Magnetars are neutron stars with ultra-strong magnetic fields that are about a quadrillion times greater than the magnetic field of Earth. These huge magnetic...
Since the Big Bang, the early Universe had hydrogen, helium, and a scant amount of lithium. Later, some heavier elements, including iron, were forged in...
SGR 0501+4516 is the likeliest candidate in our Milky Way Galaxy for a magnetar that was not born in a supernova explosion as initially predicted; the...
The source of the newly-detected fast radio burst, FRB 20240209A, is in the distant outskirts of an ancient elliptical galaxy, which is located 2 billion...
New research provides the first conclusive evidence that a fast radio burst can originate from the magnetosphere, the highly magnetic environment immediately...
Fast Radio Bursts (FRBs) are millisecond-duration events detected from beyond our Milky Way Galaxy. FRB emission characteristics favor magnetars as their...
Swift J1818.0-1617 is located approximately 22,000 light-years away in the constellation of Sagittarius.
An artist’s impression of the magnetar Swift...
Neutron stars typically rotate at fast speeds, taking just seconds or even a fraction of a second to fully spin on their axis. However, a neutron star...
Using sensitive instruments onboard ESA’s International Gamma-Ray Astrophysics Laboratory (Integral) mission, astronomers have detected a gamma-ray burst...
Astronomers using CSIRO’s Parkes radio telescope (Murriyang) have detected unusual radio signals from XTE J1810-197, a radio magnetar (ultra-magnetic...
Fast radio bursts are extragalactic transient phenomena that shine in radio wavelengths for short durations lasting only 1-10 milliseconds. Some sources...
Using spectropolarimetric data gathered by various telescopes around the globe, astronomers from the University of Amsterdam and elsewhere have identified...
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...
Magnetars are neutron stars with ultra-strong magnetic fields, which can be observed in X-rays. Polarization measurements could provide information on...
Astronomers using the X-SHOOTER instrument at ESO’s Very Large Telescope (VLT) have detected light from a gamma-ray burst at a redshift of 6.3, meaning...
A fast radio burst (FRB) dubbed FRB 20191221A persists for up to three seconds, about 1,000 times longer than the average FRB; within this window, astronomers...
A pulsar wind nebula is created when the powerful magnetic field of a rapidly spinning neutron star accelerates surrounding charged particles to nearly...
FRB 190520 is only the second example of a repeating fast radio burst with a compact source of persistent radio emission between bursts.
An artist’s...
Radio-emitting neutron stars are objects with spin periods ranging from milliseconds to tens of seconds; as they age and spin more slowly, their radio...
