Chandra Data Analysis of H2O Megamaser Galaxy NGC 4258

摘要：

Chandra observations of NGC 4258 were analyzed to investigate the circumnuclear environment of the H2O 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 ～7x 1022cm-2.
