• Modelling of astrophysical sources of gravitational waves.This line of research encompasses the group's efforts in the numerical modeling of astrophysical sources of gravitational waves. It includes numerical relativity simulations of gravitational collapse (core collapse supernovae, black hole formation) and coalescences of compact binaries (black holes, neutron stars, and exotic compact objects such as boson stars), both in general relativity and modified gravity theories.
• Gravitational-wave data analysis.This line of research encompasses the group's efforts in data analysis of gravitational wave signals, both simulated and observed by the network of detectors of the LVK collaboration. It includes the generation of waveforms using numerical relativity simulations and generative artificial intelligence techniques; the estimation of parameters of the astrophysical sources that produce gravitational-wave signals (in compact binary coalescences and supernova explosions), using both Bayesian inference techniques and Deep Learning; the analysis of gravitational lensing effects on gravitational waves (including microlensing and exotic lenses such as cosmic strings); studies of gravitational-wave polarization; the characterization of detectors through the classification and denoising of non-astrophysical noise sources (glitches) using Deep Learning and Sparse Dictionary Learning techniques; and the participation in electromagnetic searches for counterparts of the gravitational-wave signals observed by the LVK collaboration.
• Contributions to Advanced Virgo.This research line encompasses the group efforts in the operations of the Advanced Virgo gravitational-wave detector. Our group participates in the commissioning of the Virgo detector upgrade, both in terms of characterizing its noise sources and in contributions to the instrumentation (such as the acquisition and purchase of ultra-high vacuum pumping stations to meet the design specifications of the detector). In addition, we also participate in the development of new pipelines for the LVK Collaboration's O5 campaign and for the Einstein Telescope, including pipelines for supernova signal detection, proto-neutron star inference, and detection of gravitational lensing effects in signals produced by black hole coalescences, among others. Finally, GWNR members are very actively involved in Advanced Virgo+ and Virgo Collaboration committees (in particular, the Virgo Steering Committee, the Virgo Executive Committee, and the Virgo Editorial Board), as well as in various service activities within the Bursts, CBC, and DetChar working groups, and in shifts for the Rapid Response Team and the Parameter Estimation ROTA, among others.
