PURPOSE OF COURSE:
To introduce students to open questions in astrophysics and current research and observational efforts to address these questions. The students will become familiar with research areas that will help them keep track of new developments and, for majors, select the most relevant research topics in the future.
TOPICS COVERED: Today's astrophysics largely focuses on extreme cosmic processes whose observations recently became available due to modern, large-scale facilities such as the LIGO gravitational wave observatory, the Large Synoptic Survey Telescope, or the IceCube Neutrino Observatory. The course will focus on (i) compact objects such as black holes and neutron stars, (ii) emission processes by these objects, as well as (iii) relevant modern observational strategies and observatories. Topics include core-collapse supernovae, astrophysical particle acceleration, gamma-ray bursts, gravitational-wave emission, kilonovae, and multimessenger observations.
COURSE GOALS AND OBJECTIVES:
The course will give you an understanding of some of the main, actively researched topics in astrophysics. It will give you an understanding of the frontiers, where the field is going, as well as some of the modern observational tools. Additionally, the course's objective is to prepare you for absorbing and communicating scientific work as researchers encounter it.
GRADING: The final grade will be based on classroom participation (30%), homework (30%) and a final presentation on an agreed-upon topic relevant to the course material (40%).

DISCLAIMER: This syllabus represents the Prof. Bartos' current plans and objectives. As we go through the semester, those plans may need to change to enhance the class learning opportunity. Such changes, communicated clearly, are not unusual and should be expected.
