Intuitively, we all know that when we see an image of an object, it could either be large and far away or small and close by. Only with a three-dimensional measurement can we actually know what's ...
Despite recent successes in attributing most of the extragalactic background light at submillimetre wavelengths to known galaxy populations through stacking analyses 15,16,17, we have not individually ...
DASI is an interferometric array designed to measure anisotropy in the CMB radiation on angular scales of 1.3–0.2°, corresponding to multipoles l ≈ 140–900. Arrays of telescopes operate as ...
Figure 1. (a) WISE false color image of Pa 30 where blue and green stand for 11 μm emission, and red for 22 μm. Here, the levels of the 22 μm component have been adjusted to enhance the ring-like ...
In a hypertorus model of the Universe, motion in a straight line will return you to your original location, even in an uncurved (flat) spacetime. This multiply connected topology might be able to be ...
Recent data from the cosmic microwave background add further weight to the inflationary big-bang model. But more precise measurements from NASA’s MAP satellite, which is due to be launched this month, ...
Professor Halverson works in experimental cosmology, including observations of the Cosmic Microwave Background (CMB) and mm-wave instrumentation development efforts. His previous experience at Caltech ...
