1. 1. The fate of stars born in gas-rich high redshift galaxies

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Floor van Donkelaar; [2021]
   Keywords : Physics and Astronomy;

   Abstract : One of the greatest challenges astronomers are facing today is understanding how galaxies form. We know that the Milky Way is a spiral disk galaxy, similar to many others we see in the sky, therefore the Milky Way is a benchmark for understanding the inner workings of disk galaxies. READ MORE

3. 2. Analysis of stellar spectra with machine learning

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Alvaro Segovia Otero; [2020]
   Keywords : Galactic Archaeology; machine learning; chemical abundances; FGK stars; Physics and Astronomy;

   Abstract : Researchers in the field of Galactic Archaeology have entered the era of industrial revolution. Upcoming surveys are planning on observing tens of millions of stars and high precision and accuracy must be ensured when deriving their stellar parameters and elemental abundances. READ MORE

4. 3. Principal Component Analyses of Final States in Relativistic Nuclear Collisions using PYTHIA/Angantyr

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Nicoline Krogh Hemme; [2020]
   Keywords : Relativistic Nuclear Collisions; Heavy-ion Collisions; Pythia; Angantyr; String Shoving; Colour Reconnection; Principal Component Analysis; Anisotropic Flow; Elliptic Flow; Event-by-event Fluctuations; Physics and Astronomy;

   Abstract : We develop a program to perform a principal component analysis of flow fluctuations using simulations of nuclear collisions produced by the PYTHIA/Angantyr event generator. We consider both p+p and p+Pb collision events and study the leading and subleading modes of the second flow harmonic. READ MORE

5. 4. Coupling of a home-made simulated automatic mercury analyzer (AMA254) to a mercury fluorescence detector for total mercury determination in biological samples : -The use of a hydride generator system and atomic absorption spectroscopy to detect mercury in water samples

   University essay from Kemiska institutionen

   Author : Liem Nguyen Van; Henrik Tollin; Tu Tran Thanh; [2011]
   Keywords : ;

   Abstract : In this project we have been working with two different instruments home-made AMA 254 and Hydride Generator. Home-made AMA 254 was coupled to a fluorescence detector. The Hydride Generator was coupled to atomic absorption spectroscopy (AAS), by an optical path. READ MORE
