Welcome to the blog page- A reservoir documenting hot-off-the-press quasar absorption line science, historical discoveries, short stories of quasar scientists (past and present), and thoughts about the future. I hope you will enjoy a read or two. Feel free to leave comments! Oh! ... and do not forget there is a Video Library that you can also browse on this site that also links to my Youtube channel: all things Quasar Absorption Lines.
Blogs are sorted in reverse date order. None of the writing nor grammar invokes AI or AI assistants; however, some research for the blogs relied on AI assistance.

Who were the obsessed scientists who transformed our science of astronomy, and just what were their contributions?
It took more than 30 years for quasar absorption line studies to mature into the science that the pioneers of the field always dreamed it could be. Faced with the cosmic quandary of the century, they ushered in an astronomy revolution. They made the discoveries, build the foundation, saw the possibilities, but never got to actually do the science of their dreams. That science really came to be possible starting in the late 1990s and early 2000s. In this blog, we honor the pioneers and the second generation of trailblazers. We offer brief biographies of these individuas with focus on their scienctific firsts and achievements.
Kellerman presents some historical facts that challenge the nominal origin story of quasars and highlight just how timid the most brilliant astronomers and quasar pioneers at the time were to equate quasars with extragalactic objects. He also describes the tensions and personalities involved in this high stakes game to find higher and higher redshift galaxies.

A Modern Scientific Revolution
Quasar and How they changed Our Science of the Cosmos
Before quasars, we were without the scientfic tools to probe the depths of time and space. We were without the ability to formulate testable ideas about the origin and evolution of the universe. Then quasars were discovered and they ushered in the modern age of astronomy. (This blog was originally written and appeared on the blog site "1584" hosted by Cambridge University Press.)

Quasar Pioneers Margaret and Geoffrey Burbidge and The First Book on Quasars
In 1967, only four years after quasi-stellar objects were discovered, Margaret and Geoffrey Burbidge had the audacity to write a 220 page book on the new astrophysical phenomenon of these mysterious objects. At the time, only some 100 qusars had been studied. What was clear was that astronomy was faced with a mystery that had no precedent in history--- these objects were nearly impossible to classify and understand. The thoroughness, insightfulness, and scientific honesty in these pages remains legacy science.
