The 13th LISA Cosmology Working Group Workshop will take place in Barcelona on June 1-5, 2026.
This workshop aims to bring together the LISA Cosmology community to discuss recent developments in cosmology relevant to LISA, together with advances in LISA science relevant to cosmology.
Ample time will be devoted to discussion sessions aimed at fostering new and ongoing collaborative projects and addressing outstanding questions in LISA cosmology.
Confirmed invited speakers: Diego Blas, Giulia Cusin, Daniel Figueroa, Juan Garcia-Bellido, Srashti Goyal, Otto Hannuksela, Henri Inchauspe, Antonio J. Iovino, Danny Laghi, Macarena Lagos, Konstantin Leyde, Eric Madge, Alberto Mangiagli, Germano Nardini, Mauro Pieroni, Carlos Sopuerta, Juan Urrutia, Luka Vujeva, Jeremy Wachter
Topics of discussion include:
-
Gravitational wave backgrounds from the early universe
-
Detection challenges for stochastic backgrounds searches
-
Characterization of isotropic and anisotropic GWB components
-
Standard sirens and cosmological tests of the late universe
-
Cosmological probes of general relativity and non-standard paradigms
-
Primordial black holes and dark matter
-
Gravitational-wave lensing
- Synergies with the Einstein Telescope, LVK, and searches at ultra-high frequencies
Important dates:
- Abstract submission deadline: April 17, 2026
- Registration deadline: May 1, 2026
There is no Registration fee.
The workshop is restricted to LISA CosWG members. Non-members interested in participating must write to membership@lisamission.org (with chairscoswg@gmail.com in cc).
