About

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


Abstract

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.
