Not research per se, but I do read, as do most with an interest in early Christianity. The following are some suggested physical books for those interested:
Marcion: The Gospel of the Alien God, 1921, ISBN 1556357036
Marcion: On the Restitution of Christianity, 1934, ISBN 149829359X
The First New Testament: Marcion's Scriptural Canon, 2013, ISBN 1598151312
