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…
Cosmic CO and [CII] backgrounds and the fueling of star formation over 12 Gyr
Yi-Kuan Chiang
Molecular gas, modest in mass yet pivotal within the cosmic inventory, regulates baryon cycling as the immediate fuel for star formation. Across most of cosmic history, its reservo…
Thermal Sunyaev-Zel'dovich Effect in the circumgalactic medium -- II: dependence on star formation
Sanskriti Das, Nhut Truong, Yi-Kuan Chiang +1
We measure thermal Sunyaev-Zel'dovich (tSZ) Effect in the circumgalactic medium (CGM) of 2.5 million = WISEDESI galaxies out…
The SPHEREx Sky Simulator: Science Data Modeling for the First All-Sky Near-Infrared Spectral Survey
Brendan P. Crill, Yoonsoo P. Bach, Sean A. Bryan +29
We describe the SPHEREx Sky Simulator, a software tool designed to model science data for NASA's SPHEREx mission that will carry out a series of all-sky spectrophotometric surveys…
ODIN: Identifying Protoclusters and Cosmic Filaments Traced by Ly-emitting Galaxies
Vandana Ramakrishnan, Kyoung-Soo Lee, Maria Celeste Artale +22
To understand the formation and evolution of massive cosmic structures, studying them at high redshift, in the epoch when they formed the majority of their mass is essential. The O…
