ALMA spots twinkling heart of Milky Way

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found quasi-periodic flickers in millimeter-waves from the center of the Milky Way, Sagittarius (Sgr) A*. The team interpreted these blinks to be due ...

How galaxies and black holes grow together

Over the past two decades, astronomers have concluded that most, if not all, galaxies host massive black holes at their centers—and the masses of a black hole and its host galaxy are correlated. But how are the two connected? ...

Binary-driven hypernova model gains observational support

The change of paradigm in gamma-ray burst (GRBs) physics and astrophysics introduced by the binary driven hypernova (BdHN) model, proposed and applied by the ICRA-ICRANet-INAF members in collaboration with the University ...

Seeing the universe through new lenses

Like crystal balls for the universe's deeper mysteries, galaxies and other massive space objects can serve as lenses to more distant objects and phenomena along the same path, bending light in revelatory ways.

TRAPPIST-1 planetary orbits not misaligned

Astronomers using the Subaru Telescope have determined that the Earth-like planets of the TRAPPIST-1 system are not significantly misaligned with the rotation of the star. This is an important result for understanding the ...

Where neutrinos come from

Russian astrophysicists have come close to determining the origin of high-energy neutrinos from space. The team compared data on the elusive particles gathered by the Antarctic neutrino observatory IceCube and on long electromagnetic ...
