The DESI One-Percent survey: exploring the Halo Occupation Distribution of Emission Line Galaxies with AbacusSummit simulations [PDF]

Journal of Cosmology and Astroparticle Physics, 2023
The One-Percent survey of the Dark Energy Spectroscopic Instrument collected ∼ 270k emission line galaxies (ELGs) at 0.8 < z < 1.6. The high completeness of the sample allowed the clustering to be measured down to scales never probed before, 0.04 Mpc/h ...

Characterizing Extreme Emission-line Galaxies. I. A Four-zone Ionization Model for Very High-ionization Emission [PDF]

Astrophysical Journal, 2021
Stellar population models produce radiation fields that ionize oxygen up to O+2, defining the limit of standard H ii region models (54.4 eV). The four-zone model has little to no effect on the measured total nebular abundances, but does change the ...
