11. On Fermi-like neutrino acceleration in core-collapsesupernovae and around black hole formation, andthe evolution of observable neutrino flux duringproto-neutron star collapse
Master-uppsats, Stockholms universitet/Institutionen för astronomiSammanfattning : 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. LÄS MER
12. Understanding Rt using two-particle correlations by simulating proton-proton collisions in a Monte-Carlo model
Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : The observable Rt is investigated in the Monte Carlo Model Pythia in order to better understand results from experimental data obtained in the ALICE detector at CERN. The purpose is to reproduce the experiment in a simulation and use the features proposed by Pythia to dig into the unexpected outcomes. LÄS MER
13. Investigating the central engine in supernova 2002ap using X-ray observations
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : 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. LÄS MER
14. The visibility of double neutron star binaries to LISA
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : 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. LÄS MER
15. The retention of black holes in globular clusters
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationSammanfattning : 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. LÄS MER
