Exploring the influence of galactic winds from a distant galaxy called Makani, UC San Diego’s Alison Coil, Rhodes College’s David Rupke and a group of collaborators from around the world made a novel discovery. Published in Nature, their study’s findings provide direct evidence for the first time of the role of galactic winds—ejections of gas from galaxies—in creating the circumgalactic medium…

How we discovered a glowing galactic ghoul
It’s a classic Halloween tale. A group of ghost hunters visit a grand old house that is rumored to be haunted. But after thoroughly exploring, they leave disappointed: there are no ghosts to be seen. Only later, when looking through their photographs of the place do they notice the mysterious apparition on the stairs. It was there all the time. Source:…

The nature of obscured active galactic nuclei
Most galaxies host a supermassive black hole (SMBH) at their nucleus, one whose mass exceeds a million solar-masses. When material actively accretes onto the SMBH, associated processes can produce an active galactic nucleus (AGN) with a hot torus and dramatic bipolar jets of rapidly moving charged particles. The most luminous known AGN emit over ten trillion solar-luminosities. Astronomers are trying to…
Milky Way raids intergalactic ‘bank accounts,’ Hubble study finds
Our Milky Way is a frugal galaxy. Supernovas and violent stellar winds blow gas out of the galactic disk, but that gas falls back onto the galaxy to form new generations of stars. In an ambitious effort to conduct a full accounting of this recycling process, astronomers were surprised to find a surplus of incoming gas.
