Descripción
We present in this contribution a review of recent results of parameters of massive OB stars in the Milky Way, the Magellanic Clouds and nearby spirals. The review is timely because of the strong lowering of the temperature scale of Galactic OB stars produced by the new model atmospheres, including sphericity, blanketing and mass-loss, that are also discussed, and because of the boost suffered by extragalactic stellar physics in the last years. The effects on the determination of mass-loss and the Modified Wind Momentum-Luminosity Relationship are discussed, and a comparison with evolutionary models is provided. We finally present a comparison of abundances from OB stars and H II regions in Orion and M 33.

    Application of Bayesian Inference to disentangle CMB foregrounds
    Both Galactic dust emission and Cosmic infrared background anisotropies (CIB) act as a dominant foreground contaminant for the measurements of the CMB anisotropies (intensity and polarization) at the frequency range above 217 GHz. The Galactic dust and CIB share a similar form of spectral energy distribution, which makes it harder to disentangle

    Constraining stellar and orbital co-evolution through ensemble seismology of solar-like oscillators in binary systems
    The evolution of stars and their hosting binary systems is a highly interactive process and cannot be investigated in a segregated manner. Due to the constraints drawn by stellar binarity, oscillating red-giant stars in binary systems represent a unique opportunity to study the details of the structure and evolution of stars in the advanced phases

    Triple-Double Radio Galaxies: Clues for understanding recurrent AGN activity
    Using LOFAR Two-metre Sky Survey (LoTSS), we discovered three cycles of episodic jet activity (J1225+4011, Chavan et al. 2023, MNRAS) in a giant radio galaxy, which is an extremely rare class of restarted Active Galactic Nuclei (AGN), making it only fourth of its kind. It is also called 'Triple-Double Radio Galaxy' (TDRG). J1225+4011 extends up to
