Searching for Population III stars with line intensity mapping cross-correlations
Sahil Hegde, Guochao Sun, Julian B. Muñoz +1
Decades of searches for Population III stars in individual galaxies have yielded a few potential candidates, but a statistically robust characterization of the demographics of the…
TIME Commissioning Observations: II. On-sky Characterization and the 2D Map Data Processing Pipeline
Benjamin J. Vaughan, Abigail T. Crites, Dongwoo T. Chung +24
The Tomographic Ionized-carbon Mapping Experiment (TIME) is a line intensity mapping (LIM) instrument that is designed to observe the power spectrum of the [CII] ~m emissi…
Development of a planar cable-driven parallel robot for submillimeter and terahertz beam mapping measurements
Evan C. Mayer, Ian N. Lowe, Daniel P. Marrone +20
The spatial sensitivity pattern of millimeter-wavelength receivers is an important diagnostic of performance and is affected by the alignment of coupling optics. Characterization c…
LIMFAST. IV. Learning High-Redshift Galaxy Formation from Multiline Intensity Mapping with Implicit Likelihood Inference
Guochao Sun, Tri Nguyen, Claude-André Faucher-Giguère +5
By opening up new avenues to statistically constrain astrophysics and cosmology with large-scale structure observations, the line intensity mapping (LIM) technique calls for novel…
TIME Commissioning Observations: I. Mapping Dust and Molecular Gas in the Sgr A Molecular Cloud Complex at the Galactic Center
Selina F. Yang, Sophie M. McAtee, Benjamin J. Vaughan +24
We present the processing of an observation of Sagittarius A (Sgr A) with the Tomographic Ionized-carbon Mapping Experiment (TIME), part of the 2021-2022 commissioning run to verif…
Constraining bursty star formation histories with galaxy UV and H luminosity functions and clustering
Guochao Sun, Julian B. Muñoz, Jordan Mirocha +1
The observed prevalence of galaxies exhibiting bursty star formation histories (SFHs) at has created new challenges and opportunities for understanding their formation…
