1. X-ray variability in Galactic high-mass black hole binaries
Sammanfattning : The stars of the night sky can to the naked eye appear to be steady and unchanging, apart from the twinkling created by air moving in the atmosphere. However, when viewed in X-rays, the sky is far from constant, with detectable changes occurring on very short timescales.Black hole X-ray binaries are strong sources of X-rays. LÄS MER
2. Extending the observational reach of core-collapse supernovae for IceCube using high-energy neutrinos
Sammanfattning : Neutrino telescopes such as IceCube monitor for low-energy neutrinos O(10 MeV) produced in nuclear processes during core-collapse in supernovae. The detection horizon to the neutrino burst is 50 kpc, the distance to the Magellanic Clouds. LÄS MER
3. Parametric Model for Astrophysical Proton-Proton Interactions and Applications
Sammanfattning : Observations of gamma-rays have been made from celestial sources such as active galaxies, gamma-ray bursts and supernova remnants as well as the Galactic ridge. The study of gamma rays can provide information about production mechanisms and cosmic-ray acceleration. LÄS MER
4. Cosmic rays and shock physics in gamma-ray bursts
Sammanfattning : Gamma-ray bursts (GRBs) are the most luminous events in the known universe. Due to their tremendous energy output, they serve as laboratories of physics far beyond anything that we can hope to achieve in terrestrial experiments. LÄS MER
5. Multi-messenger emission from gamma-ray bursts
Sammanfattning : Multi-messenger astronomy is a very hot topic in the astrophysical community. A messenger is something that carries information. Different astrophysical messenger types are photons, cosmic rays, neutrinos, and gravitational waves. They all carry unique and complementary information to one another. LÄS MER
