Journal ArticleDOI
A panoramic view of the Southern quadrant of the Andromeda galaxy outer halo
TL;DR: In this article, the authors present a panoramic view of the outer halo of the Milky Way and the Andromeda galaxy from a projected distance of ∼ 50 to ∼ 150 kpc.
Proceedings ArticleDOI

TL;DR: The calibration unit is described, which will be adapted from an existing unit for the AF2+WYFFOS spectrograph (WEAVE's precursor) at the WHT, and plans for upgrading the unit and its control systems to meet the WEAVE science and operational requirements are set out.
Journal ArticleDOI

TL;DR: A 2.5 × 100 degree region along the celestial equator (Stripe 82) has been imaged repeatedly from 1998 to 2005 by the Sloan Digital Sky Survey (SDSS) as discussed by the authors.

TL;DR: In this article, a supernova at z = 0.458 (SN1992bi) was discovered and its photometry closely matched the lightcurve calculated for its redshift from the template of well-observed nearby Type la supernovae giving a best fit value for the deceleration parameter: q o = 0 1 ± 0.3 (± 0.55) with Λ = 0, where the first uncertainty is due to the photometry of the distant supernova and the second reflects the estimated intrinsic width of the Type la absolute magnitude distribution based on nearby
