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…
Evidence of patchy hydrogen reionization from an extreme Ly trough below redshift six
George D. Becker, James S. Bolton, Piero Madau +3
We report the discovery of an extremely long (110 Mpc/) and dark () Ly trough extending down to towards the $z_{\rm em} \simeq 6.0…
The Photon Underproduction Crisis
Juna A. Kollmeier, David H. Weinberg, Benjamin D. Oppenheimer +9
We examine the statistics of the low-redshift Lyman-alpha forest from smoothed particle hydrodynamic simulations in light of recent improvements in the estimated evolution of the c…
Super-Critical Growth of Massive Black Holes from Stellar-Mass Seeds
Piero Madau, Francesco Haardt, Massimo Dotti
We consider super-critical accretion with angular momentum onto stellar-mass black holes as a possible mechanism for growing billion-solar-mass holes from light seeds at early time…
Cosmic Star Formation History
Piero Madau, Mark Dickinson
Over the past two decades, an avalanche of data from multiwavelength imaging and spectroscopic surveys has revolutionized our view of galaxy formation and evolution. Here we review…
A cosmic web filament revealed in Lyman-alpha emission around a luminous high-redshift quasar
Sebastiano Cantalupo, Fabrizio Arrigoni-Battaia, J. Xavier Prochaska +2
Simulations of structure formation in the Universe predict that galaxies are embedded in a "cosmic web", where the majority of baryons reside as rarefied and highly ionized gas. Th…
