  1. 1. Upscaling agroecology in Sweden : a participatory-backcasting approach to investigate top-down measures for promoting an agroecological transition of the Swedish agricultural system

    University essay from SLU/Dept. of People and Society

    Author : Pablo Ratti; [2023]
    Keywords : Agroecology; transition; top-down; scenario; participatory policies;

    Abstract : Alongside its important contribution to the increase of yields, industrial agriculture has also generated environmental, social and economical negative side effects. Moreover, the forecasted growth of the world’s population puts more pressure for solutions on how to increase food supply while reducing the negative effects of the current agricultural system.

    Abstract : “I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.” ― Albert Einstein Today we live in very interesting times for researchers but at the same time very dangerous for the whole human existence and our planet. READ MORE

  4. 3. Testing the detectability of supernova ejecta from Population III stars with future ELT/ANDES

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Aron Kordt; [2023]
    Keywords : ;

    Abstract : The first stars, known as Population III (Pop III) stars, formed when the Universe was about 100 Myr to 200 Myr old. In contrast to the present-day Universe, star formation took place in a basically metal-free environment. Despite several decades of research, Pop III stars have not yet been directly observed.

  5. 4. Black Holes of the First Stars

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Aron Kordt; [2022]
    Keywords : ;

    Abstract : In this report, we constrain properties of foreground objects in the Milky Way that have the potential of being confused with accretion disks of Population III stellar- mass black holes at high redshift. Following Windhorst et al. (2018), a model for multicolour accretion disks of Population III stellar-mass black holes is presented. READ MORE

  6. 5. Starbursts at Cosmic Dawn : Formation of Globular Clusters, Ultra-Faint Dwarfs, and Population III star clusters at z > 6

    University essay from Stockholms universitet/Institutionen för astronomi

    Author : Olof Nebrin; [2022]
    Keywords : Cosmology; Galaxy Formation; Globular Clusters; First Stars; Dark Matter; Cosmic Dawn; Reionization; Ultra-Faint Dwarfs;

    Abstract : In the standard model of cosmology (ΛCDM) the first stars, star clusters, and galaxies are expected to have formed in short bursts of star formation in low-mass dark matter halos at high redshifts (). Up to this point, attempts to predict the properties and abundances of these luminous objects have made use of numerically expensive cosmological simulations. READ MORE
