Biography

I obtained my PhD in Astronomy and Astrophysics at the University of Turin (Italy), in the topic of galactic environments of blazars, and during this period I spent several months working at the Harvard-Smithsonian Center for Astrophysics (CFA, Cambridge, USA). After I graduated, I was a postdoctoral researcher at the University of Zagreb (Croatia), where I joined the COSMOS collaboration.
I started working at ESA in 2018 with a Research Fellowship using the X-ray space mission XMM-Newton. Now my current role is Support Archive Scientist for ESASky.

ESASky: a visualisation tool for multi-messenger astronomy
Nuria Alvarez Crespo

Six years after the discovery of the first gravitational wave (GW) event, today astronomers observe merging black holes and neutron stars routinely, and this topic will become key to understand astrophysical phenomena during the next decade. One of the current challenges of multi-messenger astronomy is to link the events with their electromagnetic counterparts, since GW localisation usually involves a big sky area, from tens up to hundreds of square degrees. Archival data and catalogs are fundamental instruments to understand this rapidly evolving field, since their study helps to narrow-down the sky regions to be observed, discard already known transient sources and re-analyse data to look for missed multi-messenger events similar to the already detected ones.
ESASky is a science-driven discovery portal than allows scientists to explore interactively a large collection of astronomical data, providing a very useful tool to explore the multiwavelength sky with the click of a button. ESASky now shows the GW probability map on the sky, allowing users to look for electromagnetic counterparts for the GW events and using ESASky to quickly access all available archival electromagnetic data. In the future, we will also include the IceCube neutrino footprint.
