Blowing the Cover of a Hidden Black Hole

The nearby galaxy NGC 7582 is an extreme example of an “obscured AGN”, a galaxy with an accreting supermassive black hole that is deeply enshrouded in gas and dust. New observations show that the black hole launches a powerful wind, which is confined by a rotating ring of gas and dust 2000 light years in diameter. The ring also contributes to the extreme obscuration of the black hole. The results, reported by a team led by NOAO astronomer Stephanie Juneau, lend new insights into the interaction between black holes and their host galaxies.

Punching Above Its Weight, a Brown Dwarf Launches a Parsec-Scale Jet

Astronomers using the SOAR telescope at CTIO have discovered a spectacular extended jet from a young brown dwarf. While young stars are known to launch jets that extend over a light year or more, this is the first such jet from a brown dwarf. The discovery, made by a team that includes NOAO astronomers Cesar Briceno and Steve Heathcote, lends new insight into how substellar objects form.

Meet “DeeDee”, a Distant Dwarf in the Outer Solar System

Located 92 AU from the Sun, DeeDee is the second most distant trans-Neptunian object known — only the dwarf planet Eris is further away. Discovered in the Dark Energy Survey, which is being carried out at CTIO, DeeDee is petite, with a diameter ¼ that of Pluto. DeeDee was discovered by an international team, including NOAO astronomers Alistair Walker and Tim Abbott.

Dusk to Dawn time-lapse at CTIO

While observing for the DECam Legacy Survey (DECaLS), Rongpu Zhou (University of Pittsburgh) set up a camera to capture a time-lapse of the evening. For the first 18 seconds of the video, the moon illuminates the foreground as if it were daylight, while the night sky rotates overhead. As the moon sets, many more stars become visible, and our galaxy, the Milky Way, rises as the Magellanic Clouds set behind the Blanco 4m Telescope. The time-lapse was taken on 4 March 2017.

NOAO Newsletter

The March 2017 NOAO Newsletter is online and ready to download. It contains sections on Science Highlights, Community Science & Data, System Observing: Telescopes and Instruments, and NOAO Operations & Staff.

On the Cover
NOAO is developing tools for the astronomical community to enable research using big datasets from multiple sources. The cover image is the first panel of “Tales of the Modern Astronomer: Boom Goes the Night,” which tells the story of a young researcher who uses tools such as ANTARES to find the optical afterglow of a gravitational wave detection by combining LIGO with the LSST alert stream to identify optical afterglow candidates that can be followed up with telescopes such as Gemini and the Blanco 4mtelescope using the Dark Energy Camera.
