资源简介:

I compiled 1,034 JWST-selected Little Red Dots (LRDs) and performed archival Chandra ACIS forced photometry for the 827 with coverage. The blind pipeline recovered three literature-known Chandra-detected LRDs (3DHST-AEGIS-12014, PRIMER-COS 3866, and JADES 21925) and found no additional individually detected LRDs. UHZ-1 was included separately as a literature-known targeted Chandra detection of a high-redshift compact red source, but was not independently rederived here. Two apparent candidates, K24-73890 and B24-193912, failed counterpart scrutiny after NED queries at the X-ray catalog positions identified lower-redshift galaxies. These cases show that CSC-level astrometric agreement is insufficient for LRD/X-ray association in deep fields. The literature-known X-ray-source incidence in the Chandra-covered compilation is 4/827 = 0.48% (95% binomial CI 0.13%-1.23%), or 4/1,034 = 0.39% in the parent sample.
