A Measurement of Atmospheric Circular Polarization with POLARBEAR
The Astrophysical JournalAt millimeter wavelengths, the atmospheric emission is circularly polarized owing to the Zeeman splitting of molecular oxygen by the Earth's magnetic field.

Delensing of Cosmic Microwave Background Polarization with Machine Learning
The Astrophysical Journal Supplement Series, 2023 Primordial B -mode detection is one of the main goals of next-generation cosmic microwave background (CMB) experiments. Primordial B -modes are a unique signature of primordial gravitational waves (PGWs).

Recovering Cosmic Microwave Background Polarization Signals with Machine Learning
The Astrophysical Journal, 2023 Primordial B-mode detection is one of the main goals of current and future cosmic microwave background (CMB) experiments. However, the weak B-mode signal is overshadowed by several Galactic polarized emissions, such as thermal dust emission and ...

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers
River Research and Applications, Volume 42, Issue 6, Page 1115-1141, July 2026.ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Cosmic Strings and Their Induced Non-Gaussianities in the Cosmic Microwave Background
Advances in Astronomy, 2010 Motivated by the fact that cosmological perturbations of inflationary quantum origin were born Gaussian, the search for non-Gaussianities in the cosmic microwave background (CMB) anisotropies is considered as the privileged probe of nonlinear physics in ...

Primordial circular polarization in the cosmic microwave background
Physics Letters B, 2019 Circular (“V-mode”) polarization is expected to be vanishing in the CMB, since it is not produced in Thomson scattering. However, considering that the conventional CMB anisotropies are generated via an early universe mechanism such as inflation or a ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.Abstract Recent studies have demonstrated that warm coronal emissions during the extreme ultraviolet late phase (ELP) of X‐class solar flares can be sufficiently strong to also affect electron density in the Earth's ionosphere. The Fe XV 28.4 nm line was identified as one of the most geoeffective emissions produced during the ELP.
