Early publications about nonzero cosmological constant
  In 2011 the Nobel Prize in Physics was awarded for the 1998 discovery of the
nonzero cosmological constant. This discovery is very important and surely
worth to receive the Nobel Prize. However, years earlier several papers had
been published (Paal, Horvath, & Lukacs 1992; Holba et al. 1992, Holba et al.
1994) about a very similar discovery from observational data.
