Friday 30 January

10:00 → 13:30 Joint meeting: Pheno morning (Note the special venue!)

10:30 Coffee

11:00 Effective Field Theory for Thermal Phase transitions

I will present recent progress in applying effective field theory (EFT) to the precise computation of thermal phase transition parameters and the associated gravitational wave spectra. I will also briefly comment on byproducts of this work, including new methods for two-loop renormalization in EFT that avoid gauge-breaking counterterms and infrared rearrangement.

Speaker: Mikael Chala (Universidad de Granada)

12:00 Lunch

13:30 → 17:00 Joint meeting: Gravitational wave afternoon (Note the special venue!)

13:30 Introduction to LISA, its data analysis challenges, and modelling of extreme mass ratio inspirals

Speakers: Bert Depoorter (KU Leuven), Robrecht Keijzer (KU Leuven)

14:45 The LISA mission and its distributed data processing center

Speaker: Antoine Petiteau (APC)

16:00 Listening to the millihertz universe: LISA data analysis and the challenge of extreme mass ratio inspirals

The Laser Interferometer Space Antenna (LISA) will open a new window onto the gravitational wave Universe by observing millihertz signals from massive black hole mergers, compact galactic binaries, and extreme mass ratio inspirals (EMRIs). Extracting these signals from a data stream shaped by instrumental noise and astrophysical confusion requires advanced data analysis strategies. In this talk, I will outline the main challenges of LISA data analysis. I will then focus on EMRIs: long lived, highly structured signals produced when stellar mass compact objects spiral into massive black holes. These sources encode precise information about spacetime geometry and black hole astrophysics, yet their detection and characterization demand accurate waveform models and scalable search algorithms. I will discuss recent progress in EMRI modeling and how emerging data analysis pipelines aim to unlock their unique scientific potential.
