Gravitational waves from neutron star collisions carry key information about matter at extreme densities. Advanced LIGO and Virgo can, for example, constrain the properties of zero-temperature neutron star's equation of state by estimating the tidal polarizability coefficients that parametrize the neutron stars' tidal interactions in the inspiral-merger phase. Third generation detectors might...

7. Modelling the ejecta and electromagnetic counterparts from binary neutron star mergers

The first detection of GWs from a binary neutron star merger (GW170817) marked the beginning of the multimessenger astronomy era. A few hours after the GW detection, the observation of an associated electromagnetic counterpart compatible with a kilonova/macronova emission remarkably confirmed our basic picture concerning the ejection of matter and the nucleosynthesis occurring in such a kind...

The unprecedented observation of a binary neutron star coalescence by the Advanced Virgo and Advanced LIGO gravitational-wave detectors offers the opportunity to cast new light on neutron stars and matter under the most extreme conditions. Furthemore, for the first time we were able to observe the engine that powers events such as gamma ray bursts. After such a merger, a compact remnant is...

8. Recent results and future challenges for Continuous waves and Stochastic background searches with a network of gravitational wave detectors

Invited

Continuous gravitational waves and stochastic background searches are among the main targets of present and future gravitational wave searches. These sources have not been detected so far, anyhow important progresses have been made in the development of search procedures and significant constraints on source characteristics have, in some cases, been put. I will highlight the most recent...

15. LISA as a probe for particle physics

Germano Nardini (University of Bern)

02/03/2018, 11:20

In this talk we review why the measurement of the stochastic gravitational wave background can shed light on the particle content of the Universe. We moreover sketch some popular particle physics theories for which LISA can prove the existence of new physics before colliders.

3. GW170817 Falsifies Dark Matter Emulators

Prof. Emre Kahya (Istanbul Technical University)

02/03/2018, 11:40

The gravitational wave (GW) signal (GW170817) from the coalescence of binary neutron stars was simultaneously seen throughout the electromagnetic (EM) spectrum from radio waves to gamma-rays. We point out that this simultaneous detection rules out a class of modified gravity theories, and provides another indirect evidence for the existence dark matter.

2. Electromagnetic counterpart searching for gravitational wave

During the second science run(O2) of the Laser Interferometer gravitational-wave Observatory (LIGO) and Virgo Interferometer, a gravitational-wave signal consistent with a binary neutron star coalescence(BNS) was detected on 2017 August 17th (GW170817), quickly followed by a coincident short gamma-ray burst(GRB170817a) trigger by the Fermi satellite. 10 hours later, 6 groups independently...
