DTP/TALENT 2024, Nuclear Theory for Astrophysics, July 15 – August 2 2024, Trento

Nuclear physics and astrophysics are strongly linked through neutron stars, compact objects that represent the densest form of matter in the universe. Neutron stars also have strong synergies to nucleosynthesis and the origin of the heaviest elements in the cosmos. This TALENT school will cover: 1) the equation of state of neutron-rich matter and new constraints inferred from nuclear theory, experiment and observations, 2) core-collapse supernova as the birthplace of neutron stars, and 3) neutron star mergers and gravitational waves to probe the neutron-star interior. In the last years, there has been an enormous progress in theory, experiments, and observation and we aim to bring to the students a broad overview combined with concrete and practical exercises to achieve a comprehensive understanding of neutron stars from the nuclear and astrophysics perspectives.

TOPICS and SCHEDULING
Week one: Nuclear physics of neutron stars

The lectures will explain how to build an equation of state for neutron rich matter that is consistent with known properties of finite nuclei and neutron stars. The students will learn how to build a TOV solver in order to compute the mass-radius relation for a small sample of realistic equations of state. The lectures will conclude with some of the important open questions in the field.

Week two: Birth of neutron stars in core-collapse supernovae.

We will briefly review the stellar evolution of massive stars and discuss in detail their collapse and explosions as supernovae. The students will gain a deep understanding of the explosions and the role of the equation of state on the supernova dynamics, neutrino emission and nucleosynthesis. The seminars will cover neutrino astrophysics and the role of magnetic fields in supernovae.

Week three: Neutron star mergers

Lectures and tutorials will focus on numerical relativity simulations of neutron star mergers where the students will also familiarize themselves with some open source codes used in the community. The lectures will also cover our current understanding of the gravitational and
electromagnetic emission that can be produced by these systems, including r-process/kilonova and short gamma ray bursts.

Gravitational Wave Orchestra in the Alps, September 17 – 19, 2024, Annecy

The second edition of the "Gravitational Wave Orchestra" in Annecy, following a first event in Louvain-la-Neuve in September 2022.

The idea of this series of workshops is to bring together international experts on the stochastic gravitational background. This background is the gravitational signal created by the ensemble of all sources, from the earliest instants of the Universe, that are too distant or too faint to be detected individually. We can think of an orchestra in which each instrument plays its own melody, and together form a symphony.

This conference aims to highlight the most recent advances and discoveries in this rather specialized field, with an emphasis on theory and data analysis. The format, which leaves plenty of time for discussion, encourages exchange. We are also planning tutorial sessions on the data analysis methods used by the various gravitational wave collaborations, LIGO-Virgo-KAGRA, LISA, Pulsar Timing Arrays and cosmic microwave background experiments.

The social events will be a conference by the artist Jan de Coninck on his project “the triangle”, which remind the Einstein Telescope and LISA, and a dinner cruise on the beautiful Annecy lake.

Fundamental Physics Meets Waveforms With LISA, September 2-6 2024, at AEI Potsdam

With the recent adoption of the LISA mission by the European Space Agency, we have entered a new exciting phase. Now, more than ever, there is a need to prepare the theoretical and data-analysis tools that will allow us to fully exploit LISA’s capabilities, and probe strong gravity and fundamental physics in unprecedented ways.

With that in mind, we are pleased to announce an in-person meeting of the Fundamental Physics and Waveform Working Groups of the LISA Consortium. The workshop is hosted by the “Astrophysical and Cosmological Relativity” division at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) in Potsdam, Germany.

The first two days of the meeting, September 2-3, will be dedicated to talks and discussions on ongoing and possible future projects carried out within the Fundamental Physics Working Group. The focus will be on identifying the theoretical developments and the data-analysis tools needed to perform strong-field tests of General Relativity with LISA.

The third day of the meeting, September 4, is organized jointly by the Fundamental Physics and Waveform Working Groups and aims at brainstorming on common needs and goals since waveforms are the “bread and butter” for extracting information about the nature of black holes, their environment, and gravity.

The final two days of the meeting, September 5-6, will be dedicated solely to the Waveform Working Group. The objective is to identify significant waveform developments for various gravitational-wave sources, necessary for LISA data validation and science exploitation.

The workshop is limited to 70 participants on any given day, except Wednesday, where we aim at 140 participants. Register now!

12th Aegean Summer School, September 9-14, 2024, Sifnos, Greece

The aim of the 12th Aegean Summer School is to discuss the recent developments in theory in Gravity and Cosmology and in observations discussing the LIGO, VIRGO, LISA and BINGO experiments.

The 12th Aegean Summer School will take place in the town of Apollonia in the island of Sifnos, in the Cultural Centre “Marianthi Simou” and it is organized and sponsored by the National Technical University of Athens, Greece, the University Paris-Sud, Orsay, France, the University of Tuebingen, Germany, the University Nottingham, England, the University Sapienza, Rome, Italy, the University Pontificia Universidad Católica de Valparaiso, Chile, the University Sao Paulo, Brazil and the European Cooperation in Science and Technology (COST).

One of the most successful theory describing cosmic objects, their interactions and their time evolution, is the Einstein’s theory of Gravity. One of the main prediction of the Gravity theory is the existence of Gravitational Waves (GW), the ripples of space-time. The latest GW detections by ground-based interferometers and the discovery of a binary pulsar whose orbital period changes in accordance with the predicted GW emission, verified the predictions of the Einstein’s theory and opened up an intensive activity of understanding all aspects of the GWs and the implications of this discovery to alternative theories of Gravities and their Cosmological implications.

The modified gravity theories can give us important information on the structure and properties of the compact objects predicted by these theories and also the observational signatures which they can introduce. It is expected that future ground and space-borne detectors will improve our perception of gravitational interactions in particular will shed light into the existence of exotic compact objects, like hairy black holes and wormholes. These compact objects provide a window into the microscopic structure of spacetime in Quantum Gravity and the hope is to understand the nature of their interior, potential applications to Quantum Cosmology, and the development of further connections to quantum information and laboratory quantum simulation. The formation of these compact objects may also trigger possible holographic phase transitions to other compact objects.

Enabling Future Gravitational Wave Astrophysics in the Milli-Hertz Regime, 30 June – 25 July 2025, Garching

Join us to explore the uncharted milli-Hertz regime of the gravitational wave spectrum, a domain soon to be unlocked by space missions. With a special emphasis on the Laser Interferometer Space Antenna (LISA) mission, our workshop also broadens its scope to include other milli-Hertz missions and aims to explore synergies with the next generation of ground-based gravitational wave detectors.
Valeriya Korol, Natalia Korsakova, Lucio Mayer, Martina Toscani, Niels Warburton

The milli-Hertz regime is unique due to the variety of gravitational wave sources emitting at these frequencies, including binaries of stellar remnants such as white dwarfs, neutron stars, and black holes within our own Galaxy, as well as inspiraling compact objects onto massive black holes (aka Extreme/Intermediate Mass Ratio Inspirals, E/IMRI) and mergers between nascent massive black holes (MBH) at cosmic dawn. This regime is also unique in terms of waveform modelling, data analysis and data interpretation, presenting challenges that call for a community-driven approach.

Our workshop will bring together leading experts and early career scientists in the field of theoretical modelling (from astrophysics to numerical relativity), electromagnetic observations, and gravitational wave data analysis, aiming to prepare the community for the new kind of gravitational wave data and to enable groundbreaking astrophysics in the milli-Hertz regime. The format will balance scientific talks, interactive tutorials, and open discussions, creating an ideal environment for initiating new collaborations and consolidating ongoing projects. More broadly, we strive to foster a community where interdisciplinary and creative collaborations can flourish.

Key questions to be discussed include:

  • Utilising electromagnetic observations of Galactic binaries for instrument noise estimation.
  • Identify waveforms that effectively capture the diversity and complexity of astrophysical populations for each source type while optimising computational efficiency.
  • Formulate astrophysically motivated priors for the global fit analysis.
  • Discuss strategies for extracting astrophysical sources from GW data to analyse stochastic signals.

Week 4 (21st – 25th July): Data Interpretation via Astrophysical Models

  • Build upon insights from previous weeks’ discussions to explore the scientific interpretation of mHz GW data using astrophysical models.
  • Develop astrophysics-focused mock data challenges to prepare the community for future data interpretation.

Key questions to be discussed include:

  • Re-discovering our Galaxy using mHz GW detections.
  • Understanding MBH formation through GW detections.
