Astrophysical Sciences and Technology
Master of science degree
An astrophysics degree that explores the depths of the universe through multidisciplinary research. Dive into an area that most interests you, whether it's general relativity, theoretical astrophysics, observational or instrumentation development, or another area related to astrophysics.
Overview
- This is a multidisciplinary program administered by the School of Physics and Astronomy, in collaboration with the School of Mathematical Sciences and the Chester F. Carlson Center for Imaging Science, setting it apart from conventional astrophysics graduate programs at traditional research universities.
- The program offers tracks in astrophysics (including observational and theoretical astrophysics), computational and gravitational astrophysics (including numerical relativity, gravitational wave astronomy), and astronomical technology (including detector and instrumentation research and development).
- Students may participate in one of three research centers associated with the School of Physics and Astronomy: the Center for Computational Relativity and Gravitation, the Center for Detectors, or the Laboratory for Multi-wavelength Astrophysics.
- Graduates of the program have secured roles at the Dudley Observatory at the Museum of Innovation & Science, the National Radio Astronomy Observatory, in higher education institutions, among others.
Students may tailor their programs of study to emphasize astrophysics (including observational and theoretical astrophysics), computational and gravitational astrophysics (including numerical relativity, gravitational wave astronomy), and astronomical technology (including detector and instrumentation research and development). Students can pursue research interests in a wide range of topics, including design and development of novel detectors, multiwavelength studies of proto-stars, active galactic nuclei and galaxy clusters, gravitational wave data analysis, and theoretical and computational modeling of astrophysical systems including galaxies and compact objects such as binary black holes. Depending on research interests, students may participate in one of three research centers: the Center for Computational Relativity and Gravitation (Video), the Center for Detectors or the Laboratory for Multi-wavelength Astrophysics.
The astrophysics degree focuses on the underlying physics of phenomena beyond the Earth, and on the development of the technologies, instruments, data analysis, and modeling techniques that will enable the next major strides in the field.
There has never been a more exciting time to study the universe beyond the confines of the Earth. A new generation of advanced ground-based and space-borne telescopes and enormous increases in computing power are enabling a golden age of astrophysics. The MS program in astrophysical sciences and technology focuses on the underlying physics of phenomena beyond the Earth, and on the development of the technologies, instruments, data analysis, and modeling techniques that will enable the next major strides in the field. The program's multidisciplinary emphasis sets it apart from conventional astrophysics graduate programs at traditional research universities.
Plan of Study
The program consists of four core courses, two to four elective courses, two semesters of graduate seminar, and a research project culminating in a thesis.
Master's Thesis
During the first year, most students begin a research project under the guidance of a faculty research advisor. Focus on the project becomes more significant during the second year after the core courses have been completed. A thesis committee is appointed by the program director and oversees the final defense of the thesis, which consists of a public oral presentation by the student, followed by a closed-door examination by the committee.
MS to Ph.D. Transfer
Students in the MS degree program who have excelled in their course work and research project may be permitted, by program approval, to transition into the doctoral degree in astrophysical sciences and technology, with the MS thesis defense serving as the Ph.D. qualifying examination. Such a transition from MS to Ph.D. is contingent on the availability of an advisor and research funding.
National Labs Career Fair
Hosted by RIT’s Office of Career Services and Cooperative Education, the National Labs Career Fair is an annual event that brings representatives to campus from the United States’ federally funded research and development labs. These national labs focus on scientific discovery, clean energy development, national security, technology advancements, and more. Students are invited to attend the career fair to network with lab professionals, learn about opportunities, and interview for co-ops, internships, research positions, and full-time employment.

Research
The astrophysical sciences and technology program offers students a wide range of research opportunities spanning observational and theoretical astrophysics, computational astrophysics, general relativity and gravitational wave astronomy and the design and development of advanced detectors and instrumentation for astronomy. RIT hosts a vibrant astronomy and astrophysics research community of more than 40 faculty, post-docs, research fellows, and graduate students who participate in three designated research centers:
- The Center for Computational Relativity and Gravitation
- The Center for Detectors
- Laboratory for Multiwavelength Astrophysics
Faculty and students frequently obtain data from space observatories including the Hubble Space Telescope, the Spitzer Space Telescope, the Chandra X-ray Observatory and the Herschel Space Observatory, and various ground-based observatories such as the twin Gemini telescopes in Hawaii and Chile, the Keck telescopes on Hawaii and the Very Large Array radio telescope in New Mexico. RIT is also a member of the LIGO Scientific Collaboration, whose goal is to analyze the data taken by the Laser Interferometer Gravitational-Wave Observatory.
Computing facilities include the GravitySimulator supercomputer, dedicated to N-body simulations of galactic nuclei and stellar clusters and the NewHorizons computer cluster, for numerical relativity and relativistic hydrodynamics simulations. Funding has recently been obtained to acquire an even more powerful 600-core cluster (BlueSky). Researchers at the Center for Computational Relativity and Gravitation also have access to national supercomputing facilities, such as the Blue Waters supercomputer at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign.
The Center for Detectors operates four research laboratories: the Rochester Imaging Detector Laboratory, the Imaging LIDAR Laboratory, the Quantum Dot Detector Laboratory, and the Wafer Probe Station Laboratory. The lab also has access to state-of-the-art machining and electronic assembly facilities on campus and advanced simulation software.
Faculty involved in the astrophysical sciences and technology program regularly attract substantial external research funding from national and state agencies (e.g., NASA, NSF, NYSTAR), amounting to over $12 million in the last four years.
Current research interests include:
- Strong-field gravitational dynamics of interacting compact objects such as black holes and neutron stars
- Magnetohydrodynamical simulations of the accretion disks and other astrophysical environments around supermassive black-holes
- Detection of gravitational wave signatures of binary black holes and/or neutron stars in close binary orbits
- Single Photon Counting Detectors for NASA Astronomy Missions
- New Infrared Detectors for Astrophysics
