Deep Optical Imaging of the COSMOS Field with Hyper Suprime-Cam Using Data from the Subaru Strategic Program and the University of Hawaii

Understand

We present the deepest optical images of the COSMOS field based on a joint dataset taken with Hyper Suprime-Cam (HSC) by the HSC Subaru Strategic Program (SSP) team and the University of Hawaii (UH).

• The COSMOS field is one of the key extragalactic fields with a wealth of deep, multi-wavelength data.
• However, the current optical data are not sufficiently deep to match with, e.g., the UltraVista data in the near-infrared.
• The SSP team and UH have joined forces to produce very deep optical images of the COSMOS field by combining data from both teams.
