1st Trieste meeting on the physics of gravitational waves, June 5-9 2023 at SISSA

[Mon-Tue] Gravitational Universe: Challenges and Opportunities (mid-term meeting) - June 5-6, 2023
This meeting will bring together researchers from Italy, France and Portugal to discuss the state of the art in the theoretical modelling of gravitational wave sources and in the development of data-analysis algorithms, with the aim of probing fundamental physics with gravitational waves.

[Wed-Fri] Environmental effects on binary black holes - June 7-9, 2023
The observation of gravitational waves from binary black holes and neutron stars by the LIGO-Virgo scientific collaboration heralds a new era in astrophysics, in which gravitational radiation will probe the universe in a new and complementary way to traditional telescopes. With several new detectors coming online soon, such as LISA, ET and Cosmic Explorer, these detections are just the beginning of an exciting scientific journey that will unravel the nature of the most mysterious objects of our Universe, black holes.

Connecting the dots - Toward inspiral-merger-ringdown gravitational waveforms beyond general relativity, June 14 – 16, 2023 at AEI Potsdam

The rapidly growing field of gravitational wave (GW) astronomy finally allows us to test general relativity (GR) in the dynamical, strong-field regime of a coalescing compact binary system. The detection and parameter estimation of these events crucially relies on providing accurate waveform templates to the LIGO-Virgo-KAGRA Collaboration, or to its successors in the next decade (such as the Einstein Telescope, the Cosmic Explorer and LISA). Yet, libraries of such waveform templates only exist in GR to this day.

26th Capra Meeting 3-7-July 2023 at The Niels Bohr Institute, Copenhagen

The 26th Capra Meeting will be hosted at The Niels Bohr Institute, Copenhagen from the 3rd - 7th of July 2023 ~ Registration is now Open. The Capra meeting is an annual workshop on the topic of radiation reaction in general relativity. The primary focus of these workshops is the development of the gravitational self-force approach to model extreme mass ratio inspirals and further our understanding of the two-body problem in general relativity.

Workshop "Infinity on a Gridshell", Copenhagen, Denmark, July 10-13 2023

The workshop "Infinity on a Gridshell" will take place from July 10 to July 13, 2023, at the Niels Bohr Institute, University of Copenhagen. The workshop will focus on the progress made in hyperboloidal methods, which have emerged as a crucial tool in black-hole perturbation theory and other diverse applications.

The workshop aims to bring together leading experts to review and summarize the current state-of-the-art of hyperboloidal methods in a wide range of applications, including the computation of wave equations, quasi-normal modes, effective-one-body formalism, and self-force. The focus will be on exploring ideas to solve the full Einstein equations for astrophysically relevant scenarios.

Multi-messenger Continuous Gravitational Waves, July 11 – 13, 2023, Amsterdam, NL

The first aim of this workshop is to bring together people inside and outside the LIGO/Virgo/KAGRA collaborations working on anything related to continuous gravitational waves, and to facilitate connections with astronomers that provide the necessary electromagnetic observations that enable us to search for continuous waves. The second aim of this workshop is to create a tutorials about how continuous-wave data analysis is done that will be accessible to anyone interested in getting involved in searches for continuous waves, as well as to broaden the understanding even amongst continuous-wave scientists about how these searches actually work.

15th Edoardo Amaldi Conference on Gravitational Waves, July 17-21, 2023

Amaldi Conferences, held biannually under the auspices of the Gravitational Wave International Committee, are the premier forum for gravitational waves. Amaldi15 will be hosted by the North-American Nanohertz Observatory for Gravitational Waves, and it will address the full spectrum of gravitational-wave science, including current and future detectors, data analysis, source modeling and populations, multi-messenger astronomy, and more. The theme for Amaldi15 will be “The broad reach of gravitational wave science.”

The meeting will be free, and all talks will be live-streamed and recorded, during three daily sessions spread over a 24-hour period. Registration and abstract submission will open on Monday, April 17 at amaldi15.org, and abstracts will be accepted through Monday, May 29. All further information, including the program of plenary talks and parallel sessions, will be continuously updated on the

Data analysis challenges for stochastic gravitational wave backgrounds 19-21 July 2023 at CERN

Seven years after the first discovery of a transient gravitational wave (GW) event by the LIGO/Virgo collaboration, a next milestone will be the discovery of a stochastic gravitational wave background (SGWB). Such a SGWB will contain unresolved astrophysical GW sources and will also provide a unique window to potential cosmological sources in the very early universe. However, a large number of challenges remain, including the discrimination of signal and noise, the discrimination between different contributions to the SGWB, and in general the challenge to maximize the science output from the upcoming experimental data.

Understanding cosmological observations, July 23 - August 5, 2023, Benasque, Spain

A new wave of data is arriving from large-scale structure observations and high-sensitivity CMB polarization measurements. This workshop will focus on the data and theoretical modelling required to robustly understand the new observations as non-linear and foreground physics becomes increasingly important, and on the range of theoretical models that could explain the data and be empirically tested in the next decade.

Gravitational Waves meet Amplitudes in the Southern Hemisphere, August 14 – September 1, 2023, ICTP-SAIFR, São Paulo

The central theme of the program will be the application of particle physics methods to the calculation of processes relevant to gravitational-wave phenomenology. We intend to bring together both experts and younger theorists from three distinct communities: Classical General Relativity, including both analytic and numerical approaches; Effective Field Theories; and Scattering Amplitudes. We also want to bring theorists into contact with observers and analysis specialists from LIGO-Virgo-KAGRA.

Asymmetric Binaries meet Fundamental Astro-Physics, 20-22 September at GSSI in L’Aquila

Gravitational wave observations of binary mergers are carrying a new revolution in astrophysics. While signals detected by ground based detectors have already shed light on the most violent among astrophysical events, next generation of interferometers like LISA will allow to witness the evolution of new families of sources, as asymmetric binaries, which harbour a unique potential for the identification of new fundamental fields and particles.

Intermediate-Mass Black Holes: The dawn of a revolutionary era, December 2-5 2023, San Pedro, Belize

Scientific Topic In this meeting we aim to explore the various observational and theoretical aspects of intermediate-mass black holes, and their unique role in: (1) Cosmology and galaxy evolution; (2) Formation of gravitational wave sources; (3) Accretion, tidal disruption events, and high-energy phenomena. The workshop aims to serve as a focal point for researchers working on intermediate-mass black holes on all scales, to connect theorists and observers, and to link together and share knowledge and tools between groups working on similar questions.
