1. Probing the Structure of Ionised ISM in Lyman-Continuum-Leaking Green Pea Galaxies with MUSE
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : Lyman continuum (LyC) photons are known to be responsible for reionising the universe after the end of the Dark Ages, which marked a period called the Epoch of Reionisation (EoR). While these high-energy photons are thought to predominantly originate from young, hot, massive stars within the earliest galaxies, and contributions from high-energy sources like quasars and AGN, the origins of these photons are yet not well known and highly debated.

2. Investigating the central engine in supernova 2002ap using X-ray observations
University essay from KTH/Skolan för teknikvetenskap (SCI)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

3. The Milky Way and its Exoplanets
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : The detections of over 4000 exoplanets as of today has shown that they exist in a wide range of different configurations, otherwise known as architectures. Recently, studies have been made trying to link the environment of host stars to the architectures of their planetary systems and have found that the architectures of planetary systems may not necessarily be uniform in the Milky Way.

4. Carbon Abundance in the Milky Way Galaxy
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : Carbon is the fourth most abundant element after hydrogen, helium and oxygen. It is a product of stellar nucleosynthesis as well as it being an important bio signature for life; this makes the analysis of carbon very fundamental. READ MORE

5. Pulsation Properties in Asymptotic Giant Branch Stars
University essay from Uppsala universitet/Teoretisk astrofysikAbstract : Asymptotic Giant Branch (AGB) stars are stars with low- to intermediate mass in a late stage in their stellar evolution. An important feature of stellar evolution is the ongoing nucleosynthesis, the creation of heavier elements. READ MORE
