Laboratory Astrophysics Is the Rosetta Stone That Symposium Enables Astronomers to Understand and Interpret the Distant Cosmos
IAU Symposium IAU IAU Symposium Proceedings of the International Astronomical Union Laboratory astrophysics is the Rosetta Stone that Symposium enables astronomers to understand and interpret the distant cosmos. It provides the tools to interpret and 350 guide astronomical observations and delivers the numbers needed to quantitatively model the processes 350 taking place in space, providing a bridge between 350 Laboratory 14-19 April 2019 observers and modelers. IAU Symposium 350 was 14-19 April 2019 Cambridge, United Kingdom organized by the International Astronomical Union's Cambridge, United Kingdom Laboratory Astrophysics Commission (B5), and was the Interpretation Observations to From Astrophysics: rst topical symposium on laboratory astrophysics Laboratory sponsored by the IAU. Active researchers in observational astronomy, space missions, experimental From Observations Astrophysics: and theoretical laboratory astrophysics, and Laboratory Astrophysics: From Observations astrochemistry discuss the topics and challenges facing astronomy today. Five major topics are covered, to Interpretation to Interpretation spanning from star- and planet-formation through stellar populations to extragalactic chemistry and dark matter. Within each topic, the main themes of laboratory studies, astronomical observations, and theoretical modeling are explored, demonstrating the breadth and the plurality of disciplines engaged in the growing eld of laboratory astrophysics. Edited by Proceedings of the International Astronomical Union Salama and Linnartz Farid Salama Editor in Chief: Professor Maria Teresa Lago This series contains the proceedings of major scienti c Harold Linnartz meetings held by the International Astronomical Union. Each volume contains a series of articles on a topic of current interest in astronomy, giving a timely overview of research in the eld. With contributions by leading scientists, these books are at a level suitable for research astronomers and graduate students. -
RADIAL VELOCITIES in the ZODIACAL DUST CLOUD
A SURVEY OF RADIAL VELOCITIES in the ZODIACAL DUST CLOUD Brian Harold May Astrophysics Group Department of Physics Imperial College London Thesis submitted for the Degree of Doctor of Philosophy to Imperial College of Science, Technology and Medicine London · 2007 · 2 Abstract This thesis documents the building of a pressure-scanned Fabry-Perot Spectrometer, equipped with a photomultiplier and pulse-counting electronics, and its deployment at the Observatorio del Teide at Izaña in Tenerife, at an altitude of 7,700 feet (2567 m), for the purpose of recording high-resolution spectra of the Zodiacal Light. The aim was to achieve the first systematic mapping of the MgI absorption line in the Night Sky, as a function of position in heliocentric coordinates, covering especially the plane of the ecliptic, for a wide variety of elongations from the Sun. More than 250 scans of both morning and evening Zodiacal Light were obtained, in two observing periods – September-October 1971, and April 1972. The scans, as expected, showed profiles modified by components variously Doppler-shifted with respect to the unshifted shape seen in daylight. Unexpectedly, MgI emission was also discovered. These observations covered for the first time a span of elongations from 25º East, through 180º (the Gegenschein), to 27º West, and recorded average shifts of up to six tenths of an angstrom, corresponding to a maximum radial velocity relative to the Earth of about 40 km/s. The set of spectra obtained is in this thesis compared with predictions made from a number of different models of a dust cloud, assuming various distributions of dust density as a function of position and particle size, and differing assumptions about their speed and direction. -

Selected Highlights of Women's History
Selected Highlights of Women’s History United States & Connecticut 1773 to 2015 The Permanent Commission on the Status of Women omen have made many contributions, large and Wsmall, to the history of our state and our nation. Although their accomplishments are too often left un- recorded, women deserve to take their rightful place in the annals of achievement in politics, science and inven- Our tion, medicine, the armed forces, the arts, athletics, and h philanthropy. 40t While this is by no means a complete history, this book attempts to remedy the obscurity to which too many Year women have been relegated. It presents highlights of Connecticut women’s achievements since 1773, and in- cludes entries from notable moments in women’s history nationally. With this edition, as the PCSW celebrates the 40th anniversary of its founding in 1973, we invite you to explore the many ways women have shaped, and continue to shape, our state. Edited and designed by Christine Palm, Communications Director This project was originally created under the direction of Barbara Potopowitz with assistance from Christa Allard. It was updated on the following dates by PCSW’s interns: January, 2003 by Melissa Griswold, Salem College February, 2004 by Nicole Graf, University of Connecticut February, 2005 by Sarah Hoyle, Trinity College November, 2005 by Elizabeth Silverio, St. Joseph’s College July, 2006 by Allison Bloom, Vassar College August, 2007 by Michelle Hodge, Smith College January, 2013 by Andrea Sanders, University of Connecticut Information contained in this book was culled from many sources, including (but not limited to): The Connecticut Women’s Hall of Fame, the U.S. -

A combined approach of image deconvolution and modelling has made it possible to investigate the starlight distribution in M87 down to a limiting radius of about 0'.'04 from the nucleus (or about 3 pc from the nucleus if the Virgo cluster is at 16 Mpc). The results show that the central struc ture of M87 can be described by three compo nents: a power-law starlight profile with an r·114 slope which continues unabated into the center, an unresolved central point source, and optical coun terparts of the jet knots identified by VLBI obser vations. In both the V- and /-band Planetary Camera images, the stellar cusp is consistent with the black-hole model proposed for M87 by Young et al. in 1978; in this model, there is a central mas sive object of about 3 x 109 Me. -
A Thin Diffuse Component of the Galactic Ridge X-Ray Emission and Heating of the Interstellar Medium Contributed by the Radiation of Galactic X-Ray Binaries
A&A 564, A107 (2014) Astronomy DOI: 10.1051/0004-6361/201323332 & c ESO 2014 Astrophysics A thin diffuse component of the Galactic ridge X-ray emission and heating of the interstellar medium contributed by the radiation of Galactic X-ray binaries Margherita Molaro1, Rishi Khatri1, and Rashid A. Sunyaev1,2 1 Max Planck Institut für Astrophysik, Karl-Schwarzschild-Str. 1, 85741 Garching, Germany e-mail: [email protected] 2 Space Research Institute, Russian Academy of Sciences, Profsoyuznaya 84/32, 117997 Moscow, Russia Received 23 December 2013 / Accepted 14 January 2014 ABSTRACT We predict athindiffuse component of the Galactic ridge X-ray emission (GRXE) arising from the scattering of the radiation of bright X-ray binaries (XBs) by the interstellar medium. This scattered component has the same scale height as that of the gaseous disk (∼80 pc) and is therefore thinner than the GRXE of stellar origin (scale height ∼130 pc). The morphology of the scattered component is furthermore expected to trace the clumpy molecular and HI clouds. We calculate this contribution to the GRXE from known Galactic XBs assuming that they are all persistent. The known XBs sample is incomplete, however, because it is flux limited and spans the lifetime of X-ray astronomy (∼50 years), which is very short compared with the characteristic time of 1000−10 000 years that would have contributed to the diffuse emission observed today due to time delays. We therefore also use a simulated sample of sources, to estimate the diffuse emission we should expect in an optimistic case assuming that the X-ray luminosity of our Galaxy is on average similar to that of other galaxies. -

DESCRIPTORS Annotated Bibliographies; *Biographies; Elementary Secondary Education; Engineering Education; *Females; Role Models; Science Careers; Science Education; *Scientists ABSTRACT The participation of women in the physical sciences and engineering woefully lags behind that of men. One significant vehicle by which students learn to identify with various adult roles is through the literature they read. This annotated bibliography lists and describes biographies on women scientists primarily focusing on publications after 1980. The sections include: (1) anthropology, (2) astronomy,(3) aviation/aerospace engineering, (4) biology, (5) chemistry/physics, (6) computer science,(7) ecology, (8) ethology, (9) geology, and (10) medicine.
