Detailed Description: This course will serve as an introduction to the tools and techniques used in optical astronomy. This course will provide you with "hands-on" experience using astronomical tools. There will be several lab sessions intended to familiarize you with the operation of optical and radio telescope hardware, software and their accessories. The TA and/or the instructor will evaluate your proficiency in the use of the equipment by having you perform demonstrations of the usage of the various pieces of equipment. Measurements of basic properties of astronomical objects will be performed. Quantitative analysis of these measurements will enable us to determine quantities such as the mass of Jupiter as well as the ages of stars. The course will cover the following topics: · Basic Observational Techniques • Finding astronomical objects. • Imaging astronomical objects with a CCD camera. • Filters and Photometry. • Design and use of spectrographs. • Atmospheric effects and limitations. • Basic Concepts of Radio Astronomy (Time and equipment permitting) · Analysis of Astrophysical Measurements • Image Processing • Acquisition and analysis of spectra from astrophysical sources • Analysis of photometric observations • Measurements of astrophysical quantities using simulated observations Observing projects will be an integral component of the course. The facilities available include one 14" Optical telescope, one 12" , one 11” and four 10" optical telescopes. Each of the optical telescopes will be equipped with a CCD camera. An SBIG self-guiding spectrograph capable of identifying objects such as quasars is also available. Computer equipment is available to store and analyze the images obtained from each telescope. The observing projects may include, Cepheid variable stars, gaseous nebulae, galactic rotation, color-magnitude diagrams for star clusters. Prerequisites: Algebra, Familiarity with computers, PHYS 1060 or PHYS 1070, and PHYS 2220. Reading Material: All of the required reading material for this course will be provided in PDF files on our class web site. Lectures: A review of basic astronomy and astrophysics as well as some optics will be presented. A catalog of astrophysical objects will be presented and described. Since a large component of this course in observational astronomy will be devoted to analyzing starlight, material relevant to the relevant physics will be presented. An in-depth discussion of the theory of stars and stellar evolution will also be presented. Particular emphasis will be placed on the basic physics involved in interpreting observational data to develop an understanding of astrophysical objects. It is highly recommended for those students who have not attended a basic astronomy course to acquire and study a textbook in basic astronomy. Observing Projects: The following projects will involve actual observations performed by you using the department's observatory equipment. Some of these exercises will also require written reports (4060) to be submitted for grades. • Basic Setup and Usage of a Computer Controlled Telescope. • Basic Setup and usage of CCD Cameras. • Flat-Field and other Techniques to improve CCD Imaging. • Color Imaging. • Solar Observations (Carefully). • Lunar Observations. • Planetary Observations. • Observations of Planetary Satellites. • Deep Sky Imaging: Galaxies • Deep Sky Imaging: Nebulae • Deep Sky Imaging: Globular Clusters • Basic Usage of Spectrographs. • Measurement of Stellar Color Index with UVBRI filter sets. • *Observing the Sun at Radio Wavelengths. • *Observing the Milky Way at Radio Wavelengths. • *Use of 32” telescope located at Frisco Peak. *Denotes possible additional observing activities depending on availability of additional resources. Computer Laboratory Exercises: There will be several laboratory sessions intended to familiarize you with the use of the hardware associated with the course. These sessions will be in the form of demonstrations and "hands-on" workshops to enable you to learn how to use the equipment. Examples of such sessions would be a "workshop" on how to set up and align a telescope or how to acquire an image using a CCD camera. Additionally this course uses several different software packages for navigating the night sky, controlling telescopes and the acquisition and processing of CCD images. A list of software used in this course has been provided above. Several laboratory sessions will be devoted to learning how to use some of these software packages. Additionally we will be using software to perform laboratory exercises where data will be analyzed and measurements performed. Typically in these exercises we will use software to simulate astronomical data. This data will then be analyzed to determine some properties of astrophysical objects. You will be expected to write a brief report describing the "observations" that you made using the simulation software as well as describe the analysis that you performed using this simulated data. The following is a list of laboratory exercises that we may/will be performing during the semester • Familiarization with the Sky. (Starry Night Pro) • The Revolution of the Moons of Jupiter. (CLEA) • Radar Measurements of the Rotation Rate of Mercury. (CLEA) • The Flow of Energy out of the Sun. (CLEA) • Photoelectric Photometry of the Pleiades. (CLEA) • Classification of Stellar Spectra. (CLEA) • The Hubble Redshift Distance Relation. (CLEA) • The Large Scale Structure of the Universe. (CLEA) • Radio Astronomy of Pulsars(CLEA) • Others… Schedule: On cloudy nights, we will work on computer based exercises or image processing. There will be additional observing sessions scheduled later in the semester. It should also be noted that class start times will start following sunset later in the semester. Class times may extend beyond 9PM for observing sessions. Solar observing sessions that will occur later in the semester will start earlier in the day at least one hour prior to sunset. Tentative Course Requirements and Grades: There will be in-class laboratory exercises using various software tools to simulate astronomical data. You will perform exercises in the analysis of these data sets. Brief reports will be required and graded for these laboratory exercises. In addition to the laboratory sessions and exercises there will also be reading assignments/homework, quizzes and a final exam. Homework assignments WILL NOT be collected or graded. The main purpose of the homework assignments will be to help you prepare for quizzes as well as the final exam. A comprehensive final exam will also be given. The TENTATIVE grading scheme is as follows: Activity Tentative Weight Class Exercises 25% Observing Exercises 20% Written Reports 25% Midterm Exam 10% Final Exam 20% Written Reports (4060 students only): A written report is to be prepared for some of the laboratory exercises or projects performed by students enrolled in PHYS 4060. A standard outline for an experimental report is the following: 1.Introduction - Description of Physics Topic to be studied 2.Description of experimental procedure: Apparatus - Drawings are often helpful Procedure 3.Presentation of raw data 4.Analysis of data Extraction of physics results Estimation of statistical uncertainties Estimation of systematic uncertainties 5.Conclusions Presentation of results Comparison with theory Discussion of possible improvements,... It is imperative that the report is LEGIBLE. Typewritten reports are more likely to meet this requirement than handwritten reports. However, it is not necessary to spend inordinate amounts of time assuring that the report is aesthetically perfect. Hand drawn figures pasted into the report are acceptable.

During the 14 lab sessions, we will encounter objects located in our own solar system, stars filling the Milky Way, and objects located much further away in the far reaches of space. Astronomy is an observational science, as opposed to most of the rest of physics, which is experimental in nature. Astronomers cannot create a star in the lab and study it, walk around it, change it, or explode it. Astronomers can only observe the sky as it is, and from their observations deduce models of the universe and its contents. They cannot ever repeat the same experiment twice with exactly the same parameters and conditions. Remember this as the universe is laid out before you in Astronomy 113 – the story always begins with only points of light in the sky. From this perspective, our understanding of the universe is truly one of the greatest intellectual challenges and achievements of mankind. The exploration of the universe is also a lot of fun, an experience that is largely missed sitting in a lecture hall or doing homework.

  • Astronomical Observations: a Guide for Allied Researchers
    Astronomical observations: a guide for allied researchers P. Barmby Department of Physics & Astronomy University of Western Ontario London, Canada N6A 3K7 March 13, 2019 Abstract Observational astrophysics uses sophisticated technology to collect and measure electro- magnetic and other radiation from beyond the Earth. Modern observatories produce large, complex datasets and extracting the maximum possible information from them requires the expertise of specialists in many fields beyond physics and astronomy, from civil engineers to statisticians and software engineers. This article introduces the essentials of professional astronomical observations to colleagues in allied fields, to provide context and relevant back- ground for both facility construction and data analysis. It covers the path of electromagnetic radiation through telescopes, optics, detectors, and instruments, its transformation through processing into measurements and information, and the use of that information to improve our understanding of the physics of the cosmos and its history. 1 What do astronomers do? Everyone knows that astronomers study the sky. But what sorts of measurements do they make, and how do these translate into data that can be analyzed to understand the universe? This article introduces astronomical observations to colleagues in related fields (e.g., engineering, statistics, computer science) who are assumed to be familiar with quantitative measurements and computing but not necessarily with astronomy itself.1 Specialized terms which may be unfamiliar to the reader are italicized on first use. The references in this article include a mix of technical papers and less- technical descriptive works. Shorter introductions to astronomical observations, data and statistics are given by [29, 33]. Comprehensive technical introductions to astronomical observations are found in several recent textbooks [12, 45, 50].
