Principles of Gravitational Lensing begins with Einstein?s prediction that gravity bends light, and shows how that fundamental idea has spawned a rich field of study over the past century. The gravitational deflection of light was first detected by Eddington during a solar eclipse in May 1919, launching Einstein and his theory of relativity into public view. Yet the possibility of using the phenomenon to unlock mysteries of the Universe seemed remote, given the technology of the day. Theoretical work was carried out sporadically over the next six decades, but only with the discovery of the system Q0957+561 in 1979 was gravitational lensing transformed from a curiosity of general relativity into a practical observational tool. This book describes how the three subfields known as strong lensing, weak lensing, and microlensing have grown independently but become increasingly intertwined. Drawing on their research experience, Congdon and Keeton begin with the basic physics of light bending, then present the mathematical foundations of gravitational lensing, building up to current research topics in a clear and systematic way. Relevant background material from physics and mathematics is included, making the book self-contained. The derivations and explanations are supplemented by exercises designed to help students master the theoretical concepts as well as the methods that drive current research. An extensive bibliography guides those wishing to delve more deeply into particular areas of interest. Principles of Gravitational Lensing is ideal for advanced students and seasoned researchers looking to penetrate this thriving subject and even contribute research of their own. 410 0$aAstronomy and Planetary Sciences,$x2366-0082 606 $aAstrophysics 606 $aCosmology 606 $aObservations, Astronomical 606 $aAstronomy?Observations 606 $aGravitation 606 $aAstrophysics and Astroparticles$3https://scigraph.springernature.com/ontologies/product-market-codes/P22022 606 $aCosmology$3https://scigraph.springernature.com/ontologies/product-market-codes/P22049 606 $aAstronomy, Observations and Techniques$3https://scigraph.springernature.com/ontologies/product-market-codes/P22014 606 $aClassical and Quantum Gravitation, Relativity Theory$3https://scigraph.springernature.com/ontologies/product-market-codes/P19070 615 0$aAstrophysics. 615 0$aCosmology. 615 0$aObservations, Astronomical. 615 0$aAstronomy?Observations. 615 0$aGravitation. 615 14$aAstrophysics and Astroparticles. 615 24$aCosmology. 615 24$aAstronomy, Observations and Techniques. 615 24$aClassical and Quantum Gravitation, Relativity Theory. 676 $a523.01 700 $aCongdon$b Arthur B$4aut$4http://id.loc.gov/vocabulary/relators/aut$01065357 702 $aKeeton$b Charles R$4aut$4http://id.loc.gov/vocabulary/relators/aut 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910300539103321 996 $aPrinciples of Gravitational Lensing$92544826 997 $aUNINA
