Book Description
This book introduces an analytic method to describe the shadow of black holes. As an introduction, it presents a survey of the attempts to observe the shadow of galactic black holes. Based on a detailed discussion of the Plebański–Demiański class of space-times, the book derives analytical formulas for the photon regions and for the boundary curve of the shadow as seen by an observer in the domain of outer communication. It also analyzes how the shadow depends on the motion of the observer. For all cases, the photon regions and shadows are visualized for various values of the parameters. Finally, it considers how the analytical formulas can be used for calculating the horizontal and vertical angular diameters of the shadow, and estimates values for the black holes at the centers of our Galaxy near Sgr A* and of the neighboring galaxy M87.

Book Description
A sci-fi thrill ride—incredible action, inventive world-building, deadly humor, and more—for fans of movie classics such as Blade Runner and Mad Max! This is the companion to Invisible Sun and Black Hole Sun, which Suzanne Collins, the author of The Hunger Games, called "imaginative and action-packed." Characters return, new characters are introduced, and the action never stops. Readers embraced the first two books in acclaimed author David Macinnis Gill's trilogy about Durango, Mimi (his nano-implant with a biting wit), and Vienne (his second-in-command), calling the books non-put-downable, thrilling, funny, and totally satisfying. A surefire bet for fans of dystopian sci-fi, from The Hunger Games to Battlestar Galactica. Cinematic action, rapid-fire dialogue, a futuristic setting on a terraformed Mars, and tragic romance—Shadow on the Sun is an unstoppable adrenaline rush!

Book Description
Black holes entered the world of science fiction and films in the 1960s, and their popularity in our culture remains today. The buzz surrounding black holes was and is due, in large part, to their speculative nature. It is still difficult for the general public to determine fact versus fiction as it pertains to this terrifying idea: something big enough to swallow anything and everything in close proximity, with a gravitational force so strong that nothing, including light, can escape. In the fall of 2015, scientists at the Laser Interferometry Gravitational-Wave Observatory (LIGO) detected the first sounds from black holes, brought to earth by the gravitational waves that emitted from the merging of two black holes 1.4 billion light years away in space. This confirmed the existence of gravitational waves, which Albert Einstein predicted in 1916. In the spring of 2017, physicists and astronomers who were working on the Event Horizon Telescope (EHT) project captured the first image of a black hole. This was the supermassive black hole hosted by the galaxy M87 in the constellation Virgo, 53 million light years away, and the image shows the shadow the black hole casts upon the bright light surrounding it. In this book, John Moffat shares the history of black holes and presents the latest research into these mysterious celestial objects, including the astounding results from gravitational wave detection and the shadow of the black hole.

Book Description
The International Bestseller On April 10, 2019, award-winning astrophysicist Heino Falcke presented the first image ever captured of a black hole at an international press conference—a turning point in astronomy that Science magazine called the scientific breakthrough of the year. That photo was captured with the unthinkable commitment of an intercontinental team of astronomers who transformed the world into a global telescope. While this image achieved Falcke’s goal in making a black hole “visible” for the first time, he recognizes that the photo itself asks more questions for humanity than it answers. Light in the Darkness takes us on Falcke’s extraordinary journey to the darkest corners of the universe. From the first humans looking up at the night sky to modern astrophysics, from the study of black holes to the still-unsolved mysteries of the universe, Falcke asks, in even the greatest triumphs of science, is there room for doubts, faith, and a God? A plea for curiosity and humility, Light in the Darkness sees one of the great minds shaping the world today as he ponders the big, pressing questions that present themselves when we look up at the stars.

Book Description
In Black Hole Chasers, award-winning investigative journalist Anna Crowley Redding presents the riveting true story of one of the most inspiring scientific breakthroughs of our lifetime—the Event Horizon Telescope team's reveal of the first image of a super massive black hole. In April 2019, the Event Horizon Telescope Team unveiled the first ever image of a super massive black hole. This inspiring scientific breakthrough took years of hard work, innovative thinking, and a level of global cooperation never seen before. The challenge was immense. The goal was impossible. They would need a telescope as big as the earth itself. The technology simply didn’t exist. And yet, a multi-national team of scientists was able to show the world an image of something previously unseeable. Based off extensive research and hours interviews with many of the team's ground-breaking scientists, physicists, and mathematicians, Black Hole Chasers is a story of unique technological innovation and scientific breakthroughs, but more importantly, it's a story of human curiosity and triumph.
