M-BH - sigma relation for a Complete Sample of Soft X-ray Selected AGNs
Dirk Grupe, Smita Mathur
We present black hole mass--bulge velocity dispersion relation for a complete sample of 75 soft X-ray selected AGNs: 43 broad line Seyfert 1s and 32 narrow line Seyfert 1s. We use…
X-Ray Sources Overdensity Around the 3C 295 Galaxy Cluster
V. D'Elia, F. Fiore, M. Elvis +4
We present a statistical analysis of the Chandra observation of the source field around the 3C 295 galaxy cluster (). The logN-logS of this field is in good agreement with…
X-Ray Sources Overdensity Around 3C 295
V. D'Elia, F. Fiore, M. Elvis +4
We present a statistical analysis of the Chandra observation of the source field around the 3C 295 galaxy cluster (). Three different methods of analysis, namely a chip by…
The Ionized Gas and Nuclear Environment in NGC 3783 III. Detection of a Decreasing Radial Velocity in an Intrinsic UV Absorber
J. R. Gabel, D. M. Crenshaw, S. B. Kraemer +14
We report an intrinsic absorber with decreasing outflow velocity in the Seyfert 1 galaxy NGC 3783. This is the first detection of a change in radial velocity in an outflow associat…
XMM-Newton Observations of Two BAL QSOs: Q1246-057 and SBS1542+541
D. Grupe, S. Mathur, M. Elvis
We report on the results of XMM-Newton observations of two Broad Absorption Line Quasars (BAL QSOs), Q1246-057 and SBS 1542+541. Unprecedented sensitivity of XMM allows spectral an…
Chandra discovery of the intracluster medium around UM425 at redshift 1.47
Smita Mathur, Rik J. Williams
We report on a discovery of a candidate cluster of galaxies at redshift z=1.47 based on Chandra observations in the field of quasars UM425 A & B. We detect with high significance d…
