  • Lurking in the Shadows: Wide-Separation Gas Giants As Tracers of Planet Formation
    Lurking in the Shadows: Wide-Separation Gas Giants as Tracers of Planet Formation Thesis by Marta Levesque Bryan In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California 2018 Defended May 1, 2018 ii © 2018 Marta Levesque Bryan ORCID: [0000-0002-6076-5967] All rights reserved iii ACKNOWLEDGEMENTS First and foremost I would like to thank Heather Knutson, who I had the great privilege of working with as my thesis advisor. Her encouragement, guidance, and perspective helped me navigate many a challenging problem, and my conversations with her were a consistent source of positivity and learning throughout my time at Caltech. I leave graduate school a better scientist and person for having her as a role model. Heather fostered a wonderfully positive and supportive environment for her students, giving us the space to explore and grow - I could not have asked for a better advisor or research experience. I would also like to thank Konstantin Batygin for enthusiastic and illuminating discussions that always left me more excited to explore the result at hand. Thank you as well to Dimitri Mawet for providing both expertise and contagious optimism for some of my latest direct imaging endeavors. Thank you to the rest of my thesis committee, namely Geoff Blake, Evan Kirby, and Chuck Steidel for their support, helpful conversations, and insightful questions. I am grateful to have had the opportunity to collaborate with Brendan Bowler. His talk at Caltech my second year of graduate school introduced me to an unexpected population of massive wide-separation planetary-mass companions, and lead to a long-running collaboration from which several of my thesis projects were born.

Tijuana−Ensenada, Ensenada 22860, México Received XXX / Accepted YYY ABSTRACT Context. Studies of nearby galaxies reveal that around 50% of the total Hα luminosity in late-type spirals originates from diffuse ionised gas (DIG), which is a warm, diffuse component of the interstellar medium that can be associated with various mechanisms, the most important ones being ’leaking’ HII regions, evolved field stars, and shocks.

Historical Introduction and General Characteristics of the CXB. 3 Historical Introduction * The “birth” of the field of X-ray astronomy is usually associated with the flight of a particular rocket experiment in 1962 that yielded the detection of the first non-solar cosmic X-ray source: Scorpius X-1. (Giacconi et al. 1962) * That same rocket experiment also yielded the discovery of an apparent diffuse component of X-radiation, the Cosmic X-ray Background (CXB). (N.B. This was well in advance of the discovery of the Cosmic Microwave Background by Pensias and Wilson!) * In the ensuing 40 some odd years, our understanding of the X-ray Universe has progressed considerably. X-rays have now been detected from virtually all classes of astronomical systems, ranging from normal stars to the most distant galaxies. * Nevertheless, the precise origin of the CXB remains puzzling. This has been one of the great mysteries of high energy astrophysics! 4 Historical Introduction 5 Historical Introduction * “The diffuse character of the observed background radiation does not permit a positive determination of its nature and origin. However, the apparent absorption coefficient in mica and the altitude dependence is consistent with radiation of about the same wavelength responsible for the peak.

  • Doing Business with Wallops Flight Facility
    National Aeronautics and Space Administration Doing Business with NASA’s Wallops Flight Facility NASA’s Wallops Flight Facility (WFF) in Virginia provides agile, low-cost flight and launch range ser- vices to meet government and commercial sector needs for accessing flight regimes worldwide from the Earth’s surface to the moon and beyond. As a multi-user facility with operational launch range, spaceport, and airfield assets, Wallops is well-positioned to meet ongoing and emerging needs in the science, aerospace, defense, and commercial industries. WALLOPS RANGE The Wallops Range supports many of the mission activities around WFF and abroad. Project managers utlize the support of range services to provide a broad array of technical and instrumentation services, such as radar, optical tracking, telemetry, meteorological, command and control, surveillance and recovery, financial analysis and engineering services to support scientific research and technology development. WALLOPS MOBILE ASSETS Wallops has semi-permanent downrange instrumentation as well as mobile instrumentation to include radar, telemetry, command/control, and data systems that can be transported to offsite and remote locations. Campaigns have been conducted from the semi-permanent locations in Bermuda and North Carolina, as well as from the Arctic and Antarctic regions, South America, Africa, Europe, Australia and even at sea, with our mobile systems. WFF personnel have extensive experience in planning and conducting downrange support and mobile campaigns, developing equipment and systems to support these operations. Downrange and mobile systems include the following: C-band radar, meteorology, optical tracking, orbital tracking, flight termination, telemetry, timing, surveillance, and recovery. Keith Thompson, Wallops Advanced Projects Office | 757-824-1680 www.nasa.gov/wallops MID-ATLANTIC REGIONAL SPACEPORT Virginia’s Mid-Atlantic Regional Spaceport at Wallops supports two launch facilities, one medium-lift liquid-fueled pad and a medium-lift solid propellant pad.

Called “Cool Stars, Stellar Systems, and the Sun,” the meeting empha- sized the solar stellar connection and focused discussion on “several topics … in which the similarity is manifest: the structures of chromospheres and coronae, stellar activity, and the phenomena of mass loss,” according to the preface of the resulting, “Special Report of the Smithsonian Astrophysical Observatory.” We could easily have chosen the same topics for this meeting. Over the summer of 1980, the group met again in Bonas, France and then back in Cambridge in 1981. Nearly 40 years on, I am comfortable saying these workshops have evolved to be the premier conference series for cool star research. Cool Stars has been held largely biennially, alternating between North America and Europe. Over that time, the field of stellar astro- physics has been upended several times, first by results from Hubble, then ROSAT, then Keck and other large aperture ground-based adaptive optics telescopes.

Wilson-Hodgeas, Shu Zhangat Abstract High mass X-ray binaries are among the brightest X-ray sources in the Milky Way, as well as in nearby Galaxies. Thanks to their highly variable emissions and complex phenomenology, they have attracted the interest of the high energy astrophysical community since the dawn of X-ray Astronomy. In more recent years, they have challenged our comprehension of physical processes in many more energy bands, ranging from the infrared to very high energies. In this review, we provide a broad but concise summary of the physical processes dominating the emission from high mass X-ray binaries across virtually the whole electromagnetic spectrum.

    SPACE PATTERNS AND PAINTINGS (published in the "Engineer" magazine No. 8-9, 2012) Sagredo. - If the end of the pen, which was on the ship during my entire voyage from Venice to Alexandretta, were able to leave a visible trace of its entire path, then what kind of trace, what mark, what line would it leave? Simplicio. - I would leave a line stretching from Venice to the final place, not completely straight, or rather, extended in the form of an arc of a circle, but more or less wavy, depending on how much the ship swayed along the way ... Sagredo. - If, therefore, the artist, upon leaving the harbor, began to draw with this pen on a sheet of paper and continued drawing until Alexandretta, he could get from his movement a whole picture of figures ... at least a trace left ... by the end of the pen would be nothing more than a very long and simple line. G. Galileo "Dialogue on the two main systems of the world" Space has been giving astronomers surprise after surprise lately. A number of mysterious space objects were discovered that were not predicted by astrophysics and contradicted it. The more advanced observation methods become, the more such surprises. At one time, I. Shklovsky argued that the discovery of such "cosmic wonders" would confirm the reality of extraterrestrial intelligence, its enormous technical capabilities. But in reality, the "cosmic miracles" showed the backwardness of terrestrial science, which the opium of relativism smiled so much that now it cannot clearly explain ordinary cosmic phenomena caused by natural causes.
