Schaerer Física, Astronomía y Matemáticas INFRARED: GALAXIES GALAXIES: EVOLUTION GALAXIES: HIGH REDSHIFT COSMOLOGY: EARLY UNIVERSE We present the results obtained from our deep survey of lensing clusters aimed at constraining the abundanceof star-forming galaxies at z 6-11. Lensing magnification improves the search efficiency and subsequent spec-troscopic studies with the new generation of NIR multi-object spectrographs (e.g. EMIR/GTC). The UVLuminosity Function derived from the photometric sample of candidates does not show the turnover observedat z 6-7 by Bouwens et al. (2005) towards the bright end. For this reason, the SFR density is consistent witha constant value up to z 10. This systematic trend with respect to blank fields could be due to field-to-fieldvariance, positive magnification bias from mid-z EROs, and/or residual contamination by spurious sources. 2007 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57102934 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.29 |
