Works

Kaiser has made major contributions to cosmology: *He made the first calculation of the polarization of the
cosmic microwave background In Big Bang cosmology the cosmic microwave background (CMB, CMBR) is electromagnetic radiation that is a remnant from an early stage of the universe, also known as "relic radiation". The CMB is faint cosmic background radiation filling all spac ...
(Kaiser 1983); *Explained the higher bias of cluster galaxies relative to the matter field (Kaiser 1984); *Made a detailed calculation of the statistics of density peaks in the primordial Universe (Bardeen, Kaiser, Silk & Szalay 1986); *Introduced the mathematics of
redshift-space distortions Redshift-space distortions are an effect in observational cosmology where the spatial distribution of galaxies appears squashed and distorted when their positions are plotted as a function of their redshift rather than as a function of their distan ...
(Kaiser 1987); *Computed the cosmic

using excursion set theory (Bond, Cole, Efstathiou & Kaiser 1991); *First explained the departures of
galaxy cluster A galaxy cluster, or a cluster of galaxies, is a structure that consists of anywhere from hundreds to thousands of galaxies that are bound together by gravity, with typical masses ranging from 1014 to 1015 solar masses. They are the second-l ...
scaling relations from simple self-similar models (Kaiser 1991); and *Performed the first inversion of shear maps from
weak gravitational lensing While the presence of any mass bends the path of light passing near it, this effect rarely produces the giant arcs and multiple images associated with strong gravitational lensing. Most lines of sight in the universe are thoroughly in the weak l ...
