Mining current optical and infrared databases to find variable active galactic nuclei.


Continuum reverberation mapping (CRM) can be used to measure physical distances in AGN accretion disks. There have been a limited number of studies conducted which measured the continuum reverberation of Type 1 Seyfert galaxies due to a limited number of continuous observations in both the optical and infrared (IR). The goal of this project is to mine data from multiple surveys including: Near Earth Objects Wide-field Infrared Survey Explorer (NEOWISE),Transiting Exoplanet Survey Satellite (TESS), All Sky Automated Survey for SuperNovae (ASAS-SN), Zwicky Transient Facility (ZTF) and the Catalina Sky Survey to find regions of sky that have a maximum amount of observational overlap in the infrared and optical. Once the areas with high temporal coverage are identified, we will look for known Type 1 Seyfert galaxies in those areas and analyze their light curves at multiple wavelengths to determine the time delay between the optical emission to the infrared emission from 0.445 μm - 4.6 μm. This will be used to determine the distance between the optical emitting region and the infrared emitting region.
