We are performing a flux limited transient survey based on the MSIP all sky survey. The standard in this field is set by ASAS-SN which is by our estimate complete to less than 17 mag. The experimental goal of the ZTF RCF project is to classify transients (which are mostly SNe) to a peak magnitude, m_p of about 18.5 mag. In practice, this means classifying transients which are a few tenths mag fainter (~18.75). Flux limited surveys serve many purposes, and are essential for e.g., computing rates. We have a specific novel goal: use SN of type Ia to evaluate the red-shift completeness factor (RCF) of catalog(s) of nearby (<200 Mpc). [ http://adsabs.harvard.edu/abs/2017arXiv171004223K

Cosmology with Type II-P distances: Expanding photosphere method

Leads: Jakob Nordin, Peter Nugent, Sarafina Nance, Suhail Dhawan, Ariel Goobar

Brief Description: Type II-P supernovae using the expanding photosphere method give absolute distances, independent of the Cepheid distance ladder, hence, are a novel probe to resolve the cause of the Hubble tension. This project has two related motivations. Firstly, for SN II-Ps that exploded in galaxies with an SN Ia, the II-P distance can be used to calibrate the absolute luminosity of (nearby, z < 0.03) Type Ia supernovae and hence, measure H0. Secondly, SNII-P's can themselves be used to make a Hubble diagram extending the redshift range to z ~ 0.07. Since the largest degeneracy in measuring the distance is a precise explosion date, the ZTF sample with early coverage would be ideal for this study.

Observations: P48 g,r,i lightcurves, SEDm spectra for nearby Type II-Ps, Gemini/8-m class for SNe 19.5 mag and fainter
