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…
Non-Cold Dark Matter from Memory-Burdened Primordial Black Holes
Valentin Thoss, Laura Lopez-Honorez, Florian Kühnel +1
Non-cold dark matter particles can arise from the evaporation of primordial black holes (PBHs). In this paper, we further investigate how the memory-burden effect, which delays the…
Minimal Dark Matter: Generalized Framework and Direct-Detection Sensitivity
Spencer Griffith, Juri Smirnov, Laura Lopez-Honorez +1
Minimal electroweak dark matter models are compelling due to their simplicity, though calculations of their freezeout abundance are complicated by nonperturbative effects due to So…
Constraining long-lived dark sector particles with CMB and Lyman-
Laura Lopez-Honorez, Sonali Verma
We use measurements of the intergalactic medium (IGM) temperature from the Lyman- forest to place new limits on models in which long-lived dark sector (DS) particles, with life…
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…
t-channel dark matter at the LHC -- a whitepaper
Chiara Arina, Benjamin Fuks, Luca Panizzi +67
This report, summarising work achieved in the context of the LHC Dark Matter Working Group, investigates the phenomenology of -channel dark matter models, spanning minimal setup…
