1. Oscillations in a complex sunspot: From theory to data
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

4. Finding the Seeds of Supermassive Black Holes: The Direct Collapse Black Hole Scenario
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : The origin of supermassive black holes (SMBHs,∼ 10^9M⊙) in the first billion years of cosmic history remains a mystery. Direct Collapse Black Holes (DCBHs,∼ 10^4M⊙) are considered one of the most promising hypotheses for the progenitor of SMBHs, as they are believed to provide a favorable starting point as massive seeds for SMBH formation.

5. PERCEIVED BRIGHTNESS OF COLORED LIGHT : A study about the perceived brightness of near-monochromatic light in comparison to neutral white light
University essay from Jönköping University/JTH, Byggnadsteknik och belysningsvetenskapAbstract : Recently, there has been a notable rise in the use of colored lighting for both indoor andoutdoor spaces. This trend necessitates a clear understanding of the principles behindselecting lighting levels that are both ergonomic and energy efficient. The objective ofthis study was to establish guidelines for planning colored light. READ MORE
