HETDEX: Star Formation Stochasticity Diagram of Lyman Alpha Emitting Galaxies at Cosmic Noon Confirms Three Archetypes

Nicole Firestone, Eric Gawiser, Kartheik G. Iyer +14

In this work, we aim to measure the star formation stochasticity of Lyman Alpha Emitting Galaxies (LAEs) at Cosmic Noon. We identify 270 LAEs from the HETDEX Survey in the COSMOS f…

Constraining the spatial curvature with cosmic expansion history in a cosmological model with a non-standard sound horizon

Jordan Stevens, Hasti Khoraminezhad, Shun Saito

Spatial curvature is one of the most fundamental parameters in our current concordance flat CDM model of the Universe. The goal of this work is to investigate how the constraint…
