Early publications about nonzero cosmological constant

TL;DR

This paper discusses early observational studies on the nonzero cosmological constant, highlighting that significant findings predated the 2011 Nobel Prize-winning discovery.

Contribution

It emphasizes the importance of earlier publications that identified the nonzero cosmological constant before the Nobel-winning work.

Findings

Early papers in 1992 and 1994 discussed nonzero cosmological constant

These studies used observational data similar to later discoveries

The recognition of prior work highlights the timeline of cosmological research

Abstract

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.
