"Refsdal" meets Popper: comparing predictions of the re-appearance of the multiply imaged supernova behind MACSJ1149.5+2223
T. Treu, G. Brammer, J. M. Diego +25
Supernova "Refsdal," multiply imaged by cluster MACSJ1149.5+2223, represents a rare opportunity to make a true blind test of model predictions in extragalactic astronomy, on a time…
Two Type Ia Supernovae at Redshift ~2 : Improved Classification and Redshift Determination with Medium-band Infrared Imaging
Steven A. Rodney, Adam G. Riess, Daniel M. Scolnic +9
We present two supernovae (SNe) discovered with the Hubble Space Telescope (HST) in the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS), an HST multi-cycle…
Illuminating a Dark Lens : A Type Ia Supernova Magnified by the Frontier Fields Galaxy Cluster Abell 2744
Steven A. Rodney, Brandon Patel, Daniel Scolnic +27
SN HFF14Tom is a Type Ia Supernova (SN) discovered at z = 1.3457 +- 0.0001 behind the galaxy cluster Abell 2744 (z = 0.308). In a cosmology-independent analysis, we find that HFF14…
Multiple Images of a Highly Magnified Supernova Formed by an Early-Type Cluster Galaxy Lens
Patrick L. Kelly, Steven A. Rodney, Tommaso Treu +28
In 1964, Refsdal hypothesized that a supernova whose light traversed multiple paths around a strong gravitational lens could be used to measure the rate of cosmic expansion. We rep…
CANDELS+3D-HST: compact SFGs at z~2-3, the progenitors of the first quiescent galaxies
G. Barro, S. M. Faber, P. G. Perez-Gonzalez +32
We analyze the star-forming and structural properties of 45 massive (log(M/Msun)>10) compact star-forming galaxies (SFGs) at 2<z<3 to explore whether they are progenitors of compac…
The Discovery of the Most Distant Known Type Ia Supernova at Redshift 1.914
David O. Jones, Steven A. Rodney, Adam G. Riess +22
We present the discovery of a Type Ia supernova (SN) at redshift from the CANDELS multi-cycle treasury program on the \textit{Hubble Space Telescope (HST)}. This SN was…
