Abstract

Chandra observations of NGC 4258 were analyzed to investigate the circumnuclear environment of the HO megamaser galaxy. Its adaptively-smoothed image shows a bright nucleus and another weak source nearby. For the maser host nucleus, our preferred fitting of its spectra gives the absorption of ~7×10cm.
