1.In 2017 year in accordance with the purpose of research I continued the calculation of multicolor light curves for a number of low-metal and metal-free supernova (SN) models to provide the indicators for finding and identification of first generation and low-metallicity SNe. It was found that color evolution of the plateau phase is especially helpful for identification of zero- and low- metallicity SNe. The conclusion is that the multicolor light curves can be used to identify first generation SNe in the current and future transient surveys in case of luminous SNe. They are also suitable for identification of the low-metallicity SNe in the nearby Universe.
2.I have also calculated a set of low-metallicity massive models for superluminous supernovae in different scenarios (pair-instability supernova, magnetar, circumstellar interaction) using the same numerical technique. These successful simulations of multicolor light curves can be used for analysis of detectability of zero-metallicity supernovae at high redshifts.
3.I created numerical algorithm, that finds the best-fit model using different search criteria: multicolor light curves, evolution of photospheric velocity and temperature.
4.Several papers have been published on the research topic and the results have been presented on several international conferences and in IPMU press release.
