Sarah was invited to present a colloquium talk at NRAO, Socorro, NM. The abstract of the talk is provided here.
Matt attended the 2013 Anomalous Microwave Emission Workshop in Pasadena, CA.
Kiruthika and Sarah attended a software meeting at the Robert C. Byrd Green Bank Telescope (GBT), Green Bank, West Virginia in August, 2013. This meeting was aimed at working out the software needs once Argus is fielded at the GBT, to enable astronomers to observe with the focal plane array.
Stephen Osborne after graduation has started a new job with KLA-Tencor. Congratulations and all the best Stephen!
In collaboration with scientists at JPL and NGC, Patricia presented her recent measurements of three different InP 35 nm gate-length High Electron Mobility Transistor (HEMT) Low Noise Amplifiers (LNAs) at the 2013 International Microwave Symposium in Seattle, WA. The measurements included a record low spot noise temperature for cryogenic HEMT LNAs: 46 K at 152 GHz. The conference paper, “Low Noise Amplifiers for 140 GHz Wide-Band Cryogenic Receivers,” will be available online soon. Abstracts can be found in the conference program.
The Church group members attended the physics department commencement ceremony on June 16, 2013 to celebrate the graduating students. Congratulations Patricia, Stephen, and Javier!
We had our preliminary and critical design reviews (PDR/CDR) for Argus at Stanford, CA on Apr 20-22, 2013. The goal of the PDR/CDR was to have end-to-end design review, and freeze interfaces between sub-assemblies, where possible. Argus is on a very tight schedule, with commissioning to start in Nov, 2014. So, we identified and addressed as many of the schedule risk items as possible at the meeting.
Matt, Kiruthika, and Sarah attended the conference “Infrared and Submillimeter Probes of Gas in Galaxies: From the Milky Way to the Distant Universe“. This conference was aimed at exploring the formation and evolution of galaxies using gas tracers. The conference was hosted by IPAC in Pasadena, on March 17-20, 2013.
An overview of the Argus focal plane array was presented as a poster at the NRAO workshop on “The Interstellar Medium in High Redshift Galaxies Comes of Age“. This workshop focussed on the study of molecular emission at high redshift. The poster is provided here. The short paper Argus that was published is provided here.
