Dark Matter - Laura Baudis
We have strong evidence that about 83% of matter in our Universe is dark, revealing its presence only by its gravitational attraction. If the dark matter is made up of Weakly Interacting Massive Particles (WIMPs), it can be directly detected via elastic scattering from nuclei in ultra-low background, deep underground detectors. WIMPs arise naturally in many beyond-Standard-Model theories, a...

Non-Accelerator Neutrinos - John Learned??
I will begin with a summary of what we know about neutrinos, much of it
learned in non-accelerator particle physics experiments employing the
cosmic rays, the sun, radioactive sources and nuclear reactors. I will
also tally the open questions about neutrinos, curiosities associated
with neutrinos, and summarize efforts attempting to probe these (some to
be covered the subsequent...

Accelerator Neutrinos - Mike Shaevitz
It is now well established that neutrinos have mass and that there is mixing among the different neutrino types. This has led to many questions with respect to the properties of neutrinos, including why are the masses so small, are there more than three types such as additional sterile neutrino types, are there CP violations associated with neutrino oscillations, and are the neutrinos Dirac...

Neutrino Telescopes - A Journey - Christian Spiering
One can write the history of large neutrino telescopes as a story of leaking glass spheres, of light-scattering bubbles in ice, of the impact of the Cold War and of breaking empires, of failures and of over-optimistic assumptions. It was all of that. But more importantly, it was and is a great journey, made possible through stamina, eventual technological breakthroughs, great innovations,...

Mediterranean Neutrino Telescopes - Paschal Coyle
Most of the information that we have about the Universe has been conveyed by photons originating in electromagnetic processes. Neutrino telescopes offer the possibility to see the Universe with new "eyes," allowing the study of the most powerful cosmic accelerators via high-energy neutrinos generated in hadronic processes.
In the Mediterranean Sea, a number of efforts (ANTARES, NESTOR and...

Sources of High-Energy Neutrinos - Eli Waxman
The completed IceCube detector achieves the minimum sensitivity required for the detection of high energy extra-Galactic sources of neutrinos. I will discuss the prospects for detecting such sources, and the outstanding astrophysics and physics open questions that may be resolved by their detection. These open questions include the origin of ultrahigh energy cosmic, the underlying physics of...

IceCube - Olga Botner
The completion of the IceCube neutrino observatory represents a milestone for neutrino astronomy. A cubic kilometer of the Antarctic glacier has been transformed into the world's largest particle detector, aiming to explore and chart the sites of the most violent processes in the Universe. Some of these sources are out of reach for conventional astronomy, since the Universe is opaque to...

Astronomy / Cosmology - Neta Bahcall
Where is the Dark Matter located? How is it distributed on large scales? I will discuss recent observations using the Sloan Digital Sky Survey that utilize gravitational lensing to trace the mass distribution around galaxies and clusters of galaxies to the largest scales yet observed. We compare the mass distribution with the observed distribution of light and show that, while the mass...

Cosmology - John Carlstrom
The last decade has been a remarkable time for cosmology. We now have an testable model for the origin and evolution of the universe from its first instants to the present day. The model contains some remarkable components about which we know very little. Baryonic matter accounts for only a few percent of the make-up of the universe, dark matter accounts for roughly a quarter, and the dominant...

Gamma Rays from Space - Steve Ritz
The Fermi Gamma-Ray Space Telescope, formerly called GLAST, measures the cosmic gamma-ray flux in the energy range from 20 MeV to >300 GeV, with supporting measurements for gamma-ray bursts from 8 keV to 30 MeV. In addition, to breakthrough capabilities in energy coverage and localization, the very large field of view enables observations of 20% of the sky at any instant, and the entire sky...

TeV Gamma Rays - Eckart Lorenz
Gamma rays, like neutrinos, are "messengers" of distant, high-energy cosmic events, and are thus indispensible tools to help understand quite a few fundamental questions in our Universe. The field of gamma-ray astronomy is a section of high-energy particle astrophysics research. The window of TeV gamma-ray astronomy was only opened in 1989, with the discovery of the first TeV gamma-ray...
