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…
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…
Latest BoRG luminosity function at z~8
BoRG postdoc Kasper Borello Schmidt published the latest determination of the z~8 BoRG luminosity function in the Astrophysical Journal. The luminosity function measured by combining BoRG data with deeper data from the Hubble Ultradeep Field and ERS observations is shown…
BoRG Cool Stars
BoRG CoI Benne Holwerda (Leiden University) took advantage of the random pointings nature of BoRG to investigate the distribution of cool stars (primarily M dwarfs) in the Milky Way. The work has been accepted for publication in the Astrophysical Journal…
BoRG@Keck: Witnessing reionization in progress
BoRG CoI Tommaso Treu led a spectroscopic follow-up of 13 BoRG z~8 galaxies to search for Ly-$$\alpha$$ emission. The results have been published in the Astrophysical Journal. The lack of Ly-$$\alpha$$ detection to a faint flux (median sensitivity of 25$$\mathring{A}$$…
z~8 LF function from the BoRG team
The best determination yet from Hubble data! http://adsabs.harvard.edu/abs/2012ApJ…760..108B
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…
