Electron acceleration efficiency during the impulsive phase of a solar flare: X-ray and microwave observations
Solar flares are known to be prolific electron accelerators, yet identifying the mechanism(s) for such efficient electron acceleration in magnetic reconnection events at the sun (and similar astrophysical settings) presents a major challenge in astro.....»»
New computational insights use Marcus theory to unlock the potential of photocatalysis
Dr. Albert Solé-Daura and Prof. Feliu Maseras have explored the application of the Marcus theory, traditionally used to model electron transfer, to estimate the free-energy barriers underlying energy transfer (EnT) processes. These results support t.....»»
Observations provide crucial insights into the nature of a white dwarf–brown dwarf binary
Using the Hubble Space Telescope (HST), astronomers have performed spectrophotometric observations of an eclipsing white dwarf–brown dwarf binary known as WD1032+011. Results of their observational campaign, published September 10 on the preprint s.....»»
Arctic warming may fuel ice formation in clouds, observations suggest
The Arctic frequently experiences temperatures that support the formation of mixed-phase clouds that contain supercooled liquid droplets and ice crystals. The composition of such clouds plays a crucial role in the region's energy balance and climate.....»»
