Luca Visinelli

Assistant Professor of Theoretical Physics (RTT)

University of Salerno and INFN (Italy)

Research profile

I am a theoretical physicist at the University of Salerno and INFN working at the interface of particle physics, astrophysics, and cosmology. I use the Universe and precision experiments as laboratories for new fundamental physics, with particular emphasis on axions and ultralight particles, dark-matter substructure, black holes, gravitational waves, and dark energy.

My research connects early-Universe dynamics and nonlinear structure formation to concrete observables in haloscopes, radio telescopes, gravitational-wave detectors, atomic sensors, and cosmological surveys. I coordinate the Theory Work Package of FLASH and co-developed ASTRA, a radio programme searching for axion conversion in neutron-star magnetospheres.

Before joining Salerno in 2025, I was a Tenure-track Associate Professor at Shanghai Jiao Tong University and a Fellow at the Tsung-Dao Lee Institute, a Marie Skłodowska-Curie FELLINI Fellow at INFN Frascati, a GRAPPA Fellow at the University of Amsterdam, and a postdoctoral researcher at NORDITA in Stockholm.

My work has received the 2021 Buchalter Cosmology Prize (Third Prize) and an NSFC Research Fund for International Excellent Young Scientists for the project Astrophysical Axion Laboratories.

Research leadership and experiments

Theory connected to instruments, observing programmes, and international collaborations.

My work increasingly connects fundamental theory to experimental design, signal modelling, and observational strategy.

FLASH

Resonant searches at INFN

At INFN Laboratori Nazionali di Frascati, I coordinate the Theory Work Package of FLASH, developing the modelling and interpretation of axion and high-frequency gravitational-wave signals in a resonant haloscope.

ASTRA

Radio searches for axions

I co-developed ASTRA, a radio search for QCD-axion conversion in neutron-star magnetospheres. The programme links theory, telescope strategy, and signal modelling across a multi-year observing campaign.

OBSERVATIONS

Telescope and gravitational searches

I initiated Green Bank Telescope searches for axions in Andromeda and contribute to broader efforts using resonant detectors, atomic sensors, and multimessenger observations to test ultralight physics.

Scientific responsibilities in the full CV

Selected publications

Foundational contributions and recent directions.

Group and opportunities

Training researchers across theory, computation, and experiment.

I supervise projects spanning axion phenomenology, cosmology, compact objects, gravitational waves, and data analysis for experimental searches. Students are encouraged to connect formal modelling with observables, build reproducible numerical tools, and collaborate internationally.

JOIN THE GROUP

Prospective students

I welcome enquiries from motivated MSc and PhD students interested in theoretical astroparticle physics. A useful first message includes your CV, transcript, research interests, and the timescale or funding route you are considering.

COLLABORATION

Research environment

Projects are based at the University of Salerno and INFN and can involve collaborators in FLASH, telescope programmes, Virgo/LVK, and partner institutes across Europe, China, and the United States.

Teaching

From first principles to research questions.

My courses connect the mathematical foundations of cosmology and gravitation to current research in dark matter, dark energy, and gravitational waves. Public notes and slides are intended for advanced undergraduate and graduate students.
