Birthday: April 25, 1935
Biography: A Canadian-American astrophysicist and cosmologist known for his contributions to the Big Bang theory and cosmic structure formation.
Accomplishments:
Cosmic Microwave Background (1965): Contributed to the prediction and understanding of the CMB.
Dark Matter and Dark Energy: Researched the role of dark matter and dark energy in the universe.
Large-Scale Structure of the Universe: Studied the formation and distribution of galaxies and galaxy clusters.
Nobel Prize in Physics (2019): Awarded for theoretical discoveries in physical cosmology.
Books on Cosmology: Authored several foundational textbooks on cosmology.
Peebles contributed to the theoretical prediction and subsequent understanding of the Cosmic Microwave Background (CMB), the afterglow radiation from the Big Bang, which provides a snapshot of the early universe.
Peebles conducted pioneering research on the nature and role of dark matter and dark energy, which constitute most of the universe's mass-energy content and influence its expansion and structure.
Peebles studied the formation and distribution of galaxies and galaxy clusters, helping to develop the theoretical framework for understanding the large-scale structure of the universe.
Peebles was awarded the Nobel Prize for his theoretical discoveries in physical cosmology, which have profoundly shaped our understanding of the universe's history and structure.
Peebles authored several seminal textbooks on cosmology, including "Physical Cosmology" and "Principles of Physical Cosmology," which have been essential resources for generations of cosmologists.
