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.…

Ultra High-Redshift or Closer-by, Dust-Obscured Galaxies? Deciphering the Nature of Faint, Previously Missed F200W-Dropouts in CEERS

G. Gandolfi, G. Rodighiero, L. Bisigello +42

The James Webb Space Telescope (JWST) is revolutionizing our understanding of the Universe by unveiling faint, near-infrared dropouts previously beyond our reach, ranging from exce…

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)…

The ionizing photon production efficiency of star-forming galaxies at

M. Llerena, L. Pentericci, L. Napolitano +27

Investigating the ionizing emission of star-forming galaxies is critical to understanding their contribution to reionization and their impact on the surrounding environment. The nu…

ALMA Band 3 Selection of Ultra-high Redshift Dropouts: The final challenge to ΛCDM

C. Lovell, M. Lee, A. Vijayan +10

The Lyman-break technique has been used to successfully identify high-redshift candidates in broad-band photometric data in the rest-frame optical and NIR using the dropout techniq…

Little impact of mergers and galaxy morphology on the production and escape of ionizing photons in the early Universe

S. Mascia, L. Pentericci, M. Llerena +28

Compact, star-forming galaxies with high star formation rate surface densities () are often efficient Lyman continuum (LyC) emitters at , likely as inte…
