The UltraVISTA Supernova Survey

I will present the UltraVISTA supernova survey, a near-infrared (YJHKs) time-domain survey built upon the high-cadence observations and excellent image quality of the UltraVISTA survey (from 2009 to 2016). The survey covers ~ 1.4 square degrees in the COSMOS field, and the observations were performed with a mean cadence of 3 to 6 days in the deep region (0.7 square degrees) and 1 to 3 days in the ultra-deep region (0.7 square degrees), reaching a magnitude limit of 22.5 mag to 24 mag, depending of the bandpass. We have discovered more than 100 supernova candidates of all classes at a wide range of redshifts and we will present YJHKs photometry of several of them, including early discovered and well-observed super-luminous SNe. In particular, we will discuss the advantages of doing a near-infrared wide field search of type Ia and super-luminous SNe. The near-infrared is a wavelength region particularly sensible to search for neutron star mergers and black-hole neutron star mergers, I will present our detection limits and our rate estimate based on our wide and deep near-infrared survey. I will also discuss the benefits of doing a wide and deep NIR kilonova search.
