40. Ring-laser and fundamental physics

GINGER (Gyroscopes IN General Relativity) is a proposal aiming at measuring the Lense-Thirring effect with an experiment based on Earth. It utilises an array of ring lasers, which are the most sensitive inertial sensors to measure the angular rotation rate of the Earth. This experiment is Earth based, it is well known that Lense Thirring tests are currently done with space experiment, but the...

41. Neutrino properties from Cosmology`

The presence of a cosmic background of relic neutrinos is a robust prediction of the standard cosmological model. A direct detection is extremely difficult and still lacking. Nevertheless cosmological observations are a powerful probe of neutrino properties, and cosmological bounds on neutrino masses and number are in agreement with both theoretical predictions and laboratory searches. In this...

42. To B or not to B: Primordial magnetic fields from Weyl anomaly

Dr Takeshi Kobayashi (ICTP)

26/10/2018, 10:30

For more than twenty years, it has been argued that the Weyl anomaly of quantum electrodynamics sources cosmological magnetic fields in the early universe. If true, this would be a natural way to produce the seed magnetic fields of our universe within the Standard Model. In this talk, I will examine this long-standing claim and show that there is actually no production of coherent magnetic...

43. Gravitational waves and Multi-messenger astronomy: the new exploration of the Universe

Barbara Patricelli

26/10/2018, 11:30

The era of Gravitational Wave (GW) Astronomy started in 2015, with the first observation of GWs from the merger of a binary black hole system. Two years later, the detection of GWs from a binary neutron star merger and of its electromagnetic counterpart marked the birth of multi-messenger astronomy, opening a new chapter in the study of the universe. This talk will give an overview of the...

44. Dark matter searches in the very-high-energy gamma-ray band: can deep learning help?

Daniel Nieto (Universidad Complutense de Madrid )

Ground-based gamma-ray telescopes based on the imaging atmospheric Cherenkov technique (IACTs) are one of our best tools to access the very-high-energy (few tens of GeV and above) gamma-ray sky. Consequently, these instruments have the capability to offer observations in this particular energy band that may hint at the answers of some of the most pressing questions in Cosmology, like that of...

45. Simple self-consistent prediction methods for the phase space of dark matter: from galactic dynamics to phenomenology

Thomas Lacroix (Institut d'Astrophysique de Paris (IAP))

26/10/2018, 12:40

In the context of dark matter (DM) searches, it is crucial to quantify and reduce theoretical uncertainties affecting predictions of observables that depend on the DM velocity distribution, including event rates in direct searches, velocity-dependent annihilation rates, and microlensing event rates for DM compact objects. The well-known Eddington inversion formalism for the self- consistent...
