Infrared emission from quasar host galaxies: a direct estimate of dust physical properties
M. Costa, R. Decarli, F. Pozzi +6
Quasars at the dawn of Cosmic Time () are fundamental probes to investigate the early co-evolution of supermassive black holes and their host galaxy. Nevertheless, their infra…
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…
SHELLQs-JWST perspective on the intrinsic mass relation between supermassive black holes and their host galaxies at z > 6
John Silverman, Junyao Li, Xuheng Ding +36
The relation between the masses of supermassive black holes (SMBHs) and their host galaxies encodes information on their mode of growth, especially at the earliest epochs. The Jame…
Beneath the Surface: >85% of z>5.9 QSOs in Massive Host Galaxies are UV-Faint
R. J. Bouwens, E. Banados, R. Decarli +20
We use [CII] observations of a large quasi-stellar object (QSO) sample to segregate sources by host galaxy mass, aiming to identify those in the most massive hosts. [CII] luminosit…
A 13-Billion-Year View of Galaxy Growth: Metallicity Gradient Evolution from the Local Universe to with JWST and Archival Surveys
Zihao Li, Zheng Cai, Xin Wang +25
The galaxy gas-phase metallicity gradients have been extensively studied over the past four decades, both in the local and high-redshift universe, as they trace the baryon cycle an…
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…
A Cosmic Miracle: A Remarkably Luminous Galaxy at Confirmed with JWST
Rohan P. Naidu, Pascal A. Oesch, Gabriel Brammer +43
JWST has revealed a stunning population of bright galaxies at surprisingly early epochs, , where few such sources were expected. Here we present the most distant example of t…
Insights on Metal Enrichment and Environmental Effect at with JWST ASPIRE/EIGER and Chemical Evolution Model
Zihao Li, Koki Kakiichi, Lise Christensen +15
We present the mass-metallicity relation (MZR) for a parent sample of 604 galaxies at with \OIII\ doublets detected, using the deep JWST/NIRCam wide field slitless sp…
Kiloparsec-Scale Alignment of a Radio Jet with Cool Gas and Dust in a z~6 Quasar
Fabian Walter, Eduardo Banados, Chris Carilli +11
We present high-angular resolution (0.068", ~400pc) ALMA imaging of the [CII] line and dust continuum emission of PSO J352.4034-15.3373, a radio-loud quasar at z=5.83. The observat…
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…
ALMA 360 pc high-frequency observations reveal warm dust in the center of a quasar
Romain A. Meyer, Fabian Walter, Fabio Di Mascia +3
The temperature of the cold dust in z>6 galaxies is a potential tracer of Active Galactic Nucleus (AGN) and stellar feedback, and is the dominant source of uncertainty in inferring…
