,The host galaxy of BL Lac objects or what’s in a name?,ontains mostly medium bright radio galaxies. This analysis leads us to suggest that radio galaxies such as those of the B2 bright sample form the parent population of nearby BL Lac objects. Confirmation of this model requires the identification and observation of a larger number of nearby BL Lac obj作者: Crepitus 時間: 2025-3-22 06:39

Anisotropic ionising continuum emission in AGNs,N. The anisotropy of the ionising continuum, evident from very extended and very narrow [OIII] line emission, appears correlated with the nuclear radio axis. Further information on anisotropy may be obtained from the detailed associations between [OIII] features and radio components observed in AGNs作者: Humble 時間: 2025-3-22 22:47 作者: 拾落穗 時間: 2025-3-23 03:43

Radio variability of BL Lacs and related objects: Observations vs. shocked jet models,The properties of compact extragalactic radio sources are investigated using a sample of 27 sources extensively observed at millimeter frequencies.

Handbook of Neuropsychology and AgingFrom a purely statistical point of view this might be due to their being the low-. tail of the quasar distribution; this also would help to explain the rapid intensity variations and high continuum/line ratios.

An optical polarization survey for BL Lacs,te, forty candidates from 72 square degrees of the sky have been followed up spectroscopically. A quasar with a redshift of z = 1.42 was found. We consider it a strong candidate to be a highly polarized quasar. Two candidate BL Lacs, objects with apparently featureless spectra, were also found.作者: 偏離 時間: 2025-4-1 12:36
