We describe the goals, design, implementation, and initial progress of the UKIRT Infrared Deep Sky Survey (UKIDSS), a seven-year sky survey which began in 2005...
The UKIRT Infrared Deep Sky Survey Early Data Release
This paper defines the UKIRT Infrared Deep Sky Survey (UKIDSS) Early Data Release (EDR). UKIDSS is a set of five large near-infrared surveys being undertaken...
The ultracool helium-atmosphere white dwarf companion of PSR J0740+6620?
We report detection of the likely companion of the binary millisecond pulsar (MSP) J0740+6620 with the Gran Telescopio Canarias in the r' and i' bands. The...
The ultraluminous X-ray source NGC 1313 X-2. Its optical counterpart and environment
NGC 1313 X-2 is one of the brightest ultraluminous X-ray sources in the sky, at both X-ray and optical wavelengths; therefore, quite a few studies of available...
The ultraluminous X-ray sources in the high-velocity system of NGC1275
We report the results of a study of X-ray point sources coincident with the high-velocity system (HVS) projected in front of NGC1275. A very deep X-ray image of...
The ultraviolet luminosity function of star-forming galaxies between redshifts of 0.6 and 1.2
We use ultraviolet (UV) imaging taken with the XMM-Newton Optical Monitor telescope (XMM-OM), covering 280 arcmin 2 in the UVW1 band (λ eff = 2910 Å) to measure...
The Ultraviolet Spectrum and Physical Properties of the Mass Donor Star in HD 226868 = Cygnus X-1
We present an examination of high-resolution, ultraviolet (UV) spectroscopy from Hubble Space Telescope of the photospheric spectrum of the O-supergiant in the...
A Copernicus spectrum of the early-type supergiant Beta Ori, extending from 1010 to 1440 A with 0.2-A resolution and from 1710 to 3215 A with 0.4-A resolution...
The ultraviolet to far-infrared spectral energy distribution of star-forming galaxies in the redshift desert
We analyse the rest-frame ultraviolet (UV) to near-infrared (near-IR) spectral energy distribution (SED) of Lyman-break galaxies (LBGs), star-forming (SF) BzK...
