PhD in Astrophysical Sciences - Galactic and Extragalactic Astronomy in Princeton United States | Princeton University

Modern observatories operate across a broad spectrum of wavelengths, while extensive survey data merges with cutting-edge theoretical and modeling breakthroughs to help us build a complete understanding of galaxy formation, evolution, and current traits. The department's observational research in this field has primarily been conducted through large-scale surveys. We've taken a leading position in the Sloan Digital Sky Survey (link is external), utilizing its findings to examine and define galaxy characteristics and their cosmic surroundings in today's universe (Greene, Gunn, Lupton, Strauss). This involves analyzing photometric and spectroscopic data as well as weak gravitational lensing to estimate galactic masses. Additionally, we're employing information from the Hyper Suprime-Cam Subaru Strategic Program (link is external) to investigate galaxy properties and development, while Subaru Prime Focus Spectrograph spectroscopy will enable precise redshift measurements and detailed physical property analysis. Galaxy clusters serve both as remarkable astrophysical testbeds and valuable cosmological tools (Bahcall, Gunn, Strauss). The universe's most massive galaxies offer crucial insights into galactic evolution, with the MASSIVE survey specifically examining their supermassive black holes, dark matter halos, and star populations (Greene).
