    The Multi-Messenger Astrophysics (MMA) era has necessitated that we coordinate the community at an entirely new level. Many of these events (e.g., gravitational wave and neutrino sources) are not localized enough to unambiguously identify the electromagnetic counterpart. Instead, large-scale searches are necessary to localize the source to combine the information from the different...

    Alerts and results from Swift-BAT GUANO data and the NITRATES analysis

    In 2019 the Gamma-ray Urgent Archiver for Novel Opportunities (GUANO) was implemented, allowing for time-tagged event data for the Swift Burst Alert Telescope (BAT) to be saved on command around times of interest. This allows for more sensitive analyses to be performed on the ground. The most sensitive being, the...

    The Large Area Telescope (LAT), on board the NASA Fermi Gamma-ray Space Telescope, has various properties that make it a great instrument for time-domain astronomy. These include its large field of view (> 2 steradians), its all-sky-survey mode of taking observations and its large energy range (100 MeV - >1 TeV). In this talk, I will discuss the various tools and platforms that Fermi-LAT...

    Multimessenger astrophysics recently provided groundbreaking results, in many cases involving transient sources. The study of this type of objects can be challenging, especially from an observational point of view. In particular, in the electromagnetic domain, the very-high-energy gamma-ray band (E>~100 GeV) can provide vital information on the sources themselves and their environment. In this...

    TESS Transient Light Curve Patrol
    The Transiting Exoplanet Survey Satellite (TESS) is a space telescope mission developed by NASA with the goal of detecting exoplanets. Over the duration of it's mission, TESS has trained its wide-field imaging array on dozens of sky sectors, and identified thousands of candidate targets. Our team has developed a a subtraction pipeline for these full frame...

    Data products, public access, and survey optimization for the Argus Array

    The Argus Array will be a 900-telescope optical survey instrument with a combined collecting area equivalent to a 5-meter telescope and an 8000 sq. deg simultaneous field of view, currently slated for first light in 2027. Operating at depths comparable to those of the deepest active sky surveys, Argus will capture a...

    Multi-Messenger Online Data Analysis platform (MMODA) and Galaxy platforms provide services for on-the-fly analysis of publicly available data astronomical and astroparticle data for a range of telescopes. The platforms also provide a possibility for users to add new services based on user-contributed analysis workflows formulated in the form of python notebooks.

    We have developed an automatic pipeline to predict the topics of a follow-up ATel and to assign data-analysis workflows, that will be publicly available at https://www.astro.unige.ch/mmoda/. To achieve this, we have created an ontology of telescopes, observatories and instruments in order to detect them in Astronimical Telegrams. Studying the occurances of these telescopes in the ATels, we...

    Discovered in 2007, fast radio bursts (FRBs) are luminous, millisecond duration radio bursts that have quickly become one of the most fascinating classes of radio transients. The progenitor of FRBs remains a mystery, however, through observations like that of the FRB-like bursts detected from a galactic magnetar, SGR 1935+2154, it has been shown that collaborative efforts from multiple...

    Pulsar Timing Array (PTA) is close to detecting Gravitational Wave Background (GWB) in the frequency range of nHz to µHZ. We present an extended analytic model to describe the characteristic spectrum of the GWB using the merger rate of supermassive black hole binary (SMBHB) in the Universe. Astrophysical observables (Galaxy stellar mass function (GSMF), pair fraction, merger timescale and mass...

    The coincident detection of Gravitational Wave (GW~170817) and short Gamma Ray Burst (GRB~170817A) confirmed their common origin from the coalescence of binary neutron stars (BNS). Depending on the BNS masses and equations of state, the outcome could be a black hole or a millisecond magnetar. In the presence of a magnetar, a significant portion of its rotational energy is transferred to the...

    The detection of SN burst neutrinos from a nearby/Galactic core-collapse supernova (SN) can provide an early warning to the multi-messenger astronomy community. As the world’s largest water-Cherenkov detector, Super-Kamiokande (SK) maintains an independent SN alert system, “SNWatch”, and also contributes to SNEWS. Recent upgrades to the SK detector and SNWatch have increased the capabilities...

    The Supernova Early Warning System (SNEWS) is a network of neutrino and dark matter detectors which aims to detect coincident neutrino signals in multiple detectors and alert the worldwide observer community. It has been in automated operation since 2005, but is now undergoing a significant upgrade with goals including increasing sensitivity for both neutrino bursts as well as pre-supernova...

    The Gravitational Wave Treasure Map is designed to help coordinate electromagnetic followup of gravitational-wave (GW) events. It allows observers to easily report their planned and executed observations in search of counterparts to GW events, and to query the reports of other observers, in a programatic way. The goal is to enable coordination between observatories in order to minimize...
