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…
