An international team of astronomers has inspected an unusual superluminous supernova known as SN 2020wnt. Results of the study suggest that this supernova is slowly evolving and carbon-rich. The finding was detailed in a ...
By analyzing the historical light curve of blazar PKS 0405-385 from NASA's Fermi spacecraft, Chinese astronomers have detected quasi-periodic oscillation from this source. The discovery, presented in a paper published May ...
Researchers from The Australian National University (ANU) have found an alternative explanation for a mysterious gamma-ray signal coming from the center of the galaxy, which was long claimed as a signature of dark matter.

Using various space and ground-based observatories, astronomers have inspected flaring activity observed on a blazar known as S5 1803+78. Results of this multi-wavelength study, published April 10 on the arXiv pre-print server, ...
Light on, light off—this is how one could describe the behavior of the nova, which goes by the name RS Ophiuchi (RS Oph). Every 15 years or so, a dramatic explosion occurs in the constellation of the Serpent Bearer. Birthplaces ...
