THE CANADA-FRANCE HIGH-z QUASAR SURVEY: NINE NEW QUASARS AND THE LUMINOSITY FUNCTION AT REDSHIFT 6
Chris J. Willott,Philippe Delorme,Céline Reylé,Loic Albert,Jacqueline Bergeron,David Crampton,Xavier Delfosse,Thierry Forveille,J. B. Hutchings,Ross J. McLure,Alain Omont,David Schade +11 more
TL;DR: In this paper, the authors presented discovery imaging and spectroscopy for nine new z ∼ 6 quasars found in the Canada-France High-z Quasar Survey (CFHQS) bringing the total number of CFHQS quasARS to 19.
Journal ArticleDOI
Hubble Space Telescope imaging of the CFRS and LDSS redshift surveys—IV. Influence of mergers in the evolution of faint field galaxies from z∼1
O. Le Fevre,Roberto Abraham,Simon J. Lilly,Rowan Ellis,Jarle Brinchmann,David Schade,Laurence Tresse,Matthew Colless,David Crampton,Karl Glazebrook,Francois Hammer,Tom Broadhurst +11 more
TL;DR: In this article, the authors derived a merger fraction varying with redshift as /O1a zU 3:2^0:6, after correction for line-of-sight contamination, in excellent agreement with the merger fraction derived from the visual classification of mergers.
Journal ArticleDOI
Eddington-limited Accretion and the Black Hole Mass Function at Redshift 6
Chris J. Willott,Loic Albert,Doris Arzoumanian,Jacqueline Bergeron,David Crampton,Philippe Delorme,J. B. Hutchings,Alain Omont,Céline Reylé,David Schade +9 more
TL;DR: In this paper, a quasar in the Canada-France High-z Quasar Survey (CFHQS) at redshift z = 6.44 was found to have a strong correlation between Mg II FWHM and UV luminosity and that most quasars at this early epoch are accreting close to the Eddington limit.
Journal ArticleDOI
Four Quasars above Redshift 6 Discovered by the Canada-France High-z Quasar Survey
Chris J. Willott,Philippe Delorme,Alain Omont,Jacqueline Bergeron,Xavier Delfosse,Thierry Forveille,Loic Albert,Céline Reylé,Gary J. Hill,Michael Gully-Santiago,Phillip Vinten,David Crampton,J. B. Hutchings,David Schade,Luc Simard,Marcin Sawicki,Alexandre Beelen,Pierre Cox +17 more
TL;DR: In this article, the discovery of the first four Canada-France High-z Quasar Survey (CFHQS) quasars at redshifts greater than 6 was presented, including the most distant known quasar, CFHQS J2329-0301 at z = 6.43.
Journal ArticleDOI
Hubble Space Telescope Imaging of the CFRS and LDSS Redshift Surveys. I. Morphological Properties
Jarle Brinchmann,Roberto Abraham,David Schade,Laurence Tresse,Richard S. Ellis,Simon J. Lilly,Olivier Le Fevre,Karl Glazebrook,Francois Hammer,Matthew Colless,David Crampton,Tom Broadhurst +11 more
TL;DR: In this article, a complete sample of 341 galaxies drawn from the CFRS and LDSS ground-based redshift surveys is analyzed and each galaxy has been morphologically classified according to a scheme similar to that developed for the Medium Deep Survey.
