Euclid Quick Data Release (Q1): Hunting for luminous z > 6 galaxies in the Euclid Deep Fields -- forecasts and first bright detections

Euclid Collaboration, N. Allen, P. A. Oesch +309

The evolution of the rest-frame ultraviolet luminosity function (UV LF) is a powerful probe of early star formation and stellar mass build-up. At z > 6, its bright end (MUV < -21)…

Updated dark pixel fraction constraints on reionization's end from the Lyman-series forests of XQR-30

Frederick B. Davies, Sarah E. I. Bosman, Valentina D'Odorico +16

The fraction of "dark pixels" in the Ly and other Lyman-series forests at provides a powerful constraint on the end of the reionization process. Any spectral region…

Euclid: Discovery of bright Lyman-break galaxies in UltraVISTA and Euclid COSMOS

R. G. Varadaraj, R. A. A. Bowler, M. J. Jarvis +163

We present a search for Lyman-break galaxies using the near-infrared UltraVISTA survey in the COSMOS field, reaching depths in of 26.2. W…

Extreme Galaxy-scale Outflows Are Frequent among Luminous Early Quasars

Weizhe Liu, Xiaohui Fan, Huan Li +23

The existence of abundant post-starburst/quiescent galaxies just 1-2 Gyrs after the Big Bang challenges our current paradigm of galaxy evolution. Cosmological simulations sug…

First constraints on the local ionization topology in front of two quasars at z ~ 7.5

Timo Kist, Joseph F. Hennawi, Frederick B. Davies +10

Thus far, Lyman- damping wings towards quasars have been used to probe the \textit{global} ionization state of the foreground intergalactic medium (IGM). A new parameterization…
