CHARA/MIRC-X 6-telescope interferometer. I developed detector acquisition and instrument control software. Firstlight happened in July 2017.
C-RED One camera of MIRC-X uses an ultra-fast, ultra low read noise SAPHIRA near-infrared detector. It amplifies the signal from incident individual photons by the mean of avalanche gains while keeping the read noise constant.
CHARA/MIRC-X making fringes. See for more details: N. Anugu et al. 2018.
An improvement of signal-to-noise-ratio of fringes when higher avalanche gain is applied. By using this technology, the sensitivity of MIRC-X is improved by more than 2 magnitudes.
GRAVITY has been producing breakthrough results. For example, for the first time, the Einstein’s theory of gravity has been tested at a supermassive black hole by monitoring a star astrometric position. Image credit: ESO/M.Kornmesser. See press release.
