Shortening the Baseline: Characterising Type Ia Supernovae Using
Joel M. Velasco, Paolo A. Mazzali, Christopher Ashall +8
An explorative study of Type Ia Supernovae (SNe Ia) light curves is presented. decline-rate metrics are used to evaluate alternative characterisations of light curve di…
The Search for Stable Nickel: Investigating the Origins of Type Ia Supernovae with Late-time NIR Spectroscopy from the Carnegie Supernova Project-II
Sahana Kumar, Eric Y. Hsiao, Christopher Ashall +20
Producing stable Ni in Type Ia supernovae (SNe Ia) requires sufficiently high density conditions that are not predicted for all origin scenarios, so examining the distributi…
1991T-like Supernovae
M. M. Phillips, C. Ashall, Peter J. Brown +23
Understanding the nature of the luminous 1991T-like supernovae is of great importance to supernova cosmology as they are likely to have been more common in the early universe. In t…
Optical Spectroscopy of Type Ia Supernovae by the Carnegie Supernova Projects I and II
N. Morrell, M. M. Phillips, G. Folatelli +57
We present the second and final release of optical spectroscopy of Type Ia Supernovae (SNe Ia) obtained during the first and second phases of the Carnegie Supernova Project (CSP-I…
Type Ia Supernova Progenitor Properties and Their Host Galaxies
Sudeshna Chakraborty, Benjamin Sadler, Peter Hoeflich +16
We present an eigenfunction method to analyze 161 visual light curves (LCs) of Type Ia supernovae (SNe Ia) obtained by the Carnegie Supernova Project to characterize their diversit…
Newly Formed Dust within the Circumstellar Environment of SNIa-CSM 2018evt
Lingzhi Wang, Maokai Hu, Lifan Wang +44
Dust associated with various stellar sources in galaxies at all cosmic epochs remains a controversial topic, particularly whether supernovae (SNe) play an important role in dust pr…
