Super-Eddington accretion boosts predicted LISA detections of high-redshift black hole binaries to ~64 per year while dropping ET detections to ~4 per year, compared to ~32 and ~64 under Eddington-limited growth.
JADES DR5 delivers 2081 z_phot > 8 galaxy candidates with UV slope trends, morphological evidence of clumpy growth, and improved photo-z methods tested on a spectroscopic subsample.
An evolving star formation efficiency f_*(z) = 10^{0.13z-3.5} plus SNII-driven dust processes explain the UV LF at z=5-13, with galaxies retaining ~0.15% dust-to-stellar mass at z>9 and ALMA z=5-7 observations not representing the average population.

Exploring the interplay between star formation efficiency and dust in regulating the UV luminosity of early systems in the JWST and ALMA era
An evolving star formation efficiency f_*(z) = 10^{0.13z-3.5} plus SNII-driven dust processes explain the UV LF at z=5-13, with galaxies retaining ~0.15% dust-to-stellar mass at z>9 and ALMA z=5-7 observations not representing the average population.
