Titolo: Bright late-type stars in the thin Disk of the Milky Way   Abstract: Red supergiants (RSGs) and asymptotic giant branch (AGB) stars are the brightest sources at infrared wavelengths, detectable at a distance of a few  megaparsecs —- even in heavily obscured galactic centers. Through winds and mass loss, they enrich and sculpt the interstellar medium. Despite similar spectral energy distributions

 

Titolo: Association of the astrophysical neutrinos with flares from relativistic jets launched by supermassive black holes?   Abstract: Over the past decade, the IceCube Neutrino Observatory has detected a few hundreds of high-energy (HE) neutrinos from cosmic sources. Despite numerous studies searching for their origin, it is still not known which source populations emit them. A few confident individual associations exist
