Research news on Galaxy winds

Galaxy winds as a research area investigates large-scale gaseous outflows driven by processes within galaxies, such as stellar feedback from massive stars and supernovae or energy and momentum injection from active galactic nuclei. This field focuses on the multi-phase structure, kinematics, and energetics of these winds, their impact on galaxy evolution, star formation regulation, metal enrichment of the circumgalactic and intergalactic media, and the closing of the baryon cycle. Research combines observational diagnostics across the electromagnetic spectrum with theoretical modeling and simulations to quantify mass-loading factors, escape fractions, and the coupling between radiation, cosmic rays, magnetic fields, and outflowing gas.

XRISM clocks hot wind of galaxy M82 at 2 million mph

For the first time, astronomers have directly measured the speed of superheated gas billowing from a cauldron of stellar activity at the heart of M82, a nearby galaxy undergoing an extraordinary burst of star formation. The ...

Magnetic superhighways discovered in a starburst galaxy's winds

Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has mapped a magnetic highway driving a powerful galactic wind into the nearby galaxy merger of Arp 220, revealing for the ...

ASKAP discovers a spectacular outflow in a nearby galaxy

Using the Australian Square Kilometer Array Pathfinder (ASKAP), an international team of astronomers has discovered a spectacular bipolar outflow from the disk of a nearby galaxy known as ESO 130-G012. The finding was reported ...

Flaring black hole whips up ultra-fast winds

Leading X-ray space telescopes XMM-Newton and XRISM have spotted a never-seen-before blast from a supermassive black hole. In a matter of hours, the gravitational monster whipped up powerful winds, flinging material out into ...

Hot gaseous outflow detected in the galaxy NGC 5746

Using ESA's XMM-Newton satellite, astronomers have conducted deep observations of a massive galaxy known as NGC 5746. As a result, they detected a hot gaseous outflow in the galaxy. The new findings, presented Oct. 1 on the ...

Hubble spots a magnetar zipping through the Milky Way

Magnetars are among the rarest—and weirdest—denizens of the galactic zoo. They have powerful magnetic fields and may be the source of fast radio bursts (FRBs). A team of astronomers led by European Space Agency researcher ...
