Galaxies and Their Masks


Book Description

The year: 1660. The date: November 28. Present: The Lord Brouncker, Mr Boyle, Mr Bruce, Sir Robert Moray, Sir Paule Neile, Dr Wilkins, Dr Goddard, Dr Petty, Mr Ball, Mr Hooke, Mr Wren, and Mr Hill. Occasion: A lecture by Mr Wren at Gresham College, United Kingdom. AfterChristopherWrenhaddeliveredhislectureatGreshamCollegeonthathistoric occasion in November 1660, they did according to the usual manner, withdraw for mutual converse. It was in 1660 that the Royal Society was founded, with 12 persons present. This year, 2010, is thus a special year for scientists worldwide: it celebrates the 350th anniversary of the founding of the Royal Society, whose current President is Martin Rees. One of the enormous challenges facing scientists in the 1600s was the great need fortheclassi cationofobjectstheywerestudying, particularlyinthe eldofbotany. The seeds for classi cation lie in the works of the British naturalist John Ray (1628 1705), who commencing in 1660 with hisCatalogusplantarumcirca Cantabrigiamnascentium (Catalogue of Cambridge Plants) published in the year in which the Royal Society was founded and ending with the posthumous publi- tion ofSynopsisMethodicaAviumetPiscium in 1713, pioneered systematic studies on plants, birds, mammals, sh, and insects."




Shrouds of the Night


Book Description

The Milky Way has captivated the mind of multitudes ever since the beginning of time. Particularly striking are its apparent dusty gaping voids. With the advent of near-infrared technology, astronomers have discovered an awesome new view of its structure, and of the structure of other galaxies around us. Galaxies are encased within Shrouds of the Night: shrouds or veils of cosmic dust, which have given us a totally incomplete picture of what our majestic Universe actually looks like. In this book, we feature some of the remarkable early photographic work of masters such as Isaac Roberts and Edward Barnard, before presenting to the reader the unmasked (dust penetrated) view of our cosmos, using some of the world’s largest ground and space-based telescopes.




Penetrating Bars through Masks of Cosmic Dust


Book Description

THE EDITORS: DAVID L. BLOCK AND KENNETH C. FREEMAN (SOC CO-CHAIRS), IVANIO PUERARI, ROBERT GROESS AND LIZ K. BLOCK 1. Harvard College Observatory, 1958 The past century has truly brought about an explosive period of growth and discovery for the physical sciences as a whole, and for astronomy in particular. Galaxy morphology has reached a renaissance . . The year: 1958. The date: October 1. The venue: Harvard College Observatory. The lecturer: Walter Baade. With amazing foresight, Baade penned these words: "Young stars, supergiants and so on, make a terrific splash - lots of light. The total mass of these can be very small compared to the total mass of the system". Dr Layzer then asked the key question: " . . . the discussion raises the point of what this classification would look like if you were to ignore completely all the Population I, and just focus attention on the Population II . . . " We stand on the shoulders of giants. The great observer E. E. Barnard, in his pioneering efforts to photograph the Milky Way, devoted the major part of his life to identifying and numbering dusty "holes" and dust lanes in our Milky Way. No one could have dreamt that the pervasiveness of these cosmic dust masks (not only in our Galaxy but also in galaxies at high redshift) is so great, that their "penetration" is truly one of the pioneering challenges from both space-borne telescopes and from the ground.

Toward a New Millennium in Galaxy Morphology


Book Description

South Africa - a land of paradigm shifts. A land where we are willing to leave behind the old, to bravely accept the new. What do we need to exit the dark ages in the morphology of galaxies? How prevalent is the cherishing of old concepts? Traditional morphology has been `mask-oriented', focusing on masks of dust and gas which may constitute only 5 percent of the dynamical mass of a galaxy. Some of the world's foremost astronomers flew to South Africa to address morphologically related issues at an International Conference, the proceedings of which are contained in this volume. Examine predicted extinction curves for primordial dust at high redshift. Stars evolve; why not dust? Read about the breakdown of the Hubble sequence at a redshift of one. Explore the morphology of rings; the mysteries of metal-rich globular clusters; vigorous star-formation in the Large Magellanic Cloud; the world of secular evolution, where galaxies change their shapes within one Hubble time. And much more. Examine a new kinematical classification scheme of the unmasked, dust-penetrated near-infrared images of spiral galaxies. This volume contains over 80 refereed contributions (including 18 in-depth keynote review articles), 40 pages of questions and answers, a panel discussion transcribed from tape and 24 colour plates. The volume is unique in that contributions from both high and low redshift experts are represented at a level readily accessible to postdoctoral students entering the exciting world of morphology - whether it be of the local, or more distant, Universe.




A Galaxy of Things


Book Description

A Galaxy of Things explores the ways in which all puppets, masks, makeup-prosthetic figures are "material characters," using iconic Star Wars characters like Yoda and R2-D2 to illustrate what makes them so compelling. As an epic franchise, Star Wars has been defined by creatures, droids, and masked figures since the original 1977 movie. Author Colette Searls, a theatre director and expert in puppetry studies, uncovers how non-humans like Chewbacca, semi-humans like Darth Maul, and even concealed humans like Boba Fett tell meaningful stories that conventional human characters cannot. Searls defines three powers that puppets, masked figures, and other material characters wield—distance, distillation, and duality—and analyzes Star Wars’ most iconic robots and aliens to demonstrate how they work across nearly a half-century of live-action films. Yoda and "Baby Yoda"—two of popular culture’s greatest puppets—use these qualities to transform their human companions. Similarly, Darth Vader’s mask functions as a performing object driving mystery and suspense across three film trilogies. The power of material characters has also been wielded in problematic ways, such as stereotypes in the representation of service droids and controversial creatures like Jar Jar Binks. Bringing readers forward into the first Star Wars live-action streaming series, the book also explores how the early 2020s stories centered material characters in particularly meaningful, often redemptive ways. A Galaxy of Things is an accessible guide to puppets, masks, and other material characters for students and scholars of theatre, film, puppetry, and popular culture studies. It also offers useful perspectives on non-human representation for researchers in object-oriented ontology, posthumanism, ethnic studies, and material culture.




Masks of the Universe


Book Description

From the animistic world of the primitives of Newton's well-oiled clockwork to the warp and weave of Einsteinian spacetime, Harrison shows how every universe has been the ultimate universe--until a better one came along. Harrison also tours our latest version of the universe, deftly charting the strange, tiny cosmos of subatomic particles and the vast, limitless ocean of stars and galaxies. Throughout, the author enlivens his discussions with the words and thoughts of a dazzling array of renowned scientists, poets, and philosophers both past and present. He includes a number of carefully chosen illustrations--from an engraving of Dante's conception of the universe to a simple space-and-time diagram. ISBN 0-02-948780-3: $18.95.




Measuring Galaxy Bias of Emission Line Galaxies with a Mask


Book Description

Emission line galaxies are fast becoming the most well-studied studied objects at high redshift, and understanding their relationship to the distribution of underlying matter is vital to making cosmological measurements with these sources. We present a measurement of galaxy bias for a sample of O[III] [lambda]5007-selected galaxies between 1.9
