Shock Excitation in Narrow Line Regions Powered by AGN Outflows
Misaki Mizumoto, Hiroaki Sameshima, Naoto Kobayashi +10
Outflows in the Active Galactic Nucleus (AGN) are considered to play a key role in the host galaxy evolution through transfer of a large amount of energy. A Narrow Line Region (NLR…
Simple interpretation of the seemingly complicated X-ray spectral variation of NGC 5548
Takuya Midooka, Ken Ebisawa, Misaki Mizumoto +1
NGC 5548 is a very well-studied Seyfert 1 galaxy in broad wavelengths. Previous multiwavelength observation campaigns have indicated that its multiple absorbers are highly variable…
Absorption Lines in the 0.91-1.33 m Spectra of Red Giants for Measuring Abundances of Mg, Si, Ca, Ti, Cr, and Ni
K. Fukue, N. Matsunaga, S. Kondo +13
Red giants show a large number of absorption lines in both optical and near-infrared wavelengths. Still, the characteristics of the lines in different wave passbands are not necess…
Mg II and Fe II fluxes of luminous quasars at z ~ 2.7 and evaluation of the Baldwin effect in the flux-to-abundance conversion method for quasars
Hiroaki Sameshima, Yuzuru Yoshii, Noriyuki Matsunaga +12
To investigate the chemical abundance of broad-line region clouds in quasars at high redshifts, we performed near-infrared spectroscopy of six luminous quasars at z ~ 2.7 with the…
Geometry of the X-ray source 1H 0707-495
Michal Szanecki, Andrzej Niedzwiecki, Chris Done +3
We investigate constraints for the size and location of the X-ray source in 1H 0707-495 determined from the shape of the relativistically smeared reflection from the accretion disc…
Testing The Lamp-Post and Wind Reverberation Models with XMM-Newton Observations of NGC 5506
Abderahmen Zoghbi, Sihem Kalli, Jon M Miller +1
The lamp-post geometry is often used to model X-ray data of accreting black holes. Despite its simple assumptions, it has proven to be powerful in inferring fundamental black hole…
