cds-question@unistra.fractive-galactic-nucleiradio-galaxiesvery-long-baseline-interferometrySupermassive black holes (SMBH) are essential for the production of jets in radio-loud active galactic nuclei (AGN). Theoretical models based on Blandford & Znajek (1977MNRAS.179..433B) extract the rotational energy from a Kerr black hole, which could be the case for NGC1052, to launch these jets. This requires magnetic fields on the order of 1000G to 10000G. We imaged the vicinity of the SMBH of the AGN NGC1052 with the Global Millimetre VLBI Array and found a bright and compact central feature that is smaller than 1.9 light days (100 Schwarzschild radii) in radius. Interpreting this as a blend of the unresolved jet bases, we derive the magnetic field at 1 Schwarzschild radius to lie between 200G and ~83000G consistent with Blandford & Znajek (1977MNRAS.179..433B) models.2016A&A...593A..47Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/593/A47CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/593/A47https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/593/A47http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/593/A47https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/593/A47https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/593/A47http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/593/A47GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/593/A47/list (List of FITS images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/593/A47/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/593/A47/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/593/A47/list?GETtext/xml+votable180.050000true40.2699937-8.25576420.0055555555555555566/36785https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/593/A47?format=asciiRadiodefaultJ/A+A/593/A47/listList of FITS imagesrecnoRecord number assigned by the VizieR team.
