Abstract:
We report on work to increase the number of well-measured Type Ia
supernovae (SNe Ia) at high redshifts. Light curves, including high
signal-to-noise Hubble Space Telescope data, and spectra of six SNe Ia
that were discovered during 2001, are presented. Additionally, for the
two SNe with z>1, we present ground-based J-band photometry from
Gemini and the Very Large Telescope. These are among the most distant
SNe Ia for which ground-based near-IR observations have been obtained.
We add these six SNe Ia together with other data sets that have
recently become available in the literature to the Union compilation.
We have made a number of refinements to the Union analysis chain, the
most important ones being the refitting of all light curves with the
SALT2 fitter and an improved handling of systematic errors. We call
this new compilation, consisting of 557 SNe, the Union2 compilation.
Description:
During spring 2001, nine instruments were used for the photometric
follow-up : CFHT/CFH12k, CTIO/MOSAIC II, VLT/FORS1, VLT/ISAAC (Js
filter), NTT/SuSI2, Gemini/NIRI (J filter), HST/ACS, HST/WFPC2,
Subaru/SuprimeCam. All observations are listed in Table 12 (B1 in the
paper).
