  1. 6. Search for transiting exoplanets in globular clusters

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

    Author : Oskar Nilsson; [2023]
    Keywords : Physics and Astronomy;

    Abstract : This project consists of a transit search in the Messier 3 Globular cluster with the goal to assess the difficulties of observing planetary transits in globular clusters. M3 was observed for a short period of time and by performing PSF fitting, flux measurements could be done to extract light curves of the 290 stars that are included in this project. READ MORE

  3. 7. Searching for direct collapse black holes using the James Webb Space Telescope

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Edison Arellano Almeida; [2022]
    Keywords : extragalactic astronomy;

    Abstract : Recent detections of massive quasars at z > 6 has proven to be an interesting challengefor cosmology given the short time frame that these objects have to reach a certainmass via conventional methods (e.g., galaxy mergers). READ MORE

  4. 8. Black Holes of the First Stars

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Aron Kordt; [2022]
    Keywords : ;

    Abstract : In this report, we constrain properties of foreground objects in the Milky Way that have the potential of being confused with accretion disks of Population III stellar- mass black holes at high redshift. Following Windhorst et al. (2018), a model for multicolour accretion disks of Population III stellar-mass black holes is presented. READ MORE

  5. 9. Making the Invisible Visible: A Study of Exoplanet Visualisation

    University essay from Lunds universitet/Avdelningen för konsthistoria och visuella studier

    Author : Ankita Sharma; [2022]
    Keywords : exoplanet; visualisations; scientific representations; TRAPPIST-1; objectivity; Physics and Astronomy;

    Abstract : Exoplanets are planets found around other stars in the Universe. Although astronomical studies have found and confirmed the existence of exoplanets, they are too far away to be photographed directly, so there are dedicated visualisation scientists who use the data collected on them to create hypothetical visualisation.

  6. 10. Detecting Transiting Exoplanets in Crowded Fields

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Eddie Larsson; [2022]
    Keywords : Transit method; Globular cluster; crowded environments; exoplanets; transiting exoplanets; Physics and Astronomy;

    Abstract : The first planet orbiting a main-sequence star was discovered in 1995. Since then more than 4000 additional exoplanets have been discovered. This is a rapidly evolving field in astrophysics. One of the most common ways to detect an exoplanet is through transit, as the brightness of the host star decreases. READ MORE
