This textbook provides an introduction to gravitational lensing,
which has become an invaluable tool in modern astrophysics, with
applications that range from finding planets orbiting distant stars
to understanding how dark matter and dark energy conspired to form
the cosmic structures we see today. 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.
