Early Supermassive Black Holes and Little Red Dots Require Free-Fall Growth
Junehyoung Jeon, Volker Bromm, Michael Boylan-Kolchin +1
Supermassive black holes/active galactic nuclei (SMBHs/AGN), forming only a few hundred million years after the Big Bang as observed with the James Webb Space Telescope (JWST), cha…
Searching for Population III stars with line intensity mapping cross-correlations
Sahil Hegde, Guochao Sun, Julian B. Muñoz +1
Decades of searches for Population III stars in individual galaxies have yielded a few potential candidates, but a statistically robust characterization of the demographics of the…
Resolving galaxy formation in the early Universe with BonFIRE and CampFIRE
Jenna Samuel, Michael Boylan-Kolchin, Robert Feldmann +16
The abundance and rapid growth of galaxies at cosmic dawn revealed by the James Webb Space Telescope challenges models of galaxy formation, motivating new simulations to uncover th…
Constraining bursty star formation histories with galaxy UV and H luminosity functions and clustering
Guochao Sun, Julian B. Muñoz, Jordan Mirocha +1
The observed prevalence of galaxies exhibiting bursty star formation histories (SFHs) at has created new challenges and opportunities for understanding their formation…
A Generative Modeling Approach to Reconstructing 21-cm Tomographic Data
Nashwan Sabti, Ram Reddy, Julian B. Muñoz +2
Analyses of the cosmic 21-cm signal are hampered by astrophysical foregrounds that are far stronger than the signal itself. These foregrounds, typically confined to a wedge-shaped…
The First Billion Years in Seconds: An Effective Model for the 21-cm Signal with Population III Stars
Hector Afonso G. Cruz, Julian B. Munoz, Nashwan Sabti +1
Observations of the 21-cm signal are opening a window to the cosmic-dawn epoch, when the first stars formed. These observations are usually interpreted with semi-numerical or hydro…
Warm Hawking Relics From Primordial Black Hole Domination
Christopher J. Shallue, Julian B. Muñoz, Gordan Z. Krnjaic
We study the cosmological impact of warm, dark-sector relic particles produced as Hawking radiation in a primordial-black-hole-dominated universe before big bang nucleosynthesis. I…
