The GOODS-South Field: Variability Survey
For my second-year project, I completed a study aimed at identifying Active Galactic Nuclei (AGN) in the GOODS-South Field. Using pre-existing infrared and X-ray catalogs, I performed optical photometry to search for significant variability that might indicate the presence of an AGN.
My advisor and I published this work in the Astrophysical Journal (Klesman & Sarajedini, 2007). The astro-ph preprint can be found here:
Optical Variability of Infrared Power Law-Selected Galaxies & X-ray Sources in the GOODS South Field
Study of AGN in Galaxy Clusters
My thesis project aims to study AGN in galaxy clusters via multiwavelength detection. I am currently exploring at the overlap between optical variability and other detection methods such as X-ray point source mapping and infrared power-law SED behavior. I have a number of intermediate-redshift galaxy cluster targets with multiple ACS epochs as well as X-ray and IR coverage, and am currently completing a survey of these fields for AGN using the multiwavelength approach outlined above.
