1. 16. Intermediate-mass black hole binary as an origin of super-massive black holes

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

   Author : Isabelle Signe Maj Maria Thord; [2023]
   Keywords : Intermediate-mass black holes; binary; merger; hardening; encounters; Physics and Astronomy;

   Abstract : Galactic nuclei contain super-massive black holes (SMBHs), nuclear stellar clusters (NSCs), or both. In the NSC, intermediate-mass black holes (IMBHs) are likely to reside and form highly eccentric binaries. Over time, the orbit of a binary could harden via interaction with surrounding low-mass stars. READ MORE

3. 17. Minimal Cantor sets

   University essay from KTH/Matematik (Avd.)

   Author : Jacob Nordin Gröning; [2023]
   Keywords : Cantor sets; Minimal Cantor sets; Inverse limits; Combinatorial Covers; Cantor mängder; Minimala Cantor mängder; Inversa gränser; Kombinatoriska övertäckningar;

   Abstract : A Cantor set is a topological space which admits a hierarchy of clopen covers. A minimal Cantor set is a Cantor set together with a map such that every orbit is dense in the Cantor set. In this thesis we us inverse limits to study minimal Cantor sets and their properties. READ MORE

4. 18. Classical Limits in Planetary Motion and Gravitational Radiation

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Sebastian Gustasson; Emma Andersson; [2023]
   Keywords : general relativity; frame-dragging; gravitational radiation;

   Abstract : In this report, we analyze general relativistic effects on celestial bodies, including gravitational strength in different metrics, gravitational radiation, and frame-dragging. We present simulation methods for classical and general relativistic motion, through the use of systems of equations that may be numerically integrated. READ MORE

5. 19. Academic cubesat development methodologies. : The cases of CREME and APTAS

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Carlos Sarille Cadenas; [2023]
   Keywords : Cubesat; Project Management; Systems Engineering; APTAS; CREME;

   Abstract : Since 2003, when the first batch of academic Cubesats was launched, 463 of these satellites havereached orbit. The issues faced in the early years were documented and since then the marketof Commercial off-the-shelf components, launch brokers and other auxiliary companies hassky-rocketed. READ MORE

6. 20. Testing of AblativeMaterials as a Protective Coating for Rocket Launch Pads

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Gioele Daka; [2023]
   Keywords : Ablative Materials; Protective Coating; Rocket Launchpad; Refractory Materials; Oxyacetylene Torch; Slug Calorimeter; Ablativa material; Skyddande beläggning; Raketstartplatta; eldfast material; acetylensyrebrännare; kopparkalorimeter;

   Abstract : As the space market grows, demand for sites to host rocket tests and to launch satellites to orbit is expected to increase. During these activities, the launch infrastructure needs to withstand the extreme thermal and mechanical loads associated with the exhaust of a rocket engine. READ MORE
