Since early this morning, there have been two new gravitational-wave candidates.

S250904ae, if real, most likely originated from a merger of two black holes at a distance of around 11 billion light-years.

The sky position could be constrained to an area of around 1000 square degrees.

S250904br, if real, most likely originated from a merger of two black holes at a distance of around 9 billion light-years.
