This all-purpose star atlas is the first of its kind devoted to observing the Herschel objects with binoculars and telescopes. It displays over 2500 of the most visually attractive star clusters, nebulae and galaxies that were discovered by Sir William, Caroline and Sir John Herschel. Covering the entire sky from the North to the South Celestial Pole, and showing all 88 constellations, it is also a general sky atlas showing variable, double and multiple stars, and the Milky Way. Written by experienced observer James Mullaney and illustrated by renowned celestial cartographer Wil Tirion, this is a magnificent 'celestial roadmap' to some of the finest deep-sky showpieces. Spiral bound and printed in red-light friendly colors for use at a telescope, with color-coded symbols for easy recognition and identification, this is a must-have observing reference for all amateur observers. Additional resources, including a target list ordered by Herschel designation, are available to download from www.cambridge.org/9780521138178.
The first and only atlas of physical double stars, with charts by celestial cartographer Wil Tirion.
"A desolate landscape, wracked with upheaval, the uncanny nature of a place once so familiar. A revelation of what was formerly undisclosed, the harbingers of apocalypse are edging ever closer..." The wasteland of abandoned memories, the end of the world or a chance for a new beginning. Be it a personal apocalypse, or one of great cataclysm, the stories that arise from the rubble are tales of aftermath and tales of survival. Bridging the gap between Science Fiction and Horror, the gothic overtones of the apocalyptic imagination are explored to their full extent in these short stories. "After the Fall: Tales of the Apocalypse" is a collection of twenty short stories from some of the best up-a...
This prize-winning Ph.D. thesis by Chris Harrison adopts a multi-faceted approach to address the lack of decisive observational evidence, utilising large observational data sets from several world-leading telescopes. Developing several novel observational techniques, Harrison demonstrated that energetic winds driven by Active Galactic Nuclei (AGN) are found in a large number of galaxies, with properties in agreement with model predictions. One of the key unsolved problems in astrophysics is understanding the influence of AGN, the sites of growing supermassive black holes, on the evolution of galaxies. Leading theoretical models predict that AGN drive energetic winds into galaxies, regulating the formation of stars. However, until now, we have lacked the decisive observational evidence to confirm or refute these key predictions. Careful selection of targets allowed Harrison, to reliably place these detailed observations into the context of the overall galaxy population. However, in disagreement with the model predictions, Harrison showed that AGN have little global effect on star formation in galaxies. Theoretical models are now left with the challenge of explaining these results.
