We report the discovery of the 10 kilo-parsec (kpc) scale radio lobes in theSombrero galaxy (NGC 4594), using data from the Continuum Halos in NearbyGalaxies - an Expanded Very Large Array (VLA) Survey (CHANG-ES) project. Wefurther examine the balance between the magnetic pressure inside the lobes andthe thermal pressure of the ambient hot gas. At the radii $r$ of ~(1-10) kpc,the magnetic pressure inside the lobes and the thermal pressure of the ambienthot gas are generally in balance. This implies that the jets could expand intothe surroundings at least to r ~ 10 kpc. The feedback from the active galacticnucleus (AGN) jet responsible for the large-scale lobes may help to explain theunusually high X-ray luminosity of this massive quiescent isolated disk galaxy,although more theoretical work is needed to further examine this possibility.

We investigate the baryonic Tully-Fisher relation in low surface brightnessgalaxies selected from the Arecibo Legacy Fast ALFA survey. We find that the$\rm HI$-bearing low surface brightness galaxies still follow the baryonicTully-Fisher relation of typical late-type galaxies, with a slope ofapproximately 4 in the baryonic mass versus rotational velocity diagram on thelogarithmic scale, i.e., $M_{\rm{b}}\propto v_{\rm{rot}}^4$. Our findingssuggest that the matter distributions in low surface brightness galaxies mayresemble that of general late-type galaxies, and hint that low surfacebrightness galaxies may not originate from dark matter halos of low densitiesor stronger/weaker feedback processes, but may emerge from dark matter haloswith high spin values.
