Widespread Extended [CII] Emission in High-Redshift Galaxies: Insights from the FIRE-2 Cosmological Zoom-in Simulations
Lun-Jun Liu, Guochao Sun, Andreas L. Faisst +3
Recent ALMA observations reveal diffuse [CII] emission ("[CII] halos") extending to kpc in galaxies at . These measurements provide new insights into high-red…
Relatively Fast and Reasonably Furious: Evidence for Increased Burstiness in Smaller Halos at Cosmic Dawn
Julian B. Muñoz, John Chisholm, Guochao Sun +7
We introduce an effective framework to model star-formation burstiness and use it to jointly fit galaxy UV luminosity functions (UVLFs), clustering, and H/UV ratios, providing…
Do cosmological simulations reproduce the [OIII] 88 m line emission and properties of JWST-discovered galaxies at ?
Shengqi Yang, Adam Lidz, Hui Li +3
Recent ALMA observations of the [OIII] 88 m line provide spectroscopic confirmation of two JWST photometric candidates, GS-z14 and GHZ2, at and , respectively.…
Fuzzy Dark Matter Constraints from the Hubble Frontier Fields
Jackson Sipple, Adam Lidz, Daniel Grin +1
In fuzzy dark matter (FDM) cosmologies, the dark matter consists of ultralight bosons ( eV). The astrophysically large de Broglie wavelengths of such particles h…
Signatures of high-redshift galactic outflows in the thermal Sunyaev Zel'dovich effect
Guochao Sun, Steven R. Furlanetto, Adam Lidz
Anisotropies of the Sunyaev Zel'dovich (SZ) effect serve as a powerful probe of the thermal history of the universe. At high redshift, hot galactic outflows driven by supernovae (S…
