JHK photometry in the Mauna Kea Observatory (MKO) near-IR system is presented for 115 stars. Of these, 79 are UKIRT standards and 42 are LCO standards. The average brightness is 11.5 mag, with a range of 10 to 15. The average number of nights each st

We have secured long-slit spectra with R~440, covering the K, H and J bands, of 28, 26 and 13 nearby galaxies respectively. The target list comprises complete samples, flux-limited at 25 µm, of ‘normal’ (control) galaxies (undistorted morphology

Edison is a 1.7 m long-lived radiatively/mechanically-cooled space observatory proposed to operate over λ ∼ 3 – 100 + μ m using a suite of imaging and spectroscopic instruments. Thanks to innovative use of radiative cooling and very lightweight

For five years, the Edison program has had the goal of developing new designs for infrared space observatories which will “break the cost curve” by permitting more capable missions at lower cost. Most notably, this has produced a series of models

We present new small-beam submillimetre maps and multi-aperture photometry at three epochs and several wavelengths of the nearest giant radio galaxy, NGC 5128 (Centaurus A). The nucleus appears as an unresolved central source (FWHM < 6 arcsec at 800
