SN2025gw: First IGWN Symposium on Core Collapse Supernova Gravitational Wave Theory and Detection

(posted here May 09, 2025)

SN2025gw: First IGWN Symposium on Core Collapse Supernova Gravitational Wave Theory and Detection, Warsaw, Poland, July 21-25, 2025.

The LIGO-Virgo-KAGRA Collaboration invites the core-collapse supernova (CCSN) astronomy and astrophysics community for a 5-day Symposium on July 21-25, 2025, at the University of Warsaw, Poland. CCSNe are among the most violent explosions known to occur in the Universe, and the next Galactic or near extra-Galactic exploding massive star will be one of the most interesting, and most important, astronomical events of the century. This Symposium aims to bring CCSN experts together to address how to maximize the scientific potential of the first detection of core collapse supernova gravitational waves (GWs). The Symposium hopes to bring together GW astronomers and CCSN modelers, as well as neutrino and nuclear theorists, neutrino astronomers, and astronomers across the electromagnetic spectrum.

The sensitivity of GW detectors and progress on CCSN modeling are unprecedented, and we expect them to further advance in the coming years. A joint effort across communities has great potential to fully utilize these advances for CCSN GW discovery. Each day, we will host (before lunch) a set of lectures on one of the key topics listed below, to establish a common understanding and a common language. Moreover, each day (after lunch) will also include invited and contributed talks, as well as discussion. The focus topics of the Symposium are:

Day 1: CCSN Theory
Day 2: CCSN Gravitational Wave Detection and Parameter Estimation
Day 3: CCSN Neutrino Detection
Day 4: CCSNe across the Electromagnetic Spectrum
Day 5: CCSNe over the Next Ten Years

The proceedings of the Symposium will be published in a special issue of Classical and Quantum Gravity. We hope the proceedings will serve as a reference for students, postdocs, and faculty in, or entering, the field, serve to capture the current state of core collapse supernova gravitational wave astronomy and astrophysics, outline lessons learned, and provide recommendations for future development.

Everyone who wishes to advance the field of CCSN GW science is welcome!

IAU Symposium No. 398: Compact Stars and Binaries in Dense Stellar Systems

(posted here February 14, 2025)

IAU Symposium No. 398: Compact Stars and Binaries in Dense Stellar Systems
Conference Webpage: https://gravity.snu.ac.kr/iaus398


We are pleased to announce the International Astronomical Union Symposium 398 “Compact Objects and Binaries in Dense Stellar Systems” which will take place June 16-20, 2025, in Seoul National University, Seoul, Korea. This meeting will also be held as MODEST-25, annual workshop series for Modeling and Observing Dense Stellar Systems.

This symposium is intended to discuss the astrophysical origin of gravitational waves and to establish connections between theoretical and observational data concerning dynamics, populations, binaries, multiples, compact objects (including binaries containing them) in dense star clusters. Star clusters serve as dynamical factories for all these intriguing objects, and these topics are inherently interconnected. For instance, cluster dynamics and the evolution of single and binary stars are closely intertwined, leading to different scenarios compared to those in the galactic field. We believe that the year 2025 is an appropriate time to delve into the topic of star clusters and the roles of compact objects. This timing aligns with the release of significant results from the fourth observing run of LIGO/Virgo/KAGRA, which should provide crucial new constraints on the formation of gravitational wave sources. Additionally, numerous new discoveries of globular cluster pulsars are!
expected from large radio facilities such as MeerKAT, ASKving DeAP, FAST, and others. New computer codes for dynamical simulations of dense star clusters are also emerging, and this symposium offers an excellent opportunity to discuss the latest results based on these codes.

Abstract Submission and Registration Information:
Abstract submission is now open and will close on April 15 for oral presentations and May 15 for poster presentations. Please submit your abstracts via the conference homepage.

The program is scheduled for August 3-24, 2025. The application deadline is January 31, 2025; see https://aspenphys.org/summer-workshops/. We invite you to apply. Please also encourage other people who are active in the field to apply.

Be aware that we cannot guarantee admission to the workshop. Admission to the workshop is granted not by the workshop organizers, but by the Admissions Committee of the Center. Because of the constraints imposed by the rest of the Aspen Center for Physics program, they are usually not able to admit everyone who applies.

Aspen Center for Physics encourages participants, especially those early in their careers, those with families, and those from underrepresented groups, institutions, and countries, to apply for our summer program. The Center has a limited amount of additional financial support for participants who fall into these, and other, special categories and encourages applicants who need financial support to apply for it on their application.

Best,

Kimberly Boddy

11th Gulf Coast Gravity Meeting

(posted here December 20, 2024)

The GCGM returns to the University of Mississippi! The 11th Gulf Coast Gravity Meeting will be held at the University of Mississippi in Oxford, MS, on April 11 and 12, 2025. In keeping with its tradition, this will be an open, relaxed, and informal conference. We are inviting researchers and students interested in all areas of gravitational physics: classical and quantum gravity, general relativistic astrophysics and cosmology, quantum cosmology, gravitational waves, and experimental gravity. Because this is a regional meeting, many attendees will be from the southeastern United States, but all are welcome.

Talks

Following the usual tradition all participants, and especially postdocs and graduate students, are encouraged to contribute short, introductory talks on their current research, with the aim of fostering communication and understanding among gravitational physicists with different backgrounds. A prize (sponsored by the APS Division of Gravitational Physics) will be awarded for the best talk given by a student at the meeting.

Deadlines

Prospective speakers should register by March 01 to receive full consideration. Late applicants will be considered at the discretion of the organizers. See the website for details: https://www.phy.olemiss.edu/gcgm11/.

Announcing the 3rd LISA Sprint

(posted here December 20, 2024)

The Laser Interferometer Space Antenna (LISA) is a joint effort of ESA and NASA to develop and operate the first space-based observatory of gravitational waves (GWs) in the millihertz frequency band. To prepare for LISA observations and its unique data products, we are organizing the 3rd LISA Sprint in Huntsville, AL, from Monday April 28 to Wednesday April 30, 2025.

The meeting's goals will be two-fold: The first goal is to connect LISA data scientists with astronomers and astrophysicists who will incorporate LISA data products into their own research. The second is to advance the broader research community’s readiness to capitalize on LISA observations.

The theme for this third meeting is Time Domain and Multimessenger Astronomy with LISA. During the workshop small interdisciplinary teams of researchers will come together and make concrete progress on concise projects and goals related to this scientific area. A number of project ideas and mock data and/or data products will be produced and provided by the organizers in collaboration with experts in the field. Additionally, participants are encouraged to propose ideas and contribute further material that adheres to the workshop’s format.

This will be a hands-on workshop: there will be no talks--only brief project “pitches” at the beginning of the workshop, and “show and tell” at the close of the meeting to share progress with the group.

In early January 2025 we will advertise the meeting website and application form for interested participants. Please note that space will be limited, so applying does not guarantee acceptance. Accepted applicants will be notified by the end of February. There is no financial support available to attend the meeting, nor is there any registration fee for participating.
