Discovery of a z=0.65 Post-Starburst BAL Quasar in the DES Supernova Fields

Kavli Affiliate: R. G. McMahon | First 5 Authors: Dale Mudd, Paul Martini, Suk Sien Tie, Chris Lidman, Richard McMahon | Summary: We present the discovery of a z=0.65 low-ionization broad absorption line (LoBAL) quasar in a post-starburst galaxy in data from the Dark Energy Survey (DES) and spectroscopy from the Australian Dark Energy Survey […]

Measurement of a Cosmographic Distance Ratio with Galaxy and CMB Lensing

Kavli Affiliate: Blake Sherwin | First 5 Authors: Hironao Miyatake, Mathew S. Madhavacheril, Neelima Sehgal, Anže Slosar, David N. Spergel | Summary: We measure the gravitational lensing shear signal around dark matter halos hosting CMASS galaxies using light sources at $zsim 1$ (background galaxies) and at the surface of last scattering at $zsim 1100$ (the […]

Bayesian Estimates of Astronomical Time Delays between Gravitationally Lensed Stochastic Light Curves

Kavli Affiliate: Kaisey Mandel | First 5 Authors: Hyungsuk Tak, Kaisey Mandel, David A. van Dyk, Vinay L. Kashyap, Xiao-Li Meng | Summary: The gravitational field of a galaxy can act as a lens and deflect the light emitted by a more distant object such as a quasar. Strong gravitational lensing causes multiple images of […]

Delensing Cosmic Microwave Background B-modes with the Square Kilometre Array Radio Continuum Survey

Kavli Affiliate: Blake Sherwin | First 5 Authors: Toshiya Namikawa, Daisuke Yamauchi, Blake Sherwin, Ryo Nagata, | Summary: We explore the potential use of the Radio Continuum (RC) survey conducted by the Square Kilometre Array (SKA) to remove (delens) the lensing-induced B-mode polarization and thus enhance future cosmic microwave background (CMB) searches for inflationary gravitational […]

SN~2012cg: Evidence for Interaction Between a Normal Type Ia Supernova and a Non-Degenerate Binary Companion

Kavli Affiliate: Kaisey Mandel | First 5 Authors: G. H. Marion, Peter J. Brown, Jozsef Vinkó, Jeffrey M. Silverman, David J. Sand | Summary: We report evidence for excess blue light from the Type Ia supernova SN 2012cg at fifteen and sixteen days before maximum B-band brightness. The emission is consistent with predictions for the […]
