Explorers and Heliophysics Projects Division (EHPD)

The Explorers and Heliophysics Projects Division (EHPD) consists of three programs: Explorers, Living With a Star (LWS), and Solar Terrestrial Probes (STP). The Explorers Program is an uncoupled Program which provides frequent flight opportunities for world-class scientific investigations from space within NASA Heliophysics and Astrophysics Space Science goals. Explorers projects are typically implemented in the Principal Investigator (PI) mode. The LWS Program is a loosely coupled Program which provides missions to improve our understanding of how and why the Sun varies, how the Earth and Solar System respond, and how the variability and response affects humanity in Space and on Earth. The STP Program is an uncoupled Program which provides missions to understand the fundamental physics processes from the Sun to Earth, to outer planets, and beyond to the interstellar medium.

Suzaku, Herschel Link a Black-hole 'Wind' to a Galactic Gush of Star-forming Gas

Suzaku, Herschel Link a Black-hole ‘Wind’ to a Galactic Gush of Star-forming Gas

03.25.15 – By combining observations from the Japan-led Suzaku X-ray satellite and the European Space Agency's infrared Herschel Space Observatory, scientists have connected a fierce “wind” produced near a galaxy's monster black hole to an outward torrent of cold gas a thousand light-years across. The finding validates a long-suspected feedback mechanism enabling a supermassive black hole to influence the evolution of its host galaxy.

“This is the first study directly connecting a galaxy's actively ‘feeding’ black hole to features found at much larger physical scales,” said lead researcher Francesco Tombesi, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and the University of Maryland, College Park (UMCP). “We detect the wind arising from the luminous disk of gas very close to the black hole, and we show that it's responsible for blowing star-forming gas out of the galaxy's central regions.”
