Astrophysicists detect ultra-fast winds near supermassive black hole

New research led by astrophysicists at York University has revealed the fastest winds ever seen at ultraviolet wavelengths near a supermassive black hole.      

“We’re talking wind speeds of 20 per cent the speed of light, which is more than 200 million kilometres an hour. That’s equivalent to a category 77 hurricane,” says Jesse Rogerson, who led the research as part of his PhD thesis in the Department of Physics and Astronomy at York U. “And we have reason to believe that there are quasar winds that are even faster.”

Astronomers have known about the existence of quasar winds since the late 1960s. At least one in four quasars have them. Quasars are the discs of hot gas that form around supermassive black holes at the centre of massive galaxies - they are bigger than Earth’s orbit around the sun and hotter than the surface of the sun, generating enough light to be seen across the observable universe.

“Black holes can have a mass that is billions of times larger than the sun, mostly because they are messy eaters in a way, capturing any material that ventures too close,” says York University Associate Professor Patrick Hall, who is Rogerson’s supervisor. “But as matter spirals toward a black hole, some of it is blown away by the heat and light of the quasar. These are the winds that we are detecting.”

Rogerson and his team used data from a large survey of the sky known as the Sloan Digital Sky Survey to identify new outflows from quasars. After spotting about 300 examples, they selected about 100 for further exploration, collecting data with the Gemini Observatory’s twin telescopes in Hawaii and Chile, in which Canada has a major share.

“We not only confirmed this fastest-ever ultraviolet wind, but also discovered a new wind in the same quasar moving more slowly, at only 140 million kilometres an hour,” says Hall. “We plan to keep watching this quasar to see what happens next.”

Much of this research is aimed at better understanding outflows from quasars and why they happen.

“Quasar winds play an important role in galaxy formation,” says Rogerson. “When galaxies form, these winds fling material outwards and deter the creation of stars. If such winds didn’t exist or were less powerful, we would see far more stars in big galaxies than we actually do.”

The team’s findings were published today in the print edition of the Monthly Notices of the Royal Astronomical Society.

Solar System: Things to Know This Week

Our solar system is huge, let us break it down for you. Here are a few things to know this week:

1. The View from the Far Shore

Solar System: Things To Know This Week

The rugged shores of Pluto’s highlands come into sharp view in a newly released image from our New Horizons spacecraft. This latest view zooms in on the southeastern portion of Pluto’s great ice plains, where they border dark highlands formerly named Krun Macula.

2. Dawn’s Latest Light

Solar System: Things To Know This Week

Our Dawn mission has now completed more than 1,000 orbital revolutions since entering into Ceres’ gravitational grip in March 2015. The probe is healthy and performing its ambitious assignments impeccably. See what it has revealed lately HERE.

3. Counting Down

Solar System: Things To Know This Week

Our OSIRIS-REx mission to the asteroid Bennu is now entering the final preparations for its planned launch in September. In a new interview, the mission’s principal investigator reports on the final pre-flight tests happening at our Kennedy Space Center in Florida.

4. Deep Dive

Solar System: Things To Know This Week

Three successful engine maneuvers to bring the lowest part of the spacecraft’s orbit down to just 74 miles (119 km) above the surface of Mars, the MAVEN mission’s fifth deep dip campaign has begun. MAVEN is studying the planet’s atmosphere up close.

5. Storm Season

Solar System: Things To Know This Week

Meanwhile, other robotic Mars orbiters have revealed that a pattern of three large regional dust storms occurs with similar timing most Martian years. The seasonal pattern was detected from dust storms’ effects on atmospheric temperatures, which spacecraft have been monitoring since 1997.
