New People at KICP

Please join us in welcoming the two new Postdocs who joined the KICP this Summer.

Dragan Huterer is a theoretical cosmologist who comes to Chicago from Case Western Reserve University. His interests include dark energy and using large-scale structure surveys and weak and strong gravitational lensing as tools of precision cosmology.

Yong-Seon Song is also a theoretical cosmologist who recently graduated from the University of California, Davis. His main interests lie in constructing and testing models for the dark energy and the origin of structure in the universe.

Science News

Resolving the "missing satellites problem"

Professor Andrey Kravtsov’s research was highlighted on The University of Chicago’s web site.

In addition to the UC News Office, these results were featured in Scientific American, Discover, Astronomy Now, European Science Now, Science Daily and Mexican Astrociencia magazines.

Resolving the "missing satellites problem"

A generic prediction of the standard galaxy formation paradigm is that dark matter halos are "lumpy", filled with hundreds of dense, gravitationally bound clumps of dark matter. The abundance of these clumps is much larger than the typical number of dwarf satellites around galactic halos --- the discrepancy often called "the missing satellites problem". Kravtsov and his collaborators proposed a solution to the missing satellites problem based on the observations that dwarf galaxy size objects in numerical simulations often undergo dramatic mass evolution. In general, astrophysicists believe that formation of very small dwarf galaxies should be suppressed. This is because gas required for continued formation of stars can be heated and expelled by the first generation of exploding supernovae stars. In addition, ultraviolet radiation from galaxies and quasars that began to fill the universe approximately 12 billion years ago heats the intergalactic gas, shutting down the supply of fresh gas to dwarf galaxies. Kravtsov found that some of the dwarf galaxies that are small today have been more massive in the past and could gravitationally collect the gas they need to form stars and become a galaxy. The result puts the cold dark matter scenario on more solid ground.

Anatomy of a big stereo hybrid event from the Auger Observatory

The Chicago AUGER Project is headed by Professor James Cronin

The Pierre Auger Observatory is now operating with more than 420 tanks and two complete fluorescence telescopes. On average 2.5 events with energy 1019 eV are recorded each day. Recently a beautiful event with energy ~ 5x1019 eV was observed by the surface detector and both fluorescence telescopes. The view of the event on the surface is shown in Figure 1.

The axis of the shower was aimed at Coihueco and the light received was totally dominated by Cherenkov light. The observed light profile at Coihueco is shown in Figure 2. The light observed is so dominated by direct Cherenkov light that the profile, while useful for geometric reconstruction is not suitable for energy determination.

The light received at Los Leones is nearly pure and after a small correction for scattered Cherenkov light and atmospheric absorption the number of charged particles can be determined using the fluorescence efficiency determined in laboratory experiments. Integration of this curve using a dE/dx of 2.2 MeV/gm/cm2 gives an electromagnetic energy of 4.9 x 1019 eV. Correcting for the energy carried by muons and neutrinos the total energy is estimated to be 5.4 x 1019 eV. The number of charged particles as a function of atmospheric depth is shown in Figure 3.

Chicago CAPMAP

The Chicago CAPMAP group is headed by Professor Bruce Winstein

The Chicago Capmap group, focusing on measuring the polarization of the CMB at very fine angular scales, is working on a number of fronts. KICP Fellow Dorothea Samtleben is leading the analysis effort at Chicago and is drafting a paper on the results of the experiment from its first year of observations. She will represent the group, speaking at the upcoming Cosmo04 conference in Toronto next month. Next season holds good promise and the group is getting two dewars, each with 4 detectors, ready for this coming season which should start in November. Princeton is doing the same and the combined sensitivity will likely be an order of magnitude better than for CAPMAP's first season. With Simon Swordy as associate director, Bruce has a little more time for research; he's helping get a proposal called QUIET, which uses a very large number of compact coherent detectors (developed at JPL) for polarization detection, ready for consideration by the National Science Foundation. QUIET is a new collaboration which includes the CAPMAP and CBI groups (Chicago, Princeton, Miami, JPL; Caltech), and former CfCP Associate Amber Miller from Columbia, as well as others.

KICP Visitors

Spring quarter was busy with a few short-term visitors: Robert Bonadurer (Minnesota Planetarium Society) April 14 - 15; Daniel Chung (University of Wisconsin) April 16; George Chapline (Lawrence Livermore National Laboratory) May 27 – 29; Joel Primack (University of California, Santa Cruz) June 3 – 5.

Over the next couple of months we will have several long-term visitors:

  • Professor Paolo Privitera (Universita di Roma Tor Vengata) will arrive August 15 and will visit for one year. Professor Privitera is one of the leaders of the Florescence detector efforts at the Pierre Auger Observatory and he will spend his time here working with the Chicago Auger group led by Professor James Cronin. He will also bring his experiment to Argonne National Laboratory.

  • Professor Roman Scoccimarro (New York University) is visiting us for the period September 15 – December 15, 2004. His areas of research are theoretical cosmology, large scale structure of the universe, gravitational clustering and primordial fluctuations.

  • Professor Naoshi Sugiyama (National Astronomical Observatory in Japan) will be visiting for the period October 1 – 31, 2004. Professor Sugiyama is best known for his CMB theory work – most recently using WMAP to constrain alternate cosmologies and models for early reionization (decaying particles, isocurvature fluctuation, non-gaussianity).

  • Professor Daniel Akerib (Case Western Reserve University) is visiting for the period October 10 – November 20, 2004. While here he will collaborate with Professor Juan Collar and Postdoc Andrew Sonnenschein on background issues in dark matter experiments and also on bubble chambers and other approaches to dark matter detection.

  • Olivier Dore (Princeton University), will be visiting for the period October 14 – 31, 2004. Olivier is a member of the WMAP team and his visit is timely given the upcoming polarization release.

This Fall we also have several upcoming short-term visitors:

  • Avi Loeb (Harvard University), hosted by John Carlstrom will be visiting for the period September 2 – 4, 2004, and will give a special seminar titled "When Was the Universe Reionized?".

  • Martin White and Joanne Cohn (University of California, Berkeley) who are being hosted by Wayne Hu will be here for the period September 6 –10, 2004.

  • Raul Jimenez and Licia Verde (University of Pennsylvania) who are being hosted by Wayne Hu will be visiting for the period October 1 – 4, 2004.

  • Alan Watson (University of Leeds) is returning for two short visits, from October 3 – 9, 2004 and then again from October 12 – 16, 2004. Jim Cronin is his host.

We also have several other visitors here for only one or two days that will be giving either our Wednesday Colloquia or our Friday Lunch Seminar. Our upcoming seminar and colloquia speakers are:

  • Richard Ellis of Caltech, October 6th colloquia;
  • Beth Willman of New York University, October 15th seminar;
  • Uros Seljak of Princeton University, October 20th colloquia;

Conferences and Workshops

2004 Yerkes Summer Institute, August 7-13, 2004

Theme: "What Are Stars Made Of?" a.k.a. Spectroscopy

Between summer and the school year the Space Explorers joined members of the KICP at Yerkes Observatory in Williams Bay, WI for a week long investigation into spectroscopy structured around an organizing question, "What are stars made of?" After an introductory star party hosted by the Milwaukee Astronomical Society, the students cycled through three all-day laboratories.

  • "You Are the Spectrometer" employed a series of optical elements to project spectra of the sun, discharge tubes and other light sources on giant scales that the students could then measure and compare.

  • "Fingerprinting the Stars" dove directly into comparing stellar spectra, identifying elemental components and determining temperature ranges.

  • "What’s in the Mix" examined colored liquids and directly demonstrated how one uses spectroscopy to determine components of a mixture (e.g. similar to how one dissects stellar spectra for elemental components).

Nighttime laboratories included viewing astronomical spectra directly through a telescope, capturing and analyzing spectra with a CCD camera, and using flame tests to identify elements. The students worked an additional two days extending a day lab, describing the investigation to their peers and preparing a presentation on their work.

Members of the KICP and University community who helped make YSI 2004 a success included: Rich Kron, Monica Valluri, Randy Landsberg, Rick Kessler, Erin Sheldon, Kyle Cudworth, Carlos Cunha, Robert Friedman, Chris Greer, Sarah Hansen, Vivian Hoette, Thushara Perera, Andy Puckett, Douglas Rudd, Matthew Sharp, Eileen Sheu, Phil Wisecup, Brian Wilhite, and Charles Brass.

Extreme Astronomy @ the Planetarium, September 24 - 26, 2004

This three-day intensive short course will explore the most violent and mysterious realms of modern astronomy: astronomy of the highest energy phenomena. It will probe the science behind the violent worlds of black holes, neutron stars, active galactic nuclei, supernovae, high energy particles from space, x-ray & gamma-ray bursts as well as the experiments to observe these phenomenon. The instructors will be researchers at the scientific forefront who are trying to understand these incredibly powerful events. The course will provide participants with a firm foundation in modern high energy astronomy. It will also offer practical tools, such as short animations, that will help participants bring this world to a wider audience. Ultimately this KICP course aims to help bring the excitement of discovery into the planetarium and thereby to the public.
