Halo satellite will hunt for ‘missing’ normal matter

Studies of a early star uncover that 5 percent of all mass and appetite should be in normal matter—that is, a manifest things of a universe, composed of protons and neutrons.

However, when scientists supplement adult all a normal matter, a numbers don’t work out: About half of it is missing. One probable reason is that a blank matter exists in outrageous halos of prohibited gas surrounding galaxies.

Professor Philip Kaaret of a University of Iowa Physics and Astronomy Department is operative in partnership with a Goddard Space Flight Center to build a brick satellite that would use 3 tiny X-ray detectors to map a placement of prohibited gases compared with a Milky Way universe in sequence to exam this theory. The plan has perceived appropriation from NASA totaling $3.7 million.

The volume of gas a satellite finds can afterwards be extrapolated to other galaxies, beginning to residence a doubt of a blank normal matter.

Kaaret has been concerned with cube satellite investigate for several years. He constructed a deviation detector for a brick satellite built by a Radio Amateur Satellite Corporation (AMSAT) to magnitude a Van Allen belts, as good as a radio antennas commissioned on a roof of Van Allen Hall, that promulgate with brick satellites. This is his third try proposing a brick satellite plan for NASA.

“It takes some persistence,” Kaaret says. He perceived an email that he should call NASA domicile while during an astronomy assembly in Hawaii and says his greeting to being supposed was “great excitement.”

The plan has a four-year timeline, and a satellite is scheduled to launch in 2018. Kaaret says the timeline is ideal for students, who could stay on from start to finish, distinct many other projects in a department, that infrequently take as prolonged as 10 years to complete. Kaaret hopes to attract dual to 3 connoisseur students and 10–12 undergraduates to work on a plan over a march of a 4 years.

“They’ll be means to see a Milky Way in a whole new light,” he says.
