ODIN: Characterizing the Three-dimensional Structure of Two Protocluster Complexes at

Vandana Ramakrishnan, Ashley Ortiz, Byeongha Moon +52

We present a detailed study of the 3D morphology of two extended associations of multiple protoclusters at . These protocluster 'complexes', designated COSMOS-z3.1-A and COS…

ODIN: Clustering Properties of Ly Blobs at 2.4 and 3.1

Byeongha Moon, Yujin Yang, Eric Gawiser +18

Spatially extended Ly nebulae, known as Ly blobs (LABs), are a rare population at that are thought to trace proto-groups or the progenitors of massive galaxies in t…

Golden and Silver Dark Sirens for precise H0 measurement with HETDEX

Yixuan Dang, Ish Gupta, Robin Ciardullo +12

Gravitational waves (GWs) from compact binary coalescences are standard sirens that provide a direct measure of the source's luminosity distance, enabling an independent measuremen…

Lyα Intensity Mapping in HETDEX: Galaxy-Lyα Intensity Cross-Power Spectrum

Maja Lujan Niemeyer, Eiichiro Komatsu, José Luis Bernal +18

We present a measurement of the Lyman- (Ly) intensity mapping power spectrum from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). We measure the cross-power spe…

Extragalactic Planetary Nebulae (xPNe). Determining Distances out to 100 Mpc and the Renaissance of the PN Luminosity Function Method

Magda Arnaboldi, Ortwin Gerhard, Martin Roth +9

The discrepancy of the Hubble parameter H0 as measured from the cosmic microwave background versus that found from traditional distance ladder measurements has produced considerabl…

ODIN: A New Lyman Alpha Blob Selection Method, Sample, and Statistical Analysis at

Byeongha Moon, Yujin Yang, Kyoung-Soo Lee +26

Ly blobs (LABs) are large, spatially extended Ly-emitting objects whose nature remains unclear. Their statistical properties such as number densities and luminosity functio…
