Nine unidentified Fermi–Large Area Telescope sources are likely pulsar wind nebulae; if verified, these discoveries will bring the number of known Fermi-detected pulsar wind nebulae from 12 to 21.
Diving deep into various instrumental systematics and data analysis options, a research team has found that the purported detection of biosignature gases in the atmosphere of K2-18b is disfavored.
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.
