'This is a nicely produced book which should appeal to a wide
readership.'The ObservatoryThis book is about the Dark Energy
Survey, a cosmological experiment designed to investigate the
physical nature of dark energy by measuring its effect on the
expansion history of the universe and on the growth of large-scale
structure. The survey saw first light in 2012, after a decade of
planning, and completed observations in 2019. The collaboration
designed and built a 570-megapixel camera and installed it on the
four-metre Blanco telescope at the Cerro Tololo Inter-American
Observatory in the Chilean Andes. The survey data yielded a
three-dimensional map of over 300 million galaxies and a catalogue
of thousands of supernovae. Analysis of the early data has
confirmed remarkably accurately the model of cold dark matter and a
cosmological constant. The survey has also offered new insights
into galaxies, supernovae, stellar evolution, solar system objects
and the nature of gravitational wave events.A project of this scale
required the long-term commitment of hundreds of scientists from
institutions all over the world. The chapters in the first three
sections of the book were either written by these scientists or
based on interviews with them. These chapters explain, for a
non-specialist reader, the science analysis involved. They also
describe how the project was conceived, and chronicle some of the
many and diverse challenges involved in advancing our understanding
of the universe. The final section is trans-disciplinary, including
inputs from a philosopher, an anthropologist, visual artists and a
poet. Scientific collaborations are human endeavours and the book
aims to convey a sense of the wider context within which science
comes about.This book is addressed to scientists, decision makers,
social scientists and engineers, as well as to anyone with an
interest in contemporary cosmology and astrophysics.Related Link(s)
