time a reduction in a mirror’s thermal fluctuation in a GW detector with sapphire mirrors from the Cryogenic Laser Interferometer Observatory at 17,K and 18,K. The detector […]
