Class Description:

Modern Galactic Astronomy is a course that will focus topically on a global view of the Milky Way as a galaxy and on untangling its formation history. Although just one galaxy of billions in the Universe, the singular detail with which only the Milky Way can be studied makes it the necessary stepping stone to interpret and understand observations of galaxies throughout the Universe. After we investigate and apply several approaches to mapping our Galaxy, we will question whether the picture painted by the panoply of existing Milky Way observations makes sense within the current paradigm of structure formation in the Universe. This field lies at the intersection of stellar astronomy, extragalactic astronomy, and cosmology - making Astronomy 333 an appropriate course for upper-level physics/astro students with a range of interests.

The primary goals of this class are: i) to teach you about our Galaxy, with emphasis on exciting recent developments; ii) to develop your critical thinking; and iii) to substantially prepare you to engage in physics/astronomy research. To achieve these goals, you will develop expertise in publically available tools and quantitative methods and apply these tools to a phenomenological study of the Milky Way that is similar to the modern approach that astronomers use to study the Milky Way today. The cornerstone of your work in this course will be an in-depth research project. The scope of these projects will be for each one of you to make a contribution to the Local Group and Milky Way Structure science group of the Large Synoptic Survey Telescope project (LSST).

Class Requirements:

The book is Galaxies in the Universe: an introduction (2nd edition) by Linda Sparke and John Gallagher. Errata can be found at http://www.astro.wisc.edu/~sparke/book/errata.html. We will use the material in the first half of the text. This class will focus on cutting edge results and techniques in the field of Galactic Astronomy. Consequently, much of the material is not explicitly contained in any textbook. This text will thus be supplemented by online readings and class attendance is required. You must contact me in advance if you will miss a class for any absence not owing to illness or a Dean's excuse.

We will meet in both the Observatory and in INSC H110. Unless I state otherwise in class or over email, Tuesdays will be in the Observatory and Thursdays in H110.

Astronomy 205/206 is a prerequisite. You will also be required to write some computer programs and produce computer generated figures in this class, for both problem sets and for your term project. You are permitted do this in any language with which you can achieve the necessary results. However, I will provide training and substantial support for IDL (Interactive Data Language), a high-level and user friendly language that can be used to seamlessly read, manipulate, and visualize both observational and simulated astronomical data. I will spend one class session going over Unix and IDL programming basics, and will also offer at least one tutorial outside of class for students who have no programming experience or would like a refresher.

Assignments and Grading:

35% - Homework sets; there will be about five. Although no late work will be accepted without a Dean's excuse, the lowest problem set score will be dropped, so you have one freebie.

30% - Individual research project.

15% - Class participation. This includes participation during class and coming prepared to discuss and hand in calculations that are assigned outside of the homework sets. These calculations will be graded for thoughtfulness and completeness, rather than accuracy.

20% - Final exam.

Honor Code Issues:

The important guiding principle of academic honesty is that you must never represent the work of another as your own. Please request clarification of the following if you find yourself in any doubtful situations: Discussion and collaboration with other students on homework sets and research projects is encouraged. However, all submitted work must be your own. While working together is permitted and even expected and therefore does not need to be acknowledged, merely copying the work of another student (whether a calculation or piece of computer code) without indicating that you have done so is clearly a representation of his or her work as your own and so is a violation of the code.

Accomodations:

Students who think they may need accommodations in this course because of the impact of a disability are encouraged to meet with me privately early in the semester. Students should also contact Rick Webb, Coordinator, Office of Disabilities Services (rwebb@haverford.edu, 610-896-1290) to verify their eligibility for reasonable accommodations as soon as possible. Early contact will help to avoid unnecessary inconvenience and delays.
