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 astronomiAbstract : 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

2. The definition of fens and bogs : An international meta-study
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : 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

3. Forming wide-orbit planets via pebble accretion
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : 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

4. Testing the detectability of supernova ejecta from Population III stars with future ELT/ANDES
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : 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. 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 StudiesAbstract : 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
