Optimization of Antenna Performance for Global 21-cm Observations and Verification Using Scaled Copies
O. A. Restrepo, F. I. Lucero, G. Chaparro +5
The sky-averaged cosmological 21 cm signal can improve our understanding of the evolution of the early Universe from the Dark Age to the end of the Epoch of Reionization. Although…
Cosmology Large Angular Scale Surveyor (CLASS): 90 GHz Telescope Pointing, Beam Profile, Window Function, and Polarization Performance
Rahul Datta, Michael K. Brewer, Jullianna Denes Couto +31
The Cosmology Large Angular Scale Surveyor (CLASS) is a telescope array that observes the cosmic microwave background (CMB) over ~75% of the sky from the Atacama Desert, Chile, at…

Calibration of Transition-edge Sensor (TES) Bolometer Arrays with Application to CLASS
John W. Appel, Charles L. Bennett, Michael K. Brewer +24
The current and future cosmic microwave background (CMB) experiments fielding kilo-pixel arrays of transition-edge sensor (TES) bolometers require accurate and robust gain calibrat…
The Atacama Cosmology Telescope: Modeling Bulk Atmospheric Motion
Thomas W. Morris, Ricardo Bustos, Erminia Calabrese +17
Fluctuating atmospheric emission is a dominant source of noise for ground-based millimeter-wave observations of the CMB temperature anisotropy at angular scales $\gtrsim 0.5^{\circ…
