Journal ArticleDOI
The effects of velocities and lensing on moments of the Hubble diagram
Edward Macaulay,Tamara M. Davis,D. Scovacricchi,David Bacon,Thomas E. Collett,Robert C. Nichol +5 more
TL;DR: In this article, the dispersion on the supernova distance-redshift relation due to peculiar velocities and gravitational lensing, and the sensitivity of these effects to the amplitude of the matter power spectrum were considered.

Timothy A. McKay,Erin S. Sheldon,Judith Racusin,Philippe Fischer,Uroš Seljak,Albert Stebbins,David Johnston,Joshua A. Frieman,Neta A. Bahcall,J. Brinkmann,István Csabai,Masataka Fukugita,Gregory S. Hennessy,Zeljko Ivezic,D. Q. Lamb,Jon Loveday,Robert H. Lupton,Jeffrey A. Munn,Robert C. Nichol,Jeffrey R. Pier,Donald G. York +20 more
TL;DR: In this article, the authors present new measurements of scaling laws relating the luminosity of galaxies to the amplitude and shape of their dark matter halos, and test the universality of these mass-to-light scalings by independently measuring them for spiral and elliptical galaxies, and for galaxies in a variety of environments.

TL;DR: In this paper, the first spectroscopically confirmed hydrogen-free superluminous supernova (SLSN-I) at redshift z = 2.06 was discovered by the Dark Energy Survey (DES) Supernova Program, with followup photometric data from the Hubble Space Telescope, Gemini, and the European Southern Observatory Very Large Telescope supplementing the DES data.

TL;DR: In this article, a weak lensing mass map is reconstructed from shear measurements in a 139sq. deg area from the DES Science Verification (SV) data, and the authors compare the distribution of mass with that of the foreground distribution of galaxies and clusters.
Journal ArticleDOI
Testing Emergent Gravity on Galaxy Cluster Scales
TL;DR: In this article, the authors used the X-ray surface brightness measurements of the Coma cluster and from 58 stacked galaxy clusters along with the weak lensing data to test the theory of emergent gravity.
