In recent years, the IceCube realtime program has been publishing alerts following the detection of neutrinos with moderate-to-high probability of being astrophysical. Such alerts are distributed through the NASA General Coordinates Network in two steps: a prompt notice with preliminary details, followed by a circular containing detailed reconstruction information. In this contribution, I will...
KM3NeT is a Cherenkov-based neutrino telescope under construction in the depth of the Mediterranean sea. It will consist of two main detectors, ARCA and ORCA, sensitive to energies from MeV to PeV. Presently a fraction of both detectors is already data-taking with a completion date foreseen for 2028.
The telescope design allows for a high duty-cycle, a large field of view, and an...
Since the release of the Gravitational Wave Transient Catalog GWTC-2.1 by the LIGO-Virgo collaboration, sub-threshold gravitational wave (GW) candidates are publicly available. They are expected to be released in real-time as well, in the upcoming O4 run. Using these GW candidates for multi-messenger studies complements the ongoing efforts to identify neutrino counterparts to GW events. This...
In the realm of multi-messenger astronomy (MMA), Implementing an optimal observing strategy to follow electromagnetic (EM) counterparts across the network observatories is a crucial factor to achieve successful observations. By employing the Multi Order Coverage (MOC) data structure and ranking methods, we present an observing strategy in the context of the GECKOrchester tool. The performance...
The diversity in the observed properties of different types of supernovae (SNe) are crucial to understanding how the life of stars ends differently. Diversity among underlying powering mechanisms may play a vital role among other possible factors (e.g., progenitor, environment). Unique properties and scarcity of Gamma-ray bursts (GRBs) associated SNe (GRB-SNe) seek attention and are exciting...
Iranian National Observatory Project is a medium size optical telescope with a primary diameter of 3.4m dedicated for observations of galactic/extra galactic and transient sources. The telescope is an optical RC telescope benefitting from on axis Cassegrain focus and side Cassegrain stations. We aim to detect GRB afterglows and optical prompts/ Kilonoveas and the optical counterparts of GW...
