Far-infrared properties of optically-selected quasars and Seyfert galaxies [PDF]

Pointed IRAS observations and ground based observations are used to determine the infrared properties of optically selected galaxies and quasars. The use of complete, unbiased, optically selected samples means that statistical tests can be applied to ...

Two 100 TeV Neutrinos Coincident with the Seyfert Galaxy NGC 7469

The Astrophysical Journal
In 2013, the IceCube collaboration announced the detection of a diffuse high-energy astrophysical neutrino flux. The origin of this flux is still largely unknown. The most significant individual source is the close-by Seyfert galaxy NGC 1068 at the 4.2 σ

X-ray Properties of Two Complementary Samples of Intermediate Seyfert Galaxies

Universe
We present the X-ray spectral analysis of two complementary sets of intermediate Seyfert galaxies (ISs). Analyzing X-ray data, we estimate the hydrogen abundance NH and test its connection with the [O III] luminosity acquired from optical observations ...
