Spectral response of SPHEREx
Howard Hui, Jamie Bock, Samuel Condon +31
The Spectro Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) is conducting the first all-sky near infrared spectral survey spanning 0.…
Mapping Galactic Dust Emission and Extinction with HI, HII, and H
Yun-Ting Cheng, Brandon S. Hensley, Tzu-Ching Chang +1
Neutral hydrogen (HI) emission closely traces the dust column density at high Galactic latitudes and is thus a powerful tool for predicting dust extinction. However, the relation b…
Bayesian Multi-line Intensity Mapping
Yun-Ting Cheng, Kailai Wang, Benjamin D. Wandelt +2
Line intensity mapping (LIM) has emerged as a promising tool for probing the 3D large-scale structure through the aggregate emission of spectral lines. The presence of interloper l…
Is the Radio Source Dipole from NVSS Consistent with the CMB and CDM?
Yun-Ting Cheng, Tzu-Ching Chang, Adam Lidz
The dipole moment in the angular distribution of the cosmic microwave background (CMB) is thought to originate from the Doppler effect and our motion relative to the CMB frame. Obs…
Data-driven Cosmology from Three-dimensional Light Cones
Yun-Ting Cheng, Benjamin D. Wandelt, Tzu-Ching Chang +1
We present a data-driven technique to analyze multifrequency images from upcoming cosmological surveys mapping large sky area. Using full information from the data at the two-point…
Near-infrared Extragalactic Background Light Fluctuations on Nonlinear Scales
Yun-Ting Cheng, James J. Bock
Several fluctuation studies on the near-infrared extragalactic background light (EBL) find an excess power at tens of arcminute scales (). Emission from the intra-hal…
Cosmic Near-infrared Background Tomography with SPHEREx Using Galaxy Cross-correlations
Yun-Ting Cheng, Tzu-Ching Chang
The extragalactic background light (EBL) consists of integrated light from all sources of emission throughout the history of the universe. At near-infrared wavelengths, the EBL is…
Probing Intra-Halo Light with Galaxy Stacking in CIBER Images
Yun-Ting Cheng, Toshiaki Arai, Priyadarshini Bangale +13
We study the stellar halos of galaxies with stellar masses spanning to (approximately galaxies at this redsh…
Superresolution Reconstruction of Severely Undersampled Point-spread Functions Using Point-source Stacking and Deconvolution
Teresa Symons, Michael Zemcov, James Bock +4
Point-spread function (PSF) estimation in spatially undersampled images is challenging because large pixels average fine-scale spatial information. This is problematic when fine-re…
Probing Cosmic Reionization and Molecular Gas Growth with TIME
Guochao Sun, Tzu-Ching Chang, Bade D. Uzgil +23
Line intensity mapping (LIM) provides a unique and powerful means to probe cosmic structures by measuring the aggregate line emission from all galaxies across redshift. The method…
Phase-Space Spectral Line De-confusion in Intensity Mapping
Yun-Ting Cheng, Tzu-Ching Chang, James J. Bock
Line intensity mapping (LIM) is a promising tool to efficiently probe the three-dimensional large-scale structure by mapping the aggregate emission of a spectral line from all sour…
Tomography of the Cosmic Dawn and Reionization Eras with Multiple Tracers
Tzu-Ching Chang, Angus Beane, Olivier Dore +41
The Cosmic Dawn and Reionization epochs remain a fundamental but challenging frontier of astrophysics and cosmology. We advocate a large-scale, multi-tracer approach to develop a c…
Optimally Mapping Large-Scale Structures with Luminous Sources
Yun-Ting Cheng, Roland de Putter, Tzu-Ching Chang +1
Intensity mapping has emerged as a promising tool to probe the three-dimensional structure of the universe. The traditional approach of galaxy redshift surveys is based on individu…
Line-Intensity Mapping: 2017 Status Report
Ely D. Kovetz, Marco P. Viero, Adam Lidz +45
Following the first two annual intensity mapping workshops at Stanford in March 2016 and Johns Hopkins in June 2017, we report on the recent advances in theory, instrumentation and…
A Foreground Masking Strategy for [CII] Intensity Mapping Experiments Using Galaxies Selected by Stellar Mass and Redshift
Guochao Sun, Lorenzo Moncelsi, Marco P. Viero +11
Intensity mapping provides a unique means to probe the epoch of reionization (EoR), when the neutral intergalactic medium was ionized by the energetic photons emitted from the firs…
Spectral Line De-confusion in an Intensity Mapping Survey
Yun-Ting Cheng, Tzu-Ching Chang, James Bock +2
Spectral line intensity mapping has been proposed as a promising tool to efficiently probe the cosmic reionization and the large-scale structure. Without detecting individual sourc…
