Congratulations to Hannah Marlowe for successfully defending her PhD dissertation on "Polarimetric and Spectrographic Instrumentation to Enable Next Generation X-ray Observatories."

"Hannah’s thesis investigates instrumentation designed for scientific inquiries in X-ray polarimetry and spectroscopy. She studied the spectral evolution of an Ultraluminous X-ray source, IC 342 X-1 using a suite of observatories across the electromagnetic range. She also performed an in depth analysis on the polarization sensitivity of off-plane reflection gratings. For the first time, she definitively demonstrated the absence of polarization sensitivity, contrary to previous theoretical expectations and measurements."
