Star formation influenced by local environmental conditions

Fri, 15 Sep 17 00:10:20 -0700

Three scientists at Niels Bohr Institute (NBI), University of Copenhagen, have carried out extensive computer simulations related to star formation. They conclude that the present idealized models are lacking when it comes to describing details in the star formation process. 'Hopefully our results can also help shed more light on planet formation', says Michael Küffmeier, astrophysicist and head of the research team.



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.



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.



Magnetic fields in distant galaxy are new piece of cosmic puzzle

Wed, 30 Aug 17 00:16:00 -0700

Astronomers have measured magnetic fields in a galaxy 4.6 billion light-years away -- a big clue to understanding how magnetic fields formed and evolved over cosmic time.



Record-breaking galaxy 5 billion light-years away shows we live in a magnetic universe

Mon, 28 Aug 17 00:07:30 -0700

A team of astronomers has observed the magnetic field of a galaxy five billion light-years from Earth. The galaxy is the most distant in which a coherent magnetic field has been observed and provides important insight into how magnetism in the universe formed and evolved.



OU astrophysicist predicts detached, eclipsing white dwarfs to merge into exotic star

Fri, 18 Aug 17 00:09:10 -0700

A University of Oklahoma astrophysicist, Mukremin Kilic, and his team have discovered two detached, eclipsing double white dwarf binaries with orbital periods of 40 and 46 minutes, respectively. White dwarfs are the remnants of Sun-like stars, many of which are found in pairs, or binaries.



Astrophysicists explain the mysterious behavior of cosmic rays

Thu, 17 Aug 17 00:15:10 -0700

The model focuses mainly on the nature of Fermi bubbles and explains the spectral distribution of the observed cosmic rays flux. It can be said that the processes they described are capable of re-accelerating galactic cosmic rays generated in supernova explosions. Unlike electrons, protons have a significantly greater lifetime, so when accelerated in Fermi bubbles, they can fill up the volume of the Galaxy and be observed near the Earth.



International team of researchers redefines cosmic velocity web

Mon, 14 Aug 17 00:14:40 -0700

The cosmic web -- the distribution of matter on the largest scales in the universe -- has usually been defined through the distribution of galaxies. Now, a new study by a team of astronomers from France, Israel and Hawaii demonstrates a novel approach. Instead of using galaxy positions, they mapped the motions of thousands of galaxies.



Galactic winds push researchers to probe galaxies at unprecedented scale

Thu, 10 Aug 17 00:15:50 -0700

After using the Titan supercomputer at Oak Ridge National Laboratory to rule out a potential mechanism for galactic wind, UC Santa Cruz astrophysicist Brant Robertson and University of Arizona graduate student Evan Schneider, now a Hubble Fellow at Princeton University, are aiming to generate nearly a trillion-cell simulation of an entire galaxy, which would be the largest simulation of a galaxy ever.



Primordial black holes may have helped to forge heavy elements

Fri, 04 Aug 17 00:09:00 -0700

Astronomers like to say we are the byproducts of stars, stellar furnaces that long ago fused hydrogen and helium into the elements needed for life through the process of stellar nucleosynthesis.



Astronomers discover 'heavy metal' supernova rocking out

Mon, 31 Jul 17 00:01:20 -0700

A team of astronomers led by the Harvard-Smithsonian Center for Astrophysics has discovered that an extraordinarily bright supernova occurred in a surprising location. This 'heavy metal' supernova discovery challenges current ideas of how and where such super-charged supernovas occur. In the past decade, astronomers have discovered about 50 supernovas, out of the thousands known, that are particularly powerful. Following the recent discovery of one of these, the researchers have uncovered vital clues about where some of these extraordinary objects come from.



Astrophysicists map out the light energy contained within the Milky Way

Thu, 27 Jul 17 00:05:00 -0700

For the first time, a team of scientists have calculated the distribution of all light energy contained within the Milky Way, which will provide new insight into the make-up of our galaxy and how stars in spiral galaxies such as ours form. The study is published in the journal Monthly Notices of the Royal Astronomical Society.



Milky Way's origins are not what they seem

Wed, 26 Jul 17 00:01:40 -0700

In a first-of-its-kind analysis, Northwestern University astrophysicists have discovered that up to half of the matter in our Milky Way galaxy may come from distant galaxies. As a result, each one of us may be made in part from extragalactic matter. Using supercomputer simulations, the researchers found an unexpected mode for how galaxies acquired matter: intergalactic transfer. Supernova explosions eject copious amounts of gas from galaxies, causing atoms to be transported from one galaxy to another via powerful galactic winds.



Dark matter is likely 'cold,' not 'fuzzy,' scientists report after new simulations

Mon, 24 Jul 17 00:06:30 -0700

Scientists have used data from the intergalactic medium -- the vast, largely empty space between galaxies -- to narrow down what dark matter could be.



Infected insects cause a stink

Mon, 24 Jul 17 00:07:20 -0700

In a paper published today in Scientific Reports, a team led by Adler Dillman, assistant professor of parasitology in UCR's College of Natural and Agricultural Sciences, has shown how nematodes use smell to seek out uninfected insects, which they then enter and kill. The findings support the group's long-term goal of improving how gardeners and the agricultural industry use nematodes in biological pest management.



Superluminous supernova marks the death of a star at cosmic high noon

Fri, 21 Jul 17 00:06:30 -0700

The death of a massive star in a distant galaxy 10 billion years ago created a rare superluminous supernova, one of the most distant ever discovered. The brilliant explosion, more than three times as bright as the 100 billion stars of our Milky Way galaxy combined, occurred about 3.5 billion years after the big bang at a period known as 'cosmic high noon,' when the rate of star formation in the universe reached its peak.



Scientists discovered one of the brightest galaxies known

Fri, 14 Jul 17 00:14:30 -0700

Thanks to an amplified image produced by a gravitational lens, and the Gran Telescopio CANARIAS a team of scientists from the Polytechnic University of Cartagena and the Instituto de Astrofísica de Canarias have discovered one of the brightest galaxies known from the epoch when the universe had 20 percent of its present age.
