Lyman-alpha emitters gone missing: evidence for late reionization?
Tirthankar Roy Choudhury, Ewald Puchwein, Martin G. Haehnelt +1
We combine high resolution hydrodynamical simulations with an intermediate resolution, dark matter only simulation and an analytical model for the growth of ionized regions to esti…
The Lyman-alpha forest in f(R) modified gravity
Christian Arnold, Ewald Puchwein, Volker Springel
In this work, we analyze the Lyman- forest in cosmological hydrodynamical simulations of chameleon-type f(R) gravity with the goal to assess whether the impact of such models is…
The photoheating of the intergalactic medium in synthesis models of the UV background
Ewald Puchwein, James S. Bolton, Martin G. Haehnelt +3
We compare cosmological hydrodynamical simulations combined with the homogeneous metagalactic UV background (UVB) of Haardt & Madau (2012) (HM2012) to observations of the Lyman-alp…
Nonlinear growing neutrino cosmology
Youness Ayaita, Marco Baldi, Florian Führer +2
The energy scale of Dark Energy, eV, is a long way off compared to all known fundamental scales - except for the neutrino masses. If Dark Energy is dynamica…
