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…
Running of the spectral index: Reconciling the CMB with the Lyman- Forest
Malcolm Fairbairn, Lucien Heurtier, María Olalla Olea-Romacho
We investigate the scale dependence of the primordial power spectrum by combining \Planck, ACT DR6, SPT-3G, and eBOSS Lyman- forest data, extending sensitivity to smaller comovi…
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…
