cds-question@unistra.frradio-galaxiesradio-continuum-emissionFrom the LOFAR Two-metre Sky Survey second data release (LoTSS DR2) at 144 MHz, we identified a peculiar radio galaxy, J0011+3217. It has a large, one-sided diffuse secondary wing that stretches up to 0.85Mpc (roughly 85% of the size of the primary lobe). The linear size of the primary lobe of the galaxy is 0.99Mpc. This peculiar source is a giant radio galaxy with a misaligned primary lobe. There is an optical galaxy 16kpc (7arcsec) from the host active galactic nucleus of J0011+3217. J0011+3217 has a radio luminosity of 1.65x10^26^W/Hz at 144MHz with a spectral index of -0.80 between 144 and 607MHz. J0011+3217 is located 1.2Mpc from the centre of the Abell 7 cluster. The Abell 7 cluster has a redshift of 0.104 and a mass (M500) of 3.71x10^14^M_{sun}_. The cluster is associated with strong X-ray emission. We studied the X-ray emission around the cluster and from the region surrounding J0011+3217 using an XMM-Newton image of J0011+3217, and we analysed the velocity structure and spatial distribution of galaxies in the cluster, showing that J0011+3217 inhabits an offset group of galaxies that are moving with respect to Abell 7. The off-axis distortion, or bending, of the primary lobe of J0011+3217 in the outer edges has a strong effect on the relative motion of the surrounding medium; this in turn causes the bending of the jets in the opposite direction of the cluster (like wide-angle tailed sources). We suggest that the morphology of J0011+3217 is influenced by ram pressure created by the Abell 7 cluster, highlighting the complex interactions between the source and the surrounding cluster environment.2024A&A...689A.301Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/689/A301CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/689/A301https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/689/A301http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/689/A301https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/689/A301https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/689/A301http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/689/A301GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/689/A301/list (List of fits images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/689/A301/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/689/A301/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/689/A301/list?GETtext/xml+votable180.050000true3.5800532.283930.0055555555555555566/20335 20339 20342 20346https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/689/A301?format=asciiRadiodefaultJ/A+A/689/A301/listList of fits imagesNxNumber of pixels along X-axismeta.numberintNyNumber of pixels along Y-axismeta.numberintObs.dateObservation datestime.epoch;obsnullablesizeSize of FITS fileKibytephys.size;meta.fitsintFileNameName of FITS file, in subdirectory fitsmeta.id;meta.fitscharTitleTitle of the FITS filemeta.title;meta.fitscharDEJ2000Declination of center (J2000)degpos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
