The complex structure of low-luminosity active galactic nuclei: NGC 4579 [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 We have modelled the low-luminosity active galactic nucleus (AGN) NGC 4579 by explaining both the continuum and the line spectra observed with different apertures. It was found that the nuclear emission is dominated by an AGN such that the flux from the active centre (AC) is relatively low compared with that of the narrow emission-line region (NLR) of ...

Multiple Emission Regions in Jets of the Low-Luminosity Active Galactic Nucleus in NGC 4278
The Astrophysical JournalThe Large High Altitude Air Shower Observatory (LHAASO) has detected very-high-energy gamma rays from the low-ionization nuclear emission-line region galaxy NGC 4278, which has a low-luminosity active galactic nucleus (LLAGN) and symmetric, mildly ...

The DELVE Quadruple Quasar Search. I. A Lensed Low-luminosity Active Galactic Nucleus
The Astronomical JournalA quadruply lensed source, J125856.3–031944, has been discovered using the DELVE survey and Wide-field Infrared Survey Explorer W1–W2 colors. Follow-up direct imaging carried out with the Magellan Baade 6.5 m telescope is analyzed, as is spectroscopy ...

Polarimetry of Black Hole Spin and Axisymmetric Emission Geometry
The Astrophysical JournalThe Event Horizon Telescope array has measured the average polarimetric spiral morphology of black hole accretion disks using the so-called β _2 coefficient. This measurement is dominated by the weakly lensed, direct ( n = 0, counting photon half-orbits)

ReveaLLAGN 0: First Look at JWST MIRI Data of Sombrero and NGC 1052
The Astrophysical JournalWe present the first results from the Revealing Low-Luminosity Active Galactic Nuclei (ReveaLLAGN) survey, a JWST survey of seven nearby LLAGNs. We focus on two observations with the Mid-Infrared Instrument (MIRI)’s Medium-Resolution Spectrometer of the ...

The Astrophysical JournalReliable identification of ongoing nuclear activity in nearby galaxies is challenging when central regions are heavily obscured, especially for low-luminosity active galactic nuclei (AGN) whose emission can also be contaminated by the host galaxy.
