Investigating ULIRGs in the Near-Infrared: Imaging & Spectroscopy

R. Davies, A. Burston, M. Ward

We present imaging and spectroscopic observations of 2 nearby (z<0.1) ULIRGs from a larger sample, and address the question of whether the JHK continuum colours and slope might be…

The non-stellar infrared continuum of Seyfert galaxies

A. Alonso-Herrero, A. C. Quillen, C. Simpson +2

JHKL'M (1-5 micron) imaging of a sample of Seyfert (Sy) 2 galaxies is presented. We confirm that the 1-2.2 micron nuclear continuum of some Sy 2s is dominated by stellar emission,…

1-5 micron imaging of 3CRR galaxies: The K-z relation and the geometry of the torus

Chris Simpson, Martin Ward, J. V. Wall

It has been claimed by Taylor et al. that the low-redshift end of the K-z relation for radio galaxies is too bright by about half a magnitude due to contributions from the obscured…

Studies of the high luminosity quasar, PDS 456

J. Reeves, P. O'Brien, S. Vaughan +5

X-ray and multi-wavelength observations of the most luminous known local (z<0.3) AGN, the recently discovered radio-quiet quasar PDS 456, are presented. The spectral energy distrib…

Extended Gas in Seyfert Galaxies: Near-Infrared Observations of 15 Active Nuclei

Claudia Winge, Thaisa Storchi-Bergmann, Martin J. Ward +1

Results from an analysis of low resolution (R~250) near-IR long-slit spectra covering simultaneously the I, J, H, and K bands, for a sample of 15 Seyfert galaxies and the N5253 sta…
