Bipolar Outflows out to 10~kpc for Massive Galaxies at Redshift
Yucheng Guo, Roland Bacon, Nicolas F. Bouché +15
Galactic outflows are believed to play a critical role in the evolution of galaxies by regulating their mass build-up and star formation. Theoretical models assumes bipolar shapes…
Spatially-resolved Spectroscopic Analysis of Ly Haloes: Radial Evolution of the Ly Line Profile out to 60 kpc
Yucheng Guo, Roland Bacon, Lutz Wisotzki +11
The extended Ly haloes (LAHs) have been found to be prevalent around high-redshift star-forming galaxies. However, the origin of the LAHs is still a subject of debate. Spatially…
Median Surface Brightness Profiles of Lyman- Haloes in the MUSE Extremely Deep Field
Yucheng Guo, Roland Bacon, Lutz Wisotzki +10
We present the median surface brightness profiles of diffuse Ly haloes (LAHs) around star-forming galaxies by stacking 155 spectroscopically confirmed Ly emitters (LAEs) at 3…
Large-scale excess HI absorption around galaxies detected in a background galaxy spectrum in the MUSE eXtremely Deep Field
Jorryt Matthee, Christopher Golling, Ruari Mackenzie +12
Observationally mapping the relation between galaxies and the intergalactic medium (IGM) is of key interest for studies of cosmic reionization. Diffuse hydrogen gas has typically b…
SILVERRUSH. XIII. A Catalog of 20,567 Ly Emitters at Identified in the Full-depth Data of the Subaru/HSC-SSP and CHORUS Surveys
Satoshi Kikuta, Masami Ouchi, Takatoshi Shibuya +13
We present 20,567 Ly emitters (LAEs) at that are photometrically identified by the SILVERRUSH program in a large survey area up to 25 deg with deep images of fiv…
EMPRESS. XIV. Strong High Ionization Lines of Young Galaxies at : Ionizing Spectra Consistent with the Intermediate Mass Black Holes with
Shun Hatano, Masami Ouchi, Hiroya Umeda +16
We present ionizing spectra estimated at 13.6--100 eV for ten dwarf galaxies with strong high ionization lines of He {\sc {ii}}4686 and [Ne {\sc{v}}]3426 ([Ne {\sc{iv}}]24…
EMPRESS. XIII. Chemical Enrichments of Young Galaxies Near and Far at z ~ 0 and 4-10: Fe/O, Ar/O, S/O, and N/O Measurements with Chemical Evolution Model Comparisons
Kuria Watanabe, Masami Ouchi, Kimihiko Nakajima +14
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\si…
JWST/NIRSpec Measurements of Extremely Low Metallicities in High Equivalent Width Lyman- Emitters
Michael V. Maseda, Zach Lewis, Jorryt Matthee +19
Deep VLT/MUSE optical integral field spectroscopy has recently revealed an abundant population of ultra-faint galaxies (; 0.01 ) at 2.96.7 due…
EMPRESS. XII. Statistics on the Dynamics and Gas Mass Fraction of Extremely-Metal Poor Galaxies
Yi Xu, Masami Ouchi, Yuki Isobe +49
We present demography of the dynamics and gas-mass fraction of 33 extremely metal-poor galaxies (EMPGs) with metallicities of and low stellar masses of $10^4-…
EMPRESS. XI. SDSS and JWST Search for Local and z~4-5 Extremely Metal-Poor Galaxies (EMPGs): Clustering and Chemical Properties of Local EMPGs
Moka Nishigaki, Masami Ouchi, Kimihiko Nakajima +16
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…
Clustering dependence on Lyman- luminosity from MUSE surveys at
Y. Herrero Alonso, T. Miyaji, L. Wisotzki +6
[Abbreviated] We investigate the dependence of Lyman- emitter (LAE) clustering on Lyman- luminosity. We use 1030 LAEs from the MUSE-Wide survey, 679 LAEs from MUSE-Deep, and…
