ALMA and JWST Imaging of Quasars: No Spatial Position Offset Observed Between Quasars and Their Host Galaxies

Aurora Wilde, Marcel Neeleman, Romain Meyer +4

We present a study determining the spatial offset between the position of the supermassive black hole (as traced through their broad line regions) and the host galaxy in six $z > 6…

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…

Discovery and characterization of 25 new quasars at 4.6 < z < 6.9 from wide-field multi-band surveys

Silvia Belladitta, Eduardo Bañados, Zhang-Liang Xie +18

Luminous quasars at provide key insights into the early Universe. Their rarity necessitates wide-field multi-band surveys to efficiently separate them from the main astrophys…

JWST ASPIRE: How Did Galaxies Complete Reionization? Evidence for Excess IGM Transmission around Emitters during Reionization

Koki Kakiichi, Xiangyu Jin, Feige Wang +23

The spatial correlation between galaxies and the Ly forest provides insights into how galaxies reionized the Universe. Here, we present initial results on the spatial cross-corr…
