Dr. McDowell's scientific publications include studies of the cosmological extragalactic background light and the possibility that massive black holes contribute to the dark matter problem; the X-ray emission from the merging galaxy Arp 220; the nature of the broad emission line region in quasars, and the broad-band spectral energy distrubtions of quasars. He helped design the CIAO data analysis package and the software infrastructure for the Chandra X-ray Observatory data processing pipelines.
Dr. Jonathan McDowell is also the editor of Jonathan's Space Report, a free internet newsletter founded in 1989 which provides technical details of satellite launches, and a contributing editor to Sky and Telescope Magazine. Dr. McDowell's web site provides the most comprehensive historical list of satellite launch information starting with Sputnik, and he carries out research on space history topics using original sources including declassified DoD documents and Russian-language publications.
The asteroid (4589) McDowell was named after him in 1993.
