Description

A stochastic gravitational-wave background is the persistent signal that comes from overlapping, unresolved independent sources. These signals are individually undetectable, but detectable as a collectivity via their common influence on multiple detectors - the musical companion to the binary black hole or binary neutron star soloist. This hum will provide insights into our universe’s early history, allowing us to listen to the first-ever song of the universe in multiple frequency bands. The Gravitational Wave Orchestra 2022 will act as the ideal backdrop to listen to the various aspects of the gravitational-wave symphony.

During this two-day workshop (in-person), we will hear from:

  • Joseph Romano (TTU, Lubbock)

  • Irina Dvorkin (IAP, Paris)

  • Vuk Mandic (UMN, Minnesota)

  • Chiara Caprini (U. Geneva & CERN)

  • Stephen Taylor (Vanderbilt U., Nashville)

  • Giulia Cusin (U. Geneva & IAP, Paris)

  • Sanjit Mitra (IUCAA, Pune)

  • Tania Regimbau (LAPP, Annecy)

  • Carlo Contaldi (Imperial College, London)

  • Sébastien Clesse (ULB, Brussels)

  • Josquin Errard (APC, Paris)

  • Boris Goncharov (GSSI, L’Aquila) 

  • Guillaume Boileau (U. Antwerpen)

  • Aditya Parthasarathy (MPIfR, Bonn)

  • Alex Jenkins (UCL, London)

  • Kamiel Janssens (U. Antwerpen & ARTEMIS, Nice)

on a broad range of topics including:

  • Review on stochastic gravitational-wave backgrounds.
  • Theoretical development in stochastic gravitational-wave background modelling.
  • Most updated results from the LIGO-Virgo-KAGRA collaboration and Pulsar Timing Arrays.
  • Future probes and strategies using: Einstein Telescope, Cosmic Explorer, and LISA.

Along with this, we will have a poster session and lightning talks. You are strongly encouraged to submit a poster abstract on stochastic gravitational-wave background-related research. Details can be found on the abstract submission page.

Registration and abstract submission deadline: August 05, 2022
Registration and abstract submission deadline (extended): August 12, 2022

Registration and abstract submission: Closed.
