With its clear skies and low humidity, the southwestern United States is an astronomer’s paradise where observatories like Kitt Peak have redefined the art of skywatching. The region is unique in its loose federation of like-minded research outposts and in the quantity and diversity of its observatories—places captured in this unique guidebook. Douglas Isbell and Stephen Strom, both intimately involved in southwestern astronomy, have written a practical guide to the major observatories of the region for those eager to learn what modern telescopes are doing, to understand the role each of these often quirky places has played in advancing our understanding of the cosmos, and hopefully to visit and see the tools of the astronomer up close. For each observatory, the authors describe its history, highlights of its contributions to astronomy—with an emphasis on recent results—and information for visitors. Also included are wide-ranging interviews with astronomers closely associated with each site. Observatories covered range from McDonald in Texas to Palomar in California, with significant outposts in between: Arizona’s Kitt Peak National Observatory southwest of Tucson, the Lowell Observatory in Flagstaff, and the Whipple Observatory outside Amado; and New Mexico’s Very Large Array near Socorro and Sacramento Peak close to Sunspot. In addition to describing these established institutions, they also take a look ahead to the most powerful ground-based telescope in the world just beginning to operate at full power on Mount Graham in Safford, Arizona. With more than three dozen illustrations, Observatories of the Southwest is accessible to amateur astronomers, tourists, students, and teachers—anyone fascinated with the contributions that astronomy has made to deepening our understanding of humanity’s place in the universe, whether exploring the solar system from Lowell Observatory or studying the birth of stars using the army of giant radio telescopes at the Very Large Array. This book aims to inspire visits to these sites by illuminating the major scientific questions being pursued every clear night beneath the dark skies of the Southwest and the amazing machinery that makes these pursuits possible.

,This is the updated, widely revised, restructured and expanded third edition of Léna et al.'s successful work Observational Astrophysics. It presents a synthesis on tools and methods of observational astrophysics of the early 21st century. Written specifically for astrophysicists and graduate students, this textbook focuses on fundamental and sometimes practical limitations on the ultimate performance that an astronomical system may reach, rather than presenting particular systems in detail. In little more than a decade there has been extraordinary progress in imaging and detection technologies, in the fields of adaptive optics, optical interferometry, in the sub-millimetre waveband, observation of neutrinos, discovery of exoplanets, to name but a few examples. The work deals with ground-based and space-based astronomy and their respective fields. And it also presents the ambitious concepts behind space missions aimed for the next decades. Avoiding particulars, it covers the whole of the electromagnetic spectrum, and provides an introduction to the new forms of astronomy becoming possible with gravitational waves and neutrinos. It also treats numerical aspects of observational astrophysics: signal processing, astronomical databases and virtual observatories.

From newborn galaxies to icy worlds and blazing quasars, a behind-the-scenes story of how Palomar Observatory astronomers unveiled our complex universe. Ever since 1936, pioneering scientists at Palomar Observatory in Southern California have pushed against the boundaries of the known universe, making a series of dazzling discoveries that changed our view of the cosmos: quasars, colliding galaxies, supermassive black holes, brown dwarfs, supernovae, dark matter, the never-ending expansion of the universe, and much more. In Cosmic Odyssey, astronomer Linda Schweizer tells the story of the men and women at Palomar and their efforts to decipher the vast energies and mysterious processes that govern our universe. Palomar was the Apollo mission of its era. The first images from the 200-inch George Ellery Hale telescope, commissioned in 1948 as the world's largest, generated as much excitement as images from the moon in 1969 and from the Hubble Space Telescope more recently. So far, Palomar's “Big Eye” and three other telescopes have yielded more than 75,000 telescope-nights of precious data. Schweizer takes readers behind the scenes of scientific discovery, mapping the often chaotic process of detours, dead ends, and serendipitous leaps of insight. Although her focus is on Palomar, she follows threads of discovery across the world to other teams and observatories. Based on more than one hundred interviews and enhanced by research in scientific journals, her account paints a fascinating picture of how discrete insights acquired over decades by researchers in a global community cascade, collide, and finally coalesce into the discoveries we come to accept as facts.
