Extreme Enrichment at Cosmic Dawn: Three FeII-Strong Quasars at z > 6 from the JWST Aether survey

Anniek J. Gloudemans, Emanuele Paolo Farina, Roberto Decarli +22

We present three outliers on the quasar main sequence at z>6, as revealed by JWST/NIRSpec IFU observations from the Aether survey, a program targeting ~200 quasars at cosmic dawn.…

BEES: Quasar lifetime measurements from extended rest-optical emission line nebulae at

Dominika Ďurovčíková, Anna-Christina Eilers, Yuzo Ishikawa +13

Measurements of quasar lifetimes at high redshift indicate that the earliest billion-solar-mass supermassive black holes (SMBHs) have only been active as luminous quasars for less…

An extremely metal-poor Lyman emitter candidate at revealed through absorption spectroscopy

Dominika Ďurovčíková, Anna-Christina Eilers, Robert A. Simcoe +10

We report the discovery of a Lyman emitter (LAE) candidate in the immediate foreground of the quasar PSO J158-14 at at a projected distance $\sim29\ {\rm p…

Quasar lifetime measurements from extended Ly nebulae at

Dominika Ďurovčíková, Anna-Christina Eilers, Romain A. Meyer +7

The existence of billion-solar-mass black holes hosted in luminous quasars within the first gigayear of cosmic history poses a challenge to our understanding of supermassive black…

EIGER III. JWST/NIRCam observations of the ultra-luminous high-redshift quasar J0100+2802

Anna-Christina Eilers, Robert A. Simcoe, Minghao Yue +6

We present the first rest-frame optical spectrum of a high-redshift quasar observed with JWST/NIRCam in Wide Field Slitless (WFSS) mode. The observed quasar, J0100+2802, is the mos…

A comparison of quasar emission reconstruction techniques for Lyman- and Lyman- transmission

S. E. I. Bosman, D. Ďurovčíková, F. B. Davies +1

Reconstruction techniques for intrinsic quasar continua are crucial for the precision study of Lyman- (Ly-) and Lyman- (Ly-) transmission at , where the $λ<1215…
