I wrote a manuscript on galaxy ignition in the post-reionization universe. A bittersweet milestone. This is my 70th paper and I’ve reached 4000 citations. But it’s also four months without my beloved father, to whom I dedicate this work. arxiv.org/abs/2511.03785 ♥️

Igniting galaxy formation in the post-reionization universe

It is widely believed that the ultraviolet background produced during the epoch of reionization conspires against the formation of low-mass galaxies. Indeed, this mechanism is often invoked as a solut...

It’s paper day. We find that the emergence of disk galaxies is connected to the bursty-to-steady star formation transition and the deepening of the gravitational potential well. 🌌 🔥 📦 arxiv.org/abs/2508.00991

Jorge Moreno @jorgitomoreno.bsky.social · 23/06/2025

It’s LSST/Rubin-relevant paper day. We investigate how not being able to detect faint stellar halos biases our understanding of ultrafaint galaxies, thus limiting their applicability to constrain galaxy formation and dark matter physics. 🌌 🔥https://arxiv.org/abs/2506.15785

It’s paper day. We compare the kinematic-age structure of FIRE-2 galaxies to observations, agreeing with LG + PHANGs, but not the MW (a dynamically cold outlier). 🌀 🌌 🔥 arxiv.org/abs/2506.11840

It’s paper day. Our new FIREbox-HR simulation explains elevated UV luminosity density in JWST. With FIRE physics, we predict a non-evolving, weakly-mass dependent star formation efficiency, alleviating the need to invoke weird baryonic physics or non-LCDM cosmology. 🔥 📦 🌌 arxiv.org/abs/2407.02674
