Solar axion searches with RES-NOVA: projected sensitivity and first prototype limit
D. Alloni, G. Benato, P. Carniti +49
RES-NOVA is a cryogenic experiment based on PbWO4 scintillating bolometers produced from archaeological lead, originally designed to detect coherent elastic neutrino-nucleus scatte…
How invisible can QCD axions be? From Supernova emission to Cherenkov signals
Luca Di Luzio, Vincenzo Fiorentino, Maurizio Giannotti +2
We investigate the scenario of maximally invisible axions, namely QCD axions whose interactions with matter arise exclusively from the irreducible coupling to gluons responsible fo…
Neutron Star Bounds on Muonic Fifth Forces from Picometer to Meter Scales
Damiano F. G. Fiorillo, Alessandro Lella, Georg G. Raffelt +2
Testing muonic fifth forces is difficult because muons are scarce in ordinary matter. However, they are abundant in neutron stars. We show that this population responds coherently…
Production of Leptophilic Bosons in Ultradegenerate Relativistic Matter
Damiano F. G. Fiorillo, Alessandro Lella, Georg G. Raffelt +2
Neutron stars (NSs) are powerful factories for new particles with masses up to the 100~keV range. These compact stars contain significant amounts of protons, electrons, and muons.…
Multimessenger probes of Axions from Compact Objects
Alessandro Lella
Astrophysics plays a pivotal role in the quest for axions and axion-like particles, offering guidance to experimental efforts and enabling the investigation of axion properties tha…
Lectures on Light Particles and Compact Objects
Alessandro Lella, Jamie McDonald
This document is based on lectures delivered at a recent COSMIC WISPers COST Action training school in Annecy in September 2025. They examine detection of weakly interacting slim p…
Gravitational-Wave Signals for Supernova Explosions of Three-Dimensional Progenitors
Alessandro Lella, Giuseppe Lucente, Daniel Kresse +3
Core-collapse supernovae (SNe) are sources of gravitational waves (GWs) produced by hydrodynamical instabilities and highly time-dependent anisotropies of the neutrino radiation. I…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Axions at the meV Crossroads: Theory, Cosmology, Astrophysics, and Experiments
Michele Cicoli, Francesco D'Eramo, Luca Di Luzio +18
The meV mass range has emerged as a focal point in axion physics, where advances in theory, cosmology, astrophysics, and experimental techniques converge. Axions in this mass range…
Search for Axion-Like Particles from Nearby Pre-Supernova Stars
Saurabh Mittal, Thomas Siegert, Francesca Calore +7
Axion-like particles (ALPs) are hypothetical pseudoscalar bosons that arise in many extensions of the Standard Model and are well-motivated dark matter candidates. Nearby massive s…
Detecting light axions from supernovae in nearby galaxies
Francesca Lecce, Alessandro Lella, Giuseppe Lucente +2
Axion-like particles (ALPs) coupled to nucleons can be efficiently produced in core-collapse supernovae (SNe) and then, if they couple to photons, convert into gamma rays in cosmic…
Leading bounds on micro- to picometer fifth forces from neutron star cooling
Damiano F. G. Fiorillo, Alessandro Lella, Ciaran A. J. O'Hare +1
The equivalence principle and the inverse-square law of gravity could be violated at short distances ( to meters) by scalars sporting a coupling to nucleo…

Francisco R. Candón, Sougata Ganguly, Maurizio Giannotti +3
Protoneutron stars, highly compact objects formed in the core of exploding supernovae (SNe), are powerful sources of axion-like particles (ALPs). In the SN core, ALPs are dominantl…
