Peculiar objects in the birthplaces of radio pulsars -- stellar-mass black hole candidates

TL;DR

This study identifies nine potential stellar-mass black hole candidates in regions where such objects are likely to form, based on analysis of their spectral, photometric, and kinematic data, advancing the search for isolated black holes.

Contribution

The paper introduces a method for selecting black hole candidates based on their spatial distribution and properties, focusing on isolated objects in disrupted binary regions.

Findings

Nine objects identified as black hole candidates.

Candidates exhibit characteristics matching theoretical predictions.

Provides a targeted list for future observational confirmation.

Abstract

We perform a search for stellar-mass black hole candidates in the spatial regions with increased probability of their occurrence, isolated based on the evolutionary scenarios for compact objects originating in disrupted binaries. We analyze the sources located in these regions with available spectral or photometric data, as well as measured proper motions and distances. Nine objects that exhibit characteristics corresponding to theoretical predictions for isolated black holes are marked for further study as black hole candidates.
