What Naturalness Measures: Fine-Tuning and Informational Invariants in Cosmology and Dark Matter
Stefano Profumo
Naturalness is commonly presented as an objective constraint on physical theories: a model requiring fine-tuning is judged implausible. This presentation conflates a representation…
Charting Dark Matter down to the neutrino floor/fog in the 2HD+a scenario
Giorgio Arcadi, Abdelhak Djouadi, Stefano Profumo
Next-generation direct detection experiments will probe dark matter (DM) scattering cross-sections deep into the neutrino fog, the regime where coherent neutrino scattering becomes…
Cosmology as Representation: Informational Invariance and the Limits of Scientific Realism
Stefano Profumo
Modern cosmology is often taken to provide an increasingly accurate description of the universe's underlying ontology through progressively refined mathematical models. I challenge…
Are Primordial Black Holes a Natural Dark Matter Candidate?
Stefano Profumo
Primordial black holes (PBHs) in the asteroid-mass window (- g) can account for all of the dark matter without violating any observational constraint, yet are rou…
Primordial black holes versus their impersonators at gravitational wave observatories
Andrea Begnoni, Stefano Profumo
The detection of primordial black holes (PBHs) would mark a major breakthrough, with far-reaching implications for early universe cosmology, fundamental physics, and the nature of…
G objects as Primordial Black Hole-Neutron Star Remnants: Population Modeling and Multi-Wavelength Observables
David Morales-Zapien, Stefano Profumo
The nature of the so-called G objects orbiting the Galactic Center remains unresolved. These sources exhibit compact Br emission, extreme infrared colors, and remarkable dynami…
