Graduate Masters Theses
We present a multi-epoch analysis of the X-ray spectrum of NGC 1052, a nearby galaxy notorious for its well-studied spectral variability. We utilize observations from NuSTAR, XMM-Newton, Chandra, Swift, Suzaku, BeppoSAX, and ASCA to create a comprehensive set of data that spans roughly 20 years. Organizing our data by observation date and grouping into specific epochs allows us to explore a model allowed to flex and accommodate any spectral changes that occur over time in the X-ray spectrum of NGC 1052. We find that the spectrum takes on a relatively flat nature and is best modeled with two neutral absorption …
