  1. 1. Finding new members of the VelHel-4 stream

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Lucas Johansson; [2023]
    Keywords : Galactic Archaeology; Milky Way; Stellar Streams; Streams; Stellar Halo; Stars; Globular Cluster; Astronomy; Astrophysics; Gaia; Chemical Abundance; Spectroscopy;

    Abstract : According to the paradigm of lambda-CDM cosmology, the stellar halo ofour Galaxy has been built-up over time through the accretion of other galaxiesand star clusters. The remnants of some of these are still observable today asstellar streams, but are typically very faint and difficult to resolve amidst the farmore numerous foreground Milky Way stars. READ MORE

  3. 2. Thawing, Scaling and Tracking QUintessence in a Phase Space Perspective : and comparisons to the ΛCDM model

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Arvid Ryberg; [2022]
    Keywords : Quintessence; Cosmology; Dark Energy; Astro physics;

    Abstract : This thesis aims to give an introduction to quintessence models as well ascomparing those models with the currently accepted ΛCDM model. We willconsider quintessence in a spatially flat and isotropic Universe and useregular dynamical systems on a bounded three dimensional phase spacewhere we perform numerical calculations. READ MORE

  4. 3. Development of Operations Complement to the Space System Ontology

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Kiira Tiensuu; [2022]
    Keywords : space systems engineering; model-based systems engineering;

    Abstract : Space system development is a complex process that typically involves multiple stakeholders. Traditionally, information is captured and exchanged in the form of documents. Efficient exchange of information is crucial, but often challenging with the traditional document-based approach and multitude of stakeholders. READ MORE

  5. 4. A Tension between the Early and Late Universe: Could Our Underdense Cosmic Neighbourhood Provide an Explanation?

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Sveva Castello; [2021]
    Keywords : Cosmology; Hubble tension; local void;

    Abstract : In recent years, the increasingly precise constraints on the value of the Hubble constant, H0, have highlighted a discrepancy between the results arising from early-time and late-time measurements. A potential solution to this so-called Hubble tension is the hypothesis that we reside in a cosmic void, i.e. READ MORE

  6. 5. Integrating Virtual Operations Support Teams (VOSTs) into domestic crisis and disaster management structures – An exploratory study of challenges and requirements for improvement

    University essay from Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Melina Semke; [2021]
    Keywords : Social media; digital volunteers; trusted agents; certified volunteers; Germany; digitalisation; innovation in crisis and disaster management; Social Sciences;

    Abstract : Social media (SM) use in crisis and disaster management (CDM) is resource-intensive and can overwhelm emergency management authorities (EMAs). Digital voluntarism offers SM capacities for EMAs. A significant approach to reap benefits from digital voluntarism for domestic CDM is introducing Virtual Operations Support Teams (VOSTs). READ MORE
