We present results from Chandra HETGS ( 250 ks over two epochs ) and XMM-Newton EPIC and RGS ( 60 ks ) observations of NGC 2110 , which has been historically classified as a Narrow Emission Line Galaxy galaxy .
Our results support the interpretation that the source is a Seyfert 2 viewed through a patchy absorber .
The nuclear X-ray spectrum of the source is best described by a power law of photon index \Gamma \sim 1.7 , modified by absorption from multiple layers of neutral material at a large distance from the central supermassive black hole .
We report the strong detections of Fe K \alpha and Si K \alpha lines , which are marginally resolved with the Chandra HETGS , and we constrain the emission radius of the fluorescing material to \mathrel { \hbox to 0.0 pt { \raise 2.15 pt \hbox { $ > $ } } { \lower 2.15 pt \hbox { $ \sim$ } } } 1 pc .
There is some evidence for modest additional broadening at the base of the narrow Fe K \alpha core with a velocity \sim 4500 km s ^ { -1 } .
We find tentative evidence for ionized emission ( O viii Ly \alpha , an O viii RRC feature , and possibly a Ne ix forbidden line ) in the Chandra MEG and XMM-Newton RGS spectra , which could be associated with the known extended X-ray emission that lies \sim 160 pc from the nucleus .
We suggest that the 10 ^ { 23 } cm ^ { -2 } partially covering absorber originates in broad-line region clouds in the vicinity of the AGN , and that the 3 \times 10 ^ { 22 } cm ^ { -2 } coverer is likely to have a more distant origin and have a flattened geometry in order to allow the small-scale radio jet to escape .
