    Study Notes

    Discovery of a Cosmic Beast

    • A supermassive black hole, located 300 million light-years from Earth in the galaxy SDSS1335+0728, is undergoing significant activity.
    • Astronomers observed this transition from dim to bright over four years, marking the first-ever real-time observation of such a change.
    • Findings were shared on June 18 in the journal Astronomy and Astrophysics.

    Active Galactic Nuclei (AGN)

    • AGNs are formed when supermassive black holes consume large amounts of matter, leading to a bright emission detectable across vast distances.
    • The black hole's brightness is caused by material heating up as it spirals into the black hole.

    Observation Techniques

    • The Zwicky Transient Facility (ZTF) scans the Northern sky every two days, using a wide-field camera situated at Palomar Observatory, California.
    • Scientists noticed SDSS1335+0728's brightness increase in December 2019, specifically in visible wavelengths.

    Extended Activity of SDSS1335+0728

    • An analysis of 20 years of historical data revealed no prior signs of activity in SDSS1335+0728, indicating an unprecedented occurrence.
    • Events where black holes consume stars typically last only days or months, yet this black hole remained active for years.

    Multispectral Observations

    • The Neil Gehrels Swift Observatory detected glowing X-rays from SDSS1335+0728 in February, alongside emissions in multiple wavelengths from other telescopes.
    • Data suggest this could be the formation of a new AGN.

    Ongoing Research and Future Prospects

    • The black hole may be consuming a smaller galaxy, but details remain unclear.
    • Future observations from NASA's James Webb Space Telescope and the Extremely Large Telescope in Chile aim to provide further insights on the behavior of gas around the black hole.
    • Researchers hope to clarify how AGNs form and the growth patterns of supermassive black holes.
