Using Nearby Type Ia Supernovae to Measure Cosmological Distances

Mathilda Nillson

Type Ia supernovae in the near infrared can provide robust and accurate measurements of distance in the Universe.  Here we present data from the SweetSpot survey which ran from 2013-2016 on the KPNO WIYN 3.5-m telescope.  These infrared data will help identify aspects of supernova astrophysics and dust to improve the utility of supernovae as standard candles and to increase the power of the low-redshift anchor for distance measurements with the upcoming with the upcoming Vera C. Rubin LSST survey and the future Nancy Grace Roman Space Telescope time-domain survey.

 

This poster will be displayed on Monday and Tuesday.
