title: How should I add an author subtitle under a chapter title?
body: <p>Had trouble knowing what exactly to Google, so I'll ask here.</p>
  
  <p>I'm typesetting a series of annotations to papers.  Each chapter will be on a paper, so I'd like to put the paper authors right under the chapter names (the paper titles).</p>
  
  <p>I can think of a hacky way of doing this, but I figured I'd ask the fine folks over at SO first for something more elegant / contribute to the knowledge base.</p>
