# JWST上天后高红移宇宙最有意思的发现之一

==观测特征==
* compact morphology： majority of LRDs are not hosted by well-established, massive galaxies; instead, their nuclear BHs appear to be overmassive relative to the local BH-to-galaxy mass correlation,
*UV-optical spectral energy distributions (SEDs) with a turnover wavelength around rest-frame ≃ 4000  ̊A, their broad-line emission properties, and the weakness in canonical AGN signatures such as hot dust and X-ray corona emission.
*However, deep JWST/MIRI and ALMA observations show no significant detection of reprocessed IR flux in LRDs
*To date, the JWST observational programs have not been originally designed for multi-epoch observations and make the detection of variability challenging.
