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.

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. -

We find that the coincidences of optically selected 22 2 ..ctive nuclei WIth mildly obscured (NH ;S 1.1 X 10 cm- ) X-ray nuclei are relatively common (8/12), 13 but the detections are too faint « 40 counts per nucleus; 12-10 k,V ;S 1.2 X 10- erg S-1 cm-2 ) to separate starburst and nuclear activity as the origin of the X-ray emission.· Only one merger is found to have confirmed binary X-ray nuclei, though the X-ray emission from its southern nucleus could be due solely to star formation. Thus, the occurrences of binary AGN in these mergers are rare (G-8%), unless most merger-induced active nuclei are very heavily obscured or Compton thiclc Subject headings: galaxies: active - X-rays: galaxies 1. -

OUP UNCORRECTED PROOF – REVISES, Fri May 30 2014, NEWGEN Commons at the Intersection of Peer Production, 6 Citizen Science, and Big Data: Galaxy Zoo Michael J. Madison* I. Introduction Policy analysis of scientific research, particularly in recent decades, has focused on ten- sions between norms of open science and knowledge sharing, on the one hand, and polit- ical and economic pressures to embed scientific research in market-based institutions based on proprietary claims to knowledge, such as modern patent law, on the other hand (Eisenberg 1989; Rai 1999; Reichman & Uhlir 2003). Twenty-first century technologies offer additional challenges and opportunities for science, grounded in the emergence of the Internet as a communications medium and in the explosion in the quantity of data available for study. If contests between norms of open science and the expectation that new knowledge should be propertized frame one (older, but still meaningful) debate about scientific research, then the emergence of so-called Big Data, often referred to more descriptively as data-intensive science (Hey et al. 2009), frames a second, related, and broader new debate. The new question is this: How should new scientific knowledge be governed? Do the historical poles—open science based on the norms of a scientific dis- cipline, versus propertized knowledge grounded in the patent system—still offer the key alternatives? This chapter suggests that they do not. It offers a study of the organization * Michael J.

The main purpose of this study is to investigate aspects regarding the validity of the active galactic nucleus (AGN) unification paradigm (UP). In particular, we focus on the AGN host galaxies, which according to the UP should show no systematic differences depending on the AGN classification. Methods. For the purpose of this study, we used (a) the spectroscopic Sloan Digital Sky Survey (SDSS) Data Release (DR) 14 catalogue, in order to select and classify AGNs using emission line diagnostics, up to a redshift of z = 0:2, and (b) the Galaxy Zoo Project catalogue, which classifies SDSS galaxies in two broad Hubble types: spirals and ellipticals. Results. We find that the fraction of type 1 Seyfert nuclei (Sy1) hosted in elliptical galaxies is significantly larger than the correspond- ing fraction of any other AGN type, while there is a gradient of increasing spiral-hosts from Sy1 to LINER, type 2 Seyferts (Sy2) and composite nuclei. These findings cannot be interpreted within the simple unified model, but possibly by a co-evolution scheme for supermassive black holes (SMBH) and galactic bulges. -
Brian May Plays “God Save the Queen” from the Roof of Buckingham Palace to Commemorate Queen Elizabeth II’S Golden Jubilee on June 3, 2002
Exclusive interview Brian May plays “God Save the Queen” from the roof of Buckingham Palace to commemorate Queen Elizabeth II’s Golden Jubilee on June 3, 2002. © 2002 Arthur Edwards 26 Astronomy • September 2012 As a teenager, Brian Harold May was shy, uncer- tain, insecure. “I used to think, ‘My God, I don’t know what to do, I don’t know what to wear, I don’t know who I am,’ ” he says. For a kid who didn’t know who he was or what he wanted, he had quite a future in store. Deep, abiding interests and worldwide success A life in would come on several levels, from both science and music. Like all teenagers beset by angst, it was just a matter of sorting it all out. Skiffle, stars, and 3-D A postwar baby, Brian May was born July 19, 1947. In his boyhood home on Walsham Road in Feltham on the western side of Lon- science don, England, he was an only child, the offspring of Harold, an electronics engineer and senior draftsman at the Ministry of Avia- tion, and Ruth. (Harold had served as a radio operator during World War II.) The seeds for all of May’s enduring interests came early: At age 6, Brian learned a few chords on the ukulele from his father, who was a music enthusiast. A year later, he awoke one morning to find a “Spanish guitar hanging off the end of my bed.” and At age 7, he commenced piano lessons and began playing guitar with enthusiasm, and his father’s engineering genius came in handy to fix up and repair equipment, as the family had what some called a modest income. -
