Description
In this paper, we study the circumgalactic environment of LINER host galaxies, in a sample of 166 objects drawn from a Multifrequency Catalogue of LINERs by Carrillo et.1999). The aim of our work is to compare the environment of different types of LINERs, therefore we subdivided our sample in three groups: LINERs type, type, and transition objects (TL). The search has been carried out on the Digitized Sky Survey (DSS) up to a projected linear distance of 300using methods applied in several previous studies. We found that type LINERs and TLs seem to possess a richer environment than those of type. In addition, type LINERs and TLs show large companions with frequency similar to that of bright IRAS galaxies and Seyfert 2 host galaxies. We suggest that an evolutionary sequence from starbursting systems, to type and eventually to type-1 AGN, may be appropriate for most AGN and may be independent of luminosity.

    MUSE view of PDS 456: Kiloparsec-scale wind, extended ionized gas, and close environment
    PDS 456 is the most luminous (L bol ∼ 10 47 erg s −1) radio-quiet quasar at z < 0.3 and can be regarded as a local counterpart of the powerful quasars shining at Cosmic Noon. It hosts a strong nuclear X-ray ultra-fast (∼0.3c) outflow, and a massive and clumpy CO (3-2) molecular outflow extending up to ∼5 kpc from the nucleus. We analyzed the first

    TOI-837 b is a young Saturn-sized exoplanet with a massive 70 M<SUB>⊕</SUB> core
    We present an exhaustive photometric and spectroscopic analysis of TOI-837, a F9/G0 35 Myr young star, hosting a transiting exoplanet, TOI-837 b, with an orbital period of ~8.32 d. Utilizing data from the Transiting Exoplanet Survey Satellite and ground-based observations, we determine a planetary radius of $0.818_{-0.024}^{+0.034}$ R J for TOI-837

    Changing Look of the Optical Spectrum of the MeV Blazar PKS 0446+112 (4FGL J0449.1+1121)
    Following the high activity of the γ-ray Fermi source 4FGL J0449.1+1121 (PKS 0446+112), possibly associated with a IceCube neutrino event IC-240105A, we obtained optical spectroscopy with the Gran Telescopio Canarias of the counterpart. We detect a clear emission line at 3830 Å identified as Lyα that confirms the redshift of source at z = 2.153
