The PFC will welcome 3 new Fellows in the Autumn of 2013
Tim Linden will join the KICP as a Fellow after finishing up his degree at UC Santa Cruz. Tim's research focuses on the indirect detection of particle dark matter with a particular interest in separating potential dark matter signals from astrophysical backgrounds.

Chris Sheehy will join the KICP as a Fellow after receiving his degree from the UofC. He has spent significant time at the University of Minnesota as well. Chris is a CMB experimentalist who has worked extensively on the search for B-mode polarization on the BICEP and Keck Array experiments. At the KICP, Chris will continue on those experiments while contributing his expertise to the SPT project.

Austin Joyce will join us as a joint EFI/McCormick and KICP Fellow. Austin is currently at Penn where his research has focused on applications of quantum field theory to cosmology. Areas that he has been particularly active in are formal aspects of inflationary universe theories and investigations of galileon theories to explain the late time acceleration of the Universe.

Pizza with Professors

Pizza with Professors
On February 19th, the Society of Women in Physics(SWIP) and the KICP joined forces to host "Pizza with Professors," a dinner and discussion about the joys and stresses of pursuing a career in physics. Professors and post-doctoral fellows from the KICP joined faculty from the Physics department in speaking with around 50 undergraduate Physics majors. The event was held in the Kersten Family Atrium of the University's Gordon Center for the Integrative Sciences. Participants left with a better appreciation of what a career in physics or a related field ultimately requires.

PFC postdocs and graduate students at the "Expanding Your Horizons" symposium
Two KICP postdocs Ali Vanderveld and Elise Jennings as well as Ph.D. students Abigail Crites, Alissa Bans and Brittany Kamai took part in the "Expanding Your Horizons" (EYH) outreach event.
"Expanding Your Horizons" is a one day symposium for middle school girls showing them the exciting and diverse experiences science, technology, engineering and math (STEM) careers have to offer. Volunteers from the Chicago STEM community organize short, hands-on workshops to directly engage with the girls at a critical time in their development. EYH is a nationally recognized program and the University of Chicago is proud bring it to the Windy City!

Congratulations to Dr. Matthew Becker!
Congratulations to Matthew Becker for successfully defending his PhD dissertation on "CALCLENS: Weak Lensing Simulations for Large-Area Sky Surveys and Second-Order Effects in Cosmic Shear Power Spectra."

"Matt's thesis work, in which he has developed a novel algorithm of computing distorsions of galaxy images using data from cosmological simulations, significantly advances our ability to make realistic theoretical predictions for upcoming wide area surveys aiming to map matter distribution in the universe on large scales."
- Andrey Kravtsov, PhD advisor

Matthew has received a Postdoctoral Scholar in the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University.

Congratulations to Dr. Lindsey Bleem!
Congratulations to Lindsey Bleem for successfully defending her PhD dissertation on "A Multi-Wavelength Study of Optically Selected Galaxy Clusters from the Blanco Cosmology Survey."

"After making critical contributions to every aspect of the 10m South Pole Telescope (SPT) program, from testing the initial detectors at Chicago, optimizing the performance of the telescope at the South Pole, analyzing the cosmic microwave background data and leading the optical follow up observations and analysis, Lindsey's thesis has taken the first major step in the joint analysis of the SPT and optical survey data sets. This work thoroughly explores the Sunyaev-Zel'dovich signal of an optical selected sample of galaxy clusters, laying the groundwork and identifying the challenges for obtaining precision dark energy constraints from the much anticipated joint analysis of the SPT data with the upcoming optical data from the Dark Energy Survey."
- John Carlstrom, PhD advisor

Lindsey has received a Director's Fellowship at the Argonne National Laboratory.

Kyle Story has been selected for a Dissertation Year Fellowship
Kyle Story has been selected for a William Rainey Harper Dissertation Fellowship for the 2013-14 academic year.

The intent of the award is two-fold: to recognize significant achievement and to facilitate completion of the doctoral degree. This award, one of the University of Chicago's highest honors, is given in recognition of your record of achievement and professional promise. The Harper Dissertation Fellowship provides a stipend of $10,000. The stipend will be disbursed in three equal parts at the start of the autumn, winter, and spring quarters.

Daniel Grin will bring his NSF Astronomy and Astrophysics Postdoctoral Fellowship to the PFC
Daniel Grin is interested in a variety of topics in theoretical cosmology and astrophysics, including cosmological recombination, inflationary perturbations, distortions of the CMB blackbody, isocurvature fluctuations, primordial/non-primordial CMB non-Gaussianity and its optimal statistical estimation, the cosmic microwave background more generally, axions, dark matter halo profiles, dynamical processes near the galactic center, resonant friction/relaxation, nonstandard thermal histories for the early universe, modifications to general relativity, gravitational lensing, and Lyman limit absorbers.

Daniel received an undergraduate degree in Physics from Princeton University in 2003, a Master of Studies degree in Philosophy from Oxford in 2004, and his Ph.D. in astrophysics from the California Institute of Technology in 2010, after which he has been a 3-year postdoctoral member at the Institute for Advanced Study in Princeton, NJ. As an NSF fellow Daniel will continue his research program and develop an astronomy outreach effort for Chicago senior citizens. When not doing physics, Daniel enjoys playing the cello, spending time outdoors, reading, exploring Chicago, and spending time with his wife and daughter.

Congratulations to Dr. Christopher Williams!
Congratulations to Christopher Williams for successfully defending his PhD dissertation on "A Search For Microwave Emission From Cosmic Ray Air Showers."

"The unsolved mystery of ultra-high energy cosmic rays demands a novel approach to the detection of these very rare particles. Chris - a natural-born experimentalist - has made an outstanding contribution with his thesis, by exploring the potential of microwave emission from extensive air showers through a series of careful and accurate measurements. He brought to life MIDAS, an exploratory detector currently taking data at the Pierre Auger Observatory in Argentina, and MAYBE, an electron beam experiment at the Argonne National Laboratory. Measurements performed by these instruments are the most precise of a world-wide campaign to detect microwave emission from cosmic rays."
- Paolo Privitera, PhD advisor

Christopher has received a fellow position at the Kavli Institute for Particle Astrophysics and Cosmology (Stanford).

Detection of B-mode Polarization in the Cosmic Microwave Background with Data from the South Pole Telescope
July 23, 2013
FIG. 1: (Left panel): Wiener- filtered E-mode polarization measured by SPTpol at 150 GHz. (Center panel): Wiener- ltered CMB lensing potential inferred from CIB fluctuations measured by Herschel at 500 μm. (Right panel): Gravitational lensing B-mode estimate synthesized using Eq. (1). The lower left corner of each panel indicates the blue(-)/red(+) color scale.
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.Learn more >>
