Juan Calderon Bustillo

Juan Calderon Bustillo is a Ramón y Cajal Researcher at the University of Santiago de Compostela (USC), affiliated with the Galician Institute of High Energy Physics (IGFAE) in the Department of Particle Physics. He leads research within the TEOFPACC group, focusing on theoretical physics, gravitational wave astronomy, and astroparticle physics. His work addresses fundamental questions in black hole dynamics, neutron star mergers, and dark matter candidates using advanced numerical relativity techniques.

Calderon Bustillo holds a PhD from the Universitat de les Illes Balears (2015), where his thesis on gravitational radiation from compact binaries laid groundwork for hybrid waveform constructions. Supervised by Dr. Sascha Husa and Dr. Alicia Magdalena Sintes Olives, his research bridges theoretical models with observational data from LIGO, Virgo, KAGRA, and GEO600 detectors.

His research interests span gravitational wave signatures of mirror symmetry, ultralight boson mergers, and post-merger remnant properties. Key projects include analyzing recoil velocities in black hole mergers, probing dark matter through gravitational waves, and developing surrogate models for exotic compact object collisions. Calderon Bustillo has contributed to multi-messenger campaigns, such as Swift-BAT follow-ups of GW triggers, and searches for continuous gravitational waves from pulsars and magnetars.

His recent work emphasizes third-generation detector readiness, exploring thermal effects in neutron star mergers and constraints on vector dark matter. Collaborations with international teams like EuCAPT highlight his role in shaping next-decade astroparticle physics priorities, focusing on cosmological tests and dark sector interactions.
