Using NASA's Chandra spacecraft, astronomers have inspected X-ray emission from the center of a young radio galaxy known as NGC 3894. Results of this study, presented in a paper published June 24 on the arXiv pre-print server, ...
Using the Large High Altitude Air Shower Observatory (LHAASO), astronomers have performed a search for new high-energy gamma-ray sources. As a result, they have identified a new ultra-high energy gamma-ray source, which received ...
An international team of astronomers has conducted a detailed kinematic study of a radio galaxy known as 3C 84. The research sheds more light on the properties of this source and its connection to gamma-ray emission. The ...
In April 2019, scientists released the first image of a black hole in galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told.

Using NASA's Fermi Gamma-ray Space Telescope, Chinese astronomers have detected significant GeV gamma-ray emission from a supernova remnant (SNR) known as G272.2-3.2. The finding is detailed in a paper published March 29 ...
An enormous telescope complex in Tibet has captured the first evidence of ultrahigh-energy gamma rays spread across the Milky Way. The findings offer proof that undetected starry accelerators churn out cosmic rays, which ...

Using NASA's Fermi spacecraft, astronomers have conducted a long-term monitoring campaign of a blazar known as S5 1803+784 and have identified several gamma-ray and optical flares from this source. The finding is detailed ...
A large international team of researchers has proven that fragments of splitting atomic nuclei begin spinning after scission occurs during nuclear fission. In their paper published in the journal Nature, the group describes ...
Astronomers report the finding of a new candidate redback millisecond pulsar (MSP) binary associated with a gamma-ray source known as 4FGL J0940.3–7610. The newly found object is a short-period compact binary exhibiting ...
