A Multi-Wavelength Search for AGNs in Low-Mass Galaxies from the MaNGA Survey
Abstract
Understanding AGN feedback in low-mass galaxies is crucial for constraining SMBH growth across cosmic time. Since these galaxies likely resemble the primordial building blocks of more massive systems, understanding AGN activity in low-mass hosts offers a unique window into the early phases of SMBH growth. We investigate AGN activity in 27 galaxies with $M_* < 5 \times 10^9,M_\odot$, combining MaNGA data with multi-wavelength AGN selection: mid-IR (WISE), X-ray (Swift/BAT, eROSITA), and radio (NVSS/FIRST). The recent eROSITA data (Sep 2024 release) are particularly effective at revealing obscured AGNs missed by optical diagnostics, expanding our initial sample from 16 to 27 candidates.
