Using 4MOST to refine the measurement of galaxy properties: A case study of Supernova hosts

Understand

The Rubin Observatory's 10-year Legacy Survey of Space and Time will observe near to 20 billion galaxies.

• For each galaxy the properties can be inferred.
• Approximately $10^5$ galaxies observed per year will contain Type Ia supernovae (SNe), allowing SN host-galaxy properties to be calculated on a large scale.
• Measuring the properties of SN host-galaxies serves two main purposes.
