  • Herbert, Peter; Jarvis, Matthew John; Willcott, C.J.; McLure, R.J.; Mitchell, E.; Rawlings, S.; Hill, G.J.; Dunlop, J.S. (2011)
    We present deep spectroscopic data for a 24-object subsample of our full 41-object z∼ 0.5 radio galaxy sample in order to investigate the evolution of the Fundamental Plane of radio galaxies. We find that the low-luminosity, ...
  • Ruhland, Christine; Bell, Eric F.; Haeussler, Boris; Taylor, Edward N.; Barden, Marco; McIntosh, Daniel H. (2009-04-20)
    We present first measurements of the evolution of the scatter of the cosmic average early-type galaxy color-magnitude relation (CMR) from z = 1 to the present day, finding that it is consistent with models in which galaxies ...
  • Casewell, Sarah L.; Burleigh, Matt R.; Dobbie, Paul D.; Napiwotzki, Ralf (American Institute of Physics, 2011)
    We have obtained near-IR photometry for the 11 Praesepe white dwarfs, to search for an excess indicative of a dusty debris disk. All the white dwarfs are in the DAZ temperature regime, however we find no indications of a ...

    We present submillimetre and mid-infrared imaging observations of five fields centred on quasi-stellar objects (QSOs) at 1.7 < z < 2.8. All 5 QSOs were detected previously at submillimetre wavelengths. At 850 (450) μm we ...

    The 58Ni(n,γ) cross section has been measured at the neutron time of flight facility n-TOF at CERN, in the energy range from 27 meV up to 400 keV. In total, 51 resonances have been analyzed up to 122 keV. Maxwellian averaged ...
  • Dillmann, I.; Heil, M.; Kappeler, F.; Rauscher, T.; Thielemann, Friedrich-Karl (2006-01)
    The nucleosynthesis of elements beyond iron is dominated by the s and r processes. However, a small amount of stable isotopes on the proton-rich side cannot be made by neutron capture and are thought to be produced by ...
  • Mohr, P.; Vogt, K.; Babilon, M.; Enders, J.; Hartmann, T.; Hutter, C.; Rauscher, T.; Volz, S.; Zilges, A. (2000-08-31)
