Wide binaries in ultra-faint dwarf galaxies as a probe of extended dark objects
María Olalla Olea-Romacho
Wide stellar binaries are sensitive dynamical probes of dark matter substructure. We generalize existing point-mass disruption constraints to spherical extended dark objects and ap…
Inflationary Particle Production and Implications for WIMP Substructure
María Olalla Olea-Romacho
We explore the observational consequences of resonant particle production during inflation, focusing on its impact on dark matter annihilation signals today. A transient burst of p…
Can WIMPs Survive the Legacy of a Magnetised Early Universe?
María Olalla Olea-Romacho, Malcolm Fairbairn, Pranjal Ralegankar
Primordial magnetic fields (PMFs) can seed additional small-scale matter fluctuations, leading to the formation of dense, early-collapsing dark matter structures known as minihalos…
Benchmarking a fading window: electroweak baryogenesis in the C2HDM, LHC constraints after Run 2 and prospects for LISA
Thomas Biekötter, María Olalla Olea-Romacho
The origin of the baryon asymmetry of the universe remains one of the most pressing open questions in particle physics and cosmology. Electroweak baryogenesis offers an experimenta…
Gravitational Wave Production During Reheating: From the Inflaton to Primordial Black Holes
Mathieu Gross, Essodjolo Kpatcha, Yann Mambrini +2
We calculate the gravitational waves (GWs) produced by primordial black holes (PBHs) in the presence of the inflaton condensate in the early Universe. Combining the GW production f…
Searching for a new light gauge boson with axial couplings in muon beam dump experiments
Pierre Fayet, María Olalla Olea-Romacho
We present a formalism for new interactions involving weak hypercharge, baryon, and lepton numbers, and a possible axial symmetry generator in the presence of a second…
