Rest-frame UV Properties of Luminous Strong Gravitationally Lensed Ly Emitters from the BELLS GALLERY Survey
R. Marques-Chaves, I. Pérez-Fournon, Y. Shu +15
We present deep rest-frame UV spectroscopic observations using the Gran Telescopio Canarias of six gravitationally lensed Lya emitters (LAEs) at selected from the BEL…
An accurate analytic mass model for lensing galaxies
Wei Du, Gong-Bo Zhao, Zuhui Fan +3
We develop an analytic mass model for lensing galaxies, based on a broken power-law (BPL) density profile, which is a power-law profile with a mass deficit or surplus in the centra…
Catalogues of Active Galactic Nuclei From Gaia and unWISE Data
Yiping Shu, Sergey E. Koposov, N. Wyn Evans +4
We present two catalogues of active galactic nucleus (AGN) candidates selected from the latest data of two all-sky surveys -- Data Release 2 (DR2) of the \emph{Gaia} mission and th…
Discovery of a giant and luminous Lya+CIV+HeII nebula at z=3.326 with extreme emission line ratios
R. Marques-Chaves, I. Pérez-Fournon, M. Villar-Martín +17
We present the discovery of HLock01-LAB, a luminous and large Lya nebula at z=3.326. Medium-band imaging and long-slit spectroscopic observations with the Gran Telescopio Canarias…
