Social media has become an important channel for publicizing academic research, which provides an opportunity for each scientific paper to become a hit. Employing a dataset of about 10 million tweets of 584,264 scientific papers from 2012 to 2018, this study investigates the differential diffusion of elite and non-elite journal papers (divided by Average journal impact factor percentile). We find that non-elite journal papers are diffused deeper and farther than elite journal papers, showing a diffusion trend with multiple rounds, sparse, short-duration and small-scale bursts. In contrast, the bursts of elite journals are characterized by a small number of persistent, dense and large-scale bursts. We also discover that elite journal papers are more inclined to broadcast diffusion while non-elite journal papers prefer viral diffusion. Elite journal papers are generally disseminated to many loosely connected communities, while non-elite journal papers are diffused to several densely connected communities.
