Chasing Cosmic Reionization: An Extremely Faint Highly Magnified Source at with high

Sofía Rojas-Ruiz, Matteo Messa, Eros Vanzella +5

We present JWST NIRSpec IFU spectroscopic measurements of one of the faintest (M) known ionizing sources at , dubbed Small And Lensed Source Arc, SALSA. This s…

First-star imprints in a metal-poor galaxy overdensity near the end of reionization

Zihao Li, Koki Kakiichi, Lise Christensen +24

The first generation of stars, known as Population III (Pop III), formed from primordial gas consisting solely of hydrogen and helium and is believed to have emerged only a few hun…

TDCOSMO XXV: Measuring H0 to 6.5% precision with quasar strong lensing and maximally flexible mass-sheet dynamics

William Sheu, Tommaso Treu, Martin Millon +16

We present a blind time-delay cosmography measurement of the Hubble-Lemaître constant based on the quadruply imaged quasar SDSSJ1433+6007. Our analysis combines deep Hubble S…

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…

Shedding the envelope: JWST reveals a kiloparsec-scale [OIII]-weak Balmer shell around a z=7.64 quasar

Julien Wolf, Eduardo Bañados, Xiaohui Fan +25

Luminous quasars at the redshift frontier z>7 serve as stringent probes of super-massive black hole formation and they are thought to undergo much of their growth obscured by dense…
