In honor of the 10th anniversary of observing gravitational waves, I assembled this little video showing the observations over time. Come give a listen to the sound of the Universe!

Looking for multiband gravitational-wave sources in #LISA data - a needle in a haystack problem!
Shichao Wu presented a search for stellar origin binary black hole signals in LISA & next generation ground-based detectors (LISA+3G) with pyCBC.

Fun gravitational-wave news!
An neutron star - black hole merger was potentially just observed! ⚫⚪ The false alarm rate is ~ 1 per 25 years, so this will need further investigation. With luck, there may be electromagnetic emission from the collision.

Interested in the future of gravitational-wave astronomy?
Cosmic Explorer, the proposed US 40 km gravitational-wave observatories will observe millions of compact-binary mergers throughout the Universe and cosmic time.
CE will hopefully be joined by the Einstein Telescope and space-based LISA.

I guess all the scientists are moving over here? I don't really talk about much besides science.
Look out for updates on gravitational waves from me and my fantastic students. We study neutron stars and black holes with LIGO and are building tools for Cosmic Explorer and LISA.

What if there are highly spinning solar-mass scale binaries?
We report a search for gravitational waves from these unusual binaries, which might include unusual neutron stars, quark stars, hierarchical merger of primordial black holes, or other exotic scenarios.

Searches for gravitational waves from compact-binary mergers, which to date
have reported nearly 100 observations, have previously ignored binaries whose
components are both light ($< 2 M_\odot$)...
