Charting the expansion of the Universe from z∼0 to z∼14 with HII galaxies

R. Chávez, R. Terlevich, A. L. González-Morán +14

The authors construct an updated Hubble diagram using 243 giant H II regions and H II galaxies from redshift 0 to ~14, applying the L(Hβ)–σ relation to derive cosmological paramete…

A flux-limited sample of dusty star-forming galaxies from the Atacama Cosmology Telescope: physical properties and the case for multiplicity

Kirsten R. Hall, Jake Hassan, Richard M. Feder +3

We report the modeling of the millimeter and far-infrared spectral energy distributions of 71 dusty star-forming galaxies (DSFGs) selected by the Atacama Cosmology Telescope (ACT)…
