Going deep with UltraVISTA
Our proposal "Completing the legacy of UltraVISTA" on COSMOS has been accepted.
In the next 3 years, the VISTA telescope will image the COSMOS field (1.5 on 1.5 degrees) to its final depth in J, H, and Ks. It will finally reach equal depth across the whole field in these filters. In three years time, we will be able to reach 26, 25.7, and 25.3 AB magnitudes (5-sigma) in J, H, and Ks, respectively. This will double the area on COSMOS at this depth and will be an important step for better measurements and the identification of high redshift galaxies.
Stay tuned for the next data release!
