  1. 21. High-Redshift Gamma-ray Bursts as seen by SVOM/ECLAIRs

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Miguel Llamas Lanza; [2021]
    Keywords : Gamma-ray Bursts; GRBs; compact objects; high energy; ECLAIRs; SVOM; high redshift; T90; detection biases;

    Abstract : Gamma Ray Burst (GRB) are very bright cosmological explosions signalling the catastrophic formation of a black hole. Therefore, they act like real light beacons that could be detected through-out the Universe and be used as probes to study the contents and phases of the early Universe. However, only a handful sample is known so far. READ MORE

  3. 22. Recent Progress on the Black Hole Information Paradox

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Eivind Hilmen Jørstad; [2021]
    Keywords : Black Holes; Hawking Radiation; Entanglement Entropy; Black Hole Information Paradox; Dilaton Gravity; Quasiparticles; Physics and Astronomy;

    Abstract : The black hole information paradox is of central importance in the study of quantum gravity. The paradox states that quantum fields surrounding a black hole behave in ways that run into conflict with the unitarity of quantum mechanical time evolution. READ MORE

  4. 23. The retention of black holes in globular clusters

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Wuxueman Liu; [2021]
    Keywords : Physics and Astronomy;

    Abstract : We simulate the velocities of formed Black Holes to determine the fraction of retained Black Holes in 152 Globular Clusters. The model we used for the escape velocity is from Plummer. The scenarios of the natal kick are Neutronstar like kicks and momentum conserving kicks. READ MORE

  5. 24. Seeing Stars - Intensity Interferometry in the Laboratory and on the Ground

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Colin Carlile; [2021]
    Keywords : Stellar Physics Instrumentation Interferometry Cherenkov Telescope Array Intensity Interferometry; Physics and Astronomy;

    Abstract : Context Since the time of Tycho Brahe astronomy has been an observing science defined by the quality of its instrumentation. The introduction of primitive telescopes by Galileo in 1609 began a period of development of ever-larger telescopes with greater measuring precision. READ MORE

  6. 25. Black holes as standard candles through their Hawking radiations.

    University essay from Stockholms universitet/Fysikum

    Author : Tabatha DUFOUR; [2021]
    Keywords : ;

    Abstract : As they are evaporating, black holes are emitting radiations called Hawking radiations. Our goal is to determine at which distance it is possible to measure those radiations with current telescopes. Being capable of measuring those radiations would mean that we can use them as standard candles i.e. READ MORE
