Deep near-infrared spectroscopy of submillimetre-selected galaxies (2004)
Journal Article
Simpson, C., Dunlop, J., Eales, S., Ivison, R., Scott, S., Lilly, S., & Webb, T. (2004). Deep near-infrared spectroscopy of submillimetre-selected galaxies. Monthly Notices of the Royal Astronomical Society, 353(1), 179-188. https://doi.org/10.1111/j.1365-2966.2004.08054.x

We present the results of deep near-infrared spectroscopy of seven submillimetre-selected galaxies from the Submillimetre Common User Bolometer Array (SCUBA) 8-mJy Survey and Canada–UK Deep Submillimetre Survey (CUDSS). These galaxies were selected b... Read More about Deep near-infrared spectroscopy of submillimetre-selected galaxies.

Dust and Gas Obscuration in ELAIS Deep X-Ray Survey Reddened Quasars (2004)
Journal Article
Willott, C. J., Simpson, C., Almaini, O., Johnson, O., Lawrence, A., Dunlop, J. S., …Rowan-Robinson, M. (2004). Dust and Gas Obscuration in ELAIS Deep X-Ray Survey Reddened Quasars. Astrophysical Journal, 610(1), 140-150. https://doi.org/10.1086/421385

Hard X-ray surveys have uncovered a large population of heavily obscured AGNs. They also reveal a population of quasars with moderate obscuration at both visible and X-ray wavelengths. We use Chandra-selected samples of quasars from the ELAIS Deep X-... Read More about Dust and Gas Obscuration in ELAIS Deep X-Ray Survey Reddened Quasars.

The radio galaxy 3C 356 and clues to the trigger mechanisms for powerful radio sources (2002)
Journal Article
Simpson, C., & Rawlings, S. (2002). The radio galaxy 3C 356 and clues to the trigger mechanisms for powerful radio sources. Monthly Notices of the Royal Astronomical Society, 334(3), 511-522. https://doi.org/10.1046/j.1365-8711.2002.05453.x

We present deep near-infrared images, taken with the Subaru Telescope, of the region around the z=1.08 radio source 3C 356 which show it to be associated with a poor cluster of galaxies. We discuss evidence that this cluster comprises two subclusters... Read More about The radio galaxy 3C 356 and clues to the trigger mechanisms for powerful radio sources.

The Optical Counterpart of the Accreting Millisecond Pulsar SAX J1808.4-3658 in Outburst: Constraints on the Binary Inclination (2001)
Journal Article
Wang, Z., Chakrabarty, D., Roche, P., Charles, P. A., Kuulkers, E., Shahbaz, T., …Helsdon, S. F. (2001). The Optical Counterpart of the Accreting Millisecond Pulsar SAX J1808.4-3658 in Outburst: Constraints on the Binary Inclination. Astrophysical Journal Letters, 563(1), L61-L64. https://doi.org/10.1086/338357

We present multiband optical/IR photometry of V4580 Sgr, the optical counterpart of the accretion-powered millisecond pulsar SAX J1808.4-3658, taken during the 1998 X-ray outburst of the system. The optical flux is consistent with emission from an X-...
