First Mover Research Group
Korea Astronomy and Space Science Institute has initiated the FMRG Program in 2015 for the promotion of research groups which are aiming to perform pionneering research of world-class level. CosKASI was appointed as the first FMRG in 2015, and be awarded with the total $6M research support for 9 years from 2015 to 2022.
Participation in DESI (Dark Energy Spectrocopy Instrument)
The Dark Energy Spectroscopic Instrument (DESI) will measure the effect of dark energy on the expansion of the universe. It will obtain optical spectra for tens of millions of galaxies and quasars, constructing a 3-dimensional map spanning the nearby universe to 10 billion light years.
DESI will be conducted on the Mayall 4-meter telescope at Kitt Peak National Observatory starting in 2018. DESI is supported by the Department of Energy Office of Science to perform this Stage IV dark energy measurement using baryon acoustic oscillations and other techniques that rely on spectroscopic measurements.
Cosmology group at KASI plans to take part in DESI as an associated member institute. We provide an apportunity for young researchers to meet challenges for next decades.
