ASAS-SN Supernova follow-up photometry

The University of Iowa performs follow-up multi-color photometry of candidate supernovae discovered by the ASAS-SN project. The photometric light curves help constrain the type and detailed physics of the supernovae. 

Several refereed publication and preprints include Iowa Gemini photometry of ASAS-SN targets:

Bose et al. 2017, Gaia17biu/SN 2017egm in NGC 3191: the closest hydrogen-poor superluminous supernova to date is in a "normal", massive, metal-rich spiral galaxy

Pastorello, et al. 2017, Supernovae 2016bdu and 2005gl, and their link with SN 2009ip-like transients: another piece of the puzzle

A sample photometric 2-color light curve, of the Type Ia supernova SN 2017cts = ASASSN-17em, was observed using the Gemini telescope over several weeks, is shown below. It is located in a faint galaxy at z = 0.109 (82 Mpc).
