An Enhanced Catalog of Gaia DR3 Galaxy Candidates with Spectroscopic and Machine-Learning Photometric Redshifts
Junghyun Hwang, Ho Seong Hwang
The paper presents an updated all‑sky galaxy catalog based on Gaia DR3, adding spectroscopic redshifts where available and machine‑learning photometric redshifts for the rest, usin…
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…
Dynamical Test of Cosmic Acceleration: -nearest Neighbor Cross Correlation of Cosmic Microwave Background and Cosmic Infrared Background
Dongkok Kim, Donghui Jeong, Yi-Kuan Chiang +1
The physical origin of cosmic acceleration remains one of the central questions in modern cosmology. The integrated Sachs-Wolfe (ISW) and Rees-Sciama (RS) effects, which arise from…
Ongoing Morphological Transformation from Elliptical to Spiral Galaxies Induced by Gas Accretion from Neighboring Galaxies
Gene Yun, Sang Hyeok Im, Ho Seong Hwang +2
We present results from spectroscopic observations of three interacting galaxy systems, each associated with a primary galaxy - VCC 1748, SDSS J1106, and 2MASX J0834 - which have b…
Constructing a Mock Galaxy Catalog for the All-sky SPECtroscopic Survey of Nearby Galaxies (A-SPEC) Using the Machine-assisted Semi-Simulation Model
Dongkok Kim, Yongseok Jo, Ho Seong Hwang +26
We present a methodology for constructing a mock galaxy catalog for the All-sky SPECtroscopic survey of nearby galaxies (A-SPEC) using the Machine-assisted Semi-Simulation Model. T…
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…
