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 ...

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 ...

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

A 180-degree angle means that there is no difference, which is fairly true for CRT and plasma screens. However, viewing angles differ between LCD and front and rear-projection screens.

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 ...
