The seminar series De Madrid al Cosmos ("From Madrid to the Cosmos") fosters the dissemination of research in theoretical cosmology and related topics. The seminars are accesible to a non-specialist public with some knowledge of fundamental physics.

The seminars are organized jointly by the Effective Theories in Modern Physics Group of the Complutense University of Madrid and the Gravitation and Cosmology Group of the Institute for the Structure of Matter (IEM-CSIC).

Avances recientes en gravedad cuántica de lazos con simetría esférica

SpeakerJorge Pullin
Affiliation: Louisiana State University
Abstract: Detallaremos recientes resultados en gravedad cuántica de lazos con simetría esférica, incluyendo la solución exacta de las ecuaciones cuánticas de Einstein, el tratamiento de campos cuánticos que viven en la misma, el efecto Casimir, la radiación de Hawking y la evolución de cáscaras nulas como modelo de colapso, así como  las implicaciones para la paradoja de la información.
Date and time: 11 July 2018, 15:00 h.
Venue: CSIC, CFMAC, conference room (121 Serrano St.)

 

No LIGO MACHO: the Dark Universe in the Gravitational Wave Era

SpeakerMiguel Zumalacárregui
Affiliation: Louisiana State University
Abstract: Evidence shows that we live in a universe where 95% of the matter and energy is of unknown nature. Right from the onset, Gravitational Wave (GW) astronomy is shaping our understanding of the dark universe in several ways: GW signals of black hole mergers have resurrected the idea of Dark Matter being made of primordial black holes, while multi-messenger GW astronomy has generated novel ways to test Dark Energy and the fundamental properties of gravity. I will discuss the impact of gravitational waves on the landscape of gravitational theories, and how the recent observation of a neutron star merger spectacularly rules out a large class of Dark Energy models in which the speed of GWs is variable, including some (otherwise viable) contenders to the cosmological constant. Then I will present how gravitational lensing of distant supernovae constrains the abundance of primordial black holes, which can not be the dominant form of Dark Matter.
Date and time: 12 July 2018, 15:00 h.
Venue: UCM, Faculty of Physical Sciences, Theoretical Physics I Dept., seminar room (3rd floor)
