VizieR online Data Catalogue associated with article published in journal Astronomical Journal (AAS) with title 'Improving cosmological distance measurements using twin Type Ia supernovae.' (bibcode:
Constraining systematic uncertainties is critical to accurately and confidently use type Ia supernovae as precise cosmological distance indicators. The two dominant astrophysical systematics in optic
In this paper, we explore the possibility of using the Wesenheit function to derive individual distances to Galactic Cepheids, as the dispersion of the reddening-free Wesenheit...
