New supernova analysis reframes dark energy debate

Wed, 13 Sep 17 00:01:10 -0700

The accelerating expansion of the Universe may not be real, but could just be an apparent effect, according to new research published in the journal Monthly Notices of the Royal Astronomical Society. The new study -- by a group at the University of Canterbury in Christchurch, New Zealand -- finds the fit of Type Ia supernovae to a model universe with no dark energy to be very slightly better than the fit to the standard dark energy model.



Ultraviolet light from superluminous supernova key to revealing explosion mechanism

Thu, 07 Sep 17 00:12:50 -0700

An international team of researchers led by Kavli IPMU's Alexey Tolstov and Ken'ichi Nomoto have discovered a way to use UV light from superluminous supernovae to uncover its explosion mechanism, and used it to identify Gaia16apd as a shock-interacting supernova, reports a new study.



Accretion-powered pulsar reveals unique timing glitch

Wed, 06 Sep 17 00:07:10 -0700

The discovery of the largest timing irregularity yet observed in a pulsar is the first confirmation that pulsars in binary systems exhibit the strange phenomenon known as a 'glitch.' The study is published in the journal Monthly Notices of the Royal Astronomical Society.



'Extreme' telescopes find the second-fastest-spinning pulsar

Tue, 05 Sep 17 00:09:30 -0700

By following up on mysterious high-energy sources mapped by NASA's Fermi Gamma-ray Space Telescope, a Netherlands-based radio telescope has discovered a new pulsar, the second fastest-spinning known.



UCLA physicists propose new theories of black holes from the very early universe

Fri, 01 Sep 17 00:05:50 -0700

'Primordial black holes,' believed to have formed shortly after the Big Bang, might explain how heavy elements such as gold, platinum and uranium came to be, UCLA physicists report.



Stellar corpse sheds light on origin of cosmic rays

Fri, 01 Sep 17 00:09:40 -0700

New research revealed that the entire zoo of electromagnetic radiation streaming from the Crab nebula -- one of the most iconic objects in the sky -- has its origin in one population of electrons and must be produced in a different way than scientists have traditionally thought. The results have implications for our understanding of how cosmic rays attain their incredible energies.



UChicago scientists detect first X-rays from mystery supernovas
A team of scientists, including scholars from the University of Chicago, appear to have found the first X-rays coming from type Ia supernovae. Their findings are published in the
