Feeling Blue: Constructing a Robust SALT3 UV Template and Constraining its Redshift Dependency
Qinan Wang, David O. Jones, Justin D. R. Pierel +13
Upcoming cosmological surveys will obtain numerous rest-frame ultraviolet (UV) observations of Type Ia supernovae (SNe Ia), yet there is concern about how standardizable SNe Ia are…
Tip of the Red Giant Branch Distances to NGC 1316, NGC 1380, NGC 1404, & NGC 4457: A Pilot Study of a Parallel Distance Ladder Using Type Ia Supernovae in Early-Type Host Galaxies
Max J. B. Newman, Conor Larison, Saurabh W. Jha +10
Though type-Ia supernovae (SNe Ia) are found in all types of galaxies, recent local Hubble constant measurements have disfavored using SNe Ia in early-type or quiescent galaxies, a…
The Samples and Binary Fractions of Red Supergiant in M31 and M33 by the HST Observations
Min Dai, Shu Wang, Biwei Jiang +1
The binarity of red supergiants (RSGs) influences their evolution and the fate of supernovae. We investigate the binary fraction of RSGs in the Andromeda Galaxy (M31) and Triangulu…
The Binary Fraction of Red Supergiants in the Magellanic Clouds
Min Dai, Shu Wang, Biwei Jiang
Red supergiants (RSGs), as the descendants of OB-type stars and the progenitors of supernovae, provide crucial insights into the evolution of massive stars, particularly in binary…
