Using SCUBA to place upper limits on arcsecond scale CMB anisotropies at 850 microns
(1999-09-19)
The SCUBA instrument on the James Clerk Maxwell Telescope has already had an impact on cosmology by detecting relatively large numbers of dusty galaxies at high redshift. Apart from identifying well-detected sources, such ...
First detections of FIRBACK sources with SCUBA
(1999-10-22)
The FIRBACK (Far InfraRed BACKground) survey represents the deepest extensive 170 micron images obtained by the ISO satellite. The sources detected comprise about 10% of the Cosmic IR Background (CIB) seen by COBE, and, ...
Submillimeter Observations of the Ultraluminous BAL Quasar APM 08279+5255
(1998-9-20)
With an inferred bolometric luminosity of $5\times10^{15}{\rm \lsun}$, the recently identified z=3.87, broad absorption line quasar APM 08279+5255 is apparently the most luminous object currently known. As half of its ...
First results from the UBC etch-alignment mosaic CCD
(1997-06-26)
First imaging results are obtained with a new CCD mosaic prototype (3K x 3k, 15 \mu m pixels). The CCDs are aligned using an etched socket alignment technique. Three different measurements of the alignment are made using ...
B1933+503, a dusty radio quasar at z>2: implications for blank field sub-mm surveys?
(1998-10-27)
We present a detailed mm-wave and optical study of the gravitational lens system B1933+503, discovered by Sykes et al.(1998) in the radio. This object is probably the most complex lens system known, with 10 lensed components ...
