Evan Scannapieco is an astrophysicist and professor in the School of Earth and Space Exploration at Arizona State University.[1] His research uses numerical simulations and observations to study galaxy evolution, star formation, supernovae, active black holes, fluid dynamics, and the cosmological evolution of gas and heavy elements.[1][2]

Education

edit

Scannapieco received an A.B. in physics from Harvard University and an M.S. and Ph.D. in physics from the University of California, Berkeley.[1]

Career

edit

After completing his doctorate, Scannapieco received an NSF MPS Distinguished International Postdoctoral Research Fellowship for research at the Arcetri Observatory in Italy and the Institut d'Astrophysique de Paris in France.[3]

Scannapieco is a professor at Arizona State University in the School of Earth and Space Exploration.[1] From 2018 to 2022, he served at NASA Headquarters in the Astrophysics Division. His NASA roles included program manager for the Astrophysics Theory Program, Astrophysics Lead for the FINESST program, Astrophysics Program Manager for a NASA artificial-intelligence and machine-learning task force, and Project Scientist for the Neil Gehrels Swift Observatory.[1][4][5][6]

Research

edit

Scannapieco's early research examined how galactic winds and supernova-driven outflows enriched the intergalactic medium and affected later galaxy formation. He modeled the heating, metal enrichment, and baryonic stripping produced by high-redshift outflows, arguing that such feedback could suppress dwarf-galaxy formation and produce an inhomogeneous distribution of metals in the intergalactic medium.[7][8][9]

He later developed related models and observational tests for the clustering and sources of intergalactic metals, and studied enrichment signatures of the first stars and Population III objects.[10][11][12]

In 2004, with S. Peng Oh, Scannapieco modeled quasar feedback and its possible role in heating gas around massive galaxies and suppressing star formation.[13] In 2006, with Robert J. Thacker and H. M. P. Couchman, he extended this work into cosmological hydrodynamic simulations of quasar outflows.[14]

Scannapieco has also published on double-degenerate white dwarf collisions as possible Type Ia supernova progenitors.[15] His work includes studies of mixing in compressible turbulence, nebular emission-line diagnostics, and density fluctuations in supersonic turbulence.[16][17][18]

In 2026, Scannapieco was among the authors of a Physical Review D study on intergalactic magnetic-field growth driven by reionization-era turbulence.[19] He was also among the authors of an XRISM collaboration study of a fast, hot wind from the starburst galaxy M82, published in Nature in 2026.[20][21]

NASA and program leadership

edit

At NASA Headquarters, Scannapieco served as program scientist for the Astrophysics Theory Program, and introduced dual-anonymous peer review to the program.[5]

Scannapieco also served as Project Scientist for the Neil Gehrels Swift Observatory,[6] a NASA multi-wavelength observatory built for gamma-ray bursts and other transient phenomena, with instruments observing gamma-ray, X-ray, ultraviolet, and optical wavebands.[22]

Scannapieco was also the Astrophysics program scientist for the Future Investigators in NASA Earth and Space Science and Technology (FINESST) program during the introduction in 2019.[4] FINESST solicits proposals for graduate student-designed and performed research projects relevant to NASA's Science Mission Directorate[23] and it replaced the formed NASA Earth and Space Science Fellowship program.[24]

NASA Astrophysics Division materials from 2021 identify Scannapieco with Astrophysics Division initiatives related to inclusion, proposal processes, and dual-anonymous peer review.[25] His ASU profile also lists his NASA service as including leadership of a NASA artificial-intelligence and machine-learning.[1]

Service and community building

edit

Scannapieco served as faculty in the Joint Institute for Nuclear Astrophysics,[26] an interdisciplinary nuclear astrophysics network whose core institutions have included Michigan State University, the University of Notre Dame, Arizona State University, and the University of Washington.[27]

He also served as principal investigator of the NSF International Research Experiences for Students award "Measuring Cosmic Magnetism with the Low Frequency Radio Array," which supported a collaboration between Arizona State University and the German Long Wavelength Consortium and funded graduate and undergraduate research using LOFAR, a low-frequency radio telescope network operating across Europe.[28] [29]

In 2023, NASA selected Scannapieco and ASU colleague Evgenya Shkolnik to serve on the Science, Technology, Architecture Review Team for the Habitable Worlds Observatory,[30] a future flagship astrophysics mission after the Nancy Grace Roman Space Telescope.[31]

Awards and honors

edit

In 2025, Scannapieco shared the First Prize of the Buchalter Cosmology Prize with Christopher Cain, Matthew McQuinn, Anson D'Aloisio, and Hy Trac for work on magnetic-field growth driven by reionization-era turbulence.[32][19]

Scannapieco's is was also the recepient of NASA Headquarters Honor Awards in 2019 and 2021 and the Dr. Manuel Servín Faculty Award at Arizona State University in 2019.[1]
