Excursion set peaks in energy as a model for haloes

TL;DR: In this paper, it was shown that these configurations are minima of the total energy, i.e. the most energetically bound spheres, and the model is richer in the sense that it naturally predicts scatter in the overdensities of protohalo patches that are destined to form halos of the same mass, in qualitative agreement with simulations of halo formation.

Halo abundances and counts-in-cells: The excursion set approach with correlated steps

TL;DR: In this paper, Peacock and Heavens presented a simple approximation for the first crossing distribution of a single barrier of constant height by walks with correlated steps, which can be thought of as a correction to the distribution associated with what are smooth completely correlated walks.
Journal ArticleDOI

Environment and the cosmic evolution of star formation

TL;DR: In this article, the authors present a mark correlation analysis of the galaxies in the Sloan Digital Sky Survey using weights provided by MOPED, and find that those galaxies which dominated the cosmic star formation at z~3 are predominantly in clusters today, whereas galaxies which dominate the star formation in z~0 inhabit substantially lower mass objects in less dense regions today.

Radial Acceleration Relation by Dark Matter and Baryons in the Intermediate Acceleration Regime

TL;DR: In this article, the relation between radial acceleration due to the baryonic mass distribution and the dark (or phantom) matter distribution in the intermediate acceleration range was investigated and the results constrain theories of dark matter or modified gravity.
Journal ArticleDOI

Satellite Luminosities in Galaxy Groups

TL;DR: In this article, the authors make the remarkable prediction that the mean luminosity of the non-central galaxies in a halo should be almost independent of halo mass: the predicted increase is about 20% while the Halo mass increases by a factor of more than 20.
