  1. 16. Measuring the [C II]-to-H I connection in high-redshift absorption-selected galaxies

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Gaurav Senthil Kumar; [2022]
    Keywords : QSO; Quasar; Black Hole; AGN; Active Galactic Nuclei; DLA; Damped Lyman Alpha; C II; [C II]; H I; Sightline; HST; X-shooter; Spectroscopy; Echelle Spectroscope; Hyperfine transition; Hyperfine; Physics and Astronomy;

    Abstract : HI neutral gas is the basic building block of galaxies. It dictates the star formation rate and hence the metal enrichment rates within high redshift galaxies. HI neutral gas cannot be directly observed beyond z ≈ 0. READ MORE

  4. 18. 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

  5. 19. 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.

  6. 20. Investigating the central engine in supernova 2002ap using X-ray observations

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Amanda Helmfrid; Richárd Bagi; [2021]
    Keywords : ;

    Abstract : Supernovae (SNe) are explosions following the death of massive stars. Core-collapse supernovae (CCSNe) occur when the heavy iron core of these stars collapse in on themselves. The resulting remnant of the core of a CCSN is a compact object: either a black hole or a neutron star. READ MORE
