The soft X-ray properties of quasars in the Sloan Digital Sky Survey

Shiyin Shen, Simon D. M. White, H. J. Mo +4

We use the ROSAT All Sky Survey (RASS) to study the soft X-ray properties of a homogeneous sample of 46,420 quasars selected from the third data release of the Sloan Digital Sky Su…

An excursion set model of the cosmic web: The abundance of sheets, filaments and halos

Jiajian Shen, Tom Abel, H. J. Mo +1

We discuss an analytic approach for modeling structure formation in sheets, filaments and knots. This is accomplished by combining models of triaxial collapse with the excursion se…

On The Assembly History of Dark Matter Haloes

Yun Li, H. J. Mo, Frank C. van den Bosch +1

(abridged) We study the mass assembly history (MAH) of dark matter haloes. We compare MAHs obtained using (i) merger trees constructed with the extended Press-Schechter (EPS) forma…

Properties of Galaxy Groups in the SDSS: I.-- The Dependence of Colour, Star Formation, and Morphology on Halo Mass

Simone M. Weinmann, Frank C. van den Bosch, Xiaohu Yang +1

Using a large galaxy group catalogue constructed from the SDSS, we investigate the correlation between various galaxy properties and halo mass. We split the population of galaxies…

Observational Evidence for an Age Dependence of Halo Bias

Xiaohu Yang, H. J. Mo, Frank C. van den Bosch

We study the dependence of the cross-correlation between galaxies and galaxy groups on group properties. Confirming previous results, we find that the correlation strength is stron…

On the origin of cold dark matter halo density profiles

Yu Lu, H. J. Mo, Neal Katz +1

N-body simulations predict that CDM halo-assembly occurs in two phases: 1) a fast accretion phase with a rapidly deepening potential well; and 2) a slow accretion phase characteris…
