Discovery of Relativistic Outflow in the Seyfert Galaxy Ark 564
A. Gupta, S. Mathur, Y. Krongold +1
We present \chandra high energy transmission grating spectra of the narrow-line Seyfert-1 galaxy Ark 564. The spectrum shows numerous absorption lines which are well modeled with l…

A Two-Phase Low-velocity Outflow in the Seyfert 1 Galaxy Ark~564
A. Gupta, S. Mathur, Y. Krongold +1
The Seyfert 1 galaxy Ark 564 was observed with Chandra high energy transmission gratings for 250 ks. We present the high resolution X-ray spectrum that shows several associated abs…

A huge reservoir of ionized gas around the Milky Way: Accounting for the Missing Mass?
A. Gupta, S. Mathur, Y. Krongold +2
Most of the baryons from galaxies have been "missing" and several studies have attempted to map the circumgalactic medium (CGM) of galaxies in their quest. Recent studies with the…
