Dark Matter and Stars, July 14-16 2025, Kingston, Ontario, Canada

The International Conference "Dark Matter and Stars: Multi-Messenger Probes of Dark Matter and Modified Gravity" aims to bring together scientists working across the different research fields of astrophysics, cosmology, and modified gravity. We want to look at the dark matter problem from different perspectives, considering it to be of particle nature, as well as modification of gravity. This meeting is intended to initiate cross-field discussions of dark matter searches, their current status, and future prospects.

Conference Topics

  • Dark matter in compact stars (neutron stars, white dwarfs, exotic stars)
  • Multi-messenger and gravitational wave probes of dark matter
  • Supernovae and dark matter
  • Exoplanets and brown dwarfs
  • Models of dark matter
  • Cosmology
  • Modified gravity

We seek to encourage dialogue between different research groups to enhance collaboration and help to improve our understanding of dark matter. The conference is also planned to introduce the dark matter research field to encourage attendance by young scientists including Ph.D. students.

The meeting will be held at the Queen’s University, in Kingston, Ontario, Canada. Registration opens at 8:00 AM on Monday morning in the Biosci Atrium (116 Barrie St).

33rd Texas Symposium on Relativistic Astrophysics,December 8-12 2025 in Tempe

The 33rd Texas Symposium on Relativistic Astrophysics will take place in the vibrant city of Tempe, AZ, from December 8 – 12, 2025. The event will be hosted at The Omni Hotel, very near Arizona State University, which offers state-of-the-art facilities to ensure a productive and enjoyable meeting.

We are thrilled to announce that John Mather, Jim Peebles, Adam Riess, George Smoot (TBC), and Frank Wilczek have already agreed to participate and attend the symposium.

Beyond the symposium, Tempe in December offers a perfect blend of outdoor adventures and festive activities, making it an ideal winter getaway. The mild temperatures invite visitors to explore the scenic beauty of Tempe Town Lake, hike the iconic Hayden Butte, or stroll through the Desert Botanical Garden. You can also experience the Tempe Fantasy of Lights Boat Parade, a dazzling display of holiday lights along the lake. The city hosts various seasonal events, including holiday markets, outdoor concerts, and ice skating rinks, offering attendees a chance to enjoy the warm desert climate while celebrating the holiday season.

The symposium will cover all major topics on high-energy and particle astrophysics, cosmology, and relativity. It will include morning plenary sessions and afternoon parallel sessions, which will function as mini-symposia in each sub-field. The plenary sessions will consist of ~45-minute review talks. The afternoon sessions will feature oral talks (about 15-30 minutes) and poster contributions. Registration will open in early May.

We look forward to welcoming hundreds of international astronomers and physicists to Arizona in December 2025!

First International Latin American Conference on Gravitational Waves: 10 years since first detectionSeptember 15–19 2025 at INPE Sao Paulo

A decade ago, science witnessed an extraordinary milestone: the first direct detection of gravitational waves, predicted by Albert Einstein in his Theory of General Relativity in 1915. These ripples in spacetime, generated by extreme cosmic events such as black hole mergers, remained merely a theoretical prediction until September 14, 2015, when the LIGO (Laser Interferometer Gravitational-Wave Observatory) experiment captured this historic signal.

This achievement revolutionized astrophysics and earned the 2017 Nobel Prize in Physics for Rainer Weiss, Barry C. Barish, and Kip S. Thorne, recognizing their essential contributions to the design and implementation of LIGO, as well as the data analysis that confirmed the phenomenon.

The First International Latin American Conference on Gravitational Waves celebrates this milestone by bringing together researchers from across Latin America to discuss advancements in detection, theory, and instrumentation in the field of gravitational waves. Moreover, the event serves as a unique opportunity to unify and strengthen the Latin American scientific community, fostering institutional partnerships and collaborations that solidify the region’s presence in this cutting-edge field of science.

With a comprehensive program, the conference will feature lectures by renowned experts, technical sessions, discussion panels, and presentations of recent research. The primary goal is to foster the growth of the Latin American scientific community and encourage international cooperation, promoting regional leadership in a field that shapes our understanding of the universe.

10 Years of Gravitational Wave Discovery: Advancing the Frontiers of Gravitational Physics, October 6-10, 2025 at IIT Gandhinagar

The detection of gravitational waves in 2015 marked a groundbreaking milestone in science, not only confirming a key prediction of Einstein's General Theory of Relativity but also opening the door to an entirely new era of astrophysical exploration. India is contributing significantly to this global endeavor through the LIGO-India initiative - a mega science project on Indian soil, which aims to establish a gravitational wave observatory as part of the international network dedicated to detecting and studying these ripples in spacetime.

To commemorate the 10th anniversary of this historic scientific achievement, a dedicated discussion meeting is planned at IIT Gandhinagar. The event will serve as a
platform to reflect on past achievements, and explore future prospects in gravitational wave research.

IAU Symposium 398: Compact Objects and Binaries in Dense Stellar Systems, June 16-20, 2025, Seoul

Cluster dynamics and the evolution of single and binary stars are closely intertwined, leading to different scenarios than those in the galactic field. Star clusters serve as dynamic factories for all these intriguing objects, and these topics are inherently interconnected. 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, and compact objects (including binaries containing them) in dense star clusters. 2025 will be an excellent time to delve into the topic of star clusters and the roles of compact objects as it 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, ASKAP, 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.
