The theory of gravitational lensing (GL) is one of the three fundamental observational consequences of Einstein’s theory of general relativity. GL describes how rays of light are bend by massive astronomical objects like stars, galaxies and galaxy clusters. This results in magnification and potentially in multiple images of lensed sources.
The unique consequences of GL have been instrumental and of growing importance in modern astronomy. Laying out the theoretical framework of GL, and through seminar sessions developing and strengthening the student’s “astronomer skill set”, this course will focus on recent studies enabled by GL and explore scientific applications, where GL plays a crucial role. These include galaxy (cluster) mass determination, study of low-mass galaxies in the early Universe, determining the expansion rate of the Universe, and detecting planets around other stars.
The weekly seminars will focus on developing “astronomer skill sets”, which will introduce and explore tasks and tools used on a daily to weekly basis by most astronomers. This includes text review, problem solving, scientific outreach preparation, presentation skills, etc.
Hence, this course provides a broad overview of gravitaional lensing from both the observational and theoretical side, and help develop personal skills for general use in astronomy.
