The peculiar case of the active galactic nucleus in PBC J2333.9-2343 – 17 Settembre 2018, ore 11:00 Aula Gratton

Euniversity of VALPARAISO – CHILE Lorena Hernandez Abstract Under unification schemes, active galactic nuclei (AGN) can be explained by orientation effects. However, some sources show properties at different frequencies that led to incongruent classifications and cannot be explained by such unification scheme. This is the case of PBC J2333.9-2343; its optical pectrum is of a […]

Detection of the Missing Baryons in the Warm-Hot Intergalactic Medium – 19 Settembre 2018, ore 11:00 Aula IB09

INAF – Ossrvatorio Astronomico di Roma Fabrizio Nicastro It has been known for decades that the observed number of baryons in the local Universe falls about 30-40% short of the total number of baryons predicted by Big-Bang Nucleosynthesis, inferred by density fluctuations of the Cosmic Microwave Background and seen during the first 2-3 billion years […]
