AGILE Observations of Two Repeating Fast Radio Bursts with Small Intrinsic Dispersion Measures

C. Casentini, F. Verrecchia, M. Tavani +30

We focus on two repeating fast radio bursts (FRBs) recently detected by the CHIME/FRB experiment in 2018--2019 (Source 1: 180916.J0158+65, and Source 2: 181030.J1054+73). These sou…

Discovery of a 2.8 s pulsar in a 2 d orbit High-Mass X-ray Binary powering the Ultraluminous X-ray source ULX-7 in M51

G. A. Rodríguez Castillo, G. L. Israel, A. Belfiore +26

We discovered 2.8 s pulsations in the X-ray emission of the ultraluminous X-ray source (ULX) M51 ULX-7 within the UNSEeN project, which was designed to hunt for new pulsating ULXs…
