Clues to the nature of dark matter from first galaxies
Boyan K. Stoychev, Keri L. Dixon, Andrea V. Macciò +2
We use thirty-eight high-resolution simulations of galaxy formation between redshift 10 and 5 to study the impact of a 3 keV warm dark matter (WDM) candidate on the high-redshift U…
Using Artificial Neural Networks to Constrain the Halo Baryon Fraction during Reionization
David Sullivan, Ilian T. Iliev, Keri L. Dixon
Radiative feedback from stars and galaxies has been proposed as a potential solution to many of the tensions with simplistic galaxy formation models based on CDM, such as the fa…
Bubble size statistics during reionization from 21-cm tomography
Sambit K. Giri, Garrelt Mellema, Keri L. Dixon +1
The upcoming SKA1-Low radio interferometer will be sensitive enough to produce tomographic imaging data of the redshifted 21-cm signal from the Epoch of Reionization. Due to the no…
A self-consistent 3D model of fluctuations in the helium-ionizing background
Frederick B. Davies, Steven R. Furlanetto, Keri L. Dixon
Large variations in the effective optical depth of the He II Ly forest have been observed at , but the physical nature of these variations is uncertain: either the…
The evolution of the helium-ionizing background at z ~ 2-3
Keri L. Dixon, Steven R. Furlanetto
Recent observations suggest that helium became fully ionized around redshift z ~ 3. The HeII optical depth derived from the Lyman-alpha forest decreases substantially from this per…
