Schematic representation of the tilted accretion disk model. The black hole spin axis is assumed to be straight up and down in this illustration. The jet direction points almost perpendicular to the disk plane. The misalignment between the black hole spin axis and disk rotation axis triggers the precession of the disk and jet.

SPT-CL J2215-3537 resembles a blue cloud with a hazy golden light at its core. The cluster is set against the blackness of space, which is dotted with white, orange and blue specks of light. A combination of X-ray, ultraviolet, optical, and infrared light, was used to create the image. The blue cloud represents X-ray gas observed by NASA’s Chandra X-ray Observatory. The cloud is soft, and uniform in texture. Over time, galaxy clusters often merge or collide. These collisions cause disturbances and sharp features in a cluster’s gas. When a cluster takes on a smooth, calm appearance, as found here in SPT-CL J2215-3537, it indicates that no such collisions have occurred for a very long time. Astronomers call these galaxy clusters ‘relaxed.’ The hazy golden light at the heart of the cloud represents a massive central galaxy with a large amount of star formation. This central galaxy is quite isolated within the blue gas cloud. There are relatively few nearby specks of light near the central galaxy, and none are as bright or as large. No other large galaxies have been found within 600,000 light-years of the central galaxy. This implies that SPT-CL J2215-3537 has not experienced a galaxy merger in the last billion years.

This deep galaxy field from Webb’s Near-Infrared Camera (NIRCam) shows an arrangement of 10 distant galaxies marked by eight white circles in a diagonal, thread-like line. Two of the circles contain more than one galaxy. This 3 million light-year-long filament is anchored by a very distant and luminous quasar. Ccalled J0305-3150, this quasar appears in the middle of the cluster of three circles on the right side of the image. Image credit: NASA / ESA / CSA / Feige Wang, University of Arizona.

IXPE and Chandra images have been combined to show X-ray data of the area around Sagittarius A. The lower panel combines IXPE data, in orange, with Chandra data in blue. The upper panel depicts a much wider field-of-view of the center of the Milky Way. The thin white lines layered onto the top panel frame the highlighted area, and indicate that the perspective in the bottom panel has been rotated approximately 45 degrees to the right. The combination of IXPE and Chandra data helped the astronomers determine that the X-ray light identified in the molecular clouds originated from Sagittarius A* during an outburst approximately 200 years ago.
