An investigation of the evolution of fast radio bursts with redshift found similarities in the properties of fast radio bursts and short gamma-ray bursts, suggesting that fast radio bursts might arise from magnetars.
A galactic superwind appears to be the source of two giant bubbles stretching thousands of light-years from the center of a starburst galaxy, though an active galactic nucleus could also be the cause.
A new catalog of 9,482 dust-lane spheroidal galaxies reveals that these galaxies are significantly redder and have higher specific star-forming rates than non-dust-lane spheroidal galaxies
Researchers find that a shocked cocoon of a collapsar-driven jet choked in an extended circumstellar medium is the most plausible model to explain a supernova that was associated with a fast X-ray transient.
What at first appeared to be single group of stars with similar origins is now known to be three separate groups of stars that have converged at the same location from very different areas in our galaxy.
GRB 211211A is a long-duration gamma-ray burst without an associated supernova; its cause is still unknown, and now researchers have shown that a white dwarf–neutron star merger is a possible source.
