Description
(596) Scheila is a large primitive asteroid observed with a comet-like apearence last December. We present near-infrared spectra (0.8-2.4 μm) obtained at different rotational phases, covering a whole rotation period of the object after the ejection event, a spectrum in the 2.2-4.0 μm region obtained in 2007, and mid-infrared photometry measured by WISE in Feb. 2010. We show that the surface is homogeneous, and corresponds to a dark (diameterD=113.3km, albedo at 3.4μm p3.4=0.068) primitive D-type asteroid. We also find that the best meteorite analogs are carbonaceous chondrites, in particular those of the CM sub-group.

    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
