      Grandi, P.; Urry, C.M.; Maraschi, L.; Wehrle, A. E.; Madejski, G. M.; Aller, M. F.; Aller, H. D.; Bailyn, C. D.; Balonek, T.J.; Bock, T. H.; Glass, I. S.; Litchfield, S.J.; McHardy, I.M.; Mulchaey, J. S.; Reuter, H.-P.; Robson, E. I.; Sadun, A. C.; Sherry, W.; Steppe, H.; Stevens, Jason; Teraesranta, H.; Tornikoski, M.; Wagner, S.J. (1996-03-01)
      The optically violently variable quasar 3C 279 was monitored simultaneously from radio to y-ray frequencies in 1992 December-1993 January. We report a detailed study of the ground-based results from radio to optical ...

    • A Gamma-Ray Flare in NRAO 190 

      McGlynn, T. A.; Hartman, R. C.; Bloom, S. D.; Aller, M.; Aller, H.; Filippenko, A. V.; Barth, A. J.; Gear, W. K.; Marscher, A. P.; Mattox, J. R.; Reich, W.; Robson, E. I.; Schramm, J.; Stevens, Jason; Teraesranta, H.; Tornikoski, M.; Vestrand, W. T.; Wagner, S.; Heines, A. (1997-05-01)
      We describe observations of the quasi-stellar object (QSO) NRAO 190 during a gamma-ray flare from 1994 August 9 to 1994 August 29. This QSO was serendipitously detected by the EGRET instrument on the Compton Gamma Ray ...

    • Imaging the environment of A z = 6.3 submillimeter galaxy with scuba-2 

      Robson, E. I.; Ivison, R. J.; Smail, Ian; Holland, W. S.; Geach, J. E.; Gibb, A. G.; Riechers, D.; Ade, P. A R; Bintley, D.; Bock, J.; Chapin, E. L.; Chapman, S. C.; Clements, D. L.; Conley, A.; Cooray, A.; Dunlop, J. S.; Farrah, D.; Fich, M.; Fu, Hai; Jenness, T.; Laporte, N.; Oliver, S. J.; Omont, A.; Pérez-Fournon, I.; Scott, Douglas; Swinbank, A. M.; Wardlow, J. (2014-08-28)
      We describe a search for submillimeter emission in the vicinity of one of the most distant, luminous galaxies known, HerMES FLS3, at z = 6.34, exploiting it as a signpost to a potentially biased region of the early universe, ...

    • Millimeter and Submillimeter Polarization Observations of Blazars 

      Stevens, Jason; Robson, E. I.; Holland, W. S. (1996-05-01)
      Millimeter and submillimeter polarization observations of blazars from the James Clerk Maxwell Telescope are presented. The data are interpreted in light of recent results from centimeter wavelength VLBI polarimetry studies. ...

P.; Valiante, E.; Webb, T. M. A.; Willott, C.; Zavala, J. A.; Zemcov, M. (2016-11-10)
      We present a catalogue of nearly 3,000 submillimetre sources detected at 850um over ~5 square degrees surveyed as part of the James Clerk Maxwell Telescope (JCMT) SCUBA-2 Cosmology Legacy Survey (S2CLS). This is the largest ...

    • The SCUBA-2 Cosmology Legacy Survey : The EGS deep field I - Deep number counts and the redshift distribution of the recovered Cosmic Infrared Background at 450 and 850 um

      We present deep observations at 450 um and 850 um in the Extended Groth Strip field taken with the SCUBA-2 camera mounted on the James Clerk Maxwell Telescope as part of the deep SCUBA-2 Cosmology Legacy Survey (S2CLS), ...

    • The Spectral Evolution of High-Frequency Radio Outbursts in the Blazar PKS:0420-014 

      Stevens, Jason; Litchfield, S. J.; Robson, E. I.; Gear, W. K.; Terasranta, H.; Tornikoski, M.; Valtaoja, E. (1995-08-01)
      Multifrequency monitoring data between 375 and 22 GHz are used to investigate spectral evolution of radio outbursts in the blazar 0420-014. It is shown that, after subtraction of the underlying `quiescent' emission, the ...
