Simulating Wide-Field Quasar Surveys from the Optical to Near-Infrared
Natasha Maddox, Paul C. Hewett
A number of deep, wide-field, near-infrared surveys employing new infrared cameras on 4m-class telescopes are about to commence. These surveys have the potential to determine the f…
Selecting damped Lyman-alpha systems through CaII absorption. I: Dust depletions and reddening at z~1
Vivienne Wild, Paul Hewett, Max Pettini
We use the average E(B-V) and ZnII column densities of a sample of z~1 CaII (3935, 3970) absorption line systems selected from the Sloan Digital Sky Survey (SDSS DR4) to show that…
Classical novae from the POINT-AGAPE microlensing survey of M31 -- II. Rate and statistical characteristics of the nova population
M. J. Darnley, M. F. Bode, E. Kerins +17
We report the results of our statistical study of the POINT-AGAPE CNe catalogue. The first Sloan and analysis of the MMRD relationship in M31 is performed using the resul…
The discovery of two new galaxy-galaxy lenses from the SDSS
J. P. Willis, P. C. Hewett, S. J. Warren
The gravitational lens configuration where a background galaxy is closely aligned with a foreground galaxy, can provide accurate measurement of the dark matter density profile in t…
Distant Field BHB Stars III: Identification of a probable outer halo stream at Galactocentric distance r = 70 kpc
L. Clewley, S. J. Warren, P. C. Hewett +3
We present VLT-FORS1 spectra of a sample of 34 faint 20.0 < g* < 21.1 A-type stars selected from the Sloan Digital Sky Survey Early Data Release, with the goal of measuring the vel…
Evidence for dust reddening in DLAs identified through CaII H&K absorption
Vivienne Wild, Paul C. Hewett
We present a new sample of 31 CaII(H&K) 3935,3970 absorption line systems with 0.84<z_abs<1.3 discovered in the spectra of Sloan Digital Sky Survey (SDSS) Data Release 3 quasars, t…
