We search for local extremely metal-poor galaxies (EMPGs), selecting photometric candidates by broadband color excess and machine-learning techniques with the SDSS photometric data. After removing stellar contaminants by shallow spectroscopy with Sei

We present ionizing spectra estimated at 13.6--100 eV for ten dwarf galaxies with strong high ionization lines of He {\sc {ii}}$\lambda$4686 and [Ne {\sc{v}}]$\lambda$3426 ([Ne {\sc{iv}}]$\lambda$2424) at $z=0$ ($z=8$) that are identified in our Keck

Maseda, Michael V., Lewis, Zach, Matthee, Jorryt, Hennawi, Joseph F., Boogaard, Leindert, Feltre, Anna, Nanayakkara, Themiya, Bacon, Roland, Barger, Amy, Brinchmann, Jarle, Franx, Marijn, Hashimoto, Takuya, Inami, Hanae, Kusakabe, Haruka, Leclercq, Floriane, Rowland, Lucie, Taylor, Anthony J., Tremonti, Christy, Urrutia, Tanya, Schaye, Joop, Simmonds, Charlotte, Vitte, Eloïse
Deep VLT/MUSE optical integral field spectroscopy has recently revealed an abundant population of ultra-faint galaxies ($M_{UV} = -$15; 0.01 $L_{\star}$) at $z=$2.9$-$6.7 due to their strong Lyman-$α$ emission. The implied Lyman-$α$ equivalent widt

We present gas-phase elemental abundance ratios of 7 local extremely metal-poor galaxies (EMPGs) including our new Keck/LRIS spectroscopy determinations together with 33 JWST $z\sim 4-10$ star-forming galaxies in the literature, and compare chemical

We present 20,567 Ly$α$ emitters (LAEs) at $z=2.2-7.3$ that are photometrically identified by the SILVERRUSH program in a large survey area up to 25 deg$^2$ with deep images of five broadband filters (grizy) and seven narrowband filters targeting Ly

We report that Ly$��$-emitting galaxies (LAEs) may not faithfully trace the cosmic web of neutral hydrogen (HI), but their distribution is likely biased depending on the viewing direction. We calculate the cross-correlation (CCF) between galaxies

We present bright [CII] 158 $��$m line detections from a strongly magnified and multiply-imaged ($��\sim20-160$) sub-$L^{*}$ ($M_{\rm UV}$ = $-19.75^{+0.55}_{-0.44}$) Lyman-break galaxy (LBG) at $z=6.0719\pm0.0004$ from the ALMA Lensing Clust

The intensity of the Cosmic UV background (UVB), coming from all sources of ionising photons such as star-forming galaxies and quasars, determines the thermal evolution and ionization state of the intergalactic medium (IGM) and is, therefore, a criti

CR7 is among the most luminous Lyman-$��$ emitters (LAEs) known at $z = 6.6$ and consists of at least three UV components that are surrounded by Lyman-$��$ (Ly$��$) emission. Previous studies have suggested that it may host an extreme ion

We present element abundance ratios and ionizing radiation of local young low-mass (~$10^{6}$ M_sun) extremely metal poor galaxies (EMPGs) with a 2% solar oxygen abundance (O/H)_sun and a high specific star-formation rate (sSFR~300 Gyr$^{-1}$), and o
