GRASS 2026 – GRAvitational-wave Science&technology Symposium, Padova, Italy

The 5th GRAvitational-wave Science&technology Symposium (GRASS 2026) will be held in Padova (Italy) on 22 - 24 June 2026.

The GRAvitational – wave Science&technology Symposia (GRASS) are a series of meetings aimed at exploring the panorama of gravitational-wave related experimental science beyond the next decade; special emphasis is given to open issues and key enabling technologies at the forefront of the most advanced detection techniques. It represents an informal and unique meeting occasion for experts from different fields involved in experimental aspects of future gravitational-wave science and technology.

The GRASS 2026 edition will include topical sessions on advanced optical coatings and material development, modelling and mitigation of stray light noise, reduction of quantum noise and artificial intelligence applications to gravitational waves detectors.
A general session to discuss any other open issue is foreseen as well.

The Symposium is organized by the INFN Padova Unit, with the support of INFN and under the patronage of the Physics and Astronomic dpt. of Padova University.

BritGrav 2026, April 9-10 in Cardiff

The 26th BritGrav meeting will be hosted by the Gravity Exploration Institute at the School of Physics and Astronomy at Cardiff University.

The meeting will be held on the 9th and 10th of April 2026.

The aim of BritGrav is to bring together early-career researchers working on all aspects of gravitational physics, including astrophysics, cosmology, general relativity, quantum gravity, gravitational-wave data analysis and instrumentation.

Following the BritGrav tradition, the meeting will consist of short talks, with priority given to PhD students and postdocs. The meeting has no registration fee. Limited funding will be available from the IOP Gravitational Physics Group to support travel for PhD students based in the UK and Ireland. You may request travel support by emailing the organisers.

CosmoVerse@Bilbao 2026, September 15-19

Our understanding of the Universe is at a turning point with the predictions of the standard cosmological model and the observations from different surveys are showing tensions in several key areas. The disagreement is expressed in the value of cosmic expansion as well as in the growth of large-scale structure in the Universe. New cosmological surveys, many of which are European, may expose tension in additional areas of the concordance model. The question of cosmological tensions can be confronted in a number of ways. Firstly, survey data needs to be further analyzed for potential systematic uncertainties or biases. Secondly, there have been numerous advances in approaches to data analysis and statistics, some of which provide less dependence on cosmological models to make cosmological parameter estimates. Lastly, there are a plethora of new proposals from fundamental physics which range from novel neutrino physics to dark energy proposals (and others) which may contribute to a solution to the cosmological tensions problem. These represent the three research themes through which cosmological tensions will either be alleviated or resolved.

4th LISA Sprint, May 11-13, 2026 in Bozeman, Montana

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 4th LISA Sprint in Bozeman, Montana, from Monday May 11 to Wednesday May 13, 2026.

In past LISA Sprints the participants all pitched project ideas at the workshop, and teams selecting the projects they wanted to work on. This time will be a little different. While additional project pitches are still welcome, the focus will be on several pre-defined projects that have been identified as critical needs by the NASA Science Ground Segment team. Participants will be asked to list their preferences for which of the pre-define projects they would be most interested in contributing to in advance of the workshop.

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

In late January 2026 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.

16th International LISA Symposium, June 21-26, 2026, College Park, Maryland

We welcome you to the 16th International LISA Symposium! Continuing from past editions, the Symposium will highlight gravitational wave astrophysics, with a primary focus on the most up-to-date mission development, theory and analysis enabling the science to be done with the Laser Interferometer Space Antenna. The Scientific Organizing Committee is planning an engaging program of invited talks and special sessions to be complemented by your contributions of talks, posters, questions and discussions. We look forward to bringing together a wide cross-section of the international community, including students (with a discounted registration fee).

The Symposium will take place on the University of Maryland campus in College Park, Maryland, USA, beginning with registration and a welcome reception on the evening of Sunday, June 21. Scientific sessions (plenary, parallel and poster) will be held Monday through Friday, June 22 to 26, ending in the mid-afternoon on Friday. Breakfast and coffee breaks will be in the room where posters are displayed. A public lecture is being planned on Tuesday evening. Following tradition, Wednesday afternoon is kept open and a variety of local activities, ranging from organized to informal, will be available depending on your interests; details will be posted on this website.

We recognize the constraints and concerns about international travel and want to support scientists who are unable to attend in person while still maintaining the value of a lively in-person meeting. While remote attendance will be possible, the number of remote presentations will be limited and the selection of submitted abstracts will prioritize in-person talks and posters. Maryland prides itself on being a welcoming state and a home to many cultures, and we hope you will take part in symposium if you are able to.

Registration and abstract submission are now open. You may submit an abstract and register (and pay) all at once, or at different times.

WE Heraeus Physics School und 62. Karpacz Winter School in Theoretical Physics “Multimessenger Astrophysics and Cosmology”, February 28 – March 6 2026 in Karpacz

The WE Heraeus Physics School and the 62nd Karpacz Winter School in Theoretical Physics "Multimessenger Astrophysics and Cosmology" will be held from 28 February to 6 March 2026.

Compact stars, dense remnants of supernovae, compress about 1.4 solar masses into a 10 km radius—reaching densities beyond atomic nuclei. Their extreme compactness makes them unique laboratories for high-density matter. Gravitational-wave detections of binary neutron star mergers now allow direct probes of such conditions, with hot, dynamic post-merger remnants offering complementary insight to cold pulsars.

With next-generation observatories like the Einstein Telescope and Cosmic Explorer, multi-messenger astrophysics—combining gravitational waves, electromagnetic signals, and neutrinos—will sharpen constraints on the dense-matter equation of state, extreme gravity, and heavy-element nucleosynthesis. Mergers also serve as standard sirens, enabling independent measurements of the Hubble constant.

The school will cover the thermal history of the Universe after its first second, from the quark–hadron transition to neutrino decoupling, linking microphysics to cosmological observables. Topics include the Hubble tension, modified gravity, primordial magnetic fields, compact-object mergers, future gravitational-wave science, and primordial black holes as dark-matter or galaxy-seed candidates—offering a unified view across astrophysics, cosmology, and particle physics.
