Starbursts in ultraluminous infrared galaxies - fueling and properties
Paul P. van der Werf
The properties of starbursts in ultraluminous infrared galaxies are discussed, with particular emphasis on the fueling, the amount of extinction and the intrinsic properties of the…
Lessons from lensed Lyman break galaxies: can dusty Lyman break galaxies produce the submillimetre counts and background?
Paul P. van der Werf, Kirsten Kraiberg Knudsen, Ivo Labb'e +1
Can the submillimetre counts and background be produced by applying a locally derived extinction correction to the population of Lyman break galaxies? We investigate the submillime…
The Elusive Active Nucleus of NGC 4945
A. Marconi, E. Oliva, P. P. van der Werf +4
We present new HST NICMOS observations of NGC 4945, a starburst galaxy hosting a highly obscured active nucleus that is one of the brightest extragalactic sources at 100 keV. The H…
NIR Spectroscopy with the VLT of a sample of ISO selected Hubble Deep Field South Galaxies
D. Rigopoulou, A. Franceschini, R. Genzel +6
A new population of faint galaxies characterized by an extremely high rate of evolution with redshift up to z~1.5 has recently been discovered by ISO. These sources are likely to c…
Submillimetre maps of the edge-on galaxy NGC 891
F. P. Israel, P. P. van der Werf, R. P. J. Tilanus
Broadband continuum images of the edge-on galaxy NGC 891 at 850 and 450 microns are presented. These images are qualitatively very similar to the 1300 micron and CO images obtained…
The obscured circumnuclear region of NGC 3079
F. P. Israel, P. P. van der Werf, T. G. Hawarden +1
Images in the J, H and K bands and in the the v=1-0 S(1) line of H2 of the central region of the almost edge-on galaxy NGC 3079 reveal contributions from direct and scattered starl…
