A search for the first galaxies across deg of JWST imaging: new evidence for a rapid decline in star-formation activity at
D. J. McLeod, J. S. Dunlop, R. J. McLure +20
We present a new determination of the evolving galaxy UV luminosity function (LF) over the extreme redshift range , based on a wide-area search of 0.6 deg of JW…

X-Shooting ULLYSES: Massive stars at low metallicity. XIII. Putting the bi-stability jump to the test in the LMC
T. Alkousa, P. A. Crowther, J. M. Bestenlehner +10
We aim to investigate the theoretical bi-stability jump, which predicts an increase in mass-loss rates below 21 kK. We further aim to constrain the photospheric and wind parameters…

X-Shooting ULLYSES: Massive stars at low metallicity -- V. Effect of metallicity on surface abundances of O stars
F. Martins, J. -C. Bouret, D. J. Hillier +10
Massive stars rotate faster, on average, than lower mass stars. Stellar rotation triggers hydrodynamical instabilities which transport angular momentum and chemical species from th…
