GWEOS-2019 Pisa Workshop

25 Feb 2019, 08:00 → 26 Feb 2019, 18:00 Europe/Rome

Room N. 131 (Physics Department - Pisa University and INFN - Sezione di Pisa)

Ignazio Bombaci (University of Pisa and INFN Pisa), Giancarlo Cella (INFN Pisa and Virgo Collaboration), Cristiano Palomba (INFN ROMA1 and Virgo Collaboration)

The idea of the workshop is to put together physicists with competences in gravitational waves, nuclear physics and neutron star physics to create a bridge between these communities and to foster future collaborations.

A large amount of time is allocated for discussions, and the style of the communications should be open to dialogue. Here is a list of issues we aim to discuss:

• What kind of constraints on the equation of state (EOS) of matter at very high densities are allowed by the present and future GW detector sensitivities?

• What are the most up to date theoretical models for the EOS?

• Can neutron stars sustain long-lived large quadrupolar deformations?

• What is the current state of the art for numerical simulations?

• What are the more urgent theoretical challenges?

• What are the most relevant analysis limitations?

• How can we bring together GW and EM constraints?

• What do we expect to gain with third-generation GW observatories for fundamental physics of matter at extreme densities?

Foreseen talks are on invitation only, but registration is open to everyone interested (within a numerical limit). Registrants are welcome to participate to the discussions.

We are happy to acknowledge the support of:

• European Gravitational Observatory
• Istituto Nazionale di Fisica Nucleare
• Università degli studi di Pisa (Dipartimento di Fisica)

11 TEOBResumS: efficient and accurate analytical waveform model for spin-aligned coalescing binaries

will review the status of TEOBResumS, a freely available analytical waveform model, based on the effective
one body approach (improved by numerical relativity simulations), to generate highly-accurate (and computationally
inexpensive) time-domain (multipolar) waveforms for spin-aligned coalescing binaries. The model includes tidal
interaction as well as EOS-dependent self-spin couplings (at high order) and is viable for both coalescing black holes
through merger and ringdown or neutron stars (as well as mixed binaries) up to merger. Implications for data-analysis
and in particularly its use on GW170817 are explicitly discussed.
