We have carried out follow-up spectroscopy on three overdense regions of g- and r-dropout galaxies in the Canada-France-Hawaii Telescope Legacy Survey Deep Fields, finding two new protoclusters at z = 4.898 and 3.721 and a possible protocluster at z

We present near-infrared 1.1-1.3 and 1.3-1.6 μm spectra of the Ly-luminous quasar PSO J006.1240+39.2219 at z = 6.617 ± 0.003 obtained with the NIRSPEC spectrograph at the Keck II telescope. The spectra cover the C iv λ1549, C iii] λ1909 emission

For a sample of $\sim$80 local ($0.02 \leq z \leq 0.1$) Seyfert-1 galaxies with high-quality long-slit Keck spectra and spatially-resolved stellar-velocity dispersion ($\sigma_{\star}$) measurements, we study the profile of the [OIII]$\lambda$5007A e

We have found a sample of extreme emission-line galaxies (EELGs) with strong [OIII]$\lambda$5007 emission at z $\sim$ 0.5. Using broadband photometric selection and requiring small uncertainties in photometry, we searched the 14th Data Release (DR14)

We combined deep U-band and optical/near-infrared imaging, in order to select Lyman Break Galaxies (LBGs) at using U-V and colors in the Subaru Deep Field. The resulting sample of 5161 LBGs gives a UV luminosity function (LF) down to , with a steep f
