6. Analys och vidareutveckling av simuleringsmiljö för LFC-reglering inom NBM-programmet
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : The control and balancing measures for achieving safe grid operation in the Nordic power grid is becoming increasingly complex with larger penetrations of renewable power, new guidelines aiming to increase digitalisation and automation alongside integration into European balancing platforms. The power grid operators are faced with new challenges for safely operating the grid leading to an increased need for theoretical and practical education. LÄS MER
7. Warm dark matter simulations and 21cm astronomy
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : The recent boom in 21cm astronomy has piqued the interest of many, especially cosmologists realizing its applications in their field. This study aims to determine if 21cm astronomy is a good tool for testing the validity of keV WDM models, as well as creating a code capable of simulating keV WDM models from an existing CDM code.

8. Svenska gymnasieelevers uppfattningar om storlek och avstånd i universum
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för utbildningsvetenskapSammanfattning : This study aims to investigate how students in Swedish upper secondary school conceptualize sizes and distances of some astronomical objects, such as planets and stars, as well as the students’ general knowledge of the objects themselves. The study uses a constructivist framework and explores how well the students’ conceptions match the scientific facts and definitions, and what misconceptions and alternative conceptions they hold.

9. Magnetic field of the magnetic chemically peculiar star V1148 Ori
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : This project aims to obtain and interpret the measurements of the mean longitudinal magnetic field of the chemically peculiar star V1148 Ori. To achieve this aim 12 spectropolarimetric observations obtained by the CFHT using the spectropolarimeter ESPaDOnS were used. LÄS MER
10. Resolving the smallest scale of star formation at Cosmic Noon with JWST : Star-forming clumps in a galaxy lensed by Abell 2744
Master-uppsats, Stockholms universitet/Institutionen för astronomiSammanfattning : At higher redshift galaxies exhibit increasingly irregular and clumpy morphologies, withstar-forming clumps dominating the FUV output of their host galaxies thus being inti-mately related to star formation and the formation and evolution of galaxies. This workexamines star-forming clumps in a remarkable, young spiral galaxy at Cosmic Noon witha redshift ofz= 2. LÄS MER
