The Growth of the Earliest Supermassive Black Holes and Their Contribution to Reionization
Zoltan Haiman, Mark Dijkstra, Andrei Mesinger
We discuss currently available observational constraints on the reionization history of the intergalactic medium (IGM), and the extent to which accreting black holes (BHs) can help…
On Detecting the X-ray Silhouette of a Damped Lyman alpha System
Mark Dijkstra, Zoltan Haiman, Caleb Scharf
We explore the possibility of resolving an image of a damped Lyman alpha (DLA) system in absorption against an extended, diffuse background X-ray source. Typical columns of neutral…
A Limit from the X-ray Background on the Contribution of Quasars to Reionization
Mark Dijkstra, Zoltan Haiman, Abraham Loeb
A population of black holes (BHs) at high redshifts (z>6) that contributes significantly to the ionization of the intergalactic medium (IGM) would be accompanied by the copious pro…
