This page maintains an up-to-date (as of October 1, 2025) compilation of high-redshift (\(z>3\)) broad-line AGN discovered and spectroscopically-confirmed with JWST. The table below includes key properties of these objects, as reported in their respective discovery papers, including their redshifts, UV magnitudes, black hole mass, and bolometric luminosity, if available. We also report whether the source would be considered a “little red dot,” following standard color/slope criteria. References are provided numerically. The table is dynamically generated in the code block below, and automatically exported to various formats for further use in analysis or publications.

              units=(None,  None, 'km/s', None, 'Msun', 'erg/s', None))

Name	Redshift	FWHM (broad)	\(\log_{10} M_{\rm BH}\)	\(\log_{10} L_{\rm bol}\)	LRD?	Reference
Test	8.50	3440.00	8.17	45.82	Y	(1)

You can copy the above python code directly into your scripts/notebooks for easy analysis. You can also find table in the following formats: TeX, FITS, ASCII. To update the compilation, please see the instructions for contribution.
