Blended Galaxies

galaxies-v01.jpg

Galaxies are merging all the time, even our own galaxy, the Milky Way. But how these mergers occur isn't entirely clear. University of Iowa astrophysicist Hai Fu will use a National Science Foundation grant to find and characterize supermassive black holes associated with merging galaxies.

Researchers Turn to “Citizen Scientists” for Help Identifying Gravitational Waves

Tyson-Littenberg.jpg

Dr. Tyson Littenberg, a research astrophysicist at NASA’s Marshall Space Flight Center and an adjunct professor in the Department of Space Science at The University of Alabama in Huntsville (UAH), is among a team of researchers who have launched "Gravity Spy," a crowdsourcing platform that tasks volunteer citizen scientists with sifting through LIGO data and identifying “families” of glitches that can be sorted by machine-learning algorithms.

New Limits in the Search for Sterile Neutrinos

HEP-2016-12-b-lrg.jpg

Sterile neutrinos could be part of the mysterious “dark world,” including the dark matter that makes up about a quarter of the universe. True evidence that sterile neutrinos exist would change our understanding of the universe. This study narrows the search for these particles.

A Multiple-Impact Origin for the Moon

Aharonson_moon1.jpg

Nearly a thousand computer simulations by the Weizmann Institute’s Prof. Oded Aharonson and his team produced results challenging the theory that the Moon was formed by a single massive collision; rather, the investigation shows, the more likely explanation is that multiple impacts produced many moonlets, which coalesced into our solitary satellite.

How Earth's Previous Moons Collided to Form the Moon

A new theory suggests the Moon we see every night is not Earth’s first moon, but rather the last in a series of moons that orbited our planet. Moons formed through the process could cross orbits, collide and merge, slowly building the bigger moon we see today.

Southampton Researchers Use High Energy X-Rays to Peer Beneath the Obscuring Skin of Growing Black Holes

A black hole studied and discovered by Peter Boorman, PhD researcher at the University of Southampton, is so hidden that it requires highly sensitive observations in the highest energy X-rays to classify it as obscured. But they give themselves away when material they feed on emits high-energy X-rays that NASA's NuSTAR (Nuclear Spectroscopic Telescope Array) mission can detect. That's how University of Southampton PhD researcher Peter Boorman used NuSTAR to recently identify a gas-enshrouded supermassive black holes located at the centres of nearby galaxy IC 3639 some 175 million light years from Earth.

Hubble Captures 'Shadow Play' Caused by Possible Planet

Astronomers were surprised to see a huge shadow sweeping across a disk of dust and gas encircling the nearby, young star TW Hydrae. They have a bird's-eye view of the disk, because it is tilted face-on to Earth, and the shadow sweeps around the disk like the hands moving around a clock. But, unlike the hands of a clock, the shadow takes 16 years to make one rotation. Hubble has 18 years' worth of observations of the star; therefore, astronomers could assemble a time-lapse movie of the shadow's rotation.

Hubble Detects 'Exocomets' Taking the Plunge Into a Young Star

Interstellar forecast for a nearby star: Raining comets! The comets are plunging into the star HD 172555, which resides 95 light-years from Earth. The comets were not seen directly around the star. Astronomers inferred their presence when they used NASA's Hubble Space Telescope to detect gas that is likely the vaporized remnants of their icy nuclei.

Research Supports Role of Supernovas in Measuring Pace at Which the Universe Expands

A team of research scientists led by David Cinabro, professor of physics and astronomy in the College of Liberal Arts and Sciences at Wayne State University, recently published a paper marking the importance of Type Ia Supernovas in measuring the pace at which the universe expands. Type Ia Supernovas are among the very brightest cosmic explosions visible, signaling the death of stars, and their importance to cosmology cannot be understated.

New research by cosmologists at the University of Chicago and Wayne State University confirms the accuracy of Type Ia supernovae in measuring the pace at which the universe expands. The findings support a widely held theory that the expansion of the universe is accelerating and such acceleration is attributable to a mysterious force known as dark energy.
