A new gravitational lens from the MUSCLES survey: ULAS J082016.1+081216 (2009)
Jackson, Neal, Ofek, Eran O., Oguri, Masamune
We present observations of a new double-image gravitational lens system, ULAS J082016.1+081216, of image separation 2.3" and high (~6) flux ratio. The system is selected from the Sloan Digital Sky...

Jackson, Neal, Ofek, Eran O., Oguri, Masamune
We present observations of a new double-image gravitational lens system, ULAS J082016.1+081216, of image separation 2.3 arcsec and high (∼6) flux ratio. The system is selected from the Sloan...
Gravitational lenses and lens candidates identified from the COSMOS field (2008)
A complete manual search has been carried out of the list of 285423 objects, nearly all of them galaxies, identified in the COSMOS field that are brighter than I=25. Two certain and one highly...
ULAS J234311.93-005034.0: A gravitational lens system selected from UKIDSS and SDSS (2008)
Jackson, Neal, Ofek, Eran O., Oguri, Masamune
We report the discovery of a new gravitational lens system. This object, ULAS J234311.93-005034.0, is the first to be selected by using the new UKIRT Infrared Deep Sky Survey (UKIDSS), together with...

We report the discovery of a new gravitationally lensed quasar, SDSS J131339.98+515128.3, at a redshift of 1.875 with an image separation of 1.24 arcsec. The lensing galaxy is clearly detected in...
I review the current state of determinations of the Hubble constant, which gives the length scale of the Universe by relating the expansion velocity of objects to their distance. In the last 20...

Near-infrared spectroscopy of powerful compact steep-spectrum radio sources (2003)
Hirst, Paul, Jackson, Neal, Rawlings, Steve
We have obtained near-infrared spectroscopy of a small sample of powerful Compact Steep-Spectrum (CSS) radio sources mainly, but not exclusively, from the 3CR sample. We find no differences between...
