Early galaxy formation and its large-scale effects
Galaxy formation is at the heart of our understanding of cosmic evolution. Although there is a
consensus that galaxies emerged from the expanding matter background by gravitational …

Are the ultra-high-redshift galaxies at z > 10 surprising in the context of standard galaxy formation models?
ABSTRACT A substantial number of ultra-high redshift (8≲ z≲ 17) galaxy candidates have
been detected with JWST, posing the question: Are these observational results surprising in …

The prevalence of galaxy overdensities around UV-luminous Lyman 𝛼 emitters in the Epoch of Reionization
Before the end of the Epoch of Reionization, the Hydrogen in the Universe was
predominantly neutral. This leads to a strong attenuation of Ly α lines of z≳ 6 galaxies in the …
