Journal ArticleDOI
Near-infrared imaging and the K—z relation for radio galaxies in the 7C Redshift Survey
TL;DR: In this article, K-band imaging of all 49 radio galaxies in the 7C-I and 7c-II regions of the 7c Redshift Survey (7CRS) was presented.
Journal ArticleDOI
The WIRCam Deep Survey I. Counts, colours, and mass-functions derived from near-infrared imaging in the CFHTLS deep fields
R. M. Bielby,P. Hudelot,H. J. McCracken,O. Ilbert,Emanuele Daddi,O. Le Fevre,Violeta Gonzalez-Perez,Jean-Paul Kneib,Chiara Marmo,Yannick Mellier,Mara Salvato,David B. Sanders,Chris J. Willott +12 more
TL;DR: In this article, the authors present a new near-infrared imaging survey in the four CFHTLS deep fields: the WIRCam Deep Survey or “WIRDS”, which consists of extremely deep, high quality (FWHM ǫ 0.6″) J, H, and K s imaging covering a total effective area of 2.5.
Journal ArticleDOI
The obscuration by dust of most of the growth of supermassive black holes
A. Martinez-Sansigre,Steve Rawlings,Mark Lacy,Dario Fadda,Francine R. Marleau,Chris Simpson,Chris J. Willott,Matt J. Jarvis +7 more
TL;DR: It is concluded that the direct detection of a population of distant type-2 quasars, which is at least comparable in size to the well-known unobscured type-1 population, is responsible for most of the black-hole growth in the young Universe and that, throughout cosmic history, black- hole growth occurs in the dusty, gas-rich centres of active galaxies.
Journal ArticleDOI

TL;DR: In this paper, the authors studied the UV luminosity functions (LFs) at 4, 5, 6, and 7$ on the 100 deg$^2$ sky of the Hyper Suprime-Cam (HSC) strategic program (SSP).
