1. 1. Resolving the smallest scale of star formation at Cosmic Noon with JWST : Star-forming clumps in a galaxy lensed by Abell 2744

   University essay from Stockholms universitet/Institutionen för astronomi

   Author : Annalena Pless; [2023]
   Keywords : star formation; star-forming clumps; galaxy evolution;

   Abstract : At higher redshift galaxies exhibit increasingly irregular and clumpy morphologies, withstar-forming clumps dominating the FUV output of their host galaxies thus being inti-mately related to star formation and the formation and evolution of galaxies. This workexamines star-forming clumps in a remarkable, young spiral galaxy at Cosmic Noon witha redshift ofz= 2. READ MORE

3. 2. The definition of fens and bogs : An international meta-study

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Zakaria Hachicho; [2023]
   Keywords : fens; bogs; fen; bog; peatland; peatlands; mire; mires; classification; definition; kärr; mosse; torvmark; myr; klassificering; definition;

   Abstract : Disagreements on how fens and bogs are defined warrants an evaluation of how researchers classify these habitats. Ongoing work with a new typology for ecosystems creates an urgency to understand the classification in the field. READ MORE

4. 3. Forming wide-orbit planets via pebble accretion

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

   Author : Nerea Gurrutxaga; [2023]
   Keywords : Planet Formation; Pebble Accretion; Protoplanetary Disk; Wide-Orbit Planet; Physics and Astronomy;

   Abstract : The possibility that detected substructures in protoplanetary disks, such as gaps, rings and cavities, are created by distant protoplanets has prompted an inquiry into the mechanism responsible for their formation. These wide-orbit young bodies are likely to form relatively rapidly in the outer regions of circumstellar disks. READ MORE

5. 4. 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.

6. 5. Minskande senvuxenhet på produktiv skogsmark i Norrland : implikationer för vedlevande organismer och betydelsen av myr- och bergimpediment

   University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

   Author : Tyr Nilsson; [2022]
   Keywords : Slow-grown trees; growth rate; ring width; pinus sylvestris; picea abies; low-productive forests; mires; rocky outcrops; swedish NFI;

   Abstract : Senvuxen ved är ett viktigt substrat för vissa vedlevande organismer på grund av en långsam nedbrytning och låg konkurrens. Tillväxtförhöjande åtgärder inom skogsbruk, liksom ökande temperaturer, kan ha orsakat en minskning av senvuxen ved under den senare halvan av 1900-talet. READ MORE
