# How to add authors to a chapter title

I am writing my thesis using book as the document class. Just below every chapter title, I would like to add in small letters - a reference to the published paper of the chapter.

Something like

**Using Lineage for Sub-image Data Processing** %% chapter title
*Published as Author 1, Author 2, in XXX Journal , 2011*


Kindly guide me on how to create such an environment.

\documentclass[a4paper]{book}
\usepackage{xparse}
\NewDocumentCommand{\thesischapter}{o m m}{%
\IfNoValueTF{#1}
{\chapter[#2]{#2\origtitle{#3}}}
{\chapter[#1]{#2\origtitle{#3}}}%
}
\newcommand\origtitle[1]{\\
\parbox{\textwidth}{\normalsize\vspace*{2\baselineskip}#1}}

\begin{document}
\mainmatter
\thesischapter{Using Lineage for Sub-image Data Processing}
{Published as Author 1, Author 2, in XXX Journal , 2011}
Ciao
\chapter{A title}

Ciao
\end{document}
