This work was part of the Carnegie Supernova Project II, a National Science Foundation-funded program to observe supernovae. Carnegie Supernova Project-II: The Near-infrared Spectroscopy Program* E.

Hsiao. Although this object spectroscopically resembles the well-observed SN 2010jl, it does exhibit different LC evolution and dust signatures. The first phase of the Carnegie Supernova Project (CSP-I) was a dedicated supernova follow-up program based at the Las Campanas Observatory that collected science data of young, low-redshift supernovae between 2004 and 2009. 2019; Hsiao et al.

An analysis of the first set of low-redshift (z < 0.08) Type Ia supernovae (SNe Ia) monitored by the Carnegie Supernova Project between 2004 and 2006 is presented. Type Ia supernovae also provide the most powerful observational tool currently available for studying the expansion history of the universe and the nature of dark energy. The SN reached a peak r-band absolute magnitude of ˇ19 mag and an even brighter UV peak, and its light curve evolution resembles that of SN 1988Z. We analyse four colours (B - V, u - g, g - r, and g - Y) and find that SN II colour curves can be described by two linear regimes during the photospheric phase.
