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 ...

On angular scales of the order of one degree, an analysis of data from the Saskatoon experiment 43 set the first upper limit (25 µK at 95% confidence for l ≈ 75); this limit is also noteworthy ...

Here we describe the Degree Angular Scale Interferometer (DASI), an array of radio telescopes, which for the past two years has conducted polarization-sensitive observations of the CMB from the ...
