PhD in Astronomy and Astrophysics in University Park United States | Pennsylvania State University

The Astronomy and Astrophysics graduate program equips students for professional paths in space science, astronomy, and education. Students can engage in graduate studies and research across theoretical, observational, and instrumental astronomy and astrophysics. Key theoretical research focuses on high-energy astrophysics (covering neutron stars, black holes, and gamma-ray bursts), cosmology and relativity, planetary formation, stellar dynamics, and computational techniques. Observational research encompasses spectroscopic and photometric analysis of distant quasars, galaxies, and intergalactic matter, gamma-ray bursts, X-ray and optical studies of quasars and active galaxies, visible light examination of nearby galaxies and their stars, infrared investigation of protoplanetary disks and brown dwarfs, as well as spectroscopic detection of planetary systems. Instrumental research involves creating X-ray telescopes and detectors, along with high-precision optical and near-infrared spectrographs. Faculty collaborate with university-wide initiatives such as the Astrobiology Research Center, Center for Astrostatistics, Center for Exoplanets and Habitable Worlds, and the Institute for Gravitation and the Cosmos.
