Dispu-tau-ble: When the Fog of Reionization Lifts, Mysteries Deepen
In today’s guest post, we explore if a small change in how we model the early universe could help solve issues in our understanding of dark energy and neutrinos.
What’s Going On in Galaxy Clusters?
There is a lot we don’t understand about the gas in galaxy clusters. Today’s paper provides new insight using a powerful X-ray space telescope!
Inclusive teaching practices help all students learn, but physicists are reluctant to change the way they teach
In today’s bite we discuss the use of inclusive teaching practices in physics classrooms and why physics professors are unlikely to implement more even though they help all students learn more effectively!
“Undressing” a Naked Quasar: HE0450-2958
Today’s guest post presents an investigation of HE0450-2958—a quasar with a “missing” host galaxy.
Quasars at Work: My photons come from a land where the accretion disks glow and the X-ray coronas plunder (energy from the disk)
In this exciting new paper, our authors show that in quasars, X-ray coronas fueled by energy stolen from the accretion disk around the black hole may be responsible for the interesting ultraviolet and optical emission we see!
If primordial black holes are dark matter, would we know?
Today’s paper explores the detectability of primordial black holes as a potential dark matter candidate.
