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 ...

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 ...

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 ...

The hot Big Bang might have started our Universe as we know it some 13.8 billion years ago, but there's a piece of it still visible to us today. Because the "bang" happened everywhere at once, there's ...

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 ...

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 ...
