The KICP will welcome 4 new Fellows in the Autumn of 2015
January 26, 2015
Camille Avestruz will join us as a joint KICP and Enrico Fermi Fellow after receiving her degree from Yale University. Camille's research uses hydrodynamic cosmological simulations to study clusters of galaxies. She is interested in using simulations to interpret observations and to model astrophysical processes that affect cluster-based cosmology.
Nicole Larsen will join the KICP as a Fellow after completing her PhD at Yale University. Her background is in dark matter direct detection. Specifically, her graduate work was on the Large Underground Xenon (LUX) experiment, where she worked extensively on detector hardware and on using LUX data to set limits on complex types of dark matter interactions. At the KICP, Nicole is interested in broadening her horizons by moving into CMB physics.
Ritoban Basu Thakur completed his PhD between University of Illinois Urbana Champaign and Fermilab Center for Particle Astrophysics. His thesis was on developing new ultra low threshold cryogenic detectors for dark matter searches (SuperCDMS / CDMSlite). At KICP he plans to work on the next generation CMB cameras (SPT-3G) and continue efforts in progressing low threshold dark matter detectors with CCDs (DAMIC).
Congratulations to Dr. Alan Zablocki!

"Over the last decade, cosmological observations have placed increasingly stringent upper bounds on the masses of neutrinos, while observations of neutrino oscillations imply a lower bound. Alan's thesis provides a detailed forecast of the constraints that the Dark Energy Survey (DES) will be able to place on neutrino mass in the next few years, accounting for uncertainties in dark energy and in the relative amplitude of galaxy clustering. He finds that DES has a good chance of shedding light on the pattern of neutrino masses (the mass hierarchy), an exciting possibility. His results will be of broad interest to cosmologists."

Nine Scientific Pioneers Receive the 2014 Kavli Prizes
May 29, 2014
Kavli Prize in Astrophysics
The Kavli Prize in Astrophysics is shared between Alan H. Guth, Massachusetts Institute of Technology, USA, Andrei D. Linde, Stanford University, USA, and Alexei A. Starobinsky, Landau Institute for Theoretical Physics, Russian Academy of Sciences, Russia. They receive the prize "for pioneering the theory of cosmic inflation". The theory of cosmic inflation, proposed and developed by the three prize winners, has revolutionized our thinking about the Universe.
According to this theory, very soon after our universe came into existence it underwent a short-lived phase of exponential expansion. During this brief period the universe expanded by a huge factor - hence the name inflation. The consequences of this episode were momentous for the evolution of the cosmos.The field of inflation theory now occupies thousands of theorists, and many variations of inflation are being actively debated.
Kavli Prize in Nanoscience
The Kavli Prize in Nanoscience is shared between Thomas W. Ebbesen, Universite Louis Pasteur, Universite de Strasbourg, France, Stefan W. Hell, Max Planck Institute for Biophysical Chemistry, Germany, and Sir John B. Pendry, Imperial College London, UK.
They receive the prize "for transformative contributions to the field of nano-optics that have broken long-held beliefs about the limitations of the resolution limits of optical microscopy and imaging".
With their respective work, they have challenged established beliefs about the resolution limits of optical imaging, showing that light can interact with nanostructures smaller than its wavelength.
Seeing at the 'nanoscale' was long considered to be limited in visible resolution by the finite wavelength of 'light', so that only objects larger than ~ 200 nanometers could be imaged. This is about 100 times smaller than the diameter of a human hair.
Each of this year's prize winners, through their different insights and routes, has independently advanced our ability to 'see' nanostructures using 'ordinary' light. This ability to see and image nanoscale objects is a critical prerequisite to further advances in the broader field of nanoscience.
Kavli Prize in Neuroscience
The Kavli Prize in Neuroscience is shared between Brenda Milner, Montreal Neurological Institute, McGill University, Canada, John O'Keefe, University College London, UK, and Marcus E. Raichle, Washington University in St.Louis School of Medicine, USA. They receive the prize "for the discovery of specialized brain networks for memory and cognition".
The recipients of the Kavli Prize in Neuroscience have all played major roles in advancing our understanding of memory and in the development of techniques to measure the brain. They have discovered that these functions are produced by specialized systems in the brain, which they analysed through a variety of research approaches. They have found the specific regions of the brain that are involved in memory, and how specialized nerve cells perform different roles.
The higher cognitive functions of our brains such as attention, memory, and planning are crucial to create our rich mental lives: memory is essential for humans, from the recognition of where we are, through learning new skills, to being able to recall events. In humans memory can be said to define who we are, and we know that loss of memory can have devastating effects on an individual's personality. Knowing how memory function should work in healthy people could open the door to understanding what has changed in patients with dementia and memory loss.
About the Kavli Prizes
The Kavli Prize is a partnership between The Norwegian Academy of Science and Letters, The Kavli Foundation (USA) and The Norwegian Ministry of Education and Research. The Kavli Prizes were initiated by and named after Fred Kavli (1927 - 2013), founder of The Kavli Foundation which is dedicated to advancing science for the benefit of humanity, promoting public understanding of scientific research, and supporting scientists and their work.
Kavli Prize recipients are chosen biennially by three prize committees comprised of distinguished international scientists recommended by the Chinese Academy of Sciences, the French Academy of Sciences, the Max Planck Society, the U.S. National Academy of Sciences and The Royal Society. After making their selection for award recipients, the recommendations of these prize committees are confirmed by The Norwegian Academy of Science and Letters.
The 2014 Kavli Prizes will be awarded in Oslo, Norway, on the 9th of September. His Majesty King Harald will present the prizes to the laureates. This year's ceremony will be hosted by Alan Alda and Haddy N'jie.
The ceremony is part of Kavli Prize Week - a week of special programs that celebrate extraordinary achievements in science, educate the public on important scientific advances, and bring together distinguished members of the international community to discuss key global issues in science and science policy.
For more detailed information on each of the prizes, the 2014 laureates and their work, and Kavli Prize ceremony and other events during the Kavli Prize Week in September.

Cosmic WOW: BICEP2 announces evidence for the gravity waves produced by inflation!
March 17, 2014
KICP Faculty member Abigail Vieregg and KICP Fellow Christopher Sheehy are part of the BICEP2 Team that today announced evidence for the discovery of the CMB B-mode signature of gravity waves produced during inflation. KICP Director Michael Turner said that if this result holds up, it will be the biggest event in cosmology since the discovery of CMB anisotropy or the accelerated expansion of the Universe. Inflation-produced gravity waves are called the smoking' gun of inflation - and for good reason. Their amplitude reveals the expansion rate during inflation and the scale of inflation (about 10^-38 sec and 10^16 GeV respectively for the BICEP2 detection) and confirms the third key prediction of inflation. The first two predictions of inflation - almost scale-invariant density perturbations and a flat Universe - are almost postdictions, as both had been put forth as features of any sensible cosmological model before inflation was postulated in the early 1980s. Because of the large number of highly sensitive CMB experiments that are taking or analyzing data (including SPT and Planck), the BICEP result will be checked very soon. Read more Michael Turner's comments.
"What an amazing discovery. The BICEP2 results are truly fantastic. They provide -- at very high confidence -- evidence for the inflationary origin of our universe, probing physics at the energy scales of grant unified theories and the first instants of the universe. While the signal is tiny -- they measured the polarization of the cosmic microwave background with a sensitivity of 30 millionths of the 3 K background -- it is actually stronger than most cosmologists thought it would be. This means that BICEP2 data along with KECK Array and SPTpol data and upcoming BICEP3 and SPT-3G data all from the same region of the sky, will allow us to not only confirm the BICEP2 results, but also to constrain the inflation model further. it is a fantastic day for cosmology and indeed for all of physics."
