On the relationship between Type Ia supernova luminosity and host-galaxy properties
Yukei S. Murakami, Benjamin E. Stahl, Keto D. Zhang +4
A string of recent studies has debated the exact form and physical origin of an evolutionary trend between the peak luminosity of Type Ia supernovae (SNe Ia) and the properties of…
Improving Bayesian posterior correlation analysis on Type Ia supernova luminosity evolution
Keto D. Zhang, Yukei S. Murakami, Benjamin E. Stahl +2
Much of the cosmological utility thus far extracted from Type Ia supernovae (SNe Ia) relies on the assumption that SN~Ia peak luminosities do not evolve significantly with the age…
Brightest Cluster Galaxies: the centre can(not?) hold
Roberto De Propris, Michael J. West, Felipe Andrade-Santos +9
We explore the persistence of the alignment of brightest cluster galaxies (BCGs) with their local environment. We find that a significant fraction of BCGs do not coincide with the…
The continuing search for evidence of tidal orbital decay of hot Jupiters
Kishore C. Patra, Joshua N. Winn, Matthew J. Holman +15
Many of the known hot Jupiters are formally unstable to tidal orbital decay. The only hot Jupiter for which orbital decay has been directly detected is WASP-12, for which transit t…
