    The quest for axions
    We introduce the strong CP problem and the existence of the Axion as a possible solution. We discuss the possibility that axions are the dark matter of the...

    The relation between the most-massive star and its parental star cluster mass
    We present a thorough literature study of the most-massive star, mmax, in several young star clusters in order to assess whether or not star clusters are...
