Descripción
Out of the ˜ 70 extragalactic sources known to emit in the Very High Energy band (VHE, E > 100GeV), only 5-6 are known to be Flat Spectrum Radio Quasars (FSRQs), and they are all found at intermediate or high redshifts. In this paper, we explore the conditions that trigger sub-TeV emission on this particular type of sources and we concentrate on the two most distant examples of this special population of blazars: the gravitationally lensed quasar B0218+357 and PKS 1441+25.

    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

    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
