1. 16. Investigating the central engine in supernova 2002ap using X-ray observations

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Amanda Helmfrid; Richárd Bagi; [2021]
   Keywords : ;

   Abstract : Supernovae (SNe) are explosions following the death of massive stars. Core-collapse supernovae (CCSNe) occur when the heavy iron core of these stars collapse in on themselves. The resulting remnant of the core of a CCSN is a compact object: either a black hole or a neutron star. READ MORE

3. 17. Radio Emissions from Earth’s Foreshock and Bolides

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Patrick Oppel; [2021]
   Keywords : ;

   Abstract : It is well understood that Earth’s foreshock radiation is due to the bow shock deflecting the solar wind and accelerating electrons upstream into the foreshock where they produce Langmuir waves and radio emissions. Recently, the Long Wavelength Array (LWA) in the USA observed radio waves from meteors and other bolides entering the ionosphere and atmosphere. READ MORE

4. 18. Recent Progress on the Black Hole Information Paradox

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Eivind Hilmen Jørstad; [2021]
   Keywords : Black Holes; Hawking Radiation; Entanglement Entropy; Black Hole Information Paradox; Dilaton Gravity; Quasiparticles; Physics and Astronomy;

   Abstract : The black hole information paradox is of central importance in the study of quantum gravity. The paradox states that quantum fields surrounding a black hole behave in ways that run into conflict with the unitarity of quantum mechanical time evolution. READ MORE

5. 19. Design and Commissioning of Pulsed Wire Magnetic Measurement System for Insertion Device Characterization

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

   Author : Mohammed Ebbeni; [2021]
   Keywords : pulsed wire; synchrotron; radiation; insertion device; undulator; wiggler; magnetic measurement; hall-probe; hall probe; commissioning; phase error; euler bernoulli; beam; coupled vibration; optical sensor; laser sensor; vibrations; photodiode; beamline; Physics and Astronomy;

   Abstract : Synchrotron and Free Electron Laser (FEL) light is becoming an increasingly sought after tool for almost all scientific research aspects. MAX IV Laboratory introduced the first 4th generation light source that provides the brightest synchrotron light in the world. READ MORE

6. 20. Modelling And Simulation of Attitude AndOrbital Control For Foresail-2

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Tushar Sharma; [2021]
   Keywords : ;

   Abstract : A central factor affecting spacecraft lifetime is the radiation environment, which isunpredictable due to an incomplete understanding of plasma dynamics. FORESAIL2 will build on the FORESAIL-1 results – measurements of radiation belt lossesand demonstrate deorbiting in LEO. READ MORE
