Exploring the Active Galactic Nuclei

The Active Galactic Nuclei Science Interest Group (AGN SIG) offers an opportunity for researchers across all career stages studying AGN to come together in a series of inspiring and focused talks given by leaders in the field, followed by informal discussions that can potentially lead to future collaborations

In addition, the AGN SIG organizes workshops and other collaborative activities aimed at advancing AGN science in alignment with NASA missions.

Dark lanes of dust and gas are scattered with red and white stars. The image has the step-shape format caused by the WFPC2 camera.
Galaxy NGC 4945 is similar in overall appearance to the Milky Way, but it contains a much more active supermassive black hole.

An illustration of Sun-like star HD 181327 and its surrounding debris disk. The star is at top right. It is surrounded by a far larger debris disk that forms an incomplete ellpitical path and is cut off at right. There’s a huge cavity between the star and the disk. The debris disk is shown in shades of light gray. Toward the top and left, there are finer, more discrete points in a range of sizes. The disk appears hazier and smokier at the bottom. The star is bright white at center, with a hazy blue region around it. The background of space is black. The label Artist's Concept appears at lower left.
