F. Acernese, M. Agathos, K. Agatsuma +231
Advanced Virgo is the project to upgrade the Virgo interferometric detector of gravitational waves, with the aim of increasing the number of observable galaxies (and thus the detec…
Constraints on cosmic strings using data from the third Advanced LIGO-Virgo observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1586
We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 data set. Search results are presented for gravitational waves produced b…
AGILE, Fermi, Swift, and GASP-WEBT multi-wavelength observations of the high-redshift blazar 4C 71.07 in outburst
S. Vercellone, P. Romano, G. Piano +56
The flat-spectrum radio quasar 4C 71.07 is a high-redshift (), -loud blazar whose optical emission is dominated by the thermal radiation from accretion disc. 4C …
An Optically Targeted Search for Gravitational Waves emitted by Core-Collapse Supernovae during the First and Second Observing Runs of Advanced LIGO and Advanced Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1195
We present the results from a search for gravitational-wave transients associated with core-collapse supernovae observed within a source distance of approximately 20 Mpc during the…
