The NASA Hubble Fellowship Program (NHFP) supports outstanding postdoctoral scientists to pursue independent research which contributes to NASA Astrophysics, using theory, observation, experimentation, or instrumental development. The NHFP preserves the legacy of NASA’s previous postdoctoral fellowship programs. Once selected, fellows are named to one of three sub-categories corresponding to NASA’s “big questions”: How Does the Universe Work? - Einstein Fellows; How Did We Get Here? - Hubble Fellows; Are We Alone? - Sagan Fellows.
Thankful Cromartie was born and raised in Chapel Hill, North Carolina, and received her BS with highest honors in physics from the University of North Carolina at Chapel Hill. She has pursued her PhD work as a graduate student in the University of Virginia's Department of Astronomy, where she currently works under the supervision of Dr. Scott Ransom as a National Radio Astronomy Observatory Grote Reber doctoral fellow. She will be defending her PhD in April 2020.
Thankful's research focuses on using millisecond pulsar (MSP) timing to explore fundamental physics. She is a member of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) collaboration, whose goal is to detect low-frequency gravitational waves from supermassive black hole binaries with an array of precisely timed MSPs. As a graduate student, she has explored topics under the NANOGrav umbrella, including the discovery of new MSPs for inclusion in the array using the Arecibo and Green Bank radio telescopes. Thankful has also worked on constraining the poorly understood neutron star interior equation of state using pulsar-timing observations of relativistic Shapiro delay. As an Einstein fellow at Cornell, she will continue to work within NANOGrav, pursuing ambitious searches for MSPs and using the full extent of the NANOGrav dataset to further constrain the equation of state. She looks forward to conducting joint analyses of radio and Gamma/X-ray data to improve NANOGrav's sensitivity and further understand the behavior of matter at supranuclear densities.
