We use the largest complete sample of 64 galaxy clusters (HIghest X-ray FLUx Galaxy Cluster Sample) with available high-quality X-ray data from Chandra, and apply 16 cool-core diagnostics to them,…
Four Extreme Relic Radio Sources in Clusters of Galaxies
- O. Slee, A. Roy, M. Murgia, H. Andernach, M. Ehle
- Physics
- 16 May 2001
We describe the results of the highest-resolution radio observations yet made of four relic radio sources in the Abell clusters A13, A85, A133, and A4038. Our Very Large Array images at 1.4 GHz with…
The Karl G. Jansky Very Large Array Sky Survey (VLASS). Science Case and Survey Design
The science case and observational strategy for the Very Large Array Sky Survey is presented, and also results from early survey observations are presented.

Abstract EMU is a wide-field radio continuum survey planned for the new Australian Square Kilometre Array Pathfinder (ASKAP) telescope. The primary goal of EMU is to make a deep (rms ∼ 10 μJy/beam)…
Extragalactic database. VII. Reduction of astrophysical parameters
- G. Paturel, H. Andernach, I. Vauglin
- Physics
- 1 July 1997
The Lyon-Meudon Extragalactic database (LEDA) gives a free access to the main astrophysical parameters for more than 100 000 galaxies. The most common names are compiled allowing users to recover…
Optical and X-Ray Clusters as Tracers of the Supercluster-Void Network. I. Superclusters of Abell and X-Ray Clusters
- M. Einasto, J. Einasto, E. Tago, V. Müller, H. Andernach
- Physics
- 29 December 2000
We study the distribution of Abell and X-ray–selected clusters of galaxies and derive selection functions of these cluster samples. We find that selection functions and percolation properties of…
A 120-Mpc periodicity in the three-dimensional distribution of galaxy superclusters
- J. Einasto, M. Einasto, P. Frisch
- PhysicsNature
- 6 January 1997
ACCORDING to the favoured models for the formation of large-scale structure in the Universe (in which the dynamics of the Universe is dominated by cold dark matter), the distribution of galaxies and…
THE DYNAMICAL STATE OF BRIGHTEST CLUSTER GALAXIES AND THE FORMATION OF CLUSTERS
- R. Coziol, H. Andernach, C. Caretta, K. Alamo-Martínez, E. Tago
- Physics
- 13 March 2009
A large sample of Abell clusters of galaxies, selected for the likely presence of a dominant galaxy, is used to study the dynamical properties of the brightest cluster members (BCMs). From visual…
The supercluster–void network - I. The supercluster catalogue and large-scale distribution
- M. Einasto, E. Tago, J. Jaaniste, J. Einasto, H. Andernach
- Physics
- 12 October 1996
We investigate the distribution of superclusters and voids using a new catalogue of superclusters of rich clusters of galaxies which extends up to a redshift of . The new catalogue contains 220…
