Revealing the state transition of Cen X-3 at high spectral resolution with Chandra

Kavli Affiliate: Norbert Schulz | First 5 Authors: Graciela Sanjurjo-Ferrín, Jose Miguel Torrejón, Lida Oskinova, Konstantin Postnov, Jose Joaquín Rodes-Roca | Summary: Cen X-3 is a compact, high-mass X-ray binary (HMXRB), likely powered by Roche lobe overflow. We present a phase-resolved X-ray spectral and timing analysis of a target of opportunity textit{Chandra} observation made during […]

First Resolution of Microlensed Images of a Binary-Lens Event

Kavli Affiliate: Jinyi Shangguan | First 5 Authors: Zexuan Wu, Subo Dong, A. Mérand, Christopher S. Kochanek, Przemek Mróz | Summary: We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI). The light curves show weak binary perturbations, complicating the analysis, but the […]
