XMM - Newton VIEW OF THE PROTOTYPE NARROW - LINE SEYFERT 1 GALAXY I ZW 1
We present results based on an XMM-Newton observation of the prototype narrow-line Seyfert 1 galaxy I Zw 1 performed in June 2002. The 0.6−12 keV spectrum is well described by a steep power-law (Γ ∼ 2.3) and a weak soft blackbody component (kT ∼ 200 eV) below 2 keV. The soft X-ray excess emission is featureless and contributes only ∼ 10% to the total X-ray emission in the 0.6− 2 keV band. There...
متن کاملAn Empirical Ultraviolet Template for Iron Emission in Quasars as Derived from I Zw 1
We present an empirical template spectrum suitable for fitting and subtract-ing/studying the Fe ii and Fe iii emission lines in the restframe ultraviolet spectra of quasars and active galatic nuclei, the first empirical ultraviolet iron template to cover the full range of λ1250−3090Å. Iron emission is often a severe contaminant in optical– ultraviolet spectra of active galactic nuclei and quasa...
متن کاملThe Nature Of Radio Continuum Emission At Very Low Metallicity : VLA Observations of I Zw 18
We present the first resolved study of the radio continuum properties of I Zw18, the dwarf galaxy with the lowest known nebular metal abundance in the local universe. New Very Large Array radio continuum images at 20 and 3.6 cm are compared to various Hubble Space Telescope images, and we find a striking morphological similarity between high resolution Hα and short wavelength radio continuum em...
متن کاملHE 0141 – 3932 : a bright QSO with an unusual emission line spectrum and associated absorption ⋆
HE 0141–3932 (zem = 1.80) is a bright blue radio-quite quasar with an unusually weak Lyα emission line. Large redshift differences (∆z = 0.05) are observed between high ionization and low ionization emission lines. Absorption systems identified at z abs = 1.78, 1.71, and 1.68 show mild oversolar metallicities (Z ≈ 1 − 2Z⊙) and can be attributed to the associated gas clouds ejected from the circ...
متن کاملH I observations of emission - line galaxies
We present single-dish Lovell telescope H i observations of a sample of 67 emission-line and UV-excess galaxies, of which 52 are taken from the University of Michigan (UM) catalogue. In addition, H i observations of 24 gas-rich irregular galaxies are presented. We find that emission-line galaxies are H i–rich with a median H i mass to blue luminosity ratio MHI /LB of ∼ 0.45 M /L . Within the UM...
