In this work, we report the detection and characterization of two new eccentric WJs, TOI-2147 b and TOI-6019 b, initially identified as planet candidates by the Transiting Exoplanet Survey Satellite (TESS). We combined TESS photometry with ground-based follow-up observations, including multiband photometry from LCOGT and MuSCAT2, high-angular-resolution speckle imaging, and high-precision radial velocity measurements from the high-resolution Manfred Hirt Planet Finder Spectrograph (MaHPS). Using these data, we were able to confirm the planetary nature of both candidates. TOI-2147 b has a radius of 10.5+/-0.3R_{Earth}_ and a mass of 116+/-22M_{Earth}_. It orbits its slightly metal-poor ([Fe/H]=-0.29_-0.08_^+0.07^) G-type host star on an eccentric orbit (e=0.29+/-0.07) with a period of 26.2 days. TOI-6019 b has a radius of 12.3+/-0.3R_{Earth}_ and a mass of 149+/-15M_{Earth}_. It orbits a slightly evolved, solar-metallicity G-type sub-giant with a period of 14.5 days on a significantly eccentric orbit (e=0.48_-0.04_^+0.05^). Both planets have bulk densities below that of Jupiter, indicating mildly inflated radii, with interior structure modeling using GASTLI. This suggests that tidal heating from the nonzero eccentricities likely contributes to this inflation and disfavors large atmospheric metal enrichment. No significant signals from additional companions were detected in the radial velocity time series or transit timing variations. Together with the elevated eccentricities, this is consistent with a high-eccentricity migration origin for both systems.2026A&A...712A.157Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/712/A157CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/712/A157https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/712/A157http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/712/A157https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/712/A157https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/712/A157http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/712/A157GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/712/A157/table5Radial velocities of TOI-2147recnoRecord number assigned by the VizieR team.
