Dr. Azriel Goldschmidt Lawrence Berkeley Lab Vol. 55, No. 5 – May 2007 May 16, 2007 – General Meeting 7:00 pm Doors Open . 7:30 pm Announcements . 8:00 pm Speaker DR. AZRIEL GOLDSCHMIDT LAWRENCE BERKELEY LAB LOOKING AT THE UNIVERSE WITH DIFFERENT EYES: THE ICE CUBE HIGH-ENERGY NEUTRINO TELESCOPE Why make dozens of mile and a half deep holes in the Antarctic ice at the South Pole? Why bury in them thousands of glass spheres with light sensors? What do we hope to learn by looking for neutrinos coming from the cosmos? How can we learn about the inner workings of gamma ray bursters, supernovae or active galactic nuclei by looking for neutrinos coming from them? In this talk I will offer answers to these questions and describe how the IceCube telescope detects high‐ energy neutrinos, measures their energy and determines from where they came, thus opening a new window through which to look at our universe. Dr. Azriel Goldschmidt is a staff physicist at the Lawrence Berkeley National Laboratoryʹs Nuclear Science division. Since 1996 he has been doing research in neutrino astrophysics, currently with the IceCube neutrino telescope at the South Pole. Originally from Argentina, Dr. Goldschmidt received his B.Sc. in physics from the Technion Israel Institute of Technology and his Ph.D. in particle physics from the University of California at Berkeley. In recent years his work has focused on the development, implementation and operation of a data acquisition system for the IceCube high energy neutrino telescope. 2007 Club Officers & Contacts Club Telescopes The SFAA owns eight very fine, easy to use, President Kenneth Frank [email protected] loaner telescopes well-suited for deep sky, Vice President Jorge Morales vicepresident@sfaa- planets, and star parties.

  • THE CONSTELLATION MUSCA, the FLY Musca Australis (Latin: Southern Fly) Is a Small Constellation in the Deep Southern Sky
    THE CONSTELLATION MUSCA, THE FLY Musca Australis (Latin: Southern Fly) is a small constellation in the deep southern sky. It was one of twelve constellations created by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman and it first appeared on a 35-cm diameter celestial globe published in 1597 in Amsterdam by Plancius and Jodocus Hondius. The first depiction of this constellation in a celestial atlas was in Johann Bayer's Uranometria of 1603. It was also known as Apis (Latin: bee) for two hundred years. Musca remains below the horizon for most Northern Hemisphere observers. Also known as the Southern or Indian Fly, the French Mouche Australe ou Indienne, the German Südliche Fliege, and the Italian Mosca Australe, it lies partly in the Milky Way, south of Crux and east of the Chamaeleon. De Houtman included it in his southern star catalogue in 1598 under the Dutch name De Vlieghe, ‘The Fly’ This title generally is supposed to have been substituted by La Caille, about 1752, for Bayer's Apis, the Bee; but Halley, in 1679, had called it Musca Apis; and even previous to him, Riccioli catalogued it as Apis seu Musca. Even in our day the idea of a Bee prevails, for Stieler's Planisphere of 1872 has Biene, and an alternative title in France is Abeille. When the Northern Fly was merged with Aries by the International Astronomical Union (IAU) in 1929, Musca Australis was given its modern shortened name Musca. It is the only official constellation depicting an insect. Julius Schiller, who redrew and named all the 88 constellations united Musca with the Bird of Paradise and the Chamaeleon as mother Eve.

  • A Spectroscopic and Dynamical Study of Binary and Other Cepheids
    A spectroscopic and dynamical study of binary and other Cepheids |||||||||||||||||||| A thesis submitted in partial fulfillment of the requirements for the Degree of Doctor of Philosophy in Astronomy in the University of Canterbury by Orlon K. L. Petterson |||||||||{ University of Canterbury 2002 Abstract High resolution observations have been made of a number of southern Cepheids to make an observational and theoretical study of Cepheid variables using radial velocities. The stars studied were part of a long term programme to observe southern variable stars, from which a valuable database of radial velocities gathered over a long period were available. Sixteen ´echelle spectrograph orders in the wavelength region 5400{8600A˚ were used, which included a number of absorption lines covering a range of species and excitation potentials. The line bisector technique was used to measure stellar and telluric lines and to obtain radial velocities. To improve the precision of the radial velocities we used telluric lines to calibrate the observations to a common reference frame. 1 The radial velocities have a precision of 300ms− allowing the detection of velocity 1 ∼ differences of 1 km s− with confidence. The radial velocity data obtained at Mount ∼ John University Observatory (MJUO) was combined with data from various sources to determine the orbits of any Cepheids exhibiting orbital motion. The various orbital parameters were determined for a number of systems and where radial velocities for the companions exist, some estimate of the mass was made. The precision of the radial velocities obtained from MJUO also allowed us to search for line level effects for a number of species among the Cepheid spectra.

SECyT-OA Universidad Nacional de Córdoba, Córdoba. Santiago Paolantonio 2010 La importancia de la Uranometría1 Argentina descansa en las sólidas bases científicas sobre la cual fue realizada. Esta obra, cuidada en los más pequeños detalles, se debe sin dudas a la genialidad del entonces director del Observatorio Nacional Argentino, Dr. Benjamin A. Gould. Pero nada de esto se habría hecho realidad sin la gran habilidad, el esfuerzo y la dedicación brindada por los cuatro primeros ayudantes del Observatorio, John M. Thome, William M. Davis, Miles Rock y Clarence L. Hathaway, así como de Walter G. Davis y Frank Hagar Bigelow que se integraron más tarde a la institución. Entre éstos, J. M. Thome, merece un lugar destacado por la esmerada revisión, control de las posiciones y determinaciones de brillos, tal como el mismo Director lo reconoce en el prólogo de la publicación. Por otro lado, Albert K. Mansfield tuvo un papel clave en la difícil confección de los mapas del Atlas. La Uranometría Argentina sobresale entre los trabajos realizados hasta ese momento, por múltiples razones: Por la profundidad en magnitud, ya que llega por vez primera en este tipo de empresa a la séptima.

  • André Heck GENERAL LIST of PUBLICATIONS 1964-2020
    e-Fonds AH v.2021.3.5 Andr´eHeck GENERAL LIST of PUBLICATIONS 1964-2020 Venngeist Warning The following chronological list is a personal document compiled with the sole purpose of keeping track of what has been published under my authorship/editorship and initiative. Numerous “small” items have been included for the record only. For a list of the most meaningful articles, documents and books in astronomy and related fields, please refer to the scientific biography by Joe Hube1 covering up to Year 2014 and with the contributions sorted out in several categories. The present list represents more than 150,000 published pages of various sizes, but not all of them have been scanned. On one hand, copies of 160 (or so) items were not available anymore in the archive boxes. On the other hand, even if they were differing from one version to the other because of the continual update, it was senseless to scan all (sometimes monthly) editions of the big directories and dictionaries produced by the unit as CDS publications to satisfy the incoming orders. In the available editions, only the first (introductory) pages have been scanned while the ultimate versions (Publ. 1356 & 1357 in Year 2004) have been fully provided in pdf format. Non-personal contributions in books produced as editor have not been listed nor scanned. Compilations such as the present one cannot be absolutely exhaustive, even if pretty close to completion. Finally, it should be emphasized that electronic files are no subsitute for the full collection on paper, but they can support it usefully.
