Leveraging SN Ia spectroscopic similarity to improve the measurement of
Yukei S. Murakami, Adam G. Riess, Benjamin E. Stahl +7
Recent studies suggest spectroscopic differences explain a fraction of the variation in Type Ia supernova (SN Ia) luminosities after light-curve/color standardization. In this work…
Cosmicflows-4
R. Brent Tully, Ehsan Kourkchi, Hélène M. Courtois +14
With Cosmicflows-4, distances are compiled for 55,877 galaxies gathered into 38,065 groups. Eight methodologies are employed, with the largest numbers coming from the correlations…
A 5% measurement of the Hubble constant from Type II supernovae
T. de Jaeger, L. Galbany, A. G. Riess +4
The most stringent local measurement of the Hubble-Lemaître constant from Cepheid-calibrated Type Ia supernovae (SNe~Ia) differs from the value inferred via the cosmic microwave ba…
The Pantheon+ Analysis: Cosmological Constraints
Dillon Brout, Dan Scolnic, Brodie Popovic +43
We present constraints on cosmological parameters from the Pantheon+ analysis of 1701 light curves of 1550 distinct Type Ia supernovae (SNe Ia) ranging in redshift from t…
A Comprehensive Measurement of the Local Value of the Hubble Constant with 1 km/s/Mpc Uncertainty from the Hubble Space Telescope and the SH0ES Team
Adam G. Riess, Wenlong Yuan, Lucas M. Macri +15
We report observations from HST of Cepheids in the hosts of 42 SNe Ia used to calibrate the Hubble constant (H0). These include all suitable SNe Ia in the last 40 years at z<0.01,…
The Pantheon+ Analysis: The Full Dataset and Light-Curve Release
Dan Scolnic, Dillon Brout, Anthony Carr +27
Here we present 1701 light curves of 1550 spectroscopically confirmed Type Ia supernovae (SNe Ia) that will be used to infer cosmological parameters as part of the Pantheon+ SN ana…
Peculiar-velocity cosmology with Types Ia and II supernovae
Benjamin E. Stahl, Thomas de Jaeger, Supranta S. Boruah +3
We present the Democratic Samples of Supernovae (DSS), a compilation of 775 low-redshift Type Ia and II supernovae (SNe Ia & II), of which 137 SN Ia distances are derived via the n…
The snapshot distance method: estimating the distance to a Type Ia supernova from minimal observations
Benjamin E. Stahl, Thomas de Jaeger, WeiKang Zheng +1
We present the snapshot distance method (SDM), a modern incarnation of a proposed technique for estimating the distance to a Type Ia supernova (SN Ia) from minimal observations. Ou…
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…
A measurement of the Hubble constant from Type II supernovae
T. de Jaeger, B. E. Stahl, W. Zheng +3
Progressive increases in the precision of the Hubble-constant measurement via Cepheid-calibrated Type Ia supernovae (SNe Ia) have shown a discrepancy of with the curren…
The XMM Cluster Survey: evolution of the velocity dispersion -- temperature relation over half a Hubble time
Susan Wilson, Matt Hilton, Philip J. Rooney +26
We measure the evolution of the velocity dispersion--temperature (--) relation up to using a sample of 38 galaxy clusters drawn from the \textit{XMM}…
