TL;DR: In this article, the authors obtained a limiting flux of F_opt < 1.6 x 10−14 ergs/s/cm^2 in the wavelength range 2900-9650 Angstroms for any continuum emitter at the center of the supernova remnant (SNR).

Pulsar wind nebulae: theoretical aspects and observational constraints
TL;DR: In this paper, the authors identify the pulsar wind nebulae 3C 58 and MSH 15-52 as good candidates for being in the early stage of evolution where the wind nebula is interacting with the freely expanding supernova ejecta.
