Follow-Up Analysis and Visualization of Multimessenger Data for Baikal-GVD

Modern astronomy aims to study the astrophysical objects with the various types of signals incoming from them. To achieve the goals of the multi-messenger astronomy, experiments should exchange data, that can be done with the alert messages. Alert contains essential information about the detected event. These messages are distributed via international networks facilitating the rapid follow-up of transient astrophysical phenomena. The Baikal-GVD alert system receives external alerts and applies different methods to search for signal coincidences. For better understanding of the alert system workflow and researching of the astrophysical neutrino sources the alert visualization is necessary. This work deals with the techniques that are used within the coincidence search process and the visualization of the alerts: Baikal-GVD alerts and external messages from experiments like the IceCube neutrino telescope, Fermi gamma-ray telescope and LIGO/Virgo/KAGRA gravitational observatories.
