The GMT mirror casting was a huge success
August 27, 2013
Dear GMT partners:

A warm thank you to all of you for making Friday's GMT Partner Retreat a success, and for all of your ongoing support and encouragement for the project. With the third mirror now in production, we are continuing to reach major milestones, and to keep on target for our construction start in early 2014.

The mirror casting was a huge success, as was the media interest. The casting story was picked up by the CBS evening news last evening.

A video made by Robin and Todd Mason (of Journey to Palomar fame) was sent to the press in advance of the mirror casting. It was picked up by NPR and now has over 19,000 hits and is still climbing.

The story was also picked up by the LA Times, Arizona Daily Wildcat, Canberra Times, Houston Chronicle, Washington Post, CNN, and USA Today, amongst many others.
Overall, a huge success.

With best regards,
Wendy

Paolo Privitera receives $225,000 in collaborative seed grant
August 7, 2013
Three teams of University and Fermi National Accelerator Laboratory researchers - one group that includes a researcher from Argonne National Laboratory - recently received $225,000, collectively, in Strategic Collaborative Initiative (SCI) seed grants from the University following a rigorous competition managed by Fermilab and the University. One of the teams received second-year funding. The FY 2013 recipients include:

* "An advanced, five orders of magnitude dynamic range, wafer-scale pixel system for X-ray science", University of Chicago Investigator: John Keith Moffat, Louis Block Professor of Biochemistry and Molecular Biology; Fermilab Investigator: Grzegorz Deptuch, Engineer IV, Particle Physics Division; Argonne Investigator: Robert Bradford, Assistant Physicist, X-ray Science Division.

* "Development of low noise electronics for the first direct Dark Matter search using CCDs" (funded for a second year), University of Chicago Investigator: Paolo Privitera, Professor of Astronomy and Astrophysics; Fermilab Investigators: Juan Estrada, Scientist II, Participles Physics Division and Gustavo Cancelo, Engineer IV, Scientific Computing Division.

* "SCENE: SCintillation Efficiency of Noble Elements", University of Chicago Investigator: Luca Grandi, Assistant Professor of Physics; Fermilab Investigator: Stephen Pordes, Scientist II, Particle Physics Division.

The Strategic Collaborative Initiatives Program began in 2006 when the University renewed its contract with the DOE to manage Argonne. The SCI program includes collaborative research projects, strategic joint appointments, and joint institutes. The University extended the program to Fermilab when it became co-manager of the lab in 2007.

Detection of B-mode Polarization in the Cosmic Microwave Background with Data from the South Pole Telescope
July 23, 2013
Gravitational lensing of the cosmic microwave background generates a curl pattern in the observed polarization. This "B-mode" signal provides a measure of the projected mass distribution over the entire observable Universe and also acts as a contaminant for the measurement of primordial gravity-wave signals. In this letter we present the first detection of gravitational lensing B modes, using first-season data from the polarization-sensitive receiver on the South Pole Telescope (SPTpol). We construct a template for the lensing B-mode signal by combining E-mode polarization measured by SPTpol with estimates of the lensing potential from a Herschel-SPIRE map of the cosmic infrared background. We compare this template to the B modes measured directly by SPTpol, finding a non-zero correlation at 7.7 sigma significance. The correlation has an amplitude and scale-dependence consistent with theoretical expectations, is robust with respect to analysis choices, and constitutes the first measurement of a powerful cosmological observable.

Congratulations to Krista Martocci for successfully defending her PhD dissertation on "Dynamo Action in Taylor Couette Flow."

"Krista has studied the development of turbulence and dynamo action by the Magneto-Rotational Instability in centrifugally stable, differentially rotating systems. Her results have direct applications to the problem of the origin of turbulence and enhanced angular momentum transport in astrophysical accretion discs."
- Fausto Cattaneo, PhD advisor

Krista has received a postdoctoral researcher position at the Center for Magnetic Self Organization, the University of Chicago.

Congratulations to Randy Landsberg!
July 16, 2013
Our very own Randy Landsberg was a crew member of the Providence Team that finished in 1st place overall in this year's race to Mackinac. This is the second time this team has finished first overall in the race of 333 miles distance, nearly an hour ahead of the 2nd place boat. See 105 Race to Mackinac for the final results.

The Chicago Yacht Club Race to Mackinac is run by the Chicago Yacht Club, first run in 1898. It is one of the longest fresh-water races in the world, with hundreds of boats entering the race each year. The race starts off the mouth of the Chicago River in Chicago, crosses Lake Michigan, barely enters Lake Huron, and finishes in the Round Island Channel, off Mackinac Island, Michigan. The race course runs 333 miles.

Jacob Bean Awarded the First HST Treasury Program for Exo-planet Observations
June 14, 2013
Assistant Professor Jacob Bean has been awarded a historic 150 orbits of Hubble Space Telescope (HST) time for observations of exoplanet atmospheres. His team's research program seeks to improve our understanding of the nature and origins of planets through a comprehensive study of the composition, thermal structure, and dynamics of extrasolar planetary atmospheres. The HST observations will probe the atmospheres of eight exoplanets ranging in mass from (0.04 to 10 M_Jup) using the transit technique to precisely measure their transmission and emission spectra. This is the largest Hubble program ever for exoplanets, and the first to be deemed a "Treasury Program" (i.e., designed to create datasets of lasting value to the HST project that should be obtained before HST ceases operations). Graduate student Laura Kreidberg and postdoc Kevin Stevenson will be leading the data analysis, and observations will begin in October 2013.
