It is, however, possible to approximate the solution:
The cosmic microwave background (CMB, CMBR) is microwave radiation that fills all space. It is a remnant that provides an important source of data on the primordial universe. With a standard optical telescope, the background space between stars and galaxies is almost completely dark. However, a sufficiently … See more Precise measurements of the CMB are critical to cosmology, since any proposed model of the universe must explain this radiation. The CMB has a thermal black body spectrum at a temperature of 2.72548±0.00057 K. … See more The cosmic microwave background was first predicted in 1948 by Ralph Alpher and Robert Herman, in close relation to work performed by Alpher's PhD advisor George Gamow. Alpher and Herman were able to estimate the temperature of the cosmic microwave … See more The cosmic microwave background is polarized at the level of a few microkelvin. There are two types of polarization, called E-modes and B-modes. This is in analogy to See more Raw CMBR data, even from space vehicles such as WMAP or Planck, contain foreground effects that completely obscure the fine-scale structure of the cosmic microwave background. The fine-scale structure is superimposed on the raw CMBR data but … See more The cosmic microwave background radiation is an emission of uniform, black body thermal energy coming from all parts of the sky. The radiation is isotropic to roughly one part in … See more The cosmic microwave background radiation and the cosmological redshift-distance relation are together regarded as the best available … See more Subsequent to the discovery of the CMB, hundreds of cosmic microwave background experiments have been conducted to measure and characterize the signatures of the … See more Web• Co-Lead of CMB-S4 Membership Working Group, Fall 2024-Spring 2024 • Lead editor of the CMB Lensing Chapter of the CMB-S4 Science Book, 2015-2016 • Referee for Physical Review D, JCAP, Astronomy & Astrophysics, Monthly Notices of the Royal Astronomical Society, The Astrophysical Journal FORMER ADVISEES:
