Abstract: We propose searching for isolated stellar-mass black hole (BH) candidates based on the fact that more than 50% of radio pulsars have originated in binary systems, now disrupted, where the other component could have evolved into a BH prior to the second supernova event of the system, which caused its disruption. We selected isolated radio pulsars with known parallaxes and relatively small characteristic ages that fit our criteria and traced their trajectories back to their presumed birth locations. These locations were then analyzed for possible BH candidates based on positional, photometric, and spectral data available in the online catalogs. We use the example of 4 pulsars from our sample, J0139+5814, J0922+0638, J0358+5413, and J1935+1616, to demonstrate the proposed method, and present the first results: 22 candidates were selected for further analysis.
