AGN optical ASAS-SN and TESS light curves

We find a set of break frequencies (<10^-2^day^-1^) from DRW and BPL fits that generally confirm previously reported correlations between break frequencies and the black hole mass. In addition, we find a second set of break frequencies at higher frequencies (>10^-2^day^-1^). We observe a potential weak correlation between the high-frequency breaks with the X-ray break frequencies and black hole mass.

We further explore the dependence of the correlations on other AGN parameters, finding that adding either X-ray, optical, or bolometric luminosity as the third correlation parameter can substantially improve the correlation significances. The newly identified high-frequency optical breaks can constrain different aspects of the physics of AGNs.
