1. 1. The quest for a classical bulge - a study of kinematics, abundances, and ages using microlensed dwarf stars and Gaia

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Calum Kvernes Macpherson; [2023]
   Keywords : Bulge; Milky Way; Kinematics; Galpy; Dwarf Stars; Physics and Astronomy;

   Abstract : Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter.

3. 2. Murphy's Law for Schemes

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Isak Sundelius; [2023]
   Keywords : algebraic geometry; matroids; Mnëv s theorem; Grassmannians;

   Abstract : This paper aims at presenting the necessary tools to prove that a scheme of finite type over Z exhibits the same singularities as those which occur on a Grassmann variety. First, basic theory regarding the combinatorial objects matroids is presented. READ MORE

4. 3. Characterization of the role of RbfA and KsgA in ribosome function

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Carina Kvernes Macpherson; [2022]
   Keywords : ;

   Abstract : Ribosome biogenesis is the maturation and accurate assembly of ribosomal RNA and proteins to form functional ribosomes competent to enter the translation cycle, facilitated by the action of ribosome biogenesis factors. RbfA and KsgA are two factors involved in late stages of the 30S subunit biogenesis, yet before translation initiation. READ MORE

5. 4. Carbon Abundance in the Milky Way Galaxy

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Calum Kvernes Macpherson; [2021]
   Keywords : Carbon; Abundance; Milky Way; Chemical Evolution; Physics and Astronomy;

   Abstract : Carbon is the fourth most abundant element after hydrogen, helium and oxygen. It is a product of stellar nucleosynthesis as well as it being an important bio signature for life; this makes the analysis of carbon very fundamental. READ MORE

6. 5. Studying genetics of leaf shape variation in Arabidopsis lyrata

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Carina Kvernes Macpherson; [2019]
   Keywords : Arabidopsis lyrata; Arabidopsis arenosa; leaf shape; RCO genes; genotype; phenotype; gene sequence variation;

   Abstract : The relationship between leaf and its environment has resulted in a tremendous diversification of leaf shape within and between plants species, which is important to cope with the differing environmental conditions. Arabidopsis lyrata is a prime model plant that shows leaf shape variation within species and between related species. READ MORE
