Abstract

A statistical analysis of survey observations conducted by the global network of MASTER robotic telescopes over 20 years has been used to derive independent constraints on the optical emission associated with Fast Radio Bursts (FRBs). The method is based on simulating a synthetic catalog of FRBs uniformly distributed across the sky and in time and subsequently checking for the absence of random coincidences with optical observations. As a result, a constraint on the ratio of the burst energy in the optical band to the energy in the radio band has been obtained: \(\eta < 4.5 \times {{10}^{4}}\) . Although this limit is less strict than that provided by the Gaia mission, it offers an independent test for FRB origin models and is less dependent on assumptions about the duration of the optical signal. The results place important constraints on theoretical models that predict significant optical emission from FRBs.
