J. Meyers, et al., ApJ (2012). L12-L16 (2009). The lines are from different cosmological models. The Supernova Cosmology Project Its digital images were compared with earlier images using “subtraction” software. The physicists and astronomers who worked on the High-Z Supernova Search Team and the Supernova Cosmology Project are the ones who determined that the universe is expanding at an accelerating rate. There has been another research team called Carnegie Supernovae Project who has given similar results. The new study reinforces the remarkable discovery, announced by the Supernova Cosmology Project early in 1998, that the expansion of the universe is accelerating due to a mysterious energy that pervades all space.

The international Supernova Cosmology Project (SCP), based at the U.S. Department of Energy's Lawrence Berkeley National Laboratory, has announced the … Members of the Supernova Cosmology Project expected to find, as did their rivals in the High-Z Supernova Search Team, that the farther away (the farther back in time) a supernova was, the brighter (closer) it would appear relative to its redshift — an indication that expansion has been slowing. III. The project is headed by Saul Perlmutter at Lawrence Berkeley National Laboratory, with members from Australia, Chile, France, Portugal, Spain, Sweden, the United Kingdom, and the United States. That finding was based on data from over three dozen Type Ia supernovae, all but one of them observed from the ground. The Supernova Cosmology Project concluded that these distant supernovae were receding more quickly than would be expected due to the Hubble expansion alone, and, by inference, the expansion of the universe must have been accelerated over the billions of years since the supernovae occurred.

Hierarchical Bayesian models are perfect for incorporating subtle effects into our model, and so I made one to do just that. Labeled SN SCP-0401, the supernova is exceptional for its detailed spectrum and precision color measurement, unprecedented in a supernova so distant. The thin solid line is a constant expansion. You may have heard of dark energy, and this is in fact the same thing: the evidence for dark energy is that the universe is accelerating. Before-and-after pictures (and Hubble Space Telescope picture) of a high-redshift supernovae discovered by the Supernova Cosmology Project in March, 1998. Shortly afterward, the first precise measurements that determined the geometry of the Universe (and therefore Ω) were the measurements of the tiny temperature variations in the CMB.
