A mysterious feature in the NICER spectrum of 4U 1820-30: A gravitationally redshifted absorption line?
R. Iaria, T. Di Salvo, A. Anitra +6
A mysterious absorption feature at approximately 3.8 keV has been identified in the NICER spectrum of the low-mass X-ray binary system 4U 1820-30. We interpret this feature as a gr…

High energy time lags of Gamma Ray Bursts
C. Maraventano, G. Ghirlanda, L. Nava +5
Positive lags between the arrival time of different photon energies are commonly observed in Gamma-Ray Bursts (GRBs), where soft photons lag behind harder ones. However, some GRBs…
