TL;DR: Conley et al. as discussed by the authors used color information to verify the acceleration of the universe using a blind analysis of Type Ia supernovae with CMAGIC, which has several advantages over current techniques based on maximum magnitudes.

TL;DR: In this paper, a new measurement of the volumetric rate of SNe Ia up to a redshift of 1.7 was presented, using the HST GOODS data combined with an additional HST data set covering the GOODS-North field collected in 2004.
Journal ArticleDOI
The light curve of the companion to PSR B1957+20
TL;DR: In this paper, the authors present a new analysis of the secondary star in the eclipsing binary millisecond pulsar system PSR B1957+20, which combines previous data and new data points at minimum from the Hubble Space Telescope, they have 100 per cent coverage in the R-band.
