Project Description

The MOSFIRE Deep Evolution Field (MOSDEF) survey is a large multi-year project with MOSFIRE on the 10-meter Keck I Telescope on Mauna Kea, Hawaii. With MOSDEF we observe the stellar, gaseous, metal, dust, and black hole content of ~1500 galaxies when the Universe was 1.5 to 4.5 billion years old. MOSDEF will result in more than an order of magnitude improvement over existing galaxy surveys at a similar distances.

 The MOSDEF survey is being executed in three well-studied legacy fields with deep extensive multi-wavelength datasets: AEGIS, COSMOS, and GOODS-N. Within these fields we target the regions that are covered by the CANDELS and 3D-HST surveys.

MOSDEF is a UC-wide collaboration; co-PIs include Mariska Kriek from UC Berkeley, Alice Shapley from UCLA, Naveen Reddy, Brian Siana, and Bahram Mobasher from UC Riverside, and Alison Coil from UC San Diego.
