¡Un nuevo miércoles de Coloquio en el IFIS PUCV! Este 2 de octubre desde las 10:00 AM en la sala 208, Marilyn Cruces, académica de la Pontificia Universidad Católica de Chile, presentará “The transient radio sky”.
Te dejamos el abstract de la presentación:
The sky, when observed at radio frequencies, is largely populated by transient events with timescales as short as a fraction of a millisecond. A clear example is the detection of Fast Radio Bursts (FRBs), an observational phenomenon characterized by bright flashes of extragalactic origin. The progenitors of FRBs remain mysterious, posing one of the main open questions in modern astronomy. However, their short durations—sometimes as brief as microseconds—and high energies, up to 10e42 erg, imply that the emission must be coherent and originate from a very compact region, no more than a few kilometers in size. This is why the most popular scenarios associate FRBs with neutron star populations, such as pulsars and magnetars.
In this presentation, we will discuss the observational evidence helping us understand the origin of FRBs, as well as the main challenges and biases in their detection with current and next-generation radio facilities.
