  1. 21. Escaping Compact Object Binaries from Globular Clusters

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Annie Csomor; [2022]
    Keywords : Compact object binaries; binary black holes; BH-NS binaries; escaping binaries; globular clusters; escaping compact object binaries from globular clusters; escaping compact binaries; Physics and Astronomy;

    Abstract : Since 2015, the LIGO-Virgo-KAGRA scientific collaboration (LVK) has detected gravitational waves from more than 90 merging compact object binaries using ground-based interferometric detectors. Compact objects orbiting in binary systems emit gravitational waves leading to a loss of energy. READ MORE

  3. 22. On Fermi-like neutrino acceleration in core-collapsesupernovae and around black hole formation, andthe evolution of observable neutrino flux duringproto-neutron star collapse

    University essay from Stockholms universitet/Institutionen för astronomi

    Author : Samuel Gullin; [2021]
    Keywords : core collapse black hole neutrino acceleration supernova;

    Abstract : Failed supernovae are the implosive final fates of massive stars, where ablack hole is formed. During the collapse, the proto-neutron star emits a huge number of neutrinos, and when the black hole is finally formed, it engulfs theneutrino-emitting material and the signal is cut off. READ MORE

  4. 23. Markov Chain Monte Carlo (MCMC) and Bayesian Inference for Gravitational Waves

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Christine Andersson; [2021]
    Keywords : Gravitational Waves; LISA; LISA mission; Bayesian Inference; Markov Chain Monte Carlo; MCMC; Bayes’ Theorem; stochastic sampling; Metropolis Hastings; histograms; Physics and Astronomy;

    Abstract : The Laser Interferometer Space Antenna (LISA) is a space borne gravitational wave detec- tor set to launch in 2034, with the objective of detecting and studying the Gravitational Waves (GWs) of our universe. So far, ground-based detectors such as the Laser Interferometer Gravitational-Wave Observatory (LIGO) have been successful in detecting GWs, but the limitations of ground based detectors is what makes LISA so special.

  5. 24. Constraints on the High-Energy Gamma-Ray Spectrum of Nearby Star-Forming Galaxies

    University essay from Stockholms universitet/Fysikum

    Author : Oskar Svenborn; [2021]
    Keywords : Gamma-ray emission; High-Energy astrophysics; Star-Forming Galaxies; Star formation; Cosmic rays; Fermi-LAT.;

    Abstract : The nature of high-energy gamma-ray emission from Star-Forming Galaxies is of utmost importance for understanding both the origin of Cosmic Rays and the high-energy processes that shape galaxy formation. Observations from the gamma-ray telescope Fermi-LAT have detected gamma-ray emission from a handful of nearby Star-Forming Galaxies. READ MORE

  6. 25. The visibility of double neutron star binaries to LISA

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Anatole Storck; [2021]
    Keywords : gravitational waves; LISA; neutron stars; orbital simulations; Runge-Kutta method; Physics and Astronomy;

    Abstract : Double neutron star binaries (DNSBs) in the mHz gravitational wave (GW) regime are an important group of objects which the GW detector LISA will be able to observe. The detection and parametrization of these objects will help develop our current understanding of neutron star formation and evolution. READ MORE
