Stellar populations in the Milky Way bulge region : Towards solving the Galactic bulge and bar shapes using 2MASS data

Annie C. Robin, Douglas J. Marshall, Mathias Schultheis +1

We re-analyse photometric near-infrared data in order to investigate why it is so hard to get a consensus for the shape and density law of the bulge, as seen from the literature. T…

Eddington-limited accretion and the black hole mass function at redshift 6

Chris J. Willott, Loic Albert, Doris Arzoumanian +7

We present discovery observations of a quasar in the Canada-France High-z Quasar Survey (CFHQS) at redshift z=6.44. We also use near-IR spectroscopy of nine CFHQS quasars at z~6 to…

The Canada-France High-z Quasar Survey: nine new quasars and the luminosity function at redshift 6

Chris J. Willott, Philippe Delorme, Celine Reyle +9

We present 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. B…

Four quasars above redshift 6 discovered by the Canada-France High-z Quasar Survey

Chris J. Willott, Philippe Delorme, Alain Omont +15

The Canada-France High-z Quasar Survey (CFHQS) is an optical survey designed to locate quasars during the epoch of reionization. In this paper we present the discovery of the first…

CFBDSIR J1458+1013B: A Very Cold (>T10) Brown Dwarf in a Binary System

Michael C. Liu, Philippe Delorme, Trent J. Dupuy +6

We have identified CFBDS J1458+10 as a 0.11" (2.6 AU) physical binary using Keck laser guide star adaptive optics imaging and have measured a distance of 23.1+/-2.4 pc to the syste…

On high proper motion white dwarfs from photographic surveys

Celine Reyle, Annie C. Robin, Michel Creze

The interpretation of high proper motion white dwarfs detected by Oppenheimer et al (2001) was the start of a lively controversy. While the discoverers identify a large fraction of…
