Reionization, UV Luminosity and 21cm Sensitivity to Primordial Magnetic Fields: Impact of Energy Losses
Gaétan Facchinetti, Alexander Korochkin, Laura Lopez-Honorez +1
Magnetic fields with field strengths between G and a few Nanogauss are expected to exist today in the intergalactic medium (IGM). Their origin is unknown, but may be of…

21 cm Cosmology Sensitivity to Small-Scale Structure: Warm vs Neutrino-Interacting Dark Matter
Virgile Dandoy, Christian Döring, Gaétan Facchinetti +2
The cm signal originating from Cosmic Dawn to the Epoch of Reionisation is highly sensitive to the processes governing star formation in the early universe as well as new phy…
