Description
The authors report the results of high resolution and high S/N observations of diffuse interstellar bands (DIBs) towards SN 1987A in the LMC. For the first time they clearly detect the LMC component of the 5780, 5797 and 6284 Å DIBs, and possibly that of 5778 and 6269 Å. Moreover, they observe the Galactic components of the 5778, 5780, 5797, 6283, 6376 and 6379 Å bands, along a line of sight with very low reddening [E(B-V) ≅ 0.07]. The LMC components are generally weaker than the Galactic ones, while the opposite is observed for ISNa I and K I. The band strengths are compared with the total color excess towards the supernova.

    Calibrating the Clock of JWST
    JWST, despite not being designed to observe astrophysical phenomena that vary on rapid timescales, can be an unparalleled tool for such studies. If timing systematics can be controlled, JWST will be able to open up the subsecond infrared timescale regime. Rapid time-domain studies, such as lag measurements in accreting compact objects and solar

    Comparing metallicity correlations in nearby non-AGN and AGN-host galaxies
    The gas-phase metallicity distribution within galaxies records critical information about galactic evolution. In this work, we investigate how active galactic nuclei (AGNs) influence this distribution by measuring the two-point correlation functions of gas-phase metallicity in 95 non-AGN and 37 AGN-host galaxies from the Calar Alto Legacy Integral

    Multiband Optical Variability of the Blazar 3C 454.3 on Diverse Timescales
    Due to its peculiar and highly variable nature, the blazar 3C 454.3 has been extensively monitored by the WEBT team. Here, we present for the first time these long-term optical flux and color variability results using data acquired in B, V, R, and I bands over a time span of about two decades. We include data from WEBT collaborators and public
