WebThe reported results confirm and strengthen the very fast transient nature of these sources, given that all their newly detected outbursts have a duration less than ∼ similar-to \sim ∼ 3 hours. Additionally, they provide the first evidence for a possible recurrent fast transient behaviour as all three sources were detected in outburst by ISGRI more than once … Web18 de abr. de 2024 · Short rise times of Fast Blue Optical Transients (FBOTs) require very light ejected envelopes, $M_{ej} \leq 10^{-1} M_\odot$, much smaller than of a typical …

Empty circles mark the upper limits on the X-ray luminosities of the very rapidly declining type Ic supernova 2005ek, the rapidly rising iPTF16asu, which later showed a Ic-BL spectrum, and the fast-rising, luminous transient "Dougie."
WebA population of particular recent interest is “fast-evolving luminous transients” (Rest et al. 2024) or “fast blue optical transients” (Margutti et al. 2024). A consistent definition of this “class” does not yet exist; these terms typically refer to transients with rise times and peak luminosities too fast and too
