A Super-Eddington, Lensing-Magnified Quasar at observed with JWST

Katherine Panebianco, Minghao Yue, Anna-Christina Eilers +4

We present JWST/NIRCam F070W and F480M imaging for a quasar at , J0025-0145, which is magnified by a foreground lensing galaxy. Existing Hubble Space Telescope (HST) imag…

Quasar clustering and duty cycle measurements at with the Gaia-unWISE Catalog

Mariona Giner Mascarell, Anna-Christina Eilers, Kate Storey-Fisher

We measure the two-point correlation function of a uniformly selected, all-sky sample of 1.3 million quasars with magnitudes from the Gaia--unWISE Quasar Catalog…

A close look at the black hole masses and hot dusty toruses of the first quasars with MIRI-MRS

Sarah E. I. Bosman, Javier Álvarez-Márquez, Frederick B. Davies +29

The presence of supermassive black holes (SMBHs, ) at remains a puzzle. While their existence appears to require exotic formation or growth proce…

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…

A first look at quasar-galaxy clustering at

Jan-Torge Schindler, Joseph F. Hennawi, Frederick B. Davies +8

We present JWST observations of the environments surrounding two high-redshift quasars, J02520503 at and J10072115 at , which enable the first constraints…

EIGER VIII: First stars signatures in the connection between OI absorption and Galaxies in the Epoch of Reionization

Jack Higginson, Rongmon Bordoloi, Robert A. Simcoe +8

We investigate the association between galaxies and neutral OI absorption systems at z~6, which trace metal-enriched gas during the epoch of reionization. We identify 40 galaxies a…
