Connecting the Dots: UV-bright Companions of Little Red Dots as Lyman–Werner Sources Enabling Direct-collapse Black Hole Formation

We compile a sample of 83 little red dots (LRDs) with JWST imaging and find that a substantial fraction (∼43%, rising to ≳80% for the most luminous LRDs) host one or more spatially offset, UV-bright companions at projected separations of 0.5 kpc ≲ d  ≲ 5 kpc, with median 〈 d 〉 = 1.0 kpc. This fracti...
