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…

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…

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…
