We study the size of broad-line regions (BLRs) of low-luminosity active galactic nuclei (AGN), also called 'dwarf AGN',defined as having L Hα ≤ 10 41 erg s- 1 . We more than double the sample size analysed previously by Wang & Zhang. In this study we first confirm our previous result -that the sizes of BLRs of low-luminosity AGN are larger than those expected from the empirical relation R BLRs -L Hα valid for 'normal' AGN (Seyfert Is and quasars), except for objects with accretion rate m H…

The sizes of broad emission line regions and black hole masses of double‐peaked broad low‐ionization emission line objects
In this paper, the sizes of the broad emission line regions (BLRs) and black hole (BH) masses of double-peaked broad low-ionization emission line emitters (DBP emitters) are compared using different
The HST view of the broad line region in low luminosity AGN
We analyze the properties of the broad line region (BLR) in low luminosity AGN by using HST/STIS spectra. We consider a sample of 24 nearby galaxies in which the presence of a BLR has been reported
Giant Broad Line Regions in Dwarf Seyferts
High angular resolution spectroscopy obtained with the Hubble Space Telescope (HST) has revealed a remarkable population of galaxies hosting dwarf Seyfert nuclei with an unusually large broad-line
Partly obscured accretion disc model to explain shifted broad Balmer emission lines of active galactic nuclei
We present a new model to explain the appearance of red/blueshifted broad low-ionization emission lines, especially emission lines in the optical band, which is commonly considered as an indicator of
The correlation between spectral index and accretion rate for AGN
In this paper, we present a correlation between the spectral index distribution (SED) and the dimensionless accretion rate defined as m = L bol /L Edd for active galactic nuclei (AGN). This quantity

We have conducted a new spectroscopic survey to characterize the nature of nuclear activity in Hickson compact group (HCG) galaxies and establish its frequency. We have obtained new
Nuclear Activity in Nearby Galaxies
A significant fraction of nearby galaxies show evidence of weak nuclear activity unrelated to normal stellar processes. Recent high-resolution, multiwavelength observations indicate that the bulk of

‘Disc–Jet’ Coupling in Black Hole X-Ray Binaries and Active Galactic Nuclei
In this chapter I will review the status of our phenomenological understanding of the relation between accretion and outflows in accreting black hole systems. This understanding arises primarily from
Subaru and e-Merlin observations of NGC 3718. Diaries of a supermassive black hole recoil?
NGC3718 is a LINER $L1.9$ galaxy, lying at a distance of about $\sim 17.4$ Mpc away from earth and its similarities with NGC5128 often award it the name "northern Centaurus A". We use high angular

An empirical relation between the broad line region (BLR) size and optical continuum luminosity is often adopted to estimate the BLR size and then the black hole mass of AGNs. However, optical
