Descripción
After an outburst that lasted more than 2.3 years (starting around June 12th., 2007; Palmer et al., ATel #1113), the neutron star transient and atoll source 4U 1608-52 has returned to quiescence. The source was last detected by Swift-BAT, RXTE-PCA and RXTE-ASM on September 14th. (~0.006 BAT c/s/cm2), September 19th. (~3.5 mCrab) and October 5th. (~1.4 ASM c/s), 2009, respectively. We obtained daily Swift-XRT observations since October 20th.

    Performance of the image persistence model for Euclid infrared detectors
    Large-format infrared detectors are at the heart of major ground and space-based astronomical instruments, and the HgCdTe HxRG is the most widely used. The Near Infrared Spectrometer and Photometer (NISP) of the ESA's Euclid mission launched in July 2023 hosts 16 H2RG detectors in the focal plane. Their performance relies heavily on the effect of
