[Todos] Ciclo de coloquios IAR: Lunes 23 de mayo, 11 hs

[Florencia Laura Vieyro]

Colegas,

Los invitamos a participar del Ciclo de Coloquios del IAR el próximo lunes
23 de mayo a las 11 hs. En esta ocasión el Sr. Noel Castro-Segura, de la
Universidad de Southampton, nos hablará sobre la binaria de rayos X de baja
masa Swift J1858.

¡Los esperamos!

Saludos cordiales,

Florencia

Title: The Outflow Accretion Legacy Surveys (OLAS): simultaneous
panchromatic observations of the low mass X-ray binary Swift J1858

Abstract:
I will present the results of a unique multi-wavelength campaigns focused
on the recently discovered LMXB Swift J1858. This system displayed extreme
variability in both X-ray and optical bands, similar to the famous black
hole binary V404 Cyg during its 2015 outburst. Our observations covered the
full frequency range from X-ray to radio and were provided by observatories
including XMM-Newton, NuSTAR, NICER, VLTs, Gemini, GTC, VLA, MeerKAT and
HST. A key feature of the campaign is a 4-hour window during which we
obtained time-resolved, strictly simultaneous observations across the whole
electromagnetic spectrum.
I will walk you through the findings obtained by monitoring programs of
independent instruments, then we will step back into a multi-wavelength
perspective to get insights in the geometry of the system and the physical
mechanism driving its outflows, unveiled thanks to the unprecedented
coordination of several major observatories across the globe. We will
finish with an overview of the findings of the system and how coordinated
multi- wavelength campaigns can help us to understand the physics of
compact objects and how they interact with their environment.
