Written by a carefully selected consortium of researchers working in the field, this book fills the gap for an up-to-date summary of the observational and theoretical status. As such, this monograph includes all used wavelengths, from radio to gamma, the FERMI telescope, a history and theory refresher, and jets from gamma ray bursts. For astronomers, nuclear physicists, and plasmaphysicists.

This AGN textbook includes phenomena based on new results in the X-Ray domain from new telescopes such as Chandra and XMM Newton not mentioned in any other book. Furthermore, it considers also the Fermi Gamma Ray Space Telescope with its revolutionary advances of unprecedented sensitivity, field of view and all-sky monitoring. Those and other new developments as well as simulations of AGN merging events and formations, enabled through latest super-computing capabilities. The book gives an overview on the current knowledge of the Active Galacitc Nuclei phenomenon. The spectral energy distribution will be discussed, pointing out what can be observed in different wavebands and with different physical models. Furthermore, the authors discuss the AGN with respect to its environment, host galaxy, feedback in galaxy clusters, etc. and finally the cosmological evolution of the AGN phenomenon.

A warm, witty memoir of one man’s escape from the city in an unlikely quest to create out of a mountainous Welsh landscape a garden fit for inclusion in the prestigious Yellow Book – the ‘Gardens of England and Wales Open for Charity’ guide – in just one year.It was a derelict smallholding so high up in the Black Mountains of Wales it was routinely lost in cloud. But to Antony Woodward, Tair-Ffynnon was the most beautiful place in the world.Equally ill-at-ease in town and country after too long in London’s ad-land, Woodward bought Tair-Ffynnon because he yearned to reconnect with the countryside he never felt part of as a child. But what excuse could he invent to move there permanently?The solution, he decided, was a garden. In just a year he’d create a garden so special it would be selected for the prestigious Yellow Book – the famous National Gardens Scheme guide to gardens open to the public for charity. It’s an unlikely ambition to entertain in this most unlikely of settings, and one that soon sees Woodward driven by odder and odder compulsions – from hauling a 20-tonne railway carriage up the mountain to making hay with hopelessly antiquated machinery.The path to Woodward’s elusive sense of belonging turns out to be a rocky and winding one, taking in childhood haunts, children’s books and Proustian nostalgia trips. As the family battles gales, mud and Welsh mountain sheep of marble-eyed cunning, not to mention the notoriously fastidious NGS County Organiser, it remains deeply uncertain whether the ‘Not Garden’ and the ‘infinity vegetable patch’ (that grows only stones) will ever make the grade…Warm, thought-provoking and brilliantly funny, this is a memoir of a hopeless romantic with a grandly ludicrous ambition – an ambition to which anyone who’s ever dropped into a garden centre, or opened a packet of seeds, has already succumbed.

Planet by planet, galaxy by galaxy, the inhabited universe has fallen to the alien Xul…This bundle includes the complete Inheritance Trilogy by New York Times bestselling author Ian Douglas.Now only one obstacle stands between them and total domination: the warriors of a resilient race the world-devourers nearly annihilated centuries ago . . .A power vast, ancient, and terrifying, the mighty Xul have lost track of the insignificant humans hundreds of years after devastating their home world—which has enabled the United Star Marines to operate unnoticed and unhindered. A near-autonomous intergalactic policing force, they battle in defense of an Earth they may not live to see again. Now, following the trail of a vanished twenty-fourth-century transport, they are journeying through an unexplored stargate to the edge of an unknown galaxy many light years from their sun. For the last, best, and only chance to defeat the tyrants of the universe may at long last be at hand . . .Includes: Star Strike, Galactic Corps and Semper Human.
