Venus Observations at 40 and 90 GHz with CLASS

Sumit Dahal, Michael K. Brewer, John W. Appel +30

Using the Cosmology Large Angular Scale Surveyor, we measure the disk-averaged absolute Venus brightness temperature to be 432.3 2.8 K and 355.6 1.3 K in the Q and W fr…

Two-year Cosmology Large Angular Scale Surveyor (CLASS) Observations: A First Detection of Atmospheric Circular Polarization at Q Band

Matthew A. Petroff, Joseph R. Eimer, Kathleen Harrington +27

The Earth's magnetic field induces Zeeman splitting of the magnetic dipole transitions of molecular oxygen in the atmosphere, which produces polarized emission in the millimeter-wa…
