A Burst of Reionization in the Dark Ages
Neal Weiner, Soubhik Kumar, Wenzer Qin +3
Primordial overdensities at small scales can be significantly larger than those observed at large scales. As a result, they can collapse much earlier, at redshifts . In…
Chaotic migration of LISA Extreme Mass Ratio Inspirals in a turbulent accretion disk: effect on waveform de-phasing
Mudit Garg, Lucio Mayer, Yinhao Wu +2
Gravitational wave (GW) detector LISA will observe near-coalescence extreme mass ratio inspirals (EMRIs), which typically form in galactic central accretion disks. Torques from the…
What it takes to solve the Hubble tension through scale-dependent modifications of the primordial power spectrum
Nanoom Lee, Matteo Braglia, Yacine Ali-Haïmoud
We investigate scale-dependent modifications to the primordial scalar power spectrum as potential solutions to the Hubble tension. We use the Fisher-bias formalism, recently adapte…
CMB polarization non-Gaussianity from accreting primordial black holes
Trey W. Jensen, Yacine Ali-Haïmoud
Primordial black holes (PBHs) would induce non-Gaussianity in the cosmic microwave background (CMB) by sourcing recombination perturbations spatially modulated by relative velociti…
Magnetic fields from small-scale primordial perturbations
Nanoom Lee, Yacine Ali-Haimoud
Weak magnetic fields must have existed in the early Universe, as they were sourced by the cross product of electron density and temperature gradients through the Biermann-battery m…
Cosmic Recombination in the Presence of Primordial Magnetic Fields
Karsten Jedamzik, Tom Abel, Yacine Ali-Haimoud
Primordial magnetic fields (PMFs) may explain observations of magnetic fields on extragalactic scales. They are most cleanly constrained by measurements of cosmic microwave backgro…
