Abstract: Active galactic nuclei (AGNs) are extreme astrophysical environment that result in copious emission of X-rays. I describe how large archival datasets from X-ray telescopes can be used to search for new physics using the X-ray spectrum of AGNs.
From Infinitely Large to Infinitely Small
Gr@v member António P. Morais gave a talk at Escola Secundária José Régio in Vila do Conde with title "Do Infinitamente Grande ao Infinitamente Pequeno - uma jornada pelas interações fundamentais na natureza". António was an invited speaker to participate in a sequence of seminars entitled "A Biblioteca convida...", and presented to 11th and 12th grade Science and Technology students the four fundamental interactions in nature and how have they shaped our Universe.
