Systematic errors on optical-SED stellar mass estimates for galaxies across cosmic time and their impact on cosmology
Systematic errors on optical-SED stellar mass estimates for galaxies across cosmic time and their impact on cosmology
Studying galaxies at different cosmic epochs entails several
observational effects that need to be taken into account to compare
populations across a large time span in a consistent manner. We use a
sample of 166 nearby galaxies that hosted type Ia supernovae (SNe Ia)
and have been observed with the integral field spectrograph MUSE through
the AMUSING survey. Here, we present a study of the systematic errors
and bias in the host stellar mass with increasing redshifts that are
generally overlooked in SNe Ia cosmological analyses. We simulate
observations at different redshifts (0.1

Abstract
Studying galaxies at different cosmic epochs entails several
observational effects that need to be taken into account to compare
populations across a large time span in a consistent manner. We use a
sample of 166 nearby galaxies that hosted type Ia supernovae (SNe Ia)
and have been observed with the integral field spectrograph MUSE through
the AMUSING survey. Here, we present a study of the systematic errors
and bias in the host stellar mass with increasing redshifts that are
generally overlooked in SNe Ia cosmological analyses. We simulate
observations at different redshifts (0.1
