Large aperture ultra-precision mirrors are critical components in next-generation astronomical telescopes such as the China Space Station Telescope（CSST） and the MUltiplexed Survey Telescope（MUST）. However, traditional 5/6-axis CNC "Box machines" combined with sub-aperture polishing techniques (CCOS, MRF, IBF) face challenges in cost-effectiveness

Measurements of the 511 keV emission reveal the presence of a steady injection of positrons that is very concentrated around the Galactic centre, and whose origin remains unknown. While astrophysical sources do not easily fit the observed morphology and intensity of this excess, MeV dark matter has been proposed as a compelling explanation with

El Spanish Space Solar Physics Consortium (S3CP) es un grupo formado por cinco instituciones españolas, entre ellas el Instituto de Astrofísica de Canarias (IAC), que desde 2002 trabajan conjuntamente para profundizar en el conocimiento de la física solar. En el marco de este consorcio se han desarrollado tres espectropolarímetros solares que han

Matter ejection, in the form of either winds or jets, is ubiquitous in accreting X-ray binaries. Although it is clear that accretion and ejection are profoundly intertwined in these types of systems, the origin and the details of such an interconnection are yet to be unraveled. This is particularly true for systems where a low-magnetized neutron
