Context. Studies of the stellar and H I gas kinematics in dwarf low surface brightness (LSB) galaxies are essential for deriving constraints on their dark matter distribution. Moreover, a key component to unveil evolution LSBs is determine why some them can be classified as superthin. Aims. We aim investigate nature proto-typical superthin galaxy Fourcade-Figueroa (FF) understand role played by...

This is a very comprehensible review of some key issues in modern cosmology. Simple mathematical examples and analogies are used, whenever available. The starting point the well-known Big Bang cosmology (BBC). We deal with singularities appearing this theory discuss ways to remove them. Next, before introducing inflationary paradigm by means clear examples, we horizon flatness problems old BBC ...
