#s251014cn — Public Fediverse posts

There were two new probable gravitational-wave events in the past two days. If they are real, both came from mergers of binary black holes.

1️⃣ S251013x on 13 October at a distance of around 12 billion light-years. If the masses of the two black holes were equal, they were between around 25 and 100 solar masses. More info: https://gracedb.ligo.org/superevents/S251013x/view/

2️⃣ S251014cn on 14 October at a distance of around 2 billion light-years. If the masses of the two black holes were equal, they were between around 6 and 25 solar masses. More info: https://gracedb.ligo.org/superevents/S251014cn/view/

Es gab gestern und vorgestern jeweils ein neues Gravitationswellen-Ereignis. Beide stammen, wenn sie echt sind, von Verschmelzungen von Paaren Schwarzer Löcher.

1️⃣ S251013x am 13.10. in einer Entfernung von rund 12 Milliarden Lichtjahren. Wenn die Massen der beiden Schwarzen Löcher gleich groß waren, lagen sie zwischen rund 25 und 100 Sonnenmassen. Mehr Infos: https://gracedb.ligo.org/superevents/S251013x/view/

2️⃣ S251014cn am 14.10. in einer Entfernung von rund 2 Milliarden Lichtjahren. Wenn die Massen der beiden Schwarzen Löcher gleich groß waren, lagen sie zwischen rund 6 und 25 Sonnenmassen. Mehr Infos: https://gracedb.ligo.org/superevents/S251014cn/view/

This afternoon's #GravitationalWave candidate #S251014cn

If real, the source is probably a binary black hole (chirp mass ~11–22 solar masses)
