MCP Working Group

The Megamaser Cosmology Project (MCP)

Dark Energy is the dominant component of the current mass/energy budget in the universe, but little is known about it. The goal of the MCP is to improve our understanding of Dark Energy by measuring the Hubble Constant, H_0, with unprecedented accuracy (< 3%). We aim to measure distances to about 10 galaxies in the Hubble Flow using the "maser distance" technique pioneered on NGC 4258. A more detailed description of the science is available on the Public MCP Page.
