ASPIRE: The Environments and Dark Matter Halos of Luminous Quasars in the Epoch of Reionization
Feige Wang, Jaclyn B. Champagne, Jiamu Huang +42
We present a systematic study of the environments of 25 luminous quasars at from the ASPIRE program. Using JWST/NIRCam WFSS data, we identified 487 galaxies at $5.3 \less…
Probing Direct Contributions of Galaxies and AGN to Cosmic Reionization in a Quasar Field J0226+0302 with JWST NIRCam and NIRSpec
Xiangyu Jin, Jinyi Yang, Feige Wang +19
We present JWST Cycle 2 NIRCam and NIRSpec observations in a quasar field J0226+0302 at z=6.5412 to probe the direct connections between the intergalactic medium (IGM), galaxies, a…
CO(7-6) and [C I](2-1) survey in z > 6 quasars
Fuxiang Xu, Roberto Decarli, Ran Wang +13
High-redshift () quasars trace the earliest supermassive black holes and intense star formation, offering key laboratories for black hole-galaxy evolution at cosmic dawn…
Detection of an Extended Ly Halo around a Broad Absorption Line Quasar with the Keck Cosmic Web Imager
Raymond P. Remigio, Aaron J. Barth, Feige Wang +6
We present the first results from a program searching for extended Ly halos around high redshift () quasars using the red channel of the Keck Cosmic Web Imager…
A Close Quasar Pair in a Massive Galaxy Merger at
Minghao Yue, Xiaohui Fan, Anna-Christina Eilers +3
Close quasar pairs are rare products of galaxy mergers in which both supermassive black holes (SMBHs) are actively accreting, offering strong constraints on merger-driven active ga…
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…
