Further evidence for significant luminosity evolution in supernova cosmology
Young-Wook Lee, Chul Chung, Yijung Kang +1
Supernova (SN) cosmology is based on the assumption that the corrected luminosity of SN Ia would not evolve with redshift. Recently, our age dating of stellar populations in early-…
Early-type Host Galaxies of Type Ia Supernovae. II. Evidence for Luminosity Evolution in Supernova Cosmology
Yijung Kang, Young-Wook Lee, Young-Lo Kim +2
The most direct and strongest evidence for the presence of dark energy is provided by the measurement of galaxy distances using SNe Ia. This result is based on the assumption that…
Environmental Dependence of Type Ia Supernova Luminosities from the YONSEI Supernova Catalog
Young-Lo Kim, Yijung Kang, Young-Wook Lee
There is growing evidence for the dependence of Type Ia supernova (SN Ia) luminosities on their environments. While the impact of this trend on estimating cosmological parameters i…
The Globular Cluster Origin of the Milky Way Outer Bulge: Evidence from Sodium Bimodality
Young-Wook Lee, Jenny J. Kim, Christian I. Johnson +4
Recent investigations of the double red clump in the color-magnitude diagram of the Milky Way bulge cast serious doubts on the structure and formation origin of the outer bulge. Un…
