Illustrating the Discovery of Pulsar PSR J1728–4608, a Recently Classified "Redback" Pulsar. This neutron star features an ultra-fast spin of 2.86 milliseconds and a tight orbit, completing a revolution around its companion in just 5.05 hours. Eclipsed for 42% of its orbit, the pulsar remains hidden from view for significant portions of its journey.

What if a galaxy could exist without the brilliant stars that normally make galaxies visible?

What if a galaxy could exist without the brilliant stars that normally make galaxies visible? Cloud-9 may offer astronomers one of the most intriguing examples yet. Located near the spiral galaxy M94, this mysterious hydrogen-rich object appears to contain enormous amounts of gas while producing almost no detectable starlight.

"ASTRID: An advanced simulation powered by the Frontera supercomputer models 13.5 billion years of cosmic evolution, decoding the timeline from the cosmic dawn to the present. The project reveals the co-evolution of black holes and galaxies across 816 million light-years, using 166 billion particles and generating 30 terabytes per snapshot to trace the formation of the universe and predict gravitational waves."

Astrophysicists have completed ASTRID, the largest cosmological hydrodynamic simulation ever run

Astrophysicists have completed ASTRID, the largest cosmological hydrodynamic simulation ever run, tracing the universe from the cosmic dawn ($z=99$) down to the present day ($z=0$). By resolving 166 billion particles across 815 million light-years, ASTRID unveils how supermassive black holes co-evolve with galaxies and sculpt the cosmic web.

New evidence from the GW200105 event reveals a neutron star and black hole merging on an eccentric orbit, challenging established circular models. The findings suggest a crowded cosmic origin, resulting in a black hole 13 times the sun's mass.

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together while orbiting in an oval path

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together while orbiting in an oval path, challenging long-standing assumptions about cosmic pair formation. Most neutron star-black hole pairs are expected to adopt circular orbits long before merging, their orbits slowly rounded out by the constant emission of gravitational waves over millions of years.
