1. 1. Simulation-based discrimination of Crab pulsar models with XL-Calibur

   Master-uppsats, KTH/Fysik

   Författare :Dennis Åkerström; [2024]
   Nyckelord :Astroparticle Physics; Astrophysics; Detector Physics; Simulation; Theoretical Physics; Engineering Physics; Pulsar models; Crab pulsar; Astropartikelfysik; Astropartikelfysik; Detektorfysik; Simulering; Teoretisk Fysik; Teknisk Fysik; Pulsar modeller; Krabbpulsaren;

   Sammanfattning : Polarisation of X-ray light is being investigated with polarimeters to extend the borders of what can be observed. Distant compact objects, such as pulsars, that are to small on the sky to be analysed with imaging can be investigated by analysing the polarisation of the emitted light. This can reveal physics previously hidden by their small nature. LÄS MER

3. 2. Deriving Spectral Maps from JWST Data : A Study of Enceladus’ Plumes

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Stephan Weissenböck; [2023]
   Nyckelord :Data Analysis; Enceladus; Plumes; Atmosphere; JWST; NIRSpec; IFU; Infrared spectroscopy; Dataanalys; Enceladus; plym; atmosfär; JWST; NIRSpec; IFU; infraröd spektroskopi;

   Sammanfattning : This study investigates the presence of water vapor plumes in the region south of Enceladus, a moon in the Saturnian system, through observations conducted by the James Webb Space Telescope. Enceladus is believed to harbor a subsurface ocean or localized water reservoir that gives rise to water geysers, expelling vapor into its tenuous atmosphere and outer space. LÄS MER

4. 3. Non-Diffractive Nuclear Excitations In Angantyr

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Carl Rosenkvist; [2023]
   Nyckelord :Heavy-ion; non-diffractive; nuclear excitation; secondary interactions; Physics and Astronomy;

   Sammanfattning : To better understand collectivity in high energy physics, the heavy-ion collision model Angantyr was developed to be included in the event generator Pythia. In this model, proton-proton collision phenomenology is extrapolated to heavy-ion collisions without assuming a thermal plasma for particle production. LÄS MER

5. 4. Development of a Level-0 Geoprocessing Platform for a Multispectral Remote Sensing Payload

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Sergio Santiago Bernabeu Peñalba; [2022]
   Nyckelord :Infrared imagery; VIS; NIR; LWIR; geoprocessor; geolocation; quaternions; Aistech Space; image processing; ORB; RANSAC; Sentinel; Landsat; Infraröda bilder; VIS; NIR; LWIR; geoprocessor; geolokalisering; kvarternioner; Aistech Space; bildbehandling; ORB; RANSAC; Sentinel; Landsat;

   Sammanfattning : This thesis presented an overview of the development of a geolocating algorithm as part of a geoprocessor for raw satellite imagery. This algorithm was devised for and limited by the specifications of a state-of-the-art multispectral telescope designed by Aistech Space, hosted onboard the Guardian spacecraft, which will observe Earth through the visible, near infrared, and thermal infrared bands of the electromagnetic spectrum.

7. 5. Feasibility study of initial orbit determination with open astronomical data

   Master-uppsats, KTH/Fysik

   Författare :Linn Mattsson; [2022]
   Nyckelord :Space situational awareness; Space surveillance and tracking; Image analyse; Streak detection algorithm; Initial orbit determination; Rymdlägesbild; Bildanalys; Algoritm för streck detektering; Initial banbestämning;

   Sammanfattning : In this report I present a feasibility study of using open astronomical data to make Initial Orbit Determination (IOD) for Resident Space Objects (RSO) appearing as streaks in telescope images. The purpose is to contribute to Space Surveillance and Tracking (SST) for maintaining Space Situation Awareness (SSA). LÄS MER
