Astronomers using CSIRO’s Parkes radio telescope (Murriyang) have detected unusual radio signals from XTE J1810-197, a radio magnetar (ultra-magnetic...
A team of particle physicists from the University of Melbourne, the Australian National University, King’s College London and Fermi National Accelerator...
SN 1987A is the only supernova visible to the naked eye in the last 400 years and the most studied supernova in history. The event was a core-collapse...
Astronomers using CSIRO’s Australia Telescope Compact Array have captured the most detailed radio image ever seen of 47 Tucanae, the second brightest...
Neutron-star cores contain matter at the highest densities in our Universe. This highly compressed matter may undergo a phase transition where nuclear...
Removing the hydrogen-rich layers from a main sequence star exposes the helium-rich core. Such stripped helium stars are known at high and low masses,...
The rapid neutron capture process, or the so-called r-process, occurs in neutron-rich environments such as neutron star mergers or certain types of supernovae....
Spider pulsars are a type of millisecond pulsar that strips their companion stars of their atmospheres through energetic winds.
This composite image shows...
Astronomers have detected a mysterious and extremely bright event, named AT2022tsd, in a galaxy approximately 4.4 billion light-years away.
AT2022tsd is...
Using an array of ground and space-based telescopes, including the NASA/ESA/CSA James Webb Space Telescope, NASA’s Fermi Gamma-ray Space Telescope, and...
Fast radio bursts are extragalactic transient phenomena that shine in radio wavelengths for short durations lasting only 1-10 milliseconds. Some sources...
The millisecond pulsar PSR J1023+0038 is known to switch between two brightness modes almost constantly, something that until now has been an enigma.
This...
Using spectropolarimetric data gathered by various telescopes around the globe, astronomers from the University of Amsterdam and elsewhere have identified...
Fast radio bursts (FRBs) are brief flashes of radio waves from distant galaxies that are probably emitted by neutron stars. Some FRBs repeat, which enables...
Hercules X-1 is an X-ray binary system in which a neutron star is drawing material away from a Sun-like star. This neutron star’s accretion disk is unique...
Located 6,500 light-years away in the constellation of Taurus, the Crab Nebula and its pulsar formed in a supernova whose light reached Earth in July 1054.
This...
Magnetars are a special subset of the isolated neutron star family, with X-ray and radio emission mainly powered by the decay of their immense magnetic...
Princeton Plasma Physics Laboratory physicists Deepen Garg and Ilya Dodin say they can better understand the state of the cosmos shortly after the Big...
Astronomers have examined data about 700 short gamma-ray bursts (GRBs) detected with NASA’s Neil Gehrels Swift Observatory, Fermi Gamma-ray Space Telescope,...
