Trends and Characteristics of High-Frequency Type II Bursts Detected by CALLISTO Spectrometers

A. C. Umuhire, J. Uwamahoro, K. Sasikumar Raja +22

Solar radio type II bursts serve as early indicators of incoming geo-effective space weather events such as coronal mass ejections (CMEs). In order to investigate the origin of hig…

The rise and fall of the UV upturn: $z = 0.3, 0.55$ and $0.7$

Sadman Ali, Malcolm Bremer, Steven Phillipps +7

We have analysed the strength of the UV upturn in red sequence galaxies with luminosities reaching to below the $L^{*}$ point within four clusters at $z$ = 0.3, 0.55 \& 0.7. We find…
