Quasar Outflows and Feedback Efficiency
Today’s paper presents the physical properties of outflows in type 2 quasars and their role in AGN feedback.
Red Dead Evolution
Most galaxies take significant fractions of the age of the universe to noticeably change. Others transform themselves in the first two billion years of the universe. How does this happen?
WARNING: Too much radiogenic heat could hurt exoplanet habitability
One-dimensional models show how the expected variability in radiogenic heat from U and Th in a rocky planet’s mantle could control the presence of a magnetic field and thus habitability.
Do We Have the Abell-ity to Find A Recoiling Black Hole in A2261-BCG?
What powers the core of the bright galaxy A2261-BCG? A massive black hole in the middle? A recoiling black hole? The authors of today’s paper use X-ray data to try to find out!

Around Half of Sun-Like Stars Could Host Potentially Habitable Worlds
A team of researchers from NASA’s Ames Research Centre, SETI and others have performed a statistical analysis on data from the Kepler Space Telescope and Gaia to estimate the occurrence rate of potentially habitable exoplanets around Sun-like stars.

UR: Constraining the Circumbinary Disk Tilt in the KH 15D system
In today’s undergraduate research post, the unusual brightness changes of the famous ‘Winking Star’ binary system is used to constrain properties of the disk that surrounds this intriguing system.
#BlackInPhysics week — meet the organisers
Last week was #BlackInPhysics week! We chat with the lead organisers Dr. Charles Brown, Dr. Eileen Gonzales and Dr. Jessica Esquivel to find out how it went.

Meet the AAS Keynote Speakers: Prof. Paola Caselli
Where did we come from? Where did we go? Astrochemistry can help answer the first question, at least… Find out more at Prof. Paola Caselli’s talk at #AAS236!
Meet the AAS Keynote Speakers: Prof James Lowenthal
Find out more about the challenges that satellite constellations, like SpaceX’s Starlink, pose to modern astronomy. Hear Prof James Lowenthal’s thoughts at his joint #AAS236 talk (with Prof Sandra Cruz-Pol) on Tuesday 2nd June at 12:40 pm (EDT).
Meet the AAS Keynote Speakers: Dr. Jo Dunkley
Hear from Jo Dunkley about the future of CMB observations as well as her journey into Academia at #AAS236.
