Event Date Summary
Massive and Partially Massless Gravity and Higher spins – Kurt Hinterbichler Tue. February 2nd, 2016
11:30 am-12:30 pm

On de Sitter space, there exists a special value for the mass of a graviton for which the linear theory propagates 4 rather than 5 degrees of freedom, known as a partially massless graviton. …Read more.

Cosmology from the Megaparsec to the Micron – Amol Upadhye Fri. February 5th, 2016
12:30 pm-1:30 pm

Two major challenges for cosmology over the next decade are to characterize the dark energy responsible for the cosmic acceleration and to weigh the neutrinos, the only Standard Model particles whose masses are not yet known. …Read more.

New Paradigm for Physics Beyond the Standard Model – Pavel Fileviez Perez Tue. February 9th, 2016
11:30 am-12:30 pm

The great desert hypothesis in particle physics defines the relation between the electroweak scale and the high scale where an unified theory could describes physics. In this talk we review the desert hypothesis and discuss the main experimental constraints from rare decays. …Read more.

Testing Early Universe Physics with Upcoming Observations – Emanuela Dimastrogiovanni Wed. February 10th, 2016
12:30 pm-1:30 pm

Cosmology has seen tremendous progress thanks to precision measurements and is bound to greatly benefit from upcoming Large Scale Structure and Cosmic Microwave Background data. I will point out a number of interesting directions. …Read more.

Joining Forces Against the Dark Side of the Universe: The Cosmic Microwave Background and the Large Scale Structure – Shirley Ho Fri. March 4th, 2016
12:30 pm-1:30 pm

Despite tremendous recent progress, gaps remain in our knowledge of our understanding of the Universe. For example, we have yet pinned down the properties of dark energy, nor have we confirmed Einstein’s theory of Gravity at the largest scales. …Read more.

New Probes of Large-scale CMB Anomalies – Simone Aiola Tue. March 15th, 2016
11:30 am-12:30 pm

Inflation prescribes a homogenous and isotropic universe on large scales, and it generates density fluctuations which are expected to be spatially correlated over the whole Hubble volume. Such fundamental predictions have been tested with current Cosmic Microwave Background (CMB) data and found to be in tension with our — remarkably simple — ΛCDM model. …Read more.

Calibration of the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) Detectors – Madeline Wade Tue. March 22nd, 2016
11:30 am-12:30 pm

Calibration is the critical link between the LIGO detectors and searches for gravitational-wave signals in LIGO data. The LIGO calibration effort involves constructing the external strain incident on each LIGO detector from the digitized readout of the LIGO photodetectors. …Read more.

New Approaches to Dark Matter – Justin Khoury Tue. March 29th, 2016
11:30 am-12:30 pm

In this talk I will discuss a novel theory of superfluid dark matter. The scenario matches the predictions of the LambdaCDM model on cosmological scales while simultaneously reproducing the MOdified Newtonian Dynamics (MOND) empirical success on galactic scales. …Read more.

Beyond Precision Cosmology – Licia Verde Tue. April 5th, 2016
11:30 am-12:30 pm

The avalanche of data over the past 10-20 years has propelled cosmology into the “precision era”. The next challenge cosmology has to meet is to enter the era of accuracy. Because of the intrinsic nature of studying the Cosmos and the sheer amount of data available and coming, the only way to meet these challenges is by developing suitable and specific statistical techniques. …Read more.

New Directions in Bouncing Cosmologies – Anna M. Ijjas Tue. April 19th, 2016
11:30 am-12:30 pm

In this talk, I will discuss novel ideas to smooth and flatten the universe and generate nearly scale-invariant perturbations during a contracting phase that precedes a cosmological bounce. I will also present some recent work on the possibility of having well-behaved non-singular bounces. …Read more.

Do We Understand the Universe? – Raul Jimenez Tue. April 26th, 2016
11:30 am-12:30 pm

Observations of the cosmos provide a valuable tool to study the fundamental laws of nature. The future generation of astronomical surveys will provide data for a sizeable fraction of the observable sky. …Read more.

Excursion Sets, Peaks and Other Creatures: Improved Analytical Models of LSS – Marcello Musso Tue. May 3rd, 2016
11:30 am-12:30 pm

I will present recent developments in analytical methods to predict abundance, clustering, velocities and bias of Dark Matter halos. In the standard analytical approach, halos are identified either with sufficiently high peaks of the initial matter density field, or with the largest spheres enclosing a sufficiently high density. …Read more.
