TL;DR: In this article, the authors presented cosmological constraints from a joint analysis of type Ia supernova (SN Ia) observations obtained by the SDSS-II and SNLS collaborations.

TL;DR: In this article, a detailed analysis of the spectroscopic catalog of galaxies in the Coma Cluster from Mobasher et al. is presented, which consists of ~300 spectra of cluster members with absolute magnitudes in the range MB = -20.5 to -14 in two areas of ~1 × 1.5 Mpc toward the center and the southwest region of the cluster.

A photometric and spectroscopic study of dwarf and giant galaxies in the Coma cluster -- III. Spectral ages and metallicities
Bianca M. Poggianti,Terry J. Bridges,Bahram Mobasher,David Carter,M. Doi,Masanori Iye,Nobunari Kashikawa,Yutaka Komiyama,Sadanori Okamura,Maki Sekiguchi,Kazuhiro Shimasaku,Masafumi Yagi,Naoki Yasuda +12 more
TL;DR: The analysis of the spectroscopic catalog of galaxies in the Coma cluster from Mobasher et al. as discussed by the authors is restricted to the 257 galaxies with no emission lines in their spectra and the strength of the age sensitive indices is found to correlate with galaxy magnitude over the whole magnitude range.
