  "abstract": "We present new Chandra observations of seven broad-line AGNs in low-mass galaxies ($M_\\star < 5 \\times 10^9\\,M_\\odot$) selected from the GAMA sample of Salehirad et al. (2022). X-ray emission is detected in six galaxies, with luminosities spanning $\\log(L_{\\rm 0.5-8\\,keV}/{\\rm erg\\,s^{-1}})\\approx40.5$--43.8. Their X-ray luminosities generally exceed predictions for X-ray binary populations, and their proximity to the optical galaxy nuclei favors accreting massive black holes as the dominant emission source. Spectral fits for four sources yield photon indices $Γ\\approx1.7$--2.2, with little evidence for intrinsic absorption in most cases. Virial black hole masses and hard X-ray bolometric corrections imply nominal Eddington ratios $λ_{\\rm Edd}\\approx0.004$--1.1, although uncertainties are substantial. Optical tracers generally imply higher bolometric luminosities and Eddington ratios, particularly for the X-ray-undetected galaxy. The X-ray-bright sources are broadly consistent with optical AGN scaling relations involving H$α$ and [O III], whereas most lie below the established X-ray--mid-infrared relation, potentially reflecting host-galaxy contamination. Four sources are consistent with the expected UV-to-X-ray spectral slope relation, while three show evidence for relative X-ray weakness. These results reveal diverse X-ray properties among broad-line AGNs in low-mass galaxies and highlight the importance of multiwavelength diagnostics for understanding black hole accretion and interpreting broad-line AGN candidates at high redshift.",
