GRAVITY Under Integration on Paranal

Published: 26 Aug 2015
GRAVITY beam combiner in Paranal integration lab

The VLTI 2nd generation instrument GRAVITY provides a four way beam combination facility with laser metrology for micro-arcsecond astrometry and high resolution imaging and spectroscopy in the K-band, described in Eisenhauer et al 2011. The instrument has been shipped to Paranal and is undergoing testing in the integration lab. Laboratory fringes were achieved in July 2015 and the instrument will be installed in the VLTI combined laboratory later this year. More details here.
