Extremely Metal-Poor Representatives Explored by the Subaru Survey (EMPRESS). I. A Successful Machine Learning Selection of Metal-Poor Galaxies and the Discovery of a Galaxy with M*<10^6 M_sun and 0.016 Z_sun
Takashi Kojima, Masami Ouchi, Michael Rauch +18
We have initiated a new survey for local extremely metal-poor galaxies (EMPGs) with Subaru/Hyper Suprime-Cam (HSC) large-area (~500 deg^2) optical images reaching a 5 sigma limit o…
A Giant Intragroup Nebula Hosting a Damped Lya Absorber at z=0.313
Hsiao-Wen Chen, Erin Boettcher, Sean D. Johnson +5
This paper reports the discovery of spatially-extended line-emitting nebula, reaching to ~100 physical kpc (pkpc) from a damped Lyα absorber (DLA) at z_DLA=0.313 along the sightlin…
CHORUS. III. Photometric and Spectroscopic Properties of Ly Blobs at
Haibin Zhang, Masami Ouchi, Ryohei Itoh +20
We report the Subaru Hyper Suprime-Cam (HSC) discovery of two Ly blobs (LABs), dubbed z70-1 and z49-1 at and respectively, that are Ly emitters with a bri…
Probing IGM accretion onto faint Lyα emitters at z~2.8
Fakhri S. Zahedy, Michael Rauch, Hsiao-Wen Chen +3
(abridged) Observing the signature of accretion from the intergalactic medium (IGM) onto galaxies at z~3 requires the detection of faint (L<<L*) galaxies embedded in a filamentary…
A metal-poor damped Ly-alpha system at redshift 6.4
Eduardo Banados, Michael Rauch, Roberto Decarli +9
We identify a strong Ly-alpha damping wing profile in the spectrum of the quasar P183+05 at z=6.4386. Given the detection of several narrow metal absorption lines at z=6.40392, the…
