TL;DR: In this article, the first results from a systematic search for high redshift Type Ia supernovae were reported, with redshift z = 0.35 − 0.46.
Journal ArticleDOI
Spatially resolved star formation relation in two HI-rich galaxies with central post-starburst signature
Anne Klitsch,Anne Klitsch,Martin Zwaan,Harald Kuntschner,Warrick J. Couch,Michael Pracy,Matt S. Owers,Matt S. Owers +7 more
TL;DR: In this article, the distribution and kinematics of atomic and molecular gas in two HI-rich galaxies were studied, which show a typical E+A spectrum at the centre and star formation at larger radii.
Proceedings ArticleDOI

TL;DR: GNOSIS as discussed by the authors uses complex aperioidc fiber Bragg gratings to suppress the 103 brightest atmospheric hydroxyl emission doublets between 1.47-1.7 μm.
Journal ArticleDOI
The kinematics and spatial distribution of stellar populations in E+A galaxies
TL;DR: This paper used the GMOS instrument on the Gemini-South telescope to obtain spatially-resolved two-colour imaging and IFU spectroscopy of a sample of ten nearby E+A galaxies.

TL;DR: Perlmutter et al. as discussed by the authors presented evidence for a low-mass density/positive cosmological-constant universe that will expand forever, based on observations of a set of 40 high-redshift supernovae.
