Description
We present preliminary results of a photometric investigation on IC10 using data collected with ACS@HSTS and WFPC2@HST. We estimate the distance using the Tip of the Red Giant Branch (TRGB). According to current estimates, IC10 seems to be a member of the M31 group. By assuming the same distance for the two different pointings, the reddening shows a significant decrease when moving from the center toward the external regions. Moreover, we show that stellar isochrones at fixed metal content, distance and reddening account for both Main Sequence (MS) and evolved stellar components.

    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
