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…
