Black Hole

Lensing of space time around a black hole. At Oxford we study black holes observationally and theoretically on all size and time scales - it is some of our core work.

Galaxies in the first billion years: Implications for re-ionization and the star formation history at z>6

Proceedings of the International Astronomical Union 2:14 (2006) 248

Authors:

AJ Bunker, ER Stanway, LP Eyles, RS Ellis, RG McMahon, M Lacy, DP Stark

Abstract:

We discuss the selection of star-forming galaxies at z6 through the Lyman-break technique. Spitzer imaging implies many of these contain older stellar populations (>200Myr) which produce detectable Balmer breaks. The ages and stellar masses (1010M) imply that the star formation rate density at earlier epochs may have been significantly higher than at z6, and might have played a key role in re-ionizing the universe. © 2007 International Astronomical Union.
