Christopher Reynolds

Christopher Reynolds is a Professor of Astronomy at the University of Maryland, College Park (UMD), and Director of the UMD/NASA-GSFC Joint Space Science Institute (JSI). He leads the Advanced X-ray Imaging Satellite (AXIS) project and has held roles including Plumian Professor of Astronomy at the University of Cambridge (2017-2023) and Deputy Director of its Institute of Astronomy (2018-2022). His research focuses on theoretical and observational high-energy astrophysics, particularly supermassive black holes and plasma physics in galaxies/galaxy clusters using X-ray observatories like Chandra and XMM-Newton. Recent activities include teaching ASTR422 Cosmology (Fall 2025) and publishing impactful studies on accretion disk magnetism and intracluster plasma dynamics.

Research Interests:

• Black hole accretion flow dynamics
• X-ray observations of galactic clusters
• Magnetohydrodynamics in astrophysical plasmas

Publications highlight trends in understanding plasma behavior in extreme environments, supported by observational data and advanced theoretical models. Current projects include the AXIS mission, advancing X-ray imaging capabilities. Reynolds has been recognized through events like the 2024 McDonnell Distinguished Lectures at Washington University.

Advising & Grants: Principal Investigator for AXIS, with grants supporting observational and computational astrophysics. Active in mentoring postdoctoral researchers and graduate students through his UMD research group.

Labs/Teams: Leads the Reynolds Research Group at UMD, collaborating with NASA-GSFC and international observatories to explore cosmic phenomena through interdisciplinary approaches.
