Adler After Dark: Bradford Benson, "Unveiling the Dark Universe with the South Pole Telescope"
February 20, 2014 | 6:45 PM | Adler Planetarium
The South Pole Telescope (SPT) is a microwave telescope located at the geographic South Pole, which has been used to make the most-detailed measurements ever of the light left over from the Big Bang, the cosmic microwave background. I will give an overview of the SPT, and how astronomers are using data from the SPT to better understand the "Dark" Universe: a component of the Universe that makes up over 95% of its density, but whose physical origin is still largely mysterious to us.

Statistics Colloquium: Josh Frieman, Fermilab and the University of Chicago, "Probing Cosmic Acceleration with the Dark Energy Survey: Statistical Challenges and Big Data in Cosmology"
March 10, 2014 | 4:00 PM | Eckhart 133, 5734 S. University Avenue
The Nobel Prize in Physics for 2011 was awarded for the discovery that the expansion of the Universe is accelerating. Yet the physical origin of cosmic acceleration remains a mystery. The Dark Energy Survey (DES) aims to address the questions: why is the expansion speeding up? Is cosmic acceleration due to dark energy or does it require a modification of Einstein's General Relativity? DES is addressing these questions by carrying out a cosmological survey of 200 million galaxies over 1/8th of the sky using a new, 570-megapixel, digital camera on a 4-meter telescope in Chile over the next several years. I will overview the DES project, which achieved 'first light' in September 2012 and which just finished its first survey season last month, and present some early results. In the process, I will discuss some of the "Big Data" challenges in processing and analyzing the data and highlight a number of the statistical methods being employed to extract useful cosmological information (machine learning, spatial N-point clustering statistics, cluster-finding algorithms, Bayesian classification, MCMC, etc).

The discovery that the expansion of the Universe is being accelerated by a mysterious force that cosmologists call "Dark Energy" has had an immense impact and is the most exciting area of research in Cosmology today. The 2011 Nobel Prize in physics was awarded to three astronomers who found the first direct evidence of this acceleration by observing the brightness of exploding stars in the Universe. These astonishing observations have ignited a race towards an even bigger discovery - what is Dark Energy? Unravelling the nature of Dark Energy is one of the most important problems facing cosmologists and will answer profound questions about fundamental physics in our Universe.

In these lectures Dr. Jennings will describe the cutting-edge of current research which tries to make sense of Dark Energy and the accelerating expansion. Uncovering the nature of Dark Energy will require exciting cosmic detective work gathering evidence, formulating theories and testing new ideas in the largest laboratory available to us - the Universe. The lectures require no mathematical or scientific background; just bring your curiosity.

Broader Horizons: Kathryn Schaffer, School of the Art Institute of Chicago
April 7, 2014 | 11:00 AM | LASR conference room
Kathryn Schaffer completed her PhD at the University of Washington studying solar neutrino physics after primarily studying philosophy as an undergraduate. She came to Chicago as a KICP Fellow in 2005, working on data analysis for cosmic microwave background observations with the South Pole Telescope (SPT). In 2008, she decided to veer off course from the "research track," and discovered an unusual faculty position at the School of the Art Institute of Chicago (SAIC). Since 2009, she has been full-time faculty at SAIC, teaching physics and cosmology to art and design students. She continues some research work as part of the SPT collaboration and also contributes to data analysis for nuclear non-proliferation research with a group at Los Alamos National Laboratory. She will discuss the unusual career choices she has made, the pros and cons of taking a teaching-centered position (particularly one that involves teaching to non-science students), and some of the insights she has gained about science and science communication from working with and around artists.

Kavli Foundation Webcast: Secrets of the Universe's First Light
April 18, 2014 | 3:00 PM

THE FIRST PROOF that the universe underwent an almost unimaginably fast expansion when it was only a trillionth of a trillionth of a trillionth of a second old has taken the world by storm. This sudden growth spurt was first theorized more than three decades ago. Yet only last month did astrophysicists reveal the first hard evidence that universe swelled from microscopic to cosmic size in less than the blink of an eye - an announcement so huge that some say dwarfs even the discovery of the Higgs boson.

On April 18, two of the scientists who made this groundbreaking discovery will come together for a conversation with two of the pioneering leaders of the field. Together, they will examine the detection of a distinctive, swirling pattern in the universe's first light, what the swirl tells us about that monumental growth spurt, and the many implications on the way we understand the universe around us.

About the Participants

JOHN CARLSTROM leads two experiments that study the universe's first light: the South Pole Telescope in Antarctica and the Sunyaev-Zeldovich Array in California. One of the foremost researchers in this field, Dr. Carlstrom is an expert at extracting information from patterns in light from the early universe. He is the Deputy Director of the Kavli Institute for Cosmological Physics. Dr. Carlstrom is also the S. Chandrasekhar Distinguished Service Professor in Astronomy & Astrophysics and Physics at the University of Chicago.

WALTER OGBURN is a member of the BICEP2 team that made this important discovery. He also conducts work at The Keck Array, a suite of telescopes at the South Pole that also search for twists in the universe's first light. Dr. Ogburn is a postdoctoral researcher at the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University.

MICHAEL TURNER (Moderator) is a theoretical cosmologist who works at the intersection of cosmology and elementary particle physics to understand the origin and evolution of the universe. Renowned for his work on inflationary cosmology, the characteristics of dark energy and the nature of dark matter, Dr. Turner is the Director of the Kavli Institute for Cosmological Physics as well as the Bruce V. and Diana M. Rauner Distinguished Service Professor at the University of Chicago.

ABIGAIL VIEREGG is an active member of the BICEP2 team. In addition, she works on The Keck Array and the ANITA experiment, which studies ultra-high energy cosmic neutrinos.

519th UChicago Convocation: honoring Wendy L. Freedman
June 12, 2014 | 4:30 PM | Quad Club Solarium (2nd floor)
Dear Astronomy & KICP scientists (students, postdocs, faculty, et al)

Please join us in honoring Wendy L. Freedman who will be receiving an Honorary of Doctor of Science from the University of Chicago this upcoming 519th Convocation.

Wendy L. Freedman, a world leader in astronomy and cosmology, will receive a Doctor of Science honorary degree. Freedman is the Crawford H. Greenewalt Director of the Observatories of the Carnegie Institution of Washington in Pasadena, Calif. Freedman served as scientific leader for a team of 30 astronomers who carried out the Hubble Key Project to measure the current expansion rate of the universe. At the project’s start in the mid-1980s, the age and size of the universe ranged between 10 and 20 billion years. The project’s final results resolved this longstanding debate, determining the age of the universe as 13.7 billion years with an uncertainty of 10 percent. She served as co-leader of the Carnegie Supernova Project to study exploding stars to provide constraints on the nature of dark energy, a mysterious force that appears to be accelerating the expansion of the universe.

Currently, Freedman focuses on measuring both the current and past expansion rate of the universe, and on characterizing the nature of dark energy. She is leading a project to use the Spitzer Space Telescope to measure the expansion rate to an accuracy of three percent.

Freedman is an elected member of the National Academy of Sciences and of the American Philosophical Society. She also is an elected fellow of the American Academy of Arts and Sciences and of the American Physical Society. Additional honors include the American Physical Society’s Magellanic Prize, as well as the Gruber Cosmology Prize.

Cinema Slapdown Round 53: Gravity
September 19, 2014 | 7:00 PM | Film Row Cinema 1104 S. Wabash 8th Floor Chicago, IL 60605

Is Gravity a realistic view of the hazards of intergalactic travel, or just a reboot of old movie serials with weightlessness thrown in? Is it an examination of solitude and the human need to connect with others, or a soporific woman's weepie about the pains of unfulfilled motherhood? Gravitas or grasping for meaning?

C2ST will join Columbia College Chicago Cinema Art + Science for the first bout in a new season of Cinema Slapdown, as they take on Alfonso Cuarón's Oscar winning excursion to the edge of action movie archetypes. Featuring Cinema Art + Science Associate Professor and Slapdown Superstar Julian ("a spirited glimpse into the eternity of space") Grant versus University of Chicago Cosmologist and Dean of Physical Sciences Edward "Rocky" ("a dispiriting gaze at the edge of clichés") Kolb. Referee'd by Associate Professor and Talk Cinema host Ron Falzone.

Everything you see around you -- the chair you are sitting on, the grass beneath your feet, and the air you breathe, has a common feature. These objects emit and absorb light. This feature enables us to see, hear, touch, taste and smell the world around us. However, astronomers have discovered over the last 40 years that most of the 'stuff" in the universe does not actually interact with light! An astounding 95% of the universe's matter and energy takes an invisible form that cannot be explained by any of the currently known particles. Now, the hunt is on to uncover the nature of these novel substances, aptly named "dark matter" and "dark energy".

In these lectures, I will describe the cutting edge research which aims to understand the nature of dark matter and dark energy. This exciting field spans from observatories placed deep under the ice at the South Pole, to particle detectors on board the International Space Station, to simulations running on some of the world's largest supercomputers. Revealing the dark side of the universe will reshape our understanding of both the history and future of the universe, as well as our place within it.

Broader Horizons: Ali Vanderveld, Data Scientist at Groupon
November 18, 2014 | 4:00 PM | LASR conference room
Ali Vanderveld received her PhD in Physics from Cornell University in 2007, focusing on theoretical cosmology. After two postdocs, first at Caltech and then at KICP, she fell in love with Chicago and wanted to try something new. As such in 2013 she obtained a data scientist position at Groupon, where she now uses the same skills and tools that she once used to study the Universe to study the world of ecommerce. Her work involves answering complex questions with massive heaps of historical data, along with using machine learning techniques to optimize the business. She will discuss the pros and cons of this career change, the day-to-day life of a data scientist in tech, and how one might prepare to make such a transition.
