Porto Alegre 2017 Acknowledgements To my parents, who supported me and made this possible, in a time and place where being in a university was just a distant dream. To my dearest friends Elisabeth, Robert, Augusto, and Natália - who so many times helped me go from "I give up" to "I’ll try once more". To my cats Kira, Fen, and Demi - who lazily join me in bed at the end of the day, and make everything worthwhile. "But, first of all, it will be necessary to explain what is our idea of a cluster of stars, and by what means we have obtained it. For an instance, I shall take the phenomenon which presents itself in many clusters: It is that of a number of lucid spots, of equal lustre, scattered over a circular space, in such a manner as to appear gradually more compressed towards the middle; and which compression, in the clusters to which I allude, is generally carried so far, as, by imperceptible degrees, to end in a luminous center, of a resolvable blaze of light." William Herschel, 1789 Abstract We provide a sample of 170 Galactic Globular Clusters (GCs) and analyse its spatial distribution properties.

  • The 100-Inch Telescope of the Mount Wilson Observatory
    The 100-Inch Telescope of the Mount Wilson Observatory An International Historical Mechanical Engineering Landmark The American Society of Mechanical Engineers June 20, 1981 Mount Wilson Observatory Mount Wilson, California BACKGROUND THE MOUNT WILSON OBSERVATORY was founded in 1904 by the CARNEGIE INSTITUTION OF WASH- INGTON, a private foundation for scientific research supported largely from endowments provided by Andrew Carnegie. Within a few years, the Observatory became the world center of research in the new science of astrophysics, which is the application of principles of physics to astronomical objects beyond the earth. These include the sun, the planets of our solar system, the stars in our galaxy, and the system of galaxies that reaches to the limits of the The completed facility. visible universe. SCIENTIFIC ACHIEVEMENTS The Mount Wilson 100-inch reflector dominated dis- coveries in astronomy from its beginning in 1918 until the dedication of the Palomar 200-inch reflector in 1948. (Both telescopes are primarily the result of the lifework of one man — George Ellery Hale.) Many of the foundations of modern astrophysics were set down by work with this telescope. One of the most important results was the discovery that the intrinsic luminosities (total light output) of the stars could be found by inspection of the record made when starlight is dispersed into a spectrum by a prism or a grating. These so-called spectroscopic absolute lumi- nosities, discovered at Mount Wilson and developed for over forty years, opened the way to an understanding of the evolution of the stars and eventually to their ages. Perhaps the most important scientific discovery of the 20th century is that we live in an expanding Universe.

  • Hubble Sees a Unique Cluster: One of the 'Hidden 15' 22 April 2013
    Hubble sees a unique cluster: One of the 'hidden 15' 22 April 2013 almost always see them in the same region of the sky. Palomar 2 is an exception to this, as it is around five times further away from the center of the Milky Way than other clusters. It also lies in the opposite direction—further out than Earth—and so it is classed as an "outer halo" globular. It is also unusual due to its apparent dimness. The cluster is veiled by a mask of dust, dampening the apparent brightness of the stars within it and making it appear as a very faint burst of stars. The stunning NASA/ESA Hubble Space Telescope image shows Palomar 2 in a way that could not be captured from smaller or ground-based telescopes—some amateur astronomers with large telescopes attempt to observe all of the obscure and well-hidden Palomar 15 as a challenge, to see how many they can pick out from the starry sky. Credit: ESA/NASA, Hubble Provided by NASA (Phys.org) —Palomar 2 is part of a group of 15 globulars known as the Palomar clusters. These clusters, as the name suggests, were discovered in survey plates from the first Palomar Observatory Sky Survey in the 1950s, a project that involved some of the most well-known astronomers of the day, including Edwin Hubble. They were discovered quite late because they are so faint—each is either extremely remote, very heavily hidden behind blankets of dust, or has a very small number of remaining stars. This particular cluster is unique in more than one way.

  • Reflections December 2020
    Surviving the Bobcat Fire By Robert Anderson As recently as December 9, our solar astronomer, Steve Padilla, was taking his evening walk and noticed the smoke of a hotspot flaring up in the canyon just below the Observatory. It was a remnant of the Bobcat Fire, which started nearby on September 6. The local Angeles National Forest firefighters were notified of the flareup, either to monitor it or extinguish it if needed. They have returned many times during the last three months. And we are always glad to see them, especially those individuals who put water to flame here and battled to save the most productive and famous observatory in history. On the sunny Labor Day weekend, when the Bobcat Fire started near Cogswell Reservoir in a canyon east of the Mount Wilson, the Observatory’s maintenance staff went on cautious alert. As the fire spread out of control, it stayed to the east burning north and south of the reservoir for days, threatening communities in the foothills of the San Gabriels. Nevertheless, all non-essential staff and residents were evacuated off the mountain just in case. Under a surreal, smoke-filled September sky, crews David Cendejas, the superintendent of the Observatory, prepare to defend the Observatory. Photo: D. Cendejas and a skeleton crew of CHARA staff, stayed to monitor the situation and to secure the grounds.

Standard 1, Objective 1: Describe both the big bang theory of universe formation and the nebular theory of solar system formation and evidence supporting them. Lesson Objectives • Explain the evidence for an expanding universe. • Describe the formation of the universe according to the Big Bang Theory. Introduction The study of the universe is called cosmology. Cosmologists study the structure and changes in the present universe. The universe contains all of the star systems, galaxies, gas and dust, plus all the matter and energy that exist. The universe also includes all of space and time. Evolution of Human Understanding of the Universe What did the ancient Greeks recognize as the universe? In their model, the universe contained Earth at the center, the Sun, the Moon, five planets, and a sphere to which all the stars were attached. This idea held for many centuries until Galileo's telescope allowed people to recognize that Earth is not the center of the universe. They also found out that there are many more stars than were visible to the naked eye. All of those stars were in the Milky Way Galaxy. 13 Timeline of cosmological theories 4th century BCE — Aristotle proposes a Geocentric (Earth-centered) universe in which the Earth is stationary and the cosmos (or universe) revolves around the Earth.

SMOOTH NO METALS V. LUMPY, METAL RICH Galaxies – AS 3011 2 1 The Mass-Age plot 1. Completing the local census 2. Comparative studies Galaxies – AS 3011 3 Dwarf galaxies • Dwarf galaxies are a crucial part of the galaxy evolution puzzle but we know very little about them. • Main theory (see later) proposes that galaxies built-up from smaller units through repeated merging. • Numerical simulations typically predict several thousand dark matter haloes in the local group. • ~ 55 Local Group galaxies known. • ~ 1 new Local Group dwarf galaxy discovered every 18 months. • Very wide range of properties = a combination of late- starters, relics, debris and stunted systems. • Space-density extremely poorly constrained, I.e., important to appreciate that our current backyard census is woefully incomplete. Galaxies – AS 3011 4 2 2 New Local Group galaxies discovered recently… • Bootes • Mv=-5.7 mag • µo=28.1 mag/sq arcsec • Belokurov et al (2006) • Canes Venatici • MV=-7.9 mag • µo=27.8 mag/sq arcsec • Zuker et al (2006) Galaxies – AS 3011 5 The Luminosity-Surface Brightness Plane Galaxies – AS 3011 6 3 Comparative studies • Many comparisons are possible, e.g., – Profile shapes – Gas, dust, plasma and stellar content – Fundamental plane and Faber-Jackson relation – Tully-Fischer relation – Star-formation rates – Line indices, metallicity and colours – Morphologies and luminosity-size relations – Overall and component luminosity functions • Main issues are sample selection bias and demonstrating that a comparison of the high and low z samples is valid, comprehensive and complete.
