| description | The number of type Ia supernova (SNe Ia) observations will grow significantly
within the next decade, mainly thanks to the Legacy Survey of Space and Time
(LSST) undertaken by the Vera Rubin Observatory in Chile. With this
improvement, statistical uncertainties will decrease, and flux calibration will
become the main uncertainty for the characterization of dark energy. Currently,
the astronomical flux scale is anchored on the numerical models of white dwarf
atmospheres from the CALSPEC catalog, and every error on the model can induce a
bias over cosmological parameters inference. The StarDICE experiment proposes a
new calibration reference that only relies on observations from the optical
watt defined by the NIST towards the magnitude of standard stars. It is
currently operating at l'Observatoire de Haute-Provence and has been collecting
data since the beginning of 2023. To overcome the photometric calibration
uncertainty and reach a sub-percent precision, the instrument throughput has
been calibrated with a Collimated Beam Projector. It will be monitored on-site
with a LED-based artificial star source calibrated with NIST photodiodes. In
this proceeding, we will first illustrate how an error in the photometric
calibration can impact the SNe Ia distance moduli and thus bias the measurement
of cosmological parameters. Then we will present the StarDICE experiment and
how we can recalibrate the CALSPEC catalog at the millimagnitude level on the
NIST scale with photometric analysis. |
