🌌 ¿Qué ocurre cuando una supernova choca contra un "muro" invisible en el espacio? La misión IXPE de la NASA ha desvelado los secretos del remanente RCW 86, los restos de la primera explosión estelar registrada por la humanidad en el año 185 d.C. Descubre el fascinante efecto de choque reflejado y las imágenes en rayos X más reveladoras de esta colisión cósmica.

La più lunga osservazione mai effettuata da IXPE risolve il mistero dei getti virali dei buchi neri
Un team internazionale di astronomi che utilizza IXPE (Imaging X-ray Polarimetry Explorer) della NASA ha identificato l’origine dei raggi X nel getto di un buco nero supermassiccio, rispondendo a una domanda rimasta irrisolta fin dagli albori dell’astronomia a raggi X.

Which is better for underlayment: IXPE vs EVA?
The acoustic underlayment – plays an equally crucial role in comfort, noise reduction, and flooring longevity.
What distinguishes of IXPE and EVA? Let’s explore:

Blazars, supermassive black hole systems (SMBHs) with highly relativistic jets aligned with the line of sight, are the most powerful long-lived emitters of electromagnetic emission in the Universe. We report here on a radio to gamma-ray multiwavelength campaign on the blazar BL Lacertae with unprecedented polarimetric coverage from radio to X-ray wavelengths. The observations caught an extraordinary event on 2023 November 10-18, when the degree of linear polarization of optical synchrotron radiation reached a record value of 47.5%. In stark contrast, the Imaging X-ray Polarimetry Explorer (IXPE) found that the X-ray (Compton scattering or hadron-induced) emission was polarized at less than 7.4% (3sigma confidence level). We argue here that this observational result rules out a hadronic origin of the high energy emission, and strongly favors a leptonic (Compton scattering) origin, thereby breaking the degeneracy between hadronic and leptonic emission models for BL Lacertae and demonstrating the power of multiwavelength polarimetry to address this question. Furthermore, the multiwavelength flux and polarization variability, featuring an extremely prominent rise and decay of the optical polarization degree, is interpreted for the first time by the relaxation of a magnetic "spring" embedded in the newly injected plasma. This suggests that the plasma jet can maintain a predominant toroidal magnetic field component parsecs away from the central engine.
