Are ring galaxies the ancestors of giant low surface brightness galaxies?
M. Mapelli, B. Moore, E. Ripamonti +4
Giant low surface brightness galaxies (GLSBs) have flat discs extending up to ~100 kpc. Their formation is a puzzle for cosmological simulations in the cold dark matter scenario. W…
The origin of lopsidedness in galaxies
M. Mapelli, B. Moore, J. Bland-Hawthorn
It has long been known that a large fraction of disc galaxies are lopsided. We simulate three different mechanisms that can induce lopsidedness: flyby interactions, gas accretion f…
Primordial gas heating by dark matter and structure formation
M. Mapelli, E. Ripamonti
Dark matter (DM) decays and annihilations might heat and partially reionize the Universe at high redshift. Although this effect is not important for the cosmic reionization, the ga…
Constraining DM through 21 cm observations
M. Valdes, A. Ferrara, M. Mapelli +1
Beyond reionization epoch cosmic hydrogen is neutral and can be directly observed through its 21 cm line signal. If dark matter (DM) decays or annihilates the corresponding energy…
