A blind Green Bank Telescope millimetre-wave survey for redshifted molecular absorption
N. Kanekar, A. Gupta, C. L. Carilli +2
We present the methodology for ``blind'' millimetre-wave surveys for redshifted molecular absorption in the CO/HCO rotational lines. The frequency range GHz appears opt…

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…
