Exam BASICS OF ASTRONOMY? • Observational Coordinate systems techniques • Feasibility • Source Emission spectrum mechanisms • Source properties • What kind of ELEC-E4530 Radio Astronomy Astronomy sources? ELEC-E4220 Space Instrumentation (galactic & extragalactic) • What kind of science? Why do we study astronomy on this course Needed on other space courses, and by anyone who wishes to continue in astronomical research. The astronomy part on this course consists of coordinate systems, emission mechanisms, and the basics of celestial objects, such as galactic and extragalactic sources. REMINDER: LUMINOSITY The luminosity emitted by a source (= the total radiated energy) L = 4r2 σT4 can be divided into two parts: L = 4r2F F = σT4 (Stefan-Boltzmann law) Luminosity is proportional to the size and the fourth power of the temperature High luminosity → the source is hot or large in size, or both Effective temperature = the temperature of a black body that would emit the same total amount of electromagnetic radiation BRIGHTNESS OF STARS? MAGNITUDE SYSTEMS Describe the optical brightness of celestial objects Logarithmic 2 Apparent magnitude: m = –2.5 lg F/F0 [F]=W/m m1 – m2 = –2.5 lg F1/F2 Bolometric magnitude at all wavelengths: mbol=mv- BC Visual magnitude mv corresponds to the sensitivity of the eye Absolute magnitude M (= the apparent m at a distance of 10pc): m – M = 5 lg (r/10pc) Absolute bolometric magnitude: Mbol – Mbol, = –2.5 lg L/L BC = Bolometric correction, zero for sun-like emission. -

Galaxy classification (courtesy Heather Morrison) Sandage's "The Hubble Atlas of Galaxies" (on reserve in the library, or available online, although the online version is hard to read) gives a detailed description of the traditional Hubble classification. Read pages 7-26 of the Hubble Atlas to familiarize yourself with the classification scheme. Then go to the Sloan Digital Sky Survey and look at galaxy images using the Navigator function to classify the galaxies in the table below. In each case, write a short paragraph explaining why you chose this classification. You should include comparison galaxies in the Hubble atlas which you used to classify each galaxy. Note any difficulties you had applying Sandage's rules. It may be helpful for you to type the NGC numbers of some of the Hubble Atlas galaxies into Navigator so you can see, for example, what HII regions look like in color images, etc. # RA Dec 1 221.546 –0.223 2 145.514 +0.336 3 39.849 +1.094 4 36.907 –1.155 5 152.110 +12.300 6 161.957 +12.582 7 Another galaxy of your choice near one of these galaxies.

The Ringed Spiral Galaxy NGC 4622. I. Photometry, Kinematics, and the Case for Two Strong Leading Outer Spiral Arms1 Ronald J. Buta2 and Gene G. Byrd Department of Physics & Astronomy Department, University of Alabama, Tuscaloosa, AL 35487, USA and Tarsh Freeman Bevill State Community College, Fayette, AL, USA ABSTRACT The intriguing nearly face-on southern ringed spiral galaxy NGC 4622, the first galaxy defini- tively shown to have leading spiral structure, is revisited in this paper with new images from the Hubble Space Telescope’s WFPC2, together with ground-based optical and near-IR imaging, and a Fabry-Perot Hα velocity field. The data provide new information on the disk/bulge/halo mix, rotation curve, star formation in the galaxy, and the sense of winding of its prominent spiral arms. Previously, we suggested that the weaker, inner single arm most likely has the leading sense, based on a numerical simulation. Now, taking advantage of HST resolution and using de Vaucouleurs’ standard extinction and reddening technique to determine the near side of the galaxy’s slightly tilted disk, we come to the more surprising conclusion that the two strong outer arms have the leading sense. We suggest that this highly unusual configuration may be the result of a past minor merger or mild tidal encounter. Possible evidence for a minor merger is found in a short, central dust lane, although this is purely circumstantial and an unrelated interaction with a different companion could also be relevant. The leading arms may be allowed to persist because NGC 4622 is dark halo-dominated (i.e., not “maximum disk” in the inner regions) and displays a significantly rising rotation curve. -

Canvas and Cosmos: Visual Art Techniques Applied to Astronomy Data

JAYANNE ENGLISH∗ Department of Physics and Astronomy, University of Manitoba, Winnipeg, Manitoba, R3T 2N2, Canada. Jayanne [email protected] Received Day Month Year Revised Day Month Year Bold colour images from telescopes act as extraordinary ambassadors for research astronomers because they pique the public's curiosity. But are they snapshots docu- menting physical reality? Or are we looking at artistic spacescapes created by digitally manipulating astronomy images? This paper provides a tour of how original black and white data, from all regimes of the electromagnetic spectrum, are converted into the colour images gracing popular magazines, numerous websites, and even clothing. The history and method of the technical construction of these images is outlined. However, the paper focuses on introducing the scientific reader to visual literacy (e.g. human per- ception) and techniques from art (e.g. composition, colour theory) since these techniques can produce not only striking but politically powerful public outreach images. When cre- ated by research astronomers, the cultures of science and visual art can be balanced and the image can illuminate scientific results sufficiently strongly that the images are also used in research publications. Included are reflections on how they could feedback into astronomy research endeavours and future forms of visualization as well as on the rele- vance of outreach images to visual art.

The Chemically Distinct Nucleus and Structure of the S0 Galaxy NGC 80 O

Nizhni˘ı Arkhyz, Karacha ˘ı -Cherkessia, Russia Received April 3, 2002; in final form, May 23, 2002 Abstract—The giant lenticular galaxy NGC 80, which is the brightest member of a rich group, possesses a central evolutionarily-distinct region: the stars in the nucleus and in a circumnuclear ring of radius 5t–7 have a mean age of only 7 Gyr, whereas the stellar population of the bulge is older than 10 Gyr. The nucleus of NGC 80 is also chemically distinct: it is a factor of 2–2.5 richer in metals than its immediate neighborhood and is characterized by a high magnesium-to-iron abundance ratio [Mg/Fe] ≈ +0.3.The global stellar disk of NGC 80 has a two-tiered structure: its outer part has an exponential scale length of 11 kpc and normal surface density, while the inner disk, which is also exponential and axisymmetric, is more compact and brighter. Although the two-tiered structure and the chemically distinct nucleus obviously have a common origin and owe their existence to some catastrophic restructuring of the protogalactic gaseous disk, the origin of this remains unclear, since the galaxy lacks any manifestations of perturbed morphology or triaxiality. -

NASA History Program Office, publisher. Title: Not Yet Imagined : A study of Hubble Space Telescope Operations / Christopher Gainor. Description: Washington, DC: National Aeronautics and Space Administration, Office of Communications, NASA History Division, [2020] | Series: NASA history series ; sp-2020-4237 | Includes bibliographical references and index. | Summary: “Dr. Christopher Gainor’s Not Yet Imagined documents the history of NASA’s Hubble Space Telescope (HST) from launch in 1990 through 2020. This is considered a follow-on book to Robert W. Smith’s The Space Telescope: A Study of NASA, Science, Technology, and Politics, which recorded the development history of HST. Dr. Gainor’s book will be suitable for a general audience, while also being scholarly. Highly visible interactions among the general public, astronomers, engineers, govern- ment officials, and members of Congress about HST’s servicing missions by Space Shuttle crews is a central theme of this history book. Beyond the glare of public attention, the evolution of HST becoming a model of supranational cooperation amongst scientists is a second central theme. Third, the decision-making behind the changes in Hubble’s instrument packages on servicing missions is chronicled, along with HST’s contributions to our knowledge about our solar system, our galaxy, and our universe. -
