The Physical Origin of Extreme Emission Line Galaxies at High redshifts: Strong {\sc [Oiii]} Emission Lines Produced by Obscured AGNs

Chenghao Zhu, Yuichi Harikane, Masami Ouchi +21

We present deep Subaru/FOCAS spectra for two extreme emission line galaxies (EELGs) at with strong {\sc[Oiii]}5007 emission lines, exhibiting equivalent widths (EWs) o…

A Post-Starburst Pathway for the Formation of Massive Galaxies and Black Holes at z>6

Masafusa Onoue, Xuheng Ding, John D. Silverman +45

Understanding the rapid formation of supermassive black holes (SMBHs) in the early universe requires insight into stellar mass growth in host galaxies. Here, we present NIRSpec res…

Discovery of merging twin quasars at z = 6.05

Yoshiki Matsuoka, Takuma Izumi, Masafusa Onoue +14

We report the discovery of two quasars at a redshift of = 6.05, in the process of merging. They were serendipitously discovered from the deep multi-band imaging data collected…

Merging gas-rich galaxies that harbor low-luminosity twin quasars at z = 6.05: a promising progenitor of the most luminous quasars

Takuma Izumi, Yoshiki Matsuoka, Masafusa Onoue +15

We present ALMA [CII] 158 m line and underlying far-infrared (FIR) continuum emission observations ( resolution) toward a quasar-quasar pair system recentl…
