Descripción
The extension of the highly successful Doppler technique into the near-infrared (0.9-2.5 μm) is opening new parameter domains for extra-solar planet searches in terms of ages and masses of the primary stars. Here we present the current status of NAHUAL, a next generation near-infrared spectrograph for the 10.4-meter Gran Telescopio Canarias (GTC). Among its observing modes, it includes a hyper-stable high-resolution capability aimed at high-precision Doppler measurements of cool stars in the near-infrared. The sticky question of the best wavelength calibration for the near-infared is addressed in the last section of this paper.

    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

    Galaxy archaeology - The quest for ancient mergers
    The hierarchical assembly of galaxies through mergers is a key channel of galaxy evolution in the ΛCDM cosmological model. Quantifying these ancient transformative accretion events from observations of present day galaxies is a crucial goal of extragalactic archeology. Achieving this goal is challenging as the dominant epoch of galaxy assembly lies

    RAD@home Citizen Scientists Uncover Emerging Jet-Galaxy Interactions
    The RAD12 object's recent investigation (Hota et al. 2022), via the RAD@home Astronomy Collaboratory, has provided a streamlined and focused perspective on the complex subject of jet-galaxy interactions, which has always posed a significant challenge for observational confirmation. This emerging field holds increasing significance, providing a
