This @LIGOLA Science Saturday celebrates 10 years since the first gravitational wave detection (GW150914)! Come visit @LIGO for tours, hands-on activities & interactive exhibits. This event is FREE doors open at 10 tours run every 1/2 hour until 2:30. #GravitationalWaves
We built some dither actuator coil boards this week. Dithering is a technique which applies small, controlled, oscillations to the mirrors and measuring the changes in the light in the interferometer. It allows precise alignment and locking of the cavities @LIGOLA

Hoy en el canal de YouTube comienzo una serie de clases sobre Relatividad General. Pero quiero hacer un curso que empiece por la misma base de qué es el espaciotiempo. Ir construyendo la estructura paso a paso. Es para los miembros del canal en el nivel Doctorado.

@duetosymmetry Those are sad news
Jorge Pullin retweeted
@ego_virgo @LIGOLA @LIGOWA @KAGRA_PR In our first 3 observing runs, we found 90 probable gravitational-wave signals. Analysis of the first part of our 4th observing run add 128 new probably signals, more than doubling our catalog! Analysis of the later parts of the run is underway 📈 arxiv.org/abs/2508.18080 #GWTC4
Jorge Pullin retweeted
Our fourth observing run has seen some of best detector performance. This allows us to see gravitational-wave signals from more distant sources and make more detections The timeline shows detections so far 📊 arxiv.org/abs/2508.18080 #GWTC4
Jorge Pullin retweeted
Results from the first part of our fourth LIGO @ego_virgo @KAGRA_PR observing run are out today! We're pleased to share the largest catalog of gravitational-wave observations with more discoveries of black holes and neutron stars 📰 arxiv.org/abs/2508.18082 #O4IsHere #GWTC4
We have several double suspensions we need to work on @LIGOLA
They say there are three kinds of houses in Louisiana: those that had termites, those that have termites and those that will have termites...
Installing the wires in the double suspensions is quite challenging. They are so thin that they are almost invisible against some of the metallic backgrounds. I had to borrow reading glasses in order to do it. @LIGO

Putting the final touches with Tábata Aira Ferreira and Danny Sellers to the scaffolding of the Allegro gravitational wave detector for its transportation to @LIGOLA
Started work on a balanced homodyne readout for LIGO. The first step was to classify the parts according to their materials in order to send them out for clean and bake. @LIGOLA
Worked on a double suspension @LIGOLA
We installed the side plates. The Bigger Beam Splitter is close to being finished @LIGOLA
Inserting the last beams into the scaffolding that will protect the Allegro gravitational wave detector on its trip to its final resting place @LIGOLA
