Аннотация:A supernova (SN) becomes as bright as a galaxy and is a powerful tool
for probing the high-redshift universe. In particular, it has been
suggested that extremely luminous SNe (M$_{R}${\lt}-21) are
detectable at z{\gt}2, which is difficult for type Ia SNe. Some luminous
SNe, such as type IIn SNe, are believed to be powered by the interaction
of the SN ejecta with the circumstellar medium. One of the interesting
features of interaction-powered SNe is the fact that they are bright in
UV. With their intrinsic brightness in UV, interaction-powered SNe could
unveil the properties of stars at high redshift and probe the primordial
universe. We performed multigroup light curve calculations of
interaction-powered SNe using the STELLA code. Based on the synthetic
multicolor light curves, we estimate the detectability of
interaction-powered SNe at high redshifts with several telescopes.
