Active galactic nuclei (AGN), powered by accreting supermassive black holes, and X-ray binaries (XRBs), powered by accreting neutron stars or stellar-mass black holes, are two representative classes of compact accreting systems. Relativistic collimated jets are among the most spectacular phenomena in these systems. Understanding how these powerful outflows are launched, accelerated, and collimated

The universe has been having fewer and fewer stellar "babies". Over the past 4.5 billion years, the rate of star birth has crashed to less than half of what it once was. But here's the twist: the most essential "fuel" for making stars has barely decreased. This finding comes from an international team led by researchers from the Chinese Academy of Sciences (CAS), in collaboration with the Dark Ene

Ahead of the scheduled Aug. 30 launch of NASA’s Nancy Grace Roman Space Telescope, several Washington University in St. Louis researchers have been selected to play important roles in the mission’s inaugural science program. The Roman telescope promises to transform our understanding of the universe. NASA will use the Roman telescope to investigate dark energy, discover thousands of exoplanets and

A research team from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences (CAS) has discovered that satellite galaxies retain a measurable "kinematic memory" of matter flowing into and along cosmic filaments. Using a large spectroscopic sample from the Sloan Digital Sky Survey (SDSS) , the team found that satellite galaxies preferentially orbit within planes that contain

Galaxy mergers are among the most spectacular and destructive events in the universe. During these encounters, not only are billions of stars redistributed, but the supermassive black holes lurking in the galaxies' centers can also interact with one another. Yet systems where three galaxies merge simultaneously are uncommon. Now, researchers have obtained the first direct observational evidence fo

The Large High Altitude Air Shower Observatory (LHAASO) revealed that the peculiar binary system Cygnus X-3 in the constellation Cygnus is the highest energy gamma-ray source known to date. The temporal variability and spectral characteristics measured by LHAASO confirmed this object as the source of cosmic rays, with particle energies reaching at least 30 PeV (1PeV=10 15 eV), far exceeding curren

The NSF-DOE Vera C. Rubin Observatory marked a major milestone with the beginning of the Legacy Survey of Space and Time (LSST), a 10-year effort to capture the universe in unprecedented detail. Lawrence Livermore National Laboratory (LLNL) engineer and former project manager for the LSST Camera, Vincent Riot reflected on the culmination of the project and the journey ahead. Development of the world's largest digital camera began before Riot arrived at the Lab in 2003. For most of his career, he worked to build first-of-its kind optical components, including lenses that would later be

Massive stars form within cold, dense molecular clouds, where gas contracts under gravity and can readily fragment into numerous smaller cores. A new study has revealed how massive stars avoid excessive fragmentation of their surrounding material and obtain sufficient "fuel" to sustain their growth.

A new study finds that the apparent "early galaxy crisis" suggested by recent James Webb Space Telescope (JWST) observations may not indicate a breakdown of the standard cosmological model. Instead, the phenomenon could result from a structural degeneracy in the interpretation of reionization observations.

A team of researchers has discovered that the winds generated by supermassive black holes are 100 times more powerful than previously thought, carrying energy across distances of approximately 300,000 light-years. The discovery demonstrates that these explosive winds impact the vast expanse of space beyond the galaxies they inhabit. "Black holes are largely known for sucking matter in, but they al
