Estimating the BoRG z~8 luminosity function, Schmidt et al. (2014) presented a Bayesian framework for obtaining robust and un-biased luminosity functions of samples of photometrically selected Lyman Break galaxies (or any other samples of galaxies for that matter). Mason et al. (2015) extended…
First results from the [z9-10] BoRG survey!
BoRG postdoc Valentina Calvi (STSci) published the first results from the z~9-10 BoRG survey in the Astrophysical Journal. In ~25% of the total area in the survey we find 5 galaxy candidates at z ~ 8.3 – 10 detected at…
Spitzer follow-up of BoRG z>=9 candidates accepted!
BoRG collaborator Rychard Bouwens (Leiden University) has been awarded up to 25.8 hours of priority 1 observing time with Spitzer/IRAC to follow-up BoRG sources! Spitzer/IRAC will provide the much needed IR observations to distinguish between the true z ~ 9…
Magnification bias in the BoRG luminosity function
BoRG graduate student Charlotte Mason (UCSB) has developed a Bayesian framework to account for the magnification bias from gravitational lensing in luminosity functions, and used the BoRG z~8 LF as a test case. Magnification bias can distort the bright end…
Welcome
The Brightest of Reionizing Galaxies Survey is a large Hubble Space Telescope Program focused on finding rare and bright galaxy candidates at redshift z~8-10, that is when the Universe was about 500 to 650 million years old. We use Hubble’s…
Exciting follow-up campaign in 2013

BoRG discovers the farthest proto-cluster of galaxies
The latest exciting BoRG discovery: Hubble Pinpoints Farthest Protocluster of Galaxies Ever Seen Slides from Michele’s media briefing at the AAS meeting can be downloaded here. The scientific paper discussing our discovery was published in The Astrophysical Journal in February…
