This seminar generally will meet from 2:30-5:00 P.M. on Mondays in the Pratt Conference room at the Observatory (60 Garden Street, up near the Radcliffe Quad). Occasionally we may meet at other locations depending on time and schedule --- warning, I may have to go to telescopes in stange places at strange times, one of the hazards of being an observational astronomer! The first offical meeting of this seminar for the spring of 2010/11 will be on Wednesday, September 1st, at 2:30 P.M. also in the Pratt Conference Room (a.k.a. Observatory PG04). Note the special first meeting date on the first day of classes. Directions to the Observatory and to the Pratt Conference Room can be found here: Observatory/Pratt Directions.
PROF. JOHN P. HUCHRA will offer a seminar on Galaxies and the Universe. The seminar will offer and introduction to the study of galaxies and cosmology and will discuss the interplay between observation and theory as well as our ability to view the universe. We will discuss the scientific method and the rise of our modern cosmological models. Topics covered will include the internal structure and dynamics of galaxies, cosmological models, the determination of the cosmic distance scale, observations of large-scale structure in the universe, quasars, galaxy formation, and the age, size, and fate of the universe. We will explore the basic observations that lend support to the current cosmological model, the inflationary hot Big Bang, and we shall discuss the recent observations that indicate that the Universe might even be speeding up. Readings will be taken from current popular articles and texts. Students will participate in a small research project using electronic images of galaxies or catalogs of galaxy properties to measure simple properties of galaxies and clusters of galaxies. We'll also try to do some observing with Harvard's local telescopes. Attendees of this seminar should have some mathematical background.
The seminar will use Stephen Phillipps' book The Structure & Evolution of Galaxies. I suggest purchasing a copy either at the COOP or from one of the discount textbook websites noted on my main website.
Readings will be taken from the assigned text, from Scientific American, from introductory and popular texts and from other current popular articles. It is especially important for students to keep up with the New York Times Tuesday's Science Times. Students will participate in small research projects using a variety of datasets and images of galaxies or catalogs of galaxy properties to measure simple properties of galaxies and clusters of galaxies. We'll also try to do some observing with Harvard's local telescopes.
Considerable information on modern cosmology can also be found on the web. A good starter site is NASA's:
The goals of this seminar are to acquaint students with
(1) What galaxies are,
(2) What observational astrophysics is,
(3) What the current cosmological model is, and
(4) How observations of galaxies are used both to ``measure'' the universe and to test cosmological theories.
The seminar is intended to give students a general overview of extragalactic astronomy with particular emphasis on the concept of using observations (experiments) to test and constrain theories. In the course of the seminar, we will cover some basic physical concepts such as the Virial Theorem and gravitational binding energy, we will discuss the concept of infinity and we will touch on black holes and quasars. This is an astronomical introduction to the scientific method.
The first few discussions will center on the philosophy of astronomical observations (as opposed to laboratory experimentation), and discussions of what exactly galaxies are and why they are important in both the study of humankind's place in the universe and our study {\it of} the universe including simple cosmological theories. Discussions during the middle of the term will cover current observational work on the measurement of the cosmic distance scale, the mass density of the universe, the rate at which the universe is slowing down and the age of the universe. The seminar will close with discussions of advanced topics such as galaxy formation, large scale structure in the universe, and the eventual fate of the universe.
Near the middle of the term, you wil be given small projects to work on, primarily involving computers to analyse data on galaxies. These will include using software packages to determine surface brightness and color profiles for galaxies from digital images and to study the dynamical properties of a few clusters of galaxies to determine their masses. The students will do these in groups of 3 or 4 with the aid of the instructor.
Reading assignments will be made each week, usually from the assigned books or from popular (Scientific American level) articles. Students will (weather permitting) do some observing at either the Science Center or Harvard ollege Observatory. I also will invite guests from the CfA staff who have special interests in the topics covered.
The seminar requirements will be attendance and class participation, a writeup of the research projects, and a final short essay on one of the general topics covered in the seminar. Most of the books and materials needed for this seminar are easily available at the Harvard COOP or on Amazon.com.

Various Utilities are available for use for the seminar, including a routine called ``getimage'' which will allow you to created images of galaxies from the POSS image server using the IDL routine "makeps" to make postscript files, and the Supermongo package, for making plots.
