"Hubble Telescope Uncovers Rare Radio Galaxy with Luminous Heart"

NASA's Hubble Space Telescope has captured a stunning image of lenticular galaxy NGC 612, which is an active galaxy with a supermassive black hole at its center. The galaxy's central region is incredibly energetic, spewing out jets of gas at nearly the speed of light and outshining the combined light of every star in the galaxy. NGC 612 is also a Seyfert galaxy, emitting large amounts of infrared radiation. This rare non-elliptical galaxy is believed to have had a past interaction with a companion spiral galaxy, and it is one of only five known radio-emitting lenticular galaxies.

Discovery of Eclipsing Absorber Sheds Light on NGC 6814's Active Galaxy

Astronomers have discovered a composite eclipsing absorber in the active galaxy NGC 6814, responsible for a distinct X-ray eclipse event. The absorber is a clumpy, multi-phase cloud cluster, possibly part of the disk "wind" launched from the inner region of the accretion disk. The research team used a flux-color plot to analyze the eclipse event and revealed the presence of Compton-thick absorption, previously unnoticed in the spectra. This study highlights the importance of X-ray occultation events in understanding the gas surrounding supermassive black holes.

Spanish astronomer makes groundbreaking discovery: A galaxy within a galaxy and a new active galaxy

An astronomer in Spain has discovered a new active galaxy, tentatively named the Iris Galaxy, within the Sombrero Galaxy by analyzing images from the Hubble Space Telescope. The Iris Galaxy appears to have two spiral arms and may possess an active galactic nucleus (AGN) at its center, indicating the presence of star formation or a supermassive black hole. If the Iris Galaxy is bound to the Sombrero Galaxy's gravity, it would be a small galaxy around 1,000 light-years in size. However, if it is not bound, it could be much larger and located around 65 million light-years away.

"Spanish Astronomer Unveils Active Galaxy Breakthrough"

Spanish astronomer Elio Quiroga Rodriguez has discovered a peculiar object in the Sombrero Galaxy, identified as a galaxy hosting an active galactic nucleus (AGN). By analyzing Hubble Space Telescope images, Rodriguez found that the object, previously classified as a globular cluster candidate, may be a barred spiral galaxy with an AGN at its center. The newfound galaxy, cataloged as PSO J190.0326-11.6132, has a radial velocity suggesting it could be a satellite of the Sombrero Galaxy. Further observations are needed to determine the type of AGN present in the galaxy.
