7. Status of Neutrino Astronomy

Dr Carsten Rott (Sungkyunkwan U.)

12/10/2015, 09:15

The latest results from neutrino telescopes will be reviewed. The observation of high-energy astro-physical neutrinos by IceCube will be discussed and potential sources candidates evaluated. The talk will conclude with an overview of the discovery potential at the next generation of neutrino telescopes.

10. Baryon Acoustic Oscillations: A Robust and Precise Route to the Cosmological Distance Scale

Dr Daniel Eisenstein (Harvard U.)

12/10/2015, 10:00

The baryon acoustic oscillations now provide one of our most robust methods for measuring the cosmic distance scale. I will review the physical principles of the method and describe some recent developments in the practical methodology. I will then present recent BAO results and cosmological implications from the Baryon Oscillation Spectroscopic Survey, part of Sloan Digital Sky Survey III. ...

13. Status of CMB observations: Planck and beyond

Dr Martin Bucher (APC/U. of Paris)

12/10/2015, 11:05

I will review the current status of CMB observations focusing on the ESA Planck mission. I will also review the status of B modes searches, reviewing the current limits and the many experiments coming online or in the planning stage that promise either to make a first discovery or to substantially tighten current upper bounds.

14. Progress and Status of PandaX experiment in China Jinping Underground Lab

9. Cosmic Infrared Background

Dr Asantha Cooray (U.C. Irvine)

13/10/2015, 09:00

In this talk I will summarize applications and measurements related to the cosmic infrared background (CIB), its power spectrum and cross-correlations, among others.

8. Searching for dark matter with gamma rays

Dr Simona Murgia (U.C. Irvine)

13/10/2015, 09:45

Evidence for dark matter is overwhelming. From experimental data we can infer that dark matter constitutes most of the matter in the Universe and that it interacts very weakly, and at least gravitationally, with ordinary matter. However we do not know what it is. Several theoretical models have been proposed that predict the existence of Weakly Interacting Massive Particles (WIMPs) that are...

21. Neutrinos in cosmology

Dr Yvonne Wong (U. of New South Wales)

13/10/2015, 11:00

12. Cosmology with the HETDEX survey

Dr Donghui Jeong (Penn State U.)

13/10/2015, 11:45

HETDEX (Hobby-Eberly Telescope Dark Energy eXperiment) is a galaxy survey targeting Lyman-alpha emitters (LAEs) at high redshifts (1.9 < z < 3.5). Starting from late 2015, the survey will observe about a million LAEs over ~400 sq. degrees, which corresponds to ~10Gpc³ in volume. The main science goal of HETDEX is to measure the angular diameter distance and the Hubble expansion...

19. Theory for Neutrino Mixing

Dr Xiao-Gang He (Shanghai Jiao Tong Univ./National Taiwan Univ.)

15/10/2015, 09:00

Tremendous progresses on neutrino mixing have been made both experimentally and theoretically. Recent data show that the mixing angles in the PMNS are not always small as their quark mixing counter part. In the standard parametrization for three neutrino mixing commonly used, the mixing angle θ₂₃ is close to π/4, θ₁₂ is also large, θ₁₃ is...

75. Towards gauge theory for EW scale DM

Dr Pyungwon Ko (KIAS)

15/10/2015, 09:45

I present gauge models for EW scale DM, and discuss the role of DM, dark gauge bosons and dark Higgs in this class of models in the context of particle physics, DM phenomenology and cosmology, including Higgs signal strength, collider searches of DM, galactic center gamma ray excess, dark radiation and Higgs inflation.

20. Axions: Diversity beats Simplicity

Dr Hans Peter Nilles (Bonn U.)

15/10/2015, 11:00

While axions have been initially proposed as a solution of the strong CP-problem, they might also find useful applications in cosmology: as candidates for cold dark matter, dark energy (quintessence) and inflation. The ultraviolet completion within the framework of string theory provides a plethora of axions and motivates the consideration of mult-axion systems as a solution to some of the...

16. Inflation in String Theory

Dr Gary Shiu (U. of Wisconsin)

15/10/2015, 11:45

15. From CMB Observations to Inflation

Dr Raphael Flauger (Univ. of Texas)

16/10/2015, 09:00

I will discuss the implications of the Planck full mission data as well as the BICEP/KeckArray data for early universe cosmology and will outline what we may hope to learn from upcoming experiments.

17. Quantum Primordial Standard Clocks

Dr Yi Wang (HKUST)

16/10/2015, 09:45

In this paper, we point out and study a generic type of signals existing in the primordial universe models, which can be used to model-independently distinguish the inflation scenario from alternatives. These signals are generated by massive fields that function as standard clocks. The role of massive fields as standard clocks has been realized in previous works. Although the existence of such...

18. Gravitational waves from the early Universe

Dr Jun'ichi Yokoyama (RESCEU)

16/10/2015, 11:00

The gravitational wave is a useful probe of the early Universe which directly carries information of the epochs all the way up to the inflationary era. There are a number of production mechanisms of gravitational waves in the early Universe such as: (i) quantum tensor perturbation generated during inflation, (ii) gravitational waves generated by second-order perturbation of density...
