Astronomical observations reveal a major deficiency in our understanding of physics—the
detectable mass is insufficient to explain the observed motions in a huge variety of systems …

The accelerating expansion of the universe is the most surprising cosmological discovery in
many decades, implying that the universe is dominated by some form of “dark energy” with …

We report observations from the Hubble Space Telescope (HST) of Cepheid variables in the
host galaxies of 42 Type Ia supernovae (SNe Ia) used to calibrate the Hubble constant (H 0) …

We present the cosmological implications from final measurements of clustering using
galaxies, quasars, and Ly α forests from the completed Sloan Digital Sky Survey (SDSS) …

We present an improved determination of the Hubble constant from Hubble Space
Telescope (HST) observations of 70 long-period Cepheids in the Large Magellanic Cloud …

Abstract Type Ia supernovae (SNe Ia) play a key role in the fields of astrophysics and
cosmology. It is widely accepted that SNe Ia arise from thermonuclear explosions of white …

The rapidly expanding field of galaxy formation lies at the interface between astronomy,
particle physics, and cosmology. Covering diverse topics from these disciplines, all of which …

We present an analysis of the final data release of the Carnegie Supernova Project I,
focusing on the absolute calibration of the luminosity–decline rate relation for Type Ia …

We present results for a suite of 14 three-dimensional, high-resolution hydrodynamical
simulations of delayed-detonation models of Type Ia supernova (SN Ia) explosions. This …

We present here the final results of the Hubble Space Telescope (HST) Key Project to
measure the Hubble constant. We summarize our method, the results, and the uncertainties …
