  1. 11. Spectroscopic analysis of exoplanet atmospheres : Ground-based high-resolution atmospheric characterization of hot Jupiters using near infrared spectroscopy

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Emelie Stoltz Årevik; [2015]
    Keywords : ground-based high-resolution atmospheric atmosphere characterization hot Jupiters near infrared spectroscopy;

    Abstract : This report is exploring the possibility of characterizing hot Jupiter atmospheres using ground-based high-resolution spectroscopy. The ESO CRIRES infrared spectrometer is selected as the observing tool. Simulated observations are computed for known transiting systems. READ MORE

  2. 12. X-ray observations of the radio-loud narrow-line Seyfert 1 J1548+3511.

    University essay from KTH/Fysik

    Author : Theodor Isacsson; Jenny Stoby Höglund; [2014]
    Keywords : ;

    Abstract : A major open question in astrophysics concerns the formation of highly collimated beams of matter and electromagnetic radiation, so-called relativistic jets, emerging from active galactic nuclei (AGN) in the center of certain galaxies. It is not known how, or why, these jets are formed nor how they maintain their collimated state for such large distances. READ MORE

  3. 13. Evaluation of weighting functions for Sidelobe control in UWB SAR image processing

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Habiba Akhter; [2013]
    Keywords : Image processing; Synthetic aperture radar SAR ; Ultra Wideband UWB ; Apodization; Impulse Response IPR Function;

    Abstract : Ultra wideband (UWB) Synthetic Aperture Radar (SAR) holds huge possibilities for both terrestrial and celestial object sensing with excellent details which assists in science and technology. SAR systems associated with large antenna beamwidth, large signal bandwidth and low frequency operating in the VHF/UHF region is becoming gradually more popular because of their rising number of application in the areas of ground-penetrating radar (GPR) and foliage penetration radar (FOPEN).
