We present the first measurement of the faint end of the QSO luminosity function at z = 3. The QSOs, which range from M1450 = -21 to M1450 = -27, were discovered in 17 fields totaling 0.43 deg 2 using multicolor selection criteria (the Lyman break technique) and spectroscopic follow-up. We find that the faint-end slope of the luminosity function is βl = 1.24 ± 0.07 (Φ ∝ L), flatter than the value of βl = 1.64 ± 0.18 measured at lower redshift. The integrated rest 1450 Å UV luminosity of z = 3…

THE FAINT END OF THE QUASAR LUMINOSITY FUNCTION AT z ∼ 4: IMPLICATIONS FOR IONIZATION OF THE INTERGALACTIC MEDIUM AND COSMIC DOWNSIZING
We present an updated determination of the z ∼ 4 QSO luminosity function (QLF), improving the quality of the determination of the faint end of the QLF presented by Glikman et al. (2010). We have
PROBING THE FAINT END OF THE QUASAR LUMINOSITY FUNCTION AT z∼ 4 IN THE COSMOS FIELD
We searched for quasars that are ∼3 mag fainter than the SDSS quasars in the redshift range 3.7 ≲ z ≲ 4.7 in the COSMOS field to constrain the faint end of the quasar luminosity function (QLF). Using

In this paper, we provide updated constraints on the bolometric quasar luminosity function (QLF) from z = 0 to z = 7. The constraints are based on an observational compilation that includes
The X-ray luminosity function of AGN at z∼ 3
We combine Lyman-break colour selection with ultradeep (200 ks) Chandra X-ray imaging over a survey area of ∼0.35 deg 2 to select high-redshift active galactic nuclei (AGN). Applying careful
High-Redshift QSOs in the SWIRE Survey and the z~3 QSO Luminosity Function
We use a simple optical/infrared (IR) photometric selection of high-redshift QSOs that identifies a Lyman break in the optical photometry and requires a red IR color to distinguish QSOs from common

Evolution of the AGN UV luminosity function from redshift 7.5
Determinations of the ultraviolet (UV) luminosity function of active galactic nuclei (AGN) at high redshifts are important for constraining the AGN contribution to reionization and understanding the
CONSTRAINTS ON THE FAINT END OF THE QUASAR LUMINOSITY FUNCTION AT z ∼ 5 IN THE COSMOS FIELD
We present the result of our low-luminosity quasar survey in the redshift range of 4.5 ≲ z ≲ 5.5 in the COSMOS field. Using the COSMOS photometric catalog, we selected 15 quasar candidates with 22 <
An Observational Determination of the Bolometric Quasar Luminosity Function
We combine a large set of quasar luminosity function (QLF) measurements from the rest-frame optical, soft and hard X-ray, and near- and mid-IR bands to determine the bolometric QLF in the redshift
The VVDS type-1 AGN sample: the faint end of the luminosity function
In a previous paper (Gavignaud et al. 2006), we presented the type-1 Active Galactic Nuclei (AGN) sample obtained from the first epoch data of the VIMOS-VLT Deep Survey (VVDS). The sample consists of
