Light shed on a superluminous supernova which appears to have exploded twice

Researchers used the Gran Telescopio CANARIAS to observe a superluminous supernova almost from its occurrence, revealing surprising behavior including an initial increase in brightness followed by a decline and later stronger increase. The study sheds new light on these rare events, which are up to 100 times more energetic than Type 1a's.

Scientists begin modeling universe with Einstein's full theory of general relativity

Researchers use new computer codes to create accurate models of the universe and its contents, shedding light on the evolution of the universe and the growth of structure within it. The study confirms that small-scale structures produce significant effects on larger distance scales, providing new insights into gravity and cosmology.

Did gravitational wave detector find dark matter?

A Johns Hopkins team proposes a solution to the dark matter mystery by suggesting that black hole binaries detected by LIGO may be a signature of primordial black holes. The team's calculations match the predicted mass range for these mysterious objects, making them a plausible candidate for dark matter.

Bright dusty galaxies are hiding secret companions

Researchers found that hot dust in the distant universe is often caused by three or four galaxies instead of a single one. This study applied statistical methods to data from the Herschel Space Observatory and dropped the number of stars these galaxies have to be producing by a third.

New research shows quasars slowed star formation

A team of astronomers has found evidence that quasars' energy feedback may have slowed down star formation in the universe about 11 billion years ago. The study used data from multiple telescopes to detect the Sunyaev-Zel'dovich Effect, a phenomenon caused by high-energy electrons disturbing the Cosmic Microwave Background.

Explosive start not needed for fast radio bursts

A team of astronomers has found evidence of repeated fast radio bursts (FRBs) originating from the same location in the sky, contradicting the long-held assumption that these bursts are isolated events. This discovery rules out entire classes of theoretical models and suggests that the burst source can recharge in minutes.

Solved! First distance to a 'fast radio burst'

A team of scientists has confirmed that a 'fast radio burst' originates in the distant universe, using CSIRO radio telescopes and the National Astronomical Observatory's Subaru telescope. The breakthrough allows researchers to weigh the normal matter in the universe, confirming the presence of missing ordinary matter.

The turbulent birth of a quasar

Researchers used ALMA to study W2246-0526, the most luminous galaxy known, finding it's ejecting its star-forming gas due to intense infrared radiation. This turbulence could lead to the galaxy evolving into a traditional quasar.

VERITAS detects gamma rays from galaxy halfway across the visible universe

The VERITAS telescope detected powerful gamma rays from a distant galaxy, PKS 1441+25, revealing details about the black hole engine at its center. The gamma-ray emission was found to be located within the relativistic jet, but surprisingly far from the black hole, and is estimated to be around 5 light-years away.

Fast radio burst hints at its source

Researchers analyzed 700 hours of archival data to discover a burst of radio waves from six billion light years away. The region of space it came from was highly magnetized, suggesting it could be related to a supernova or nebula forming new stars.

Cosmological 'lost' lithium: An environmental solution

A new stellar model developed by researchers at SISSA reveals that cosmological 'lost' lithium in metal-poor stars was not destroyed, but rather accreted from the surrounding environment. The model, which agrees with observations, provides a plausible explanation for the low abundance of lithium-7 in ancient stars.
