Physics 798G – Spring 2007

Special Topics in Experimental Gravitation and Astrophysics

 

Instructor:            Professor Ho Jung Paik

                        Room 4204B Physics, Phone: 301-405-6086, E-mail: hpaik@umd.edu

                        Office hours:  Tu Th 1:00 - 2:00 p.m. or by appointment.                

Description:      General Relativity and the Standard Model of particle physics, which constitute the core of our understanding of the universe, are challenged by observation and the need to unify them.  We review the progress being made in Experimental Gravitation and Astrophysics.  We review tests of Newton’s law and the Equivalence Principle and searches for spin-mass coupling, which all represent searches for new interactions and dark matter particles.  We also discuss the experimental techniques and astrophysical significance of gravitational wave detection, and survey astrophysical observations in microwave, x-ray, and gamma-ray bands.  Some of the topics covered are research projects being carried out at the University of Maryland.  External lecturers will be invited to cover specialized topics. 

Prerequisite:      Knowledge of General Relativity is not required.  Any first or second year graduate student should be able to take this course.  (There will be no textbook.) 

Lectures:          Tu Th 11:00-12:15 (Room 1201, Physics).

Reports:           There will be no exams but there will be some reading assignments and quizzes.  Students will be assigned to prepare and submit a written report on a topic chosen from a variety of topics suggested.  Each student will also be required to make a short presentation based on his or her report at the end of the semester.

Grading:           Your course grade will be based on the following percentages:

                        Attendance/participation: 25% Quizzes: 25%              

Written report:  25%                             Presentation: 25%
