Since retiring as Professor of Physics in 2014, I have been a co-author of 47 manuscripts in refereed journals. Some were from work carried out before retirement, but most were new work resulting from a continuing collaboration with members of the Nuclear Physics Laboratory. This work was supported by funds from my discretionary account, funded by a return of overhead from several National Science Foundation grants I received.
In addition, I have published three books on Cosmology based on a course I originated in the late 80s to provide additional choices for non-science majors. This course is quite popular and has continued to be taught by others. It has grown from a one-semester course with a limit of 25 students to one that is now taught both semesters with roughly 100 students each term.
My latest book is part of a series on Astronomy and Cosmology published by the American Astronomical Society.
Elementary Cosmology (Second Edition): From Aristotle’s universe to the Big Bang and beyond
Here is a section from the preface:
This book began as a series of lecture notes for a one-semester course at the University of Notre Dame called “Elementary Cosmology.” An elective for non-science majors, it was designed to acquaint the non-mathematically-inclined student with the most important discoveries in cosmology up to the present day and how they have constantly altered our perceptions of the origin and structure of the universe. It examined such questions as: “Where did the universe come from?” or “Why do scientists now feel sure that its birth was in a great cosmic fireball called the Big Bang?” and “Where did the Big Bang itself come from?”
