The near-IR luminosity-metallicity relationship for dwarf irregular galaxies
Ivo Saviane, R. Riegerbauer, E. V. Held +6
We briefly describe our on-going investigation of the near-IR luminosity-metallicity relationship for dwarf irregular galaxies in nearby groups of galaxies. The motivations of the…

An XMM and Chandra view of massive clusters of galaxies to z=1
L. R. Jones, B. J. Maughan, H. Ebeling +7
The X-ray properties of a sample of high redshift (z>0.6), massive clusters observed with XMM-Newton and Chandra are described, including two exceptional systems. One, at z=0.89, h…

Multi-wavelength observations of serendipitous Chandra sources
P. Gandhi, C. S. Crawford, A. C. Fabian +4
We describe progress in a programme to study a sample of sources typical of those which contribute a large fraction of the hard X-ray background. The sources are selected from the…
