Journal ArticleDOI

The Hubble Space Telescope Cluster Supernova Survey. V. Improving the Dark-energy Constraints above z > 1 and Building an Early-type-hosted Supernova Sample

Nao Suzuki, +84 more
TL;DR: In this article, Advanced Camera for Surveys, NICMOS and Keck adaptive-optics-assisted photometry of 20 Type Ia supernovae (SNe Ia) from the Hubble Space Telescope (HST) Cluster Supernova Survey was presented.
Journal ArticleDOI

Strong dependence of Type Ia supernova standardization on the local specific star formation rate

TL;DR: In this article, a large sample of nearby Type Ia supernovae (SN Ia) is classified into those that are located in predominantly younger or older environments, based on the specific star formation rate measured within a projected distance of 1 kpc from each SN location.
Journal ArticleDOI

The XMM cluster survey:Galaxy morphologies and the color-magnitude relation in XMMXCS J2215.9 - 1738 at z = 1.46

TL;DR: In this paper, the morphological fraction and color-magnitude relation (CMR) in the most distant X-ray selected galaxy cluster currently known, XMMXCS J2215.9 − 1738 at z = 1.46, using a combination of optical imaging data obtained with the Hubble Space Telescope Advanced Camera for Surveys, and infrared data from the Multi-Object Infrared Camera and Spectrograph, mounted on the 8.2 m Subaru telescope.
