Research focus areas:
- X-ray spectroscopy of supernova remnants
- Instrument design / raytracing for sounding rockets, CubeSats, Explorer, and flagship missions
- X-ray grating fabrication and testing
- Grazing incidence mirrors
- Identification of unusual astronomical sources using machine learning
Arcus, a free-flying spacecraft featuring a high resolution X-ray spectrometer, was a Medium-class Explorer concept proposed to NASA in a recent (2016) Explorer announcement of opportunity. Arcus utilizes advancements in X-ray transmission grating technology (Critical-Angle Transmission, or CAT gratings) and cost-effective silicon pore optics (SPO), enabling it to take soft X-ray (300 - 2000 eV) spectra of astronomical point sources with unprecedented sensitivity and resolution.
Our research in this area focuses on testing high resolution, blazed X-ray reflection gratings that would enable next-generation X-ray spectrometers.
Outliers within an astronomical catalog hold the potential to offer new insights into astrophysical phenomena. Machine learning is used to identify outliers in the Chandra Source Catalog v2.0.
