Course Description and Goals: Astronomy 271 is a general astronomy survey course at a greater level of detail than is covered in Astronomy 101. ASTR 270 and 271 are also the first required ASTR classes for BS Astrophysics majors. ASTR 271 is also required for the BA in Physics and Astrophysics. During this spring semester (part 2 of the 2 part series of Astronomy 270/271) we will learn about stars, our own Milky Way Galaxy, other galaxies and everything else in the Universe. This course will describe the nature of the Universe starting with stars and working up through star clusters, galaxies, clusters of galaxies and superclusters. Black holes, pulsars, supernovae, dark matter, the expanding Universe and other fascinating astronomical topics will also be explored. We will use math and physics as we explore the Universe. We will also discuss the methods and observations on which our understanding is based. All students are welcome in this class regardless of citizenship, immigration status, or sexual orientation.
Pre-Requisites: Math 150 or 162. Physics 151 or higher.
We will learn some physics concepts and make
use of high-school level algebra and trigonometry, but will
not use calculus.

The Lab (A271L): There is a night laboratory which accompanies this class, where you learn about the night sky, and get your hands on real telescopes. It meets at the Campus Observatory, and is open to everybody in this class. You certainly may take this lecture course without the lab if you wish, but if you are an Astrophysics major, the lab is required.
Course Text: Universe, Freedman, Geller and Kaufmann, 9th, 10th
or 11th edition. Chapter topics are mostly the same, but for the 9th edition
chapter 21 is broken into chapters 21 and 22.
Class Time: Tuesdays and Thursdays, 11:00 - 12:15pm Class Location: 114 Regener Hall
Office Hours: Monday 10am-noon Room 180, Physics and Astronomy Bldg. (NE corner of Lomas & Yale), or by appointment. For quick questions catch me before or after class.
Homework: There will be regular reading assignments and homework. Reading assignments should be completed BEFORE the class time. Homework assignments will be handed out weekly.
Lectures: I will present lectures in powerpoint, with occasional demonstrations. These lectures and the syllabus can be found at the class web page http://www.phys.unm.edu/~gbtaylor/astr271/ that you are reading now. Some material drawn from my own research, or current events, may not be covered in the book. We will also practice problem-solving using worksheets. And I will ask questions from time to time during lecture. Your participation in responding, and in asking questions of your own, is strongly encouraged.
Grades: There will be two midterms, each worth 25%, and a final exam worth 30%. In addition the homework assignments will count for 20% of the grade. Please take note of the dates of the exams in the syllabus. Make-up exams will only be given if arrangements are made in advance of the exam date. On tests and homework please attempt every problem and show your work as I do give partial credit. Homeworks must be turned in at class on the day when due for full credit. Credit for late homeworks will drop by 15% for every day late within a week, and no credit thereafter. Note: If you take this class "Credit/No Credit", according to university policy, your final grade must be a "C" or better in order to receive credit.
Help with Homework and Tutoring: If you have trouble with the homework feel free to ask me for help in office hours or by appointment. I much prefer meeting in person to trying to answer questions on the homework by e-mail. UNM graduate student Karishma Bansal will also hold office hours from 3-4pm on the day before the homwork is due in room 15 of PandA. Free tutoring for this class is available through CAPS.
