After describing cosmic gamma-ray production and absorption, the instrumentation used in gamma-ray astronomy is explained. The main part of the book deals with astronomical results, including the somewhat surprising result that the gamma-ray sky is continuously changing.
This book provides a theoretical and observational overview of the state of the art of gamma-ray astrophysics, and their impact and connection with the physics of cosmic rays and neutrinos. With the aim of shedding new and fresh light on the problem of the nature of the gamma-ray sources, particularly those yet unidentified, this book summarizes contributions to a workshop that continues today.
The book reviews the present status of understanding the nature of the most luminous objects in the Universe, connected with supermassive black holes and supermassive stars, clusters of galaxies and ultraluminous galaxies, sources of gamma-ray bursts and relativistic jets. Leading experts give overviews of essential physical mechanisms involved, discuss formation and evolution of these objects as well as prospects for their use in cosmology, as probes of the intergalactic medium at high redshifts and as a tool to study the end of dark ages. The theoretical models are complemented by new exciting results from orbital and ground-based observatories such as Chandra, XMM-Newton, HST, SDSS, VLT, Keck, and many others.
What is it like to spend a lifetime doing research in a wide variety of fields in the physical sciences? Studying distant planets, binary stars, neutron stars, stellar mass black holes and active galaxies using optical and near-infrared ground-based telescopes. Designing and constructing equipment as a member of international teams studying the high-energy X-ray emissions from many of these objects. Flying these detectors on short duration sounding rocket flights, utilising huge balloons to carry experiments to high altitude, or installing them on long duration satellite missions. Being a scientist engaged in fieldwork studying the physical properties of the world’s oceans, or the sea ice and glaciers around the coastline of Antarctica. This lifetime involved living in the UK and Australia for many years, with a four-year interlude in the USA, as well as working in or visiting many other countries. How lucky can you get? This book describes numerous projects in an unusually diverse range of research areas – the fun and adventure of STEM activities – without getting into excessive technical or specialist detail.
This book addresses graduate students in the first place and is meant as a modern compendium to the existing texts on black hole astrophysics. The authors present in pedagogically written articles our present knowledge on black holes covering mathematical models including numerical aspects and physics and astronomical observations as well. In addition, in their write-up of a panel discussion the participants of the school address the existence of black holes consenting that it has by now been verified with certainty.
The twentieth century was the era of "big science." Driven by strategic rivalries and fierce economic competition, wealthy governments invested heavily in national science establishments. Direct funding for institutions like the National Science Foundation and high-visibility projects, such as the race to the moon, fueled innovation, growth, and national prestige. But the big science model left poorer countries out in the cold. Today the organization of science is undergoing a fundamental transformation. In T he New Invisible College, Caroline Wagner combines quantitative data and extensive interviews to map the emergence of global science networks and trace the dynamics driving their growth...
Science and the Bible do not contradict one another. The author shows that the plain and literal text of the Bible is in perfect harmony with even the latest findings of mainstream science. You need not compromise either your faith or your intellect.
This book provides the first comprehensive historical account of the evolution of scientific traditions in astronomy, astrophysics, and the space sciences within the Max Planck Society. Structured with in-depth archival research, interviews with protagonists, unpublished photographs, and an extensive bibliography, it follows a unique history: from the post-war relaunch of physical sciences in West Germany, to the spectacular developments and successes of cosmic sciences in the second half of the 20th century, up to the emergence of multi-messenger astronomy. It reveals how the Society acquired national and international acclaim in becoming one of the world’s most productive research organizations in these fields.
