Distribution of astronomers' research impact quotient (riq) as function of field of specialization.

<p>Each field includes between 30 and 150 astronomers who began their career in the 1990s. The box-and-whisker plot of each field depicts the median (middle notch), lower and upper quartiles (lower and upper hinges), minimum and maximum values (lower and upper whiskers), and outliers.</p

Scatterplot of <i>m</i> vs. <i>riq</i>.

<p>Horizontal and vertical lines depict the global mean <i>m</i> and <i>riq</i>, respectively.</p

Frequency barplots of (a) subject domains for downloaded paper (rank-ordered), and (b) subject domains for Twitter-mentioned papers (rank-ordered).

<p>Temporal distribution plots of (c) total arXiv downloads (weekly), and (d) total Twitter mentions of arXiv papers in our cohort.</p

Response dynamics (Twitter mentions and arXiv downloads) for a selected arXiv preprint.

<p>As shown, for this particular example, Twitter mentions spikes shortly after submission and publication, and wane quickly with very mentions after the initial burst. ArXiv downloads peak shortly afterwards but continue to exhibit significant activity many weeks later.</p

Multi variant linear regression analysis of article citations vs. twitter mentions , article arXiv downloads , and time in days elapsed between beginning of our test period and submission of article, .
