The third Gravitational-Wave Transient Catalog (GWTC-3) describes signals detected with
Advanced LIGO and Advanced Virgo up to the end of their third observing run. Updating the …

The discovery of the electromagnetic counterpart to the binary neutron star (NS) merger
GW170817 has opened the era of gravitational-wave multimessenger astronomy. Rapid …

On 2019 August 14, the LIGO and Virgo Collaborations detected gravitational waves from a
black hole and a 2.6 solar mass compact object, possibly the first neutron star–black hole …

With the conclusion of the third observing run for Advanced LIGO/Virgo (O3), we present a
detailed analysis of both triggered and serendipitous observations of 17 gravitational-wave …

We address the problem of optimally identifying all kilonovae detected via gravitational-
wave emission in the upcoming LIGO/Virgo/KAGRA observing run, O4, which is expected to …

Context. Large-scale astronomical surveys such as the Zwicky Transient Facility (ZTF)
opened a new window of opportunity in the search for rare astrophysical phenomena …

We present the S-PLUS Transient Extension Program (STEP): a supernova and fast
transient survey conducted in the southern hemisphere using data from the Southern …

We present a comprehensive analysis of 653 optical candidate counterparts reported during
