The Fundamental Scaling Relations of Elliptical Galaxies

B. Robertson, T. J. Cox, L. Hernquist +4

(ABRIDGED) We examine the fundamental scaling relations of elliptical galaxies formed through mergers. Using hundreds of simulations to judge the impact of progenitor galaxy proper…

Lyman-alpha forest-CMB cross-correlation and the search for the ionized baryons at high redshift

Rupert A. C. Croft, A. J. Banday, Lars Hernquist

The intergalactic neutral hydrogen which is responsible for the Lyman alpha forest of quasar absorption is a tracer of much larger amounts of ionised hydrogen. The ionised componen…

Cosmological Parameter Estimation Using 21 cm Radiation from the Epoch of Reionization

Matthew McQuinn, Oliver Zahn, Matias Zaldarriaga +2

A number of radio interferometers are currently being planned or constructed to observe 21 cm emission from reionization. Not only will such measurements provide a detailed view of…

Distribution of Damped Lyman-alpha Absorbers in a Lambda Cold Dark Matter Universe

Kentaro Nagamine, Arthur M. Wolfe, Lars Hernquist +1

We present the results of a numerical study of a galactic wind model and its implications on the properties of damped Lyman-alpha absorbers (DLAs) using cosmological hydrodynamic s…

How Much Mass do Supermassive Black Holes Eat in their Old Age?

Philip F. Hopkins, Ramesh Narayan, Lars Hernquist

We consider the distribution of local supermassive black hole Eddington ratios and accretion rates, accounting for the dependence of radiative efficiency and bolometric corrections…

The Evolution in the Faint-End Slope of the Quasar Luminosity Function

Philip F. Hopkins, Lars Hernquist, Thomas J. Cox +3

(Abridged) Based on numerical simulations of galaxy mergers that incorporate black hole (BH) growth, we predict the faint end slope of the quasar luminosity function (QLF) and its…
