Study: Pair of Distinct Black Hole Mergers Reveals Clues on How They Form and Evolve
The mergers, measured one month apart in 2024 by LIGO-Virgo-KAGRA collaboration, advance scientific understanding of the nature of black hole formation and fundamental physics; offer evidence of "seco...

New paper from
@ligo.org
,
@egovirgo.bsky.social
and KAGRA announcing the observation of a pair of Binary Black Holes, with big implications for their formation history as well as big impact on our understanding of fundamental physics in our Universe. Contributions from NCfA member Cael Haster.

GW231109_235456: A Sub-threshold Binary Neutron Star Merger in the LIGO-Virgo-KAGRA O4a Observing Run?
We present a sub-threshold search for gravitational-wave inspirals from binary neutron stars using data from the first part of the fourth observing run of the LIGO-Virgo-KAGRA Collaboration. To enhanc...

Hubble constant constraint using 117 FRBs with a more accurate probability density function for ${\rm DM}_{\rm diff}$
Fast radio bursts (FRBs) are among the most mysterious astronomical transients. Due to their short durations and cosmological distances, their dispersion measure (DM) - redshift ($z$) relation is usef...
