Smashing Results About Our Nearby Galactic Neighbors

An early result from the Survey of the Magellanic Stellar History (SMASH), carried out by an international team of astronomers using telescopes that include the Blanco 4-meter at Cerro Tololo Inter-American Observatory (CTIO) in Chile, suggests the the Magellanic Clouds are much bigger than astronomers calculated, and also have non-uniform structure at their outer edge, hinting at a rich and complex field of debris left over from their formation and interaction. Results were presented at the 225th meeting of the American Astronomical Society in Seattle, Washington.

The green circles in the image above show some of the DECam pointings of the SMASH survey, indicating the area where Magellanic Cloud stars have been found.

Compact Galaxy Groups Reveal Details of Their Close Encounters

A team including NOAO staff scientist Dr. David James has obtained spectacular images of some Compact Galaxy Groups with the Dark Energy camera on the Blanco 4-meter telescope at the Cerro Tololo Inter-American Observatory. This image of HCG 07 shows galaxies undergoing a burst of star formation.

NOAO Staff on team receiving the 2015 Breakthrough Prize in Fundamental Physics

The prize, for the unexpected discovery that the expansion of the universe is accelerating, rather than slowing as had been long assumed, is a shared honor with Saul Perlmutter, Brian Schmidt, and Adam Riess leading a collaboration of 51 total prize recipients splitting $3 million. Significant work on this project was done at the CTIO Blanco 4-meter telescope by current NOAO staff members Chris Smith and Tom Matheson, and former NOAO employees Bob Schommer, Nick Suntzeff, Mark Phillips, and Alejandro Clochiatti along with various other current and former AURA employees.

Infant Solar System Shows Signs of
Windy Weather

NOAO astronomer Colette Salyk has led a study using ALMA that suggests that the winds around some T Tauri stars may explain their unpredictable infrared glow.

HD100546 and Circumstellar Disk with Extrasolar Planet

In a recently published paper, NOAO astronomer Joan Najita was part of a team that has shown evidence for a planet forming in the disk around a young star. The results provide perhaps the first evidence that planets are surrounded by a circumplanetary disk at birth. This figure is an artist’s conception of the young massive star HD100546 and its surrounding disk. A planet forming in the disk has cleared the disk within 13 AU of the star, a distance comparable to that of Saturn from the sun. As gas and dust flows from the circumstellar disk to the planet, this material surrounds the planet as a circumplanetary disk (inset). These rotating disks are believed to be the birthplaces of planetary moons, such as the Galilean moons that orbit Jupiter.
