Deciphering Type III Solar Radio Bursts Associated with X-class Flares during the 2024 Mother’s Day Storm

The Astrophysical Journal
Type III solar radio bursts trace electron acceleration and escape during solar flares and jets, offering key diagnostics of solar eruptive processes. Using high-resolution Parker Solar Probe (PSP) data, we analyzed 11 type III bursts associated with X ...

A Poor’s Man Approach to Solar Radio Emission Characterization [PDF]

Proceedings of the 4th URSI Atlantic RadioScience Conference – AT-RASC 2024
The Sun (both the photosphere and the corona) is a strong source of radiation across the entire RF spectrum. Under some particular circumstances, Sun noise may heavily interfere with ground receivers for communication satellites or deep space probes, causing degradation, or even destruction, of the useful signal.

Evidence for solar wind control of Saturn radio emission [PDF]

, 1982
Using data collected by the Voyager 1 and 2 spacecraft in 1980 and 1981, strong evidence is presented for a direct correlation between variations in the solar wind at Saturn and the level of activity of Saturn's nonthermal radio emission.

Sub‐Nanometer Cobalt on Tungsten Titanium Carbide MXene (W2TiC2Tx): An Electrocatalyst for Highly Efficient and Stable Alkaline Hydrogen Evolution at Industrial‐Scale Current Density

Advanced Materials, EarlyView.
A novel W2TiC2Tx MXene prepared through a MAX‐phase route supports sub‐nanometer Co for highly efficient alkaline hydrogen evolution. Strong Co–W interfacial interactions optimize hydrogen adsorption and catalytic activity, enabling low overpotentials of 63 mV at 10 mA cm−2, small Tafel slope of 44.3 mV dec−1, and exceptional durability at industrially

RETRACTED: Quantitative prediction of type II solar radio emission from the Sun to 1 AU

Geophysical Research Letters, 2016
Coronal mass ejections (CMEs) are frequently associated with shocks and type II solar radio bursts. Despite involving fundamental plasma physics and being the archetype for collective radio emission from shocks, type II bursts have resisted detailed ...

Small-scale Inhomogeneity Effects on Coherent Solar Radio Emission

The Astrophysical Journal
The coherent radio emission mechanism of solar radio bursts (SRBs) is one of the most complicated and controversial topics in solar physics. To clarify the mechanism(s) of different types of SRBs, (radio-) wave excitation by energetic electrons in ...
