[Users] First Circular of Workshop on the “New Frontiers in Strong Gravity IV” in Benasque in July 2026.

[Helvi Witek]

Dear colleagues,

The fourth installment of the two-week workshop “New frontiers in strong 
gravity” will take place in Benasque, Spain, from 19–31 July 2026 at the 
Science Center in Benasque 
(https://benasque.org/new_general/cgi-bin/years.pl?ano=2026 
<https://urldefense.com/v3/__https://benasque.org/new_general/cgi-bin/years.pl?ano=2026__;!!DZ3fjg!9g32cx5BrYn7gFyI0VOlfXI5guLtbBvt14vI70CZG17PDB6DzZ-z-7ujvRybLEi93RRbaymAup7XZO8$>) 
in the Spanish Pyrenees. The registration will open in Spring 2026.


The goal of the workshop is to foster new ideas and collaborations by 
bringing together experts across different disciplines, including 
gravity, gravitational wave astrophysics, numerical and mathematical 
relativity. We plan for only two talks per day, with ample time for 
informal discussions, sessions and collaborations. We aim at creating a 
diverse and inclusive meeting that thrives through communication and 
discussion, and we would greatly welcome participation and contributions 
from different communities, as well as researchers at different career 
stages.


Topics planned for this installment include:


  *

    Precision GW modeling

  *

    Future GW facilities

  *

    New detector proposals (atom IFOs, lunar, high frequency, deciHz,
    μHz) and sources

  *

    Future data analysis

  *

    Tests of beyond-GR

  *

    Cosmology

  *

    PBHs/Memory Burden

  *

    Formal mathematical relativity, perturbative methods (PN, PM)

  *

    Memory, tails, other soft effects

  *

    Analog gravity

  *

    Environmental effects (dark matter halos, accretion disks)

  *

    Scattering and Amplitudes

  *

    Developments in quantum gravity

  *

    New developments in NR / GPU computing


We would appreciate it if you could kindly note the dates if you plan to 
attend and forward the announcement to interested researchers in our field.


We look forward to welcoming you to Benasque.


On behalf of the organisers (D. Blas, P. Figueras, S. Nissanke, L.
