La time domain astronomy: verso la prima luce di Rubin LSST e di SOXS (chair: M.G. Lattanzi)
"Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) sara’ rivoluzionario per diversi aspetti: la cadenza temporale, la porzione di cielo osservata, la quantita’ di dati che mettera’ a disposizione in diversi filtri (ugrizy) per i prossimi dieci anni a partire da quest’anno.
Ogni notte 10 milioni di eventi “time domain” saranno resi disponibili alla comunita’ tramite i broker...
SOXS (Son Of X-Shooter) is the new ESO instrument of the 3.58-m New Technology Telescope at the La Silla Observatory. It is a single-object spectrograph offering a wide simultaneous spectral coverage from U- to H-band (350-2000 nm). The instrument is going to become one of the main follow-up instruments in the Southern hemisphere for the classification and characterization of transients, e.g....
The presence of blue-shifted iron K absorption features in the spectra of nearby AGN was revealed over 2 decades ago with the first XMM-Newton observations of nearby AGN. They indicate the presence of powerful ultra-fast outflows launched from the innermost regions of the accretion disk with velocities up to 0.3c.
After the successful launch of the XRISM observatory, we now are entering a new...
Massive stars at the end of their life typically experience the gravitational collapse of their iron core, leading to supernova explosions. These events not only generate compact stellar remnants, but also regulate the dynamics of their host galaxies and their chemical composition by producing new elements. In the most extreme cases where fast rotation and strong magnetic fields are both...
