In a single decade, we have gone from the first-ever gravitational wave detection to several hundred of them. Every time there is a new possible detection, an alert is sent out, so observatories around the world can try to catch a…

The international LIGO-Virgo-KAGRA Collaboration reports the observations of two record-breaking events in gravitational wave observations. They were detected in October and November 2024, and they might be a crucial step forward in our…

Extreme-mass-ratio binary inspiralling in an environment of dark matter. The movement of small black holes creates a dense wake trail that slows it down, affecting the…
