A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): JWST Discovers an Overdensity around a Metal Absorption-selected Galaxy at
Yunjing Wu, Feige Wang, Zheng Cai +27
The launch of opens a new window for studying the connection between metal-line absorbers and galaxies at the end of the Epoch of Reionization (EoR). Previous studies…
Circumgalactic Ly emission around submillimeter-bright galaxies with different quasar contributions
Vale González Lobos, Fabrizio Arrigoni Battaia, Seok-Jun Chang +6
We present VLT/MUSE observations targeting the extended Lyman- (Ly) emission of five high-redshift (3-4) submillimeter galaxies (SMGs) with increasing quasar (QSO) rad…
XQR-30: Black Hole Masses and Accretion Rates of 42 z>6 Quasars
C. Mazzucchelli, M. Bischetti, V. D'Odorico +19
We present bolometric luminosities, black hole masses and Eddington ratios for 42 luminous quasars at z>6 using high signal-to-noise ratio VLT/X-Shooter spectra, acquired in the en…
A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): JWST Reveals a Filamentary Structure around a z=6.61 Quasar
Feige Wang, Jinyi Yang, Joseph F. Hennawi +56
We present the first results from the JWST ASPIRE program (A SPectroscopic survey of biased halos In the Reionization Era). This program represents an imaging and spectroscopic sur…
A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): A First Look at the Rest-frame Optical Spectra of Quasars Using JWST
Jinyi Yang, Feige Wang, Xiaohui Fan +53
Studies of rest-frame optical emission in quasars at have historically been limited by the wavelengths accessible by ground-based telescopes. The James Webb Space Telescope (…
Examining the Decline in the C IV Content of the Universe over 4.3 < z < 6.3 using the E-XQR-30 Sample
Rebecca L. Davies, Emma Ryan-Weber, Valentina D'Odorico +12
Intervening CIV absorbers are key tracers of metal-enriched gas in galaxy halos over cosmic time. Previous studies suggest that the CIV cosmic mass density () decrease…
A comprehensive view of the interstellar medium in a quasar host galaxy at z~6.4
Roberto Decarli, Antonio Pensabene, Tanio Diaz-Santos +11
Characterizing the physical conditions (density, temperature, ionization state, metallicity, etc) of the interstellar medium is critical to our understanding of the formation and e…
The fraction and kinematics of broad absorption line quasars across cosmic time
Manuela Bischetti, Fabrizio Fiore, Chiara Feruglio +17
Luminous quasars are powerful targets to investigate the role of feedback from supermassive black-holes (BHs) in regulating the growth phases of BHs themselves and of their host ga…
