We review theories of dark matter (DM) beyond the collisionless paradigm, known as self-
interacting dark matter (SIDM), and their observable implications for astrophysical structure …

The total mass of a galaxy cluster is one of its most fundamental properties. Together with
the redshift, the mass links observation and theory, allowing us to use the cluster population …

The evolution of the large-scale distribution of matter is sensitive to a variety of fundamental
parameters that characterise the dark matter, dark energy, and other aspects of our …

Modern Cosmology, Second Edition, provides a detailed introduction to the field of
cosmology. Beginning with the smooth, homogeneous universe described by a Friedmann …

Recent cosmological observations suggest the existence of a positive cosmological constant
Λ with the magnitude Λ (Gℏ/c3)≈ 10− 123. This review discusses several aspects of the …

We have developed a technique to systematically discover and study high-redshift
supernovae that can be used to measure the cosmological parameters. We report here …

Studies of galaxy clusters have proved crucial in helping to establish the standard model of
cosmology, with a Universe dominated by dark matter and dark energy. A theoretical basis …

We measure spectral indexes for 1823 galaxies in the Canadian Network for Observational
Cosmology 1 (CNOC1) sample of 15 X-ray luminous clusters at 0.18< z< 0.55 to investigate …

We measure the baryons contained in both the stellar and hot-gas components for 12 galaxy
clusters and groups at z∼ 0.1 with M= 1–5× 10 14 M☉. This paper improves upon our …

We examine the origin of clustercentric gradients in the star formation rates and colors of rich
cluster galaxies within the context of a simple model where clusters are built through the …
