Description
JWST has uncovered a new population of compact objects that show a unique V-shaped SED in the UV and optical wavelength range. These so-called Little Red Dots (LRDs) often exhibit broad Balmer emission lines, indicative of the presence of AGNs. They generally lack detection of X-ray, radio, and mid-IR radiation, which is fundamentally different from typical AGNs. My team recently made significant progress with the latest JWST data. Specifically, we discovered a sample narrow-line only LRDs, a sample of LRDs with strong X-ray and radio emission, and LRDs with long-period variability, etc. These findings provide a deep insight into the nature and evolutionary path of LRDs. For example, the discovery of the LRDs with strong X-ray and radio emission suggests that at least some of LRDs will evolve into luminous AGNs at later times. I will review these findings and their implications for us to better understand LRDs.
