Duvier Suárez Fontanella
PhD Candidate in Theoretical and Computational Astrophysics
Department of Fundamental Physics and Mathematics
University of Salamanca
I work on axion electrodynamics, compact objects, binary neutron-star systems, gravitational waves, and dark-matter searches with multimessenger signals.
Research profile
I am a final-year PhD researcher in theoretical and computational astrophysics at the University of Salamanca. My work focuses on compact objects as laboratories for dark-matter and astroparticle physics, with particular emphasis on neutron stars, gravitational waves, axion-like particles, and electromagnetic signatures of hidden-sector interactions.
My research trajectory connects the study of boson stars and gravastars with current work on dark matter in neutron stars, gravitational-wave observables, and ALP–photon couplings in strongly magnetized compact systems.
- Axion and ALP phenomenology in compact-object environments
- Dark-matter interactions in neutron stars and binary neutron-star systems
- Gravitational-wave probes of dark sectors
- Axion-photon conversion in magnetized astrophysical plasmas
- Numerical modeling, equation-of-state studies, and computational pipelines
Selected highlights
Compact objects as dark-sector laboratories
My current research investigates how neutron stars and compact binaries can encode signatures of dark matter, axion-like particles, and hidden sectors in gravitational-wave and electromagnetic observables.
Publications and collaborations
I have authored and co-authored several publications in relativistic astrophysics and astroparticle physics, including first-author works in Physical Review D and Physics Letters B, and I contributed to the Einstein Telescope Collaboration science case.
Scientific software
I develop numerical and data-driven tools for astrophysical modeling, including Python-based pipelines for axion electrodynamics, compact objects, dark-matter searches, and simulation post-processing.
