MATH-231
Differential Equations
3 Credits
This course is an introduction to the study of ordinary differential equations and their applications. Topics include solutions to first order equations and linear second order equations, method of undetermined coefficients, variation of parameters, linear independence and the Wronskian, vibrating systems, and Laplace transforms.
ASTP-790
Research & Thesis
1 - 3 Credits
Masters-level research by the candidate on an appropriate topic as arranged between the candidate and the research advisor.
PHYS-498
Advanced Physics Independent Study
1 - 3 Credits
This course is a faculty-directed tutorial of appropriate topics that are not part of the formal curriculum. The level of study is appropriate for student in their final two years of study.
MATH-411
Numerical Analysis
3 Credits
This course covers numerical techniques for the solution of nonlinear equations, interpolation, differentiation, integration, and the solution of initial value problems.
ASTP-890
Research & Thesis
1 - 6 Credits
Dissertation research by the candidate for an appropriate topic as arranged between the candidate and the research advisor.
ASTP-608
Fundamental Astrophysics I
3 Credits
This course will provide a basic introduction to modern astrophysics, including the topics of radiation fields and matter, star formation and evolution, and stellar structure. This course will provide the physical background needed to interpret both observations and theoretical models in stellar astrophysics and prepare students for more advanced topics and research in astrophysics.

NSF funds RIT researchers to develop code for astrophysics and gravitational wave calculations
The National Science Foundation recently awarded researchers at RIT, the University of Illinois at Urbana-Champaign, Louisiana State University, Georgia Tech and West Virginia University grants totaling more than $2.3 million to support further development of the Einstein Toolkit, a community-developed code for simulating the collisions of black holes and neutron stars, as well as supernovas and cosmology.
