1. PERFORMANCE OF THE PHOTODETECTOR FOR THE ACTIVE SHIELD OF THE COSI SPACE TELESCOPE
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : The COmpton Spectrometer and Imager (COSI) is a space telescope that aims to study the soft gamma regime (0.2-5 MeV), capable of performing spectroscopy, imaging and polarimetry of cosmic gamma sources.

2. Simulating and Testing the Polarimetric Response of the X-ray Polarimetry Telescope XL-Calibur
University essay from KTH/FysikAbstract : X-ray polarimetry, the study of the polarisation of X-ray light, is a powerful and rapidly developing tool for astrophysics, which promises to help answer outstanding questions about the physics of extreme objects such as pulsars, X-ray binaries and active galactic nuclei. The balloon-borne telescope XL-Calibur will be the first instrument to study the polarisation of hard X-rays (with energies between 10 and 100 keV) in detail, correlating with the soft X-ray observations of IXPE to provide further tests of polarisation-dependent x-ray emission models in extreme objects.

3. Study of Environmental Effects on Photo-MultiplierTubes for the X-ray Polarimetry Mission XL-Calibur
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : XL-Calibur is a balloon-borne hard X-ray polarimetry mission with goals to analyze celestial objects too small and distant to be imaged. A crucial part of XL-Calibur is the anti-coincidence shield which through active collimation reduces unwanted hits when gathering data. READ MORE

4. Target Orientation Detection Using UWB SAR by Implementing Polarimetry Technique
University essay from Högskolan i Gävle/ElektronikAbstract : In a recently started research project which took place at University of Gavle during the year 2015 an ultra-wideband (UWB) synthetic aperture radar (SAR) for non-destructing evaluation of walls was used to detect the metal target (pipe). The SAR used is designed by a small radar company in Gavle called Radarbolaget. READ MORE

5. T Tauri stars : Optical lucky imaging polarimetry of HL and XZ Tau
University essay from Institutionen för astronomiAbstract : Optical lucky imaging polarimetry of HL Tau and XZ Tau in the Taurus-Auriga molecular cloud was carried out with the instrument PolCor at the Nordic Optical Telescope (NOT). The results show that in both the V- and R-band HL Tau show centrosymmetric structures of the polarization angle in its northeastern outflow lobe (degree of polarization ~30%). READ MORE
