A Systematic Study of Ia-CSM Supernovae from the ZTF Bright Transient Survey
A Systematic Study of Ia-CSM Supernovae from the ZTF Bright Transient Survey
Among the supernovae (SNe) that show strong interaction with the circumstellar medium, there is a rare subclass of Type Ia supernovae, SNe Ia-CSM, that show strong narrow hydrogen emission lines much like SNe IIn but on top of a diluted over-luminous Type Ia spectrum. In the only previous systematic study …
