Abstract
The first part of this paper describes some observational characteristics of the supershells in the LMC and presents simple estimates of their evolutionary state, based on the supershell theory of MCCRAY ET AL. From the disagreement of theory with observations, possible implications for the phase structure of the ISM in the LMC are inferred.
In the second part, some results of the first application of standard statistical methods to a variety of high-resolution data on the LMC are presented. From an analysis of the two-dimensional autocorrelation and structure functions of HI, HII, radio continuum, IR emission and colour excess, we derive the scale properties of the emission regions and of turbulence in this galaxy. From the appearance of the supershells in the autocorrelation maps we conclude that they are most likely to dynamically influence the ISM in the LMC, in the sense that they produce the observed structures on the largest scales and trigger long term star formation.
