Halverson, N. W. et al. Degree Angular Scale Interferometer first results: A measurement of the cosmic microwave background angular power spectrum. Astrophys. J. 568, 38–45 (2002) ...

The past several years have seen the emergence of a standard cosmological model, in which small temperature differences in the cosmic microwave background (CMB) radiation on angular scales of the ...

Research Interests: Professor Halverson works in experimental cosmology, including observations of the Cosmic Microwave Background (CMB) and mm-wave instrumentation development efforts. His previous ...

These have been seen in the latest data (see image above). They are also represented as peaks in a graph of the amplitude of temperature fluctuations against angular scale, i.e. how many ripples there ...

New research from India has shown that bifacial perovskite solar cells can achieve a 2% higher power conversion efficiency with a tilt angle of 20 degrees. The scientists also developed a bifacial ...
