The Observed Growth of Massive Galaxy Clusters II: X-ray Scaling Relations

This is the second in a series of papers in which we derive simultaneous constraints on cosmology and X-ray scaling relations using observations of massive, X-ray fluxselected galaxy clusters. The data set consists of 238 clusters drawn from the ROSAT All-Sky Survey with 0.1–2.4 keV luminosities > 2.5×10h 70 erg s, and incorporates extensive follow-up observations using the Chandra X-ray Observ...

Adiabatic scaling relations of galaxy clusters

The aim of the present work is to show that, contrary to popular belief, galaxy clusters are not expected to be self-similar, even when the only energy sources available are gravity and shock-wave heating. In particular, we investigate the scaling relations between mass, luminosity and temperature of galaxy groups and clusters in the absence of radiative processes. Theoretical expectations are ...

Scaling relations in fossil galaxy groups

Using Chandra X-ray observations and optical imaging and spectroscopy of a flux-limited sample of 5 fossil groups, supplemented by additional systems from the literature, we provide the first detailed study of the scaling properties of fossils compared to normal groups and clusters. Fossil groups are dominated by a single giant elliptical galaxy at the centre of an extended bright X-ray halo. I...

Are Clusters Standard Candles? Galaxy Cluster Scaling Relations with the Sunyaev-zeldovich Effect

An extensive sample of galaxy clusters will be available in the coming years, detected through their Sunyaev–Zeldovich effect (SZE). We use a semi–analytic model to study the scientific yield of combining SZE data with X-ray and optical follow-up observations. If clusters at a given redshift zo can be identified with virialized, spherical halos, they populate a well–defined ”fundamental plane” ...

Galaxy Zoo: the environmental dependence of bars and bulges in disc galaxies

We present an analysis of the environmental dependence of bars and bulges in disc galaxies, using a volume-limited catalogue of 15 810 galaxies at z < 0.06 from the Sloan Digital Sky Survey with visual morphologies from the Galaxy Zoo 2 project. We find that the likelihood of having a bar, or bulge, in disc galaxies increases when the galaxies have redder (optical) colours and larger stellar ma...
