The evolutionary paths of supermassive black holes and their host galaxies

A new paper entitled “Evolutionary Paths of Active Galactic Nuclei and Their Host Galaxies,” published on August 17, 2023, in Nature Astronomy, provides critical new insights on the co-evolution of supermassive black holes and their host galaxies. The tight correlations observed between the masses of supermassive black holes and the properties of their host galaxies have long intrigued astronomers. No consensus has been reached, however, on how the black hole-galaxy relations arose or how they evolved over time. The specific link between the black hole mass and the properties of host galaxies of AGNs in the nearby universe has remained elusive. The study found that galaxies with actively accreting black holes follow a similar relationship between black hole mass and stellar mass, regardless of galaxy type. Moreover, the position of a galaxy on this relation appears linked to the level of star formation and black hole accretion activity. "Our results unveil evolutionary trajectories for galaxies on the black hole mass-stellar mass plane," said Dr. Zhuang. “The joint evolution of the galaxy and its central black hole appears synchronized over long timescales. Galaxies that have overweight black holes catch up by making more stars. Those that have skinny black holes allow the black hole to eat more. In the end, the two reach a happy balance.”   The availability of a common gas supply for black hole accretion and star formation may account for the lockstep, synchronized growth of objects on the local relation. The evolutionary path of objects with undermassive black holes situated below the local relation supports a scenario suggested by recent simulations in which black hole growth initially lags behind star formation but later the situation reverses after the gas becomes stabilized at higher stellar mass.  AGNs with overmassive black holes above the local relation continue to gain stellar mass, consistent with the detection of active star formation and abundant gas content in early-type AGN host galaxies. These trajectories suggest that radiative-mode AGN feedback mechanisms, which are expected to suppress star formation, are less effective for galaxies below the scaling relation. For galaxies above the relation, kinetic-mode feedback appears insufficient to halt long-term star formation. "This work provides new insights on the coevolution of supermassive black holes and their host galaxies that can serve as the definitive benchmark and framework for evolutionary studies," highlighted Prof. Ho. "The results offer critical observational constraints for numerical simulations modeling the complex interplay between black holes and their host galaxies." “This article explores the evolutionary paths of galaxies on the black hole mass–stellar mass plane in the nearby Universe, linking the properties of star formation and black hole accretion and providing critical constraints for active galactic nuclei feedback,” the editor of Nature Astronomy highly commends. “The findings in this paper are extremely interesting and are quite important for our understanding of black hole and galaxy co-evolution across cosmic times and their star formation and accretion,” says one of the reviewers.

JWST's Stunning Images of the Ring Nebula 🌌

🔭 The James Webb Space Telescope (JWST) has done it again! Prepare to be awestruck as this groundbreaking telescope captures breathtaking new images of the iconic Ring Nebula, also known as Messier 57. Led by a team of international astronomers, including brilliant minds from the University of Manchester, these images reveal the nebula's intricate and ethereal beauty like never before!

🌟 For sky enthusiasts, the Ring Nebula is a well-known object visible all summer long, residing in the constellation Lyra. A small telescope will already showcase its characteristic donut-like structure of glowing gas, giving this celestial wonder its name.

Webb reveals new structures within iconic supernova

NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987. New observations by Webb's NIRCam (Near-Infrared Camera) provide a crucial clue to our understanding of how a supernova develops over time to shape its remnant.

This image reveals a central structure like a keyhole. This center is packed with clumpy gas and dust ejected by the supernova explosion. The dust is so dense that even near-infrared light that Webb detects can't penetrate it, shaping the dark "hole" in the keyhole.

A bright, equatorial ring surrounds the inner keyhole, forming a band around the waist that connects two faint arms of hourglass-shaped outer rings. The equatorial ring, formed from material ejected tens of thousands of years before the supernova explosion, contains bright hot spots, which appeared as the supernova's shock wave hit the ring. Now spots are found even exterior to the ring, with diffuse emission surrounding it. These are the locations of supernova shocks hitting more exterior material.

While these structures have been observed to varying degrees by NASA's Hubble and Spitzer Space Telescopes and Chandra X-ray Observatory, the unparalleled sensitivity and spatial resolution of Webb revealed a new feature in this supernova remnant—small crescent-like structures.

These crescents are thought to be a part of the outer layers of gas shot out from the supernova explosion. Their brightness may be an indication of limb brightening, an optical phenomenon that results from viewing the expanding material in three dimensions. In other words, our viewing angle makes it appear that there is more material in these two crescents than there actually may be.

The high resolution of these images is also noteworthy. Before Webb, the now-retired Spitzer telescope observed this supernova in infrared throughout its entire lifespan, yielding key data about how its emissions evolved over time. However, it was never able to observe the supernova with such clarity and detail.

Despite the decades of study since the supernova's initial discovery, there are several mysteries that remain, particularly surrounding the neutron star that should have been formed in the aftermath of the supernova explosion. Like Spitzer, Webb will continue to observe the supernova over time.

Its NIRSpec (Near-Infrared Spectrograph) and MIRI (Mid-Infrared Instrument) instruments will offer astronomers the ability to capture new, high-fidelity infrared data over time and gain new insights into the newly identified crescent structures. Further, Webb will continue to collaborate with Hubble, Chandra, and other observatories to provide new insights into the past and future of this legendary supernova.
