1. 1. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy

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

   Author : Erik Fridén; [2023]
   Keywords : Physics and Astronomy;

   Abstract : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. READ MORE

3. 2. Nowcasting the IRF Auroral Index with Recurrent Neural Networks

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Per Danielsson; [2022]
   Keywords : Aurora borealis; aurora; neural networks; artificial intelligence; machine learning; recurrent;

   Abstract : There is a long history in Kiruna of conducting research on the physics of the aurora borealis. There is also a long history of providing tourists with great opportunities to see the auroras. Planning such tourist activities can be challenging since the auroras are hard to predict. READ MORE

4. 3. Brightest Cluster Galaxies in the Local Universe: Mergers, Interactions and the Implications for Galaxy Evolution

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Diane Delley; [2022]
   Keywords : Brightest Cluster Gallaxies; BCG; Cosmology; Clusters of Galaxies; Merger; Interaction;

   Abstract : Clusters of Galaxies are amongst the largest gravitationally bound structures in our Universe and consist of thousands of galaxies. It is in these gigantic systems where Brightest Cluster Galaxies (BCGs) are found, the most massive galaxies in our Universe. A BCG, as its name indicates, is the brightest galaxy in a cluster.

5. 4. Identifying Gravitationally Lensed QSO Candidates with eROSITA

   University essay from Uppsala universitet/Observationell astrofysik

   Author : Róisín O'Rourke Brogan; [2020]
   Keywords : active galactic nuclei; agn; erosita; gaia; gravitational lensing; quasi-stellar objects; strong lensing; multiple images;

   Abstract : As of June 2020, the first all-sky X-ray survey with the eROSITA instrument aboard the spacecraft Spektr-RG has been completed. A high percentage of the 1.1 million objects included in the survey are expected to be active galactic nuclei (AGN). READ MORE

6. 5. Space Situational Awareness with the Swedish Allsky Meteor Network

   University essay from Uppsala universitet/Observationell astrofysik

   Author : Simon Alinder; [2019]
   Keywords : SSA; space situational awareness; IOD; initial orbit determination; orbit determination; satellite identification; all-sky; rymdlägessituation; SSA; omloppsbana; banbestämning;

   Abstract : This thesis investigates the use of the Swedish Allsky Meteor Network (SAMN) for observing, identifying, and determining the orbits of satellites. The overall goal of this project is to determine the feasibility of using such a network for Space Situational Awareness (SSA) purposes, which requires identification and monitoring of objects in orbit.
