Deep Subaru HSC z-band imaging of the Euclid/JWST/Roman Deep Field

Subaru/HSC | 2N | PI - N. Suzuki

We request 2 nights of Subaru Hyper-SuprimeCam to complete z-band observations of the largest multi-wavelength (ugriz) field, Hawaii Two-0 (H20), a contiguous survey covering 20 sq. deg area of two primary Euclid Deep Calibration Fields (NEP and CDFS). A total of 30 nights on the Subaru/HSC and 10 nights on the Keck/DEIMOS telescopes were allocated for this program through the Hawaii TAC which has now completed g-, r-, i- band coverage. This proposal is to complete the z-band photometric survey in the NEP field to the desired depth of 26.5 AB. The z-band data are essential for accurate physical parameter measurements of galaxies at 0 < z < 3 (e.g., photometric redshift and stellar mass) and selection of galaxies at 3 < z < 6 . These measurements will allow us to study the evolution of massive galaxies to z~6, estimate the properties of their dark matter haloes through clustering measurements, and find rare objects that are re-ionizing the universe. This is a legacy Euclid program.

My research interests lie almost exclusively within the realm of extragalactic astrophysics and cosmology. I use state-of-the-art optical and infrared observatories and surveys to study the lives of galaxies, and how their properties change over cosmic time. This includes detailed case studies of individual galaxies, as well as statistical analyses of large survey catalogs.
