PAH emission variations within the resolved starbursts of NGC253 and NGC1808

L. E. Tacconi-Garman, E. Sturm, M. Lehnert +3

(ABRIDGED) We have undertaken a programme of 3 micron narrowband imaging of a sample of nearby template galaxies covering a wide range of metallicity, star formation activity, and…

The unusual morphology of the intragroup medium in NGC 5171

John P. F. Osmond, Trevor J. Ponman, Alexis Finoguenov

We present the results of a 24 ks XMM-Newton observation of the NGC 5171 group of galaxies. NGC 5171 is unusual in that it is an X-ray bright group (L > 10^42 erg/s), with irregula…

Long term variability of Cygnus X-1, III. Radio-X-ray correlations

T. Gleissner, J. Wilms, G. G. Pooley +7

Long time scale radio-X-ray correlations in black holes during the hard state have been found in many sources and there seems to emerge a universal underlying relationship which qu…

Spectral constraints on unidentified EGRET gamma-ray sources from COMPTEL MeV observations

S. Zhang, W. Collmar, W. Hermsen +1

We investigated the MeV properties of 173 unidentified or only tentatively identified EGRET sources listed in the third EGRET catalogue, by analyzing the simultaneously collected C…

A 1200 micron MAMBO Survey of ELAIS N2 and the Lockman Hole: I. Maps, sources and number counts

T. R. Greve, R. J. Ivison, F. Bertoldi +4

We present a deep, new 1200 micron survey of the ELAIS N2 and Lockman Hole fields using the Max Planck Millimeter Bolometer array (MAMBO). The areas surveyed are 160 arcmin^2 in EL…

Ks-band luminosity function of the z=1.237 cluster of galaxies RDCS J1252.9-2927

S. Toft, V. Mainieri, P. Rosati +4

We derive the Ks-band luminosity function (LF) of the z=1.237 massive X-ray luminous cluster of galaxies RDCS J1252.9-2927. Photometric redshifts, derived from deep multi-wavelengt…
