Fascinating LUTh seminar! Debarati Chatterjee shows how gravitational waves let us peer inside neutron stars to study ultra-dense matter — connecting nuclear theory, heavy-ion experiments and astrophysics. A must-watch for anyone curious about extreme physics! #GravitationalWaves #NeutronStars #DenseMatter #Astrophysics #NuclearPhysics #MultiMessenger #Science #English

🖥️ The researchers used the distributed volunteer computing project @einsteinathome and the @maxplanckgesellschaft's computing clusters Atlas, Raven, and Viper to analyze public data from the @LIGO detectors’ third observing run (O3).

🔍 They found all hardware injections — signals added artificially to the data by moving the LIGO mirrors — within the search range, and were the first ever to successfully detect the hardware injection no. 11.

🚀 While no astrophysical signals were observed, the team expects their O3 results to be competitive with LIGO-Virgo-KAGRA analyses based on yet unpublished data from the latest, fourth observing run (O4) data.

✨ New selected research highlight ✨

Einstein@Home conducts most sensitive search for elusive continuous gravitational waves.

✨ Astronomers expect the Galactic population of neutron stars – compact remnants of supernova explosions – to be a promising source of continuous gravitational waves, which have yet to be detected.

🔭 Since the sky positions, spin frequencies, and frequency derivatives of individual neutron stars are unknown, wide-band, all-sky searches are one of the main tools used in the field. Researchers from the independent @maxplanckgesellschaft research group “Continuous Gravitational Waves” at the @mpi_grav have recently published the deepest all-sky search for continuous gravitational waves to date.

There were already two new gravitational-wave candidates today – so far.

S250830m, if real, most likely came from a merger of two black holes 12 billion light-years away.

ℹ️ https://gracedb.ligo.org/superevents/S250830m/view/

S250830bp, if real, came either from a merger of two black holes (84% probability) or from a merger of a black hole with a neutron star (16% probability). The distance is “only” 1.4 billion light-years. The sky position could be determined quite accurately (to within 10.5 square degrees).
