SEMINAR: Searching for dark mediators

June 19 2015, 12:00pm -  Seminar room

Speaker: Felix Kalhofer (DESY Hamburg)

Abstract : I will discuss dark matter models, which in addition to a new stable particle introduce a new mediator with a mass comparable to or even below the dark matter mass.

SEMINAR: Ultra-light dark matter and pulsar timing observations

June 18 2015, 12:00pm - Seminar room

Speaker: Andrei Khmelnitsky (Ben Gurion U of Negev)

Abstract : An ultra-light free scalar field with mass in the range 10^{-23} - 10^{-22} eV is a viable dark mater candidate. It can address the overabundance of cold dark matter structures on sub-galactic scales.

First light for the PAU camera, designed to study the dark energy in the Universe.

  • The camera's innovative technology allows the use of a new technique to precisely measure the accelerating expansion of the Universe.
  • The camera has been designed and built in Spain and is installed as a visiting instrument on the William Herschel telescope at the Roque de los Muchachos Observatory in La Palma, Canary Islands.
  • IFAE, ICE-CSIC/IEEC y PIC in Barcelona, CIEMAT and IFT-UAM/CSIC in Madrid participate in the project.

SEMINAR: Thermo-electric transport properties in holography with momentum dissipation.

June 4 2015, 12:00pm - Seminar room

Speaker: Nicodemo Magnoli (Genova U)

Abstract : In the first part of this seminar we will provide an analytical derivation of the transport coefficients of the simplest momentum dissipating model in gauge/gravity where the lack of momentum conservation is realized by means of explicit graviton mass in the bulk. In the second part we will investigate the possibility of formulating Planckian bounds in different models featuring momentum dissipation. We will show that in a holographic dilaton model it is possible to formulate a bound on the sum of the charge and energy diffusion constants.

SEMINAR: Aspects of string phenomenology in particle physics and cosmology

June 5 2015, 12:00pm - Seminar room

Speaker: Ignatios Antoniadis (Ecole Polytechnique, Paris)

Abstract : I will discuss the problem of scale hierarchies in string phenomenology and propose ways to address it.
