Emission and Absorption Properties of Low-Mass Type 2 Active Galaxies with XMM-Newton (2009)
Thornton, C. E., Barth, A. J., Ho, L. C., Greene, J. E.
We present XMM-Newton observations of four low-redshift Seyfert galaxies selected to have low host luminosities (M_g>-20 mag) and small stellar velocity dispersions (sigma_star
Structure of the accretion flow in broad-line radio galaxies: the case of 3C 390.3 (2009)
Sambruna, R. M., Reeves, J. N., Braito, V., Lewis, K. T., Eracleous, M., Gliozzi, M., ...
We present XMM-Newton and Suzaku observations of the broad-line radio galaxy 3C 390.3 acquired in 2004 October and 2006 December, respectively. An archival Swift BAT spectrum from the 9 month survey...
Structure of the Accretion Flow in Broad-Line Radio Galaxies: The Case of 3C390.3 (2009)
Sambruna, R. M., Reeves, J. N., Braito, V., Lewis, K. T., Eracleous, M., Gliozzi, M., ...
We present XMM and Suzaku observations of the Broad-Line Radio Galaxy (BLRG) 3C390.3. The Fe Ka line has a width FWHM ~ 8,800 km/s, consistent within a factor two with the width of the double-peaked...
Barth, A. J., Strigari, L. E., Bentz, M. C., Greene, J. E., Ho, L. C.
NGC 3621 is a late-type (Sd) spiral galaxy with an active nucleus, previously detected through mid-infrared [Ne V] line emission. Archival Hubble Space Telescope (HST) images reveal that the galaxy...
An Offset Seyfert 2 Nucleus in the Minor Merger System NGC 3341 (2008)
Barth, A. J., Bentz, M. C., Greene, J. E., Ho, L. C.
We present the discovery of a triplet of emission-line nuclei in the disturbed disk galaxy NGC 3341, based on archival data from the Sloan Digital Sky Survey and new observations from the Keck...
Low-Mass Seyfert 2 Galaxies in the Sloan Digital Sky Survey (2008)
Barth, A. J., Greene, J. E., Ho, L. C.
(Abridged) We describe a sample of low-mass Seyfert 2 galaxies selected from the Sloan Digital Sky Survey, having a median absolute magnitude of M_g = -19.0 mag. These galaxies are Type 2...
The Host Galaxy and Central Engine of the Dwarf AGN POX 52 (2008)
Thornton, C. E., Barth, A. J., Ho, L. C., Rutledge, R. E., Greene, J. E.
We present new multi-wavelength observations of the dwarf Seyfert 1 galaxy POX 52 in order to investigate the properties of the host galaxy and the active nucleus, and to examine the mass of its...
A Normal Stellar Disk in the Galaxy Malin 1 (2006)
Since its discovery, Malin 1 has been considered the prototype and most extreme example of the class of giant low surface brightness disk galaxies. Examination of an archival Hubble Space Telescope...
Dwarf Seyfert 1 Nuclei and the Low-Mass End of the M-sigma Relation (2004)
Barth, A. J., Greene, J. E., Ho, L. C.
To examine the relationship between black hole mass and host galaxy velocity dispersion for low black hole masses, we have measured the velocity dispersions of 15 Seyfert 1 galaxies from the catalog...
Black holes as traced by weak active nuclei (2004)
Shields, J. C., Barth, A. J., Filippenko, A. V., Ho, L. C., McIntosh, D. H., ...
The survey of nearby nuclei with STIS (2003)
Shields, J. C., Sarzi, M., Ho, L. C., Barth, A. J., McIntosh, D. H., ...
This paper will summarize results from a spectroscopic survey of a volume-limited sample of 23 nearby galaxies selected on the basis of nebular emission in their nuclei. Data acquired with STIS on...
Dietrich, M., Peterson, B.M., Albrecht, P., Altmann, M., Barth, A.J., Bennie, P.J., ...
Results of a ground-based optical monitoring campaign on 3C 390.3 in 1994-1995 are presented. The broadband fluxes (B, V , R, and I), the spectrophotometric optical continuum flux Fλ(5177 Ã ),...
