Is This Black Hole Finally Ending Its 34-Year Outburst?
A decades-long black-hole outburst is fading, but thick gas hides its X-rays. Radio clues suggest quiescence—not a settled verdict.
A Black Hole Census Could Reveal the Growth Rules No One Can See
A statistical-physics framework could turn black-hole population snapshots into clues about how these cosmic objects grow across time.
The Black Hole Count That Shrinks as Its Building Blocks Multiply
In ABJM theory, smaller k unlocks more monopole operators yet may leave fewer black-hole states, as trace relations erase seemingly new possibilities.
A Cosmic Gas Cocoon Could Grow Black Holes Faster Than Expected
Could Little Red Dots hide black holes inside giant gas envelopes? New models suggest a fast-growth path—and winds that may end it.
