CCAPP Symposium 2011
Unraveling the Nature of the Universe with Current and Future Datasets

The Second Annual Symposium of The Ohio State University's
Center for Cosmology and Astro-Particle Physics (Columbus, OH USA)
Monday April 4 through Wednesday April 6, 2011

  • The CCAPP Symposium will take place over three consecutive days. In the morning and early afternoon of the first days keynote speakers will deliver overview talks. In the late afternoon the workshops will start in parallel sessions. Workshops continue on the second day and the morning of the third day.

Constraining Dark Energy and GR with Large Scale Structure Surveys

Combining multiple probes of large scale structure (BAO, galaxy clustering, galaxy-galaxy lensing, cosmic shear, ISW) is essential to place tight constraints on cosmological parameters, in particular when seeking information on dark energy scenarios and modifications to General Relativity. Present and near future wide-field imaging and spectroscopic surveys (e.g., CFHTLS, RCS, SDSS I and II, BOSS, DES) provide high-precision measurements of large scale structure, and combining these data sets and jointly analyzing the different LSS probes is a major task for cosmologists. The goal of this workshop is to develop strategies, methods, and specific projects to address this task.

Prospects for Interdisciplinary Science Onboard the International Space Station

With a size comparable to that of a football stadium in low Earth orbit, the International Space Station (ISS) is the most unique laboratory ever constructed. The ISS was commissioned as a National Laboratory since its completion in 2010 and will continue in that capacity until at least 2020. This workshop will explore the discovery potential afforded by the scientific synergy of in situ ISS experiments, including the "Monitor of All-sky X-ray Image" (MAXI) and "Alpha Magnetic Spectrometer" (AMS-02), with orbiting satellites, such as Swift and Fermi, as well as ground-based detectors, like IceCube. An emphasis will be placed upon investigating the viability of interdisciplinary research regarding quantifying the bio-molecular effects of transient astrophysical radiation from high energy photons and cosmic rays. The goals of the workshop include: (i) forging an interdisciplinary research team (IRT), (ii) assessing prospective science drivers, (iii) outlining action items and timescales towards proof of concept studies and (iv) identifying funding opportunities for future experiments aboard the ISS.

Supernovae Physics Potential of Current and Next Generation Neutrino Detectors

Supernova neutrinos are vitally important as they dominate the supernova energetics, and provide a window on the inner workings of core collapses. The observation of neutrinos from SN1987A has shown how indispensable this data is. We will review and explore new capabilities of operating neutrino detectors (such as SuperK and IceCube) and the data they produce. We will further discuss the potential of next generation neutrino detectors (Water-cherenkov, Liquid Argon, ...). We plan to summarize results of the workshop in a white paper.

Fermi and Ground Based Gamma-Ray Observations

In the last decade remarkable progress has been made in understanding high-energy phenomena in our Universe. The recently launched Fermi satellite has detected more than 1000 gamma-ray sources at GeV energies, which has led to important insights into the physics of violent astrophysical objects such as gamma-ray bursts and active galaxies with powerful cosmic jets. Fermi gamma-ray data has also yielded new constraints the properties of dark matter and on Lorentz invariance. On the other hand, ground-based gamma-ray telescopes, such as HESS, MAGIC, VERITAS, and Milagro, have discovered more than 100 sources at TeV energies, some of which have also been detected by Fermi. Despite these achievements several mysteries remain, including the origin of cosmic rays, the mechanisms of particle acceleration, and the fundamental nature of dark matter. This workshop aims to bring together theorists and experimentalists to discuss ways in which we can address these open questions using current and future ground-based gamma-ray detectors (CTA, HAWC) as well as Fermi. Major themes of the workshop will include new approaches to using the wealth of experimental gamma-ray data currently available, as well as ways to enhance the science returns of next-generation observatories.
