1. 1. Cosmic Dust Detection by the Solar Orbiter Using Machine Learning

   University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Joar Lönngren; Ludwig Tiston; [2023]
   Keywords : Machine Learning; Neural Network; Cosmic Dust; Solar Orbiter; Space Physics; Space Dust;

   Abstract : This project aims to investigate neural network systems as an effective tool for the in-space captured dust impact signal detection. Cosmic dust is the nanometre to micrometre fine-sized particles that exist in the interplanetary region. They originate from comets, asteroids, the planets and their moons and rings, or even the interstellar region. READ MORE

3. 2. The Effect of Gravitational Encounters on Binary Planetesimals

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : John Gillan; [2021]
   Keywords : Physics and Astronomy;

   Abstract : Binary planetesimals in the Kuiper belt can experience close encounters with other bodies. These encounters can disturb the orbital dynamics of the binary in several ways. Energy can be added to the system by the impactor body and lead to the disruption of the binary. READ MORE

4. 3. Foundation for an analysis of the dust of theNearby Universe

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Jimmy Kjellqvist; [2021]
   Keywords : Intergalacitc dust; dust distribution; cosmology; cosmological measurements; quasars;

   Abstract : The current cosmological paradigm of an accelerating cosmic expansion issupported by observations of Type Ia supernovae. However, the light emittedby these and other cosmological sources is not only redshifted by cosmicexpansion but will also interact with matter along the light path. READ MORE

5. 4. Study of CO Emission in Nine Hot Dust-Obscured Galaxies at z ∼3

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Timothy Faerber; [2021]
   Keywords : Galaxies; high-z; AGN; starburst; quasar; evolution; cosmology;

   Abstract : Massive galaxies evolve through different phases including starburst-dominated and active galactic nuclei (AGN)-dominated phases. These phases are predicted to be prevalent at earlier times (z ∼ 2 − 3). READ MORE

6. 5. Making Hypervelocity Stars

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Frans Forsberg; [2020]
   Keywords : Stellar Dynamics; Binary Stars; Galactic Centre; Binary Relaxation; Physics and Astronomy;

   Abstract : In this thesis, I investigate if the binaries that are being tidally disrupted by means of the Hills mechanism, producing hypervelocity stars, could have been transported to the galactic centre by two-body scattering. To survive a scattering event, the binary must be hard, meaning that the binding energy of the binary is higher than the kinetic energy of the collider. READ MORE
