Research Projects

These are some of the projects that are either led by BCCP scientists, or that have heavy involvement from BCCP:



The Baryon Oscillation Spectroscopic Survey (BOSS) is a recently completed 5-year survey designed to make the best-ever measurement of the Baryon Acoustic Oscillations (BAO) signal. The survey has obtained spectra of approximately 1.5 million galaxies at z < 0.7 and 160,000 quasars at much higher redshifts.



The Polarization of Background Radiation (POLARBEAR) experiment is designed to detect B-modes in the Cosmic microwave background (CMB) and use them to investigate the origin and evolution of the Universe and to understand physics and cosmology beyond our Standard Model.


Dark Energy Survey

The Dark Energy Survey (DES) is a 5-year imaging survey currently underway. It is designed to make seasurements of supernovae, baryon acoustic oscillations, galaxy clusters and weak gravitational lensing by imaging 5000 square degrees with a new specially designed 560 megapixel camera, DECam.


Computional Cosmology Center

The Computational Cosmology Center (C3) is a focused collaboration of astrophysicists and computational scientists whose goals are to develop the tools, techniques and technologies to meet the analysis challenges posed by present and future cosmological data sets.


Supernova Cosmology Project

The Supernova Cosmology Project (SCP) probes the properties of dark energy in the first half of the universe, using supernovae at the highest redshifts available. The collaboration is currently carrying out a 2-year survey using the Hubble Space Telescope.


Nearby Supernova Factory

The Nearby Supernova Factory (SNfactory) is an experiment to develop Type Ia supernovae as tools to measure the expansion history of the Universe and explore the nature of Dark Energy.


Dark Energy Spectroscopic Instrument

The Dark Energy Spectroscopic Instrument (DESI) will measure the effect of dark energy on the expansion of the universe. It will obtain optical spectra for tens of millions of galaxies and quasars, constructing a 3-dimensional map spanning the nearby universe to 10 billion light years.


The Wide-Field Infrared Survey Telescope (WFIRST) is a NASA observatory designed to perform wide-field imaging and slitless spectroscopic surveys of the near infrared (NIR) sky for the community.
