Associate Professor. 4th Mexican scholar to earn tenure in astronomy/astrophysics in the United States. Exploring more research heavy opportunities. https://jorgemoreno.org
Congratulations to Alejandro Benítez-Llambay + student/team for this interesting discovery. Also happy to report that my most recent ApJ paper is the first to cite this work. hashtag#LatinAmericanExcellence lnkd.in/g-xJ7iYz
It’s paper day. We examine MW-scale satellite quenched fractions along simulations and observations (led by F. Mercado). Enjoy! 🌀 🛰️ arxiv.org/abs/2512.06071
Our paper on galaxy ignition in the post-reionization universe has now been accepted for publication (ApJ) ⚫️🧨🌀https://arxiv.org/abs/2511.03785
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...

Our paper on the emergence of galactic discs has now been accepted for publication (MNRAS). 🔥 📦 🍊 🌀 arxiv.org/abs/2508.00991
Congratulations to David Olloqui Cortés on his first conference talk! 🇲🇽🇲🇽🇲🇽
A pleasure to co-lead a discussion with Dušan Kereš on galaxy formation and cosmic rays at this year’s Galfresca conference! 🌌 🔥
Our paper on resolved scaling relations in IllustrisTNG has now been accepted for publication (ApJ). arxiv.org/abs/2501.18687
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
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. We use IllustrisTNG to investigate resolved scaling relationship. See also our awesome spaxel leaky box analytics model! 🌌 💜https://arxiv.org/abs/2501.18687
Congratulations to our beloved children, Camila and Mateo, for graduating from university and high school. And to my beloved Viri for raising such kind and amazing young adults. We are proud of you and we love you! 👏🏽🎓♥️
It’s paper day. We find that many Milky Way analogs experienced a pickle shaped transient period throughout their formation history! 🌀 🥒 🔥 arxiv.org/abs/2506.08508
Huge thanks to NACA, the Neighborhood Assistance Corporation of America, for helping us make homeownership possible, and for fighting against racial injustice and housing discrimination in America for decades. Thank you! ♥️🖤 www.naca.com
We bought a house! 🏡 This is for our family and our ancestors! After a long history of discrimination, redlining, segregation, mass deportations, mob violence and subprime shark practices against our people, we are here today! ¡Esta es para mi gente! Homeownership is economic justice! 🏡✊🏽♥️
It’s paper day! Check out our latest paper on galactic shapes in FIREbox. Tip of the hat to Courtney Klein for leading this effort! 🔥 📦 🌌 arxiv.org/abs/2503.05612
It’s paper day! Our paper on galactic sizes has now been accepted for publication (ApJ). Tip of the hat to Francisco Mercado for leading this effort! arxiv.org/abs/2501.04084 @astronomerc.bsky.social
where I will be a panelist along with artist Marcus Zúñiga and others, as part of his exhibition From the Ground Up: Nurturing Diversity in Hostile Environments. I hope many of you are able to attend! 🖼️ 🌌 www.armoryarts.org/schedule/202...
It’s paper day! We explore resolved scaling relations with IllustrisTNG. What a weird time to be an American scientist… arxiv.org/abs/2501.18687
Thank you all for your kind birthday wishes! The saga continues… ♥️🎂💪🏾🥂
It’s paper day. We find that galactic sizes are driven by a complex interplay between virial mass and environment. arxiv.org/abs/2501.04084
In the blink of an eye, Francisco more than doubled the size of our research group. As a postdoc, he has really exceeded all expectations! 🌌 🔥
Our paper explaining elevated UV luminosity density in JWST with FIREbox has now been accepted for publication (MNRAS). 🌌 🔥 📦 arxiv.org/abs/2407.02674
Our paper on the role of galaxy interactions in triggering starbursts at the Milky Way scale has now been accepted for publication (ApJ). 🌌 🔥 arxiv.org/abs/2411.10373
A pleasure to facilitate a faculty workshop on teaching and mentoring at SBCC. Inspiring yet harrowing, given the current and forthcoming political maelstrom. 🦉🏝️♥️
Congratulations to Francisco for his first invited conference talk! 👏🏽👏🏽👏🏽
