TL;DR: In this article, the first conclusive evidence for cosmic deceleration that preceded the current epoch of cosmic acceleration was provided by the discovery of 16 Type Ia supernovae with the Hubble Space Telescope (HST).

TL;DR: The Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey (CANDELS) as mentioned in this paper was designed to document the evolution of galaxies and black holes at $z\sim 1.5-8$, and to study Type Ia SNe beyond $z>1.5.
Journal ArticleDOI
Large Magellanic Cloud Cepheid Standards Provide a 1% Foundation for the Determination of the Hubble Constant and Stronger Evidence for Physics Beyond LambdaCDM
TL;DR: In this paper, an improved determination of the Hubble constant (H0) from HST observations of 70 long-period Cepheids in the Large Magellanic Cloud was presented.
Journal ArticleDOI

TL;DR: In this article, a selected sample of 50 long-period, low-extinction Milky Way Cepheids measured on the same WFC3 F555W, F814W, and F160W-band photometric system as extragalactic Cepsheids in SN Ia hosts were observed with the optical and near-infrared to mitigate saturation and reduce pixel-to-pixel calibration errors.
