Kinetic Mixing and the Phantom Illusion: Axion-Dilaton Quintessence in Light of DESI DR2
Michael W. Toomey, Ellie Hughes, Mikhail M. Ivanov +1
Recent results from DESI BAO analyses suggest that dark energy may not be a cosmological constant and is in fact dynamical. Furthermore, the data suggest that the equation of state…
The Compressed 3D Lyman-Alpha Forest Bispectrum
Roger de Belsunce, James M. Sullivan, Patrick McDonald
Cosmological studies of the Lyman-Alpha (Lya) forest typically constrain parameters using two-point statistics. However, higher-order statistics, such as the three-point function (…
Modeling the Cosmological Lyman- Forest at the Field Level
Roger de Belsunce, Mikhail M. Ivanov, James M. Sullivan +2
The distribution of absorption lines in the spectra of distant quasars, called the Lyman- (Ly-) forest, is a unique probe of cosmology and the intergalactic medium at high re…
High-redshift Millennium and Astrid galaxies in effective field theory at the field level
James M. Sullivan, Carolina Cuesta-Lazaro, Mikhail M. Ivanov +6
Effective Field Theory (EFT) modeling is expected to be a useful tool in the era of future higher-redshift galaxy surveys such as DESI-II and Spec-S5 due to its robust description…
Can supermassive stars form in protogalaxies due to internal Lyman-Werner feedback?
James Sullivan, Zoltan Haiman, Mihir Kulkarni +1
Population III stars are possible precursors to early massive and supermassive black holes (BHs). The presence of soft UV Lyman Werner (LW) background radiation can suppress Popula…
