BoRG Cycle 22 observations started on October 27, 2014 with the first out of more than 110 planned fields acquired. Here is a preview with an optical+near-IR color composite:
BoRG Cycle 22 is approved for 32 days of observing time!
A new BoRG survey has been approved for Cycle 22! We boldly proposed to extend the search for the brightest galaxies that Hubble can detect, focusing on redshift z~10 (just 500 Myr after the Big Bang), and we obtained what…
New Website
We are very pleased to have put our new BoRG website online (http://borg.astro.ucla.edu). The BoRG collective server has migrated away from wolf359, previously hosted at the University of Colorado, and has taken residence at University of California, Santa Barbara.
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…
Full BoRG Cycle 17+19+20 data release
We are pleased to announce that with the publication of the BoRG paper by Schmidt et al. (2014), we have also released science grade reduced and aligned images to the public through the Hubble Archive to encompass all fields observed…
BoRG Presentation at HST4
The latest results from the BoRG survey were presented by PI Michele Trenti at the Hubble Space Telescope 4: Looking to the Future conference in Rome on March 19, 2014. PDF slides of the presentation: “Random Sights with Hubble: the…
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$$\mathring{A}$$…
