[Todos] Ciclo de coloquios del IAR: Lunes 22 de abril 14hs.

[Sector Científico IAR]

Colegas,

los invitamos a participar del Ciclo de Coloquios del IAR el próximo lunes
22 de abril  a las 14:00hs. En esta ocasión, el Dr. Eduardo Gutierrez nos
contará sobre sus trabajos como becario posdoctoral en el Institute for
Gravitation and the Cosmos en Penn State University.

Debajo podrán ver la información sobre la charla que nos brindará.

La charla se llevará a cabo en modo presencial y también será transmitida
por el canal de YouTube del IAR:

Coloquio a cargo del Dr. Eduardo Gutierrez

*Título:* Multimessenger Radiation from Binary Neutron Star Mergers

*Resumen: * Neutron star (NS) mergers are among the most promising
multimessenger sources in the Universe, as demonstrated by the coincident
detection of gravitational waves (GWs) and multiwavelength electromagnetic
(EM) radiation with the GW170817 event. Moreover, they have also been
proposed as potential sources of ultra-high-energy cosmic rays and
high-energy neutrinos. One of the most studied observable phenomena
associated with NS mergers are the so-called short-duration gamma-ray
bursts (sGRBs), which are thought to originate from a relativistic jet
launched by the merger remnant. However, there are still uncertainties
about the exact nature of such a remnant: it may be a promptly formed black
hole (BH), a hypermassive NS that collapses to a BH on timescales of ~100
ms, or even a stable NS. In this talk, I will talk about the theoretical
modeling of NS mergers through GRMHD simulations, what these studies teach
us about the properties of matter at extreme densities, and how we can
predict potential multimessenger signatures from these phenomena.
