Events During the Week of November 20th through November 26th, 2016
Monday, November 21st, 2016
- NPAC (Nuclear/Particle/Astro/Cosmo) Forum
- Recent highlights from the VERITAS gamma-ray observatory
- Time: 2:00 pm
- Place: 4274 Chamberlin Hall
- Speaker: Marcos Santander , Barnard College - Columbia University
- Abstract: The continuing study of the gamma-ray sky has revealed a large population of extreme astrophysical accelerators capable of emitting electromagnetic radiation up to the highest observable energies, in the TeV range. Above 100 GeV, gamma-ray observations can be performed from the ground using large optical telescopes sensitive to the Cherenkov radiation emitted by gamma-ray air showers. The VERITAS observatory, an array of four Cherenkov telescopes located in Southern Arizona, uses this technique to study Galactic and extragalactic sources, probe cosmological radiation fields, and search for evidence of dark matter, among other science projects. In this talk, I will summarize recent results from the VERITAS observatory and describe synergies with other observatories currently in operation. I will briefly describe the Cherenkov Telescope Array (CTA), the next-generation TeV gamma-ray instrument, that will provide an order-of magnitude improvement in sensitivity over current instruments such as VERITAS and the status of the US contribution to this project.

Tuesday, November 22nd, 2016
- Chaos & Complex Systems Seminar
- Asleep or awake? Local sleep in health and disease
- Time: 12:05 pm - 1:00 pm
- Place: 4274 Chamberlin (refreshments will be served)
- Speaker: Stephanie Jones, UW Department of Medicine and Public Health
- Abstract: The group of researchers at the Wisconsin Institute for Sleep and Consciousness at UW-Madison is arguably one of the best in the world, and some truly ground-breaking work on the function of sleep has been generated here. This talk will highlight much of this work and will focus, in particular, on the brain’s remarkable capacity for sleeping (and waking) at the same time, and the implications this has for brain health, development and disease.
- Host: Clint Sprott
- NPAC (Nuclear/Particle/Astro/Cosmo) Forum
- An overview of FBK Silicon Photomultipliers characterization
- Time: 2:30 pm
- Place: 5310 Chamberlin hall
- Speaker: Daniela Simone, INFN Bari
- Abstract: I will report a characterization of the NUV Silicon Photomultipliers (SiPMs) developed by Fondazione Bruno Kessler and tested at INFN in Bari (Italy). A dedicated setup has been built in order to measure crucial parameters such as gain, correlated noise and signal – to –noise ratio. The devices tested are SiPMs of different cell size and areas in single or matrix configuration. In particular, I will present last results concerning laboratory tests on the new NUV High Density SiPMs, which are characterised by an increased fill factor respect to the NUV devices.
- Host: Justin Vandenbroucke
- Theory Seminar (High Energy/Cosmology)
- Neutrino Masses: First Signal From SUSY!
- Time: 3:30 pm
- Place: 5280 Chamberlin
- Speaker: Seyda Ipek, Fermilab
- Abstract: We know neutrinos have mass, but we don't know how they get their masses. Many models augment the Standard Model with right-handed neutrinos, either Dirac or Majorana, to generate the neutrino masses. I will show that in R-symmetric supersymmetric models, the bino and its Dirac partner the singlino can play the role of right-handed neutrinos. In this mechanism the neutrino masses are generated in a very simple fashion. I will also discuss low and high energy constraints/signatures in this framework.
