NGC 6861 is a lenticular galaxy located in the constellation Telescopium. It is the second-brightest object in the constellation. Unlike most lenticular galaxies, which tend to be mostly devoid of both gas and dust, NGC 6861 exhibits a thick obscuring ring of dust around the nucleus where star formation is occurring.

2023年7月25日 · NGC 6861. Galaxy NGC 6861 features a prominent disk of dark bands circling its center. These bands are a result of large clouds of dust particles obscuring the light emitted by the stars behind them. These dust lanes are useful for working out whether we are seeing the galaxy disc edge-on, face-on or, as is the case for NGC 6861, somewhat in ...

2010年2月23日 · We discuss supersonic infall of the NGC 6861 subgroup, sloshing from the NGC 6868 and NGC 6861 subgroup merger, and AGN heating as possible explanations for these features, and discuss possible scenarios that may contribute to the order of magnitude discrepancy between the Margorrian and black hole mass–σ predictions for its central black hole.

2015年1月16日 · This NASA/ESA Hubble Space Telescope view shows some important details of NGC 6861. One of the most prominent features is the disk of dark bands circling the centre of the galaxy. These dust lanes are a result of large clouds of dust particles obscuring the light emitted by the stars behind them.

2023年11月15日 · The subject of this image is NGC 6861, a galaxy discovered in 1826 by the Scottish astronomer James Dunlop. Almost two centuries later we now know that NGC 6861 is the second brightest member of a group of at least a dozen galaxies called the Telescopium Group — otherwise known as the NGC 6868 Group — in the small constellation of ...

2020年1月11日 · (NGC 6861) of ∼414 km s−1, a factor of 1.6 greater than the 250 km s−1 central stellar velocity dispersion of the more lumi-nous elliptical galaxy NGC 6868. We summarize the galaxy properties and estimates of the central black …

2022年6月17日 · We present Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 2 observations of CO (2-1) emission from the circumnuclear disks in two early-type galaxies, NGC 1380 and NGC 6861. The disk in each galaxy is highly inclined (), and the projected velocities of the molecular gas near the galaxy centers are in NGC 1380 and in NGC 6861.

2023年9月15日 · NGC 6861 is a very rarely imaged lenticular galaxy located 129 million light years away in the constellation Telescopium. The galaxy is quite small in the field of view but has an interesting disk of dark dust bands at the center of the galaxy.
