2015 Goldhaber Prize Winners

November 25, 2014
Graduate students Dennis Huang, Siyuan Sun, Bo Liu, and Shu-Heng Shao (pictured above, clockwise from top left) are the winners of the 2015 Maurice and Gertrude Goldhaber Prize. The prize is awarded annually by the department to its most outstanding current PhD students after they pass their qualifying exams, based on their accomplishments, creativity, and innovative approaches to research, as determined by a vote of the faculty.

Observation of an Excited Bc+/- Meson State with the ATLAS Detector

November 24, 2014

Figure 1: Invariant mass distributions of the reconstructed Bc± → J/ψπ± candidates in 7 TeV data (top) and in 8 TeV data (bottom). The data are represented by the points with error bars (statistical only). The solid line is the projection of the results of the unbinned maximum likelihood fit to all candidates in the mass range 5620–6820 MeV. The dashed line is the projection of the background component of the same fit. [From G. Aad et al.

A microfabricated array of TES bolometers

Figure 8:An example of a microfabricated array of TES bolometers, an 88 pixel, dual polarization TES bolometer array made at NIST for the SPTpol experiment. TES detectors are micro-machined from thin films deposited on silicon wafer substrates which means TES-based devices are fundamentally fabricated as arrays. [from K.N.

High-Z Supernova Search Team

Professor Christopher Stubbs is a member of the High-Z Supernova Search Team which, together with the the Supernova Cosmology Project, have been awarded the 2015 Breakthrough Prize in Fundamental Physics "for the most unexpected discovery that the expansion of the universe is accelerating, rather than slowing as had been long assumed."
