A compact symmetric ejection from the low mass AGN in the LINER galaxy NGC 4293

We conducted a Very Long Baseline Array (VLBA) observation of the low mass active galactic nucleus (AGN) in galaxy NGC 4293 ($z=0.003$). The object is associated with low-ionization nuclear emission-line region (LINER). Its black hole estimated as $\sim10^5$ or $\sim10^7 M_\odot$. VLBA 1.5 GHz image shows an inverse symmetric structure two discrete radio blobs separated by angular distance $\sim120$ mas, corresponding to $\sim7$ parsec. Furthermore, its integrated spectrum has turnover at frequency $\sim0.44$ GHz. Based on compactness and spectrum, source belongs sample (megahertz) peaked (PS/MPS) sources compact morphologies. 1.4 power only $\sim10^{20}\,\mathrm{W\,Hz^{-1}}$ observation, which consistent local AGNs but lower than current PS samples. One steep $\alpha=-0.62\pm0.08$ ($S_\nu\propto\nu^{+\alpha}$), while other one inverted $\alpha=0.32\pm0.10$. luminosity ratio 3.23 both show lateral-flowing structures where hotspots reside edge each lobe. This can be explained jet interactions dense circumnuclear medium. estimate through fundamental plane activity, constrains $\lesssim10^6 It supports that low-mass AGN potential candidate for accreting ejecting IMBHs.
