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.

Blazars (also known as BL Lac objects), first discovered in 1978, are unusually energetic objects in the extragalactic universe. About 200 are known or suspected. They are radio sources with highly variable optical and radio emission, as well as high polarisation, and their optical spectra normally have no distinguishable features. It is generally accepted that they belong to that class of galaxies with active galactic nuclei, which are presumed to be driven by infall of matter to a supermassive black hole. In this book researchers give a complete summary of the observations of blazars and the theoretical interpretation. A comprehensive listing of confirmed and candidate objects is included. Mechanisms in which the variability can arise from shocks and relativistic jets are discussed. There are at least four different answers given to the question: what is a blazar? This book is a complete overview of the violent activity observed in these extreme active galactic nuclei.

These proceedings collect the selected contributions of participants of the First Karl Schwarzschild Meeting on Gravitational Physics, held in Frankfurt, Germany to celebrate the 140th anniversary of Schwarzschild's birth. They are grouped into 4 main themes: I. The Life and Work of Karl Schwarzschild; II. Black Holes in Classical General Relativity, Numerical Relativity, Astrophysics, Cosmology, and Alternative Theories of Gravity; III. Black Holes in Quantum Gravity and String Theory; IV. Other Topics in Contemporary Gravitation. Inspired by the foundational principle ``By acknowledging the past, we open a route to the future", the week-long meeting, envisioned as a forum for exchange between scientists from all locations and levels of education, drew participants from 15 countries across 4 continents. In addition to plenary talks from leading researchers, a special focus on young talent was provided, a feature underlined by the Springer Prize for the best student and junior presentations.

SMERSH is the award-winning account of the top-secret counterintelligence organisation that dealt with Stalin's enemies from within the shadowy recesses of Soviet government. As James Bond's nemesis in Ian Fleming's novels, SMERSH and its operatives were depicted in exotic duels with 007, rather than fostering the bleak oppression and terror they actually spread in the name of their dictator. Stalin drew a veil of secrecy over SMERSH's operations in 1946, but that did not stop him using it to terrify Red Army dissenters in Leningrad and Moscow, or to abduct and execute suspected spooks - often without cause - across mainland Europe. Formed to mop up Nazi spy rings at the end of the Second World War, SMERSH gained its name from a combination of the Russian words for 'Death to Spies'. Successive Communist governments suppressed traces of Stalin's political hit squad; now Vadim Birstein lays bare the surgical brutality with which it exerted its influence as part of the paranoid regime, both within the Soviet Union and in the wider world. SMERSH was the most mysterious and secret of organisations - this definitive and magisterial history finally reveals truths that lay buried for nearly fifty years.

Psychological Science: The Curious Mind, by award-winning authors and professors Catherine A. Sanderson and Karen Huffman, introduces 21st-century, digital-native students to the fascinating field of psychology. This new program emphasizes the importance of developing scientific literacy and an understanding of research and research methods. The program uses an inviting why-focused framework that taps into students' natural curiosity, incorporating active learning and real-life application to engage students. Psychological Science: The Curious Mind embraces the guidelines released by the American Psychological Association (APA)'s Introductory Psychology Initiative (IPI) in 2021. It provides an excellent framework for instructors who want to implement those guidelines in their Introductory Psychology courses, and it provides students with the content and motivation to achieve the course's ultimate outcome: an enduring, foundational understanding of psychological science.

The Geheime Feldpolizei (Secret Field Police) was the political police force of the German Army during World War II. Its members were drawn from both the regular German police, including detectives, and various Nazi security organizations. The goals of the GFP were numerous and included protecting important political and military leaders; investigating black market activities as well as acts of sabotage and espionage; locating deserters; examining anti–German activists and hunting down partisans. While performing these duties, GFP members immersed themselves in criminal activities. This book focuses on the function of the GFP in Greece compared to that of the GFP elsewhere in Europe.

This book discusses the active and passive radar cross section (RCS) estimation and techniques to examine the low observable aerospace platforms. It begins with the fundamentals of RCS, followed by the dielectric, magnetic and metamaterials parameters of the constituent materials and then explains various methods and the emerging trends followed in this area of study. The RCS estimation of phased array including the mutual coupling effect is also presented in detail in the book. The active RCS reduction is carefully touched upon through the performance of phased arrays, sidelobe cancellers and mitigation of multipath effect. Providing information on various adaptive algorithms like least mean square (LMS), recursive least square (RLS) and weighted least square algorithms, the authors also mention the recent developments in the area of embedded antennas, conformal load bearing antenna, metamaterials and frequency selective surface (FSS) based RCS reduction.
