About
Persis S. Drell is the James and Anna Marie Spilker Professor in the School of Engineering, a professor of materials science and engineering, and a professor of physics at Stanford University. She served as the provost of Stanford University from February 1, 2017, to September 30, 2023. Prior to her appointment as provost, she was the dean of the Stanford School of Engineering from 2014 to 2017 and the director of the U.S. Department of Energy SLAC National Accelerator Laboratory from 2007 to 2012. She earned her bachelor’s degree in mathematics and physics from Wellesley College and her PhD in atomic physics from UC Berkeley. Before joining Stanford's faculty in 2002, she was a faculty member in the physics department at Cornell University for 14 years. Her research interests include experimental and observational astrophysics and cosmology, as well as experimental particle physics.

The Fermi Galactic Center GeV Excess and Implications for Dark Matter
The Astrophysical Journal · 2017-05-01 · 412 citations
articleOpen accessAbstract The region around the Galactic Center (GC) is now well established to be brighter at energies of a few GeV than what is expected from conventional models of diffuse gamma-ray emission and catalogs of known gamma-ray sources. We study the GeV excess using 6.5 yr of data from the Fermi Large Area Telescope. We characterize the uncertainty of the GC excess spectrum and morphology due to uncertainties in cosmic-ray source distributions and propagation, uncertainties in the distribution of i…
FERMI-LAT OBSERVATIONS OF HIGH-ENERGY γ-RAY EMISSION TOWARD THE GALACTIC CENTER
The Astrophysical Journal · 2016-02-26 · 408 citations
articleOpen accessABSTRACT The Fermi Large Area Telescope (LAT) has provided the most detailed view to date of the emission toward the Galactic center (GC) in high-energy γ -rays. This paper describes the analysis of data taken during the first 62 months of the mission in the energy range 1–100 GeV from a 15° × 15° region about the direction of the GC. Specialized interstellar emission models (IEMs) are constructed to enable the separation of the γ -ray emissions produced by cosmic ray particles interacting with…
3FHL: The Third Catalog of Hard Fermi-LAT Sources
The Astrophysical Journal Supplement Series · 2017-09-27 · 368 citations
articleOpen accessAbstract We present a catalog of sources detected above 10 GeV by the Fermi Large Area Telescope (LAT) in the first 7 years of data using the Pass 8 event-level analysis. This is the Third Catalog of Hard Fermi -LAT Sources (3FHL), containing 1556 objects characterized in the 10 GeV–2 TeV energy range. The sensitivity and angular resolution are improved by factors of 3 and 2 relative to the previous LAT catalog at the same energies (1FHL). The vast majority of detected sources (79%) are associat…
THE FIRST FERMI LAT SUPERNOVA REMNANT CATALOG
The Astrophysical Journal Supplement Series · 2016-05-01 · 258 citations
articleOpen accessABSTRACT To uniformly determine the properties of supernova remnants (SNRs) at high energies, we have developed the first systematic survey at energies from 1 to 100 GeV using data from the Fermi Large Area Telescope (LAT). Based on the spatial overlap of sources detected at GeV energies with SNRs known from radio surveys, we classify 30 sources as likely GeV SNRs. We also report 14 marginal associations and 245 flux upper limits. A mock catalog in which the positions of known remnants are scram…
The Astrophysical Journal Letters · 2016-06-14 · 256 citations
articleOpen accessABSTRACT On 2015 June 16, Fermi -LAT observed a giant outburst from the flat spectrum radio quasar 3C 279 with a peak >100 MeV flux of ∼3.6 × 10 −5 photons cm −2 s −1 , averaged over orbital period intervals. It is historically the highest γ -ray flux observed from the source, including past EGRET observations, with the γ -ray isotropic luminosity reaching ∼10 49 erg s −1 . During the outburst, the Fermi spacecraft, which has an orbital period of 95.4 minutes, was operated in a special pointi…
