Subaru Telescope captures 1800 new supernovae

Astronomers using the Subaru Telescope identified about 1800 new supernovae in the distant universe, including 58 Type Ia supernovae over 8 billion light-years away. These findings will help elucidate the expansion of the ...

Seeds of giant galaxies formed in the early universe

Modern galaxies show a wide diversity, including dwarf galaxies, irregular galaxies, spiral galaxies, and massive elliptical galaxies. This final type, massive elliptical galaxies, provides astronomers with a puzzle. Although ...

Double or nothing—astronomers rethink quasar environment

Using Hyper Suprime-Cam (HSC) mounted on the Subaru Telescope, astronomers have identified nearly 200 "protoclusters," the progenitors of galaxy clusters, in the early universe, about 12 billion years ago, about ten times ...

Uncovering the origins of galaxies' halos

Using the Subaru Telescope atop Maunakea, researchers have identified 11 dwarf galaxies and two star-containing halos in the outer region of a large spiral galaxy 25 million light-years away from Earth. The findings, published ...

Minor merger kicks supermassive black hole into high gear

The galaxy Messier 77 (M77) is famous for its super-active nucleus that releases enormous energy across the electromagnetic spectrum, ranging from x-ray to radio wavelengths. Yet, despite its highly active core, the galaxy ...

Surface helium detonation spells end for white dwarf

An international team of researchers has found evidence that the brightest stellar explosions in our Universe could be triggered by helium nuclear detonation near the surface of a white dwarf star. Using Hyper Suprime-Cam ...
