We present initial results from the Subaru Strategic Program (SSP) with Hyper Suprime-Cam (HSC) on a comprehensive survey of emission-line galaxies at z < 1.5 based on narrowband imaging. The first Public Data Release (PDR1) provides us with data from two narrowband filters, specifically NB816 and NB921 over 5.7 deg 2 and 16.2 deg 2 respectively. The 5σ limiting magnitudes are 25.2 (UltraDeep layer, 1.4 deg 2 ) and 24.8 (Deep layer, 4.3 deg 2 ) mag in NB816, and 25.1 (UltraDeep, 2.9 deg 2 ) and 24.6-24.8 (Deep, 13.3 deg 2 ) mag in NB921. The wide-field imaging allows us to construct unprecedentedly large samples of 8,054 Hα emitters c 2017. Astronomical Society of Japan. 2Publications of the Astronomical Society of Japan, (2017), Vol. 00, No. 0 at z ≈ 0. 25 and 0.40, 8,656 [OIII] emitters at z ≈ 0. 63 and 0.84, and 16,877 [OII] emitters at z ≈ 1.19 and 1.47. We map the cosmic web on scales out to about 50 comoving Mpc that includes galaxy clusters, identified by red sequence galaxies, located at the intersection of filamentary structures of star-forming galaxies. The luminosity functions of emission-line galaxies are measured with precision and consistent with published studies. The wide field coverage of the data enables us to measure the luminosity functions up to brighter luminosities than previous studies. The comparison of the luminosity functions between the different HSC-SSP fields suggests that a survey volume of > 5 × 10 5 Mpc 3 is essential to overcome cosmic variance. Since the current data have not reached the full depth expected for the HSC-SSP, the color cut in i−NB816 or z−NB921 induces a bias towards star-forming galaxies with large equivalent widths, primarily seen in the stellar mass functions for the Hα emitters at z ≈ 0.25-0.40. Even so, the emission-line galaxies clearly cover a wide range of luminosity, stellar mass, and environment, thus demonstrating the usefulness of the narrowband data from the HSC-SSP to investigate star-forming galaxies at z < 1.5.

We present the first Public Data Release (PDR-1) of the VIMOS Public Extragalactic Survey (VIPERS). It comprises 57 204 spectroscopic measurements together with all additional information necessary for optimal scientific exploitation of the data, in particular the associated photometric measurements and quantification of the photometric and survey completeness. VIPERS is an ESO Large Programme designed to build a spectroscopic sample of 100 000 galaxies with i AB < 22.5 and 0.5 < z < 1.2 with high sampling rate ( 45%). The survey spectroscopic targets are selected from the CFHTLS-Wide five-band catalogues in the W1 and W4 fields. The final survey will cover a total area of nearly 24 deg 2 , for a total comoving volume between z = 0.5 and 1.2 of 4 × 10 7 h −3 Mpc 3 and a median galaxy redshift of z 0.8. The release presented in this paper includes data from virtually the entire W4 field and nearly half of the W1 area, thus representing 64% of the final dataset. We provide a detailed description of sample selection, observations and data reduction procedures; we summarise the global properties of the spectroscopic catalogue and explain the associated data products and their use, and provide all the details for accessing the data through the survey database (http://vipers.inaf.it) where all information can be queried interactively.

“…Silverman et al 2009;Rosario et al 2013). Aird et al (2012, hereafter A12) took a different approach, starting with a sample of galaxies out to z ∼ 1 (from the Prism Multi-object Survey: Coil et al 2011;Cool et al 2013) and determining the probability of finding an X-ray AGN within such galaxies as a function of the galaxy properties: stellar mass, redshift, and colour. A12 showed that the probability of hosting an AGN can be described by a power-law distribution of specific black hole accretion rates (hereafter, λsBHAR, the rate of black hole accretion normalised relative to the host stellar mass).…”

We use deep Chandra X-ray imaging to measure the distribution of specific black hole accretion rates (L X relative to the stellar mass of the galaxy) and thus trace AGN activity within star-forming and quiescent galaxies, as a function of stellar mass (from 10 8.5 -10 11.5 M ⊙ ) and redshift (to z ∼ 4). We adopt near-infrared selected samples of galaxies from the CANDELS and UltraVISTA surveys, extract X-ray data for every galaxy, and use a flexible Bayesian method to combine these data and to measure the probability distribution function of specific black hole accretion rates, λ sBHAR . We identify a broad distribution of λ sBHAR in both starforming and quiescent galaxies-likely reflecting the stochastic nature of AGN fuelling-with a roughly power-law shape that rises toward lower λ sBHAR , a steep cutoff at λ sBHAR 0.1−1 (in Eddington equivalent units), and a turnover or flattening at λ sBHAR 10 −3 − 10 −2 . We find that the probability of a star-forming galaxy hosting a moderate λ sBHAR AGN depends on stellar mass and evolves with redshift, shifting toward higher λ sBHAR at higher redshifts. This evolution is truncated at a point corresponding to the Eddington limit, indicating black holes may self-regulate their growth at high redshifts when copious gas is available. The probability of a quiescent galaxy hosting an AGN is generally lower than that of a star-forming galaxy, shows signs of suppression at the highest stellar masses, and evolves strongly with redshift. The AGN duty cycle in high-redshift (z 2) quiescent galaxies thus reaches ∼20 per cent, comparable to the duty cycle in star-forming galaxies of equivalent stellar mass and redshift.
