AGN photoionization of gas in companion galaxies
We consider active galactic nucleus (AGN) photoionization of gas in companion galaxies (cross-ionization) as a way to sample the intensity of AGN radiation in both direction and... -
WISE view of narrow-line Seyfert 1 galaxies
We present the colour and flux variability analysis at 3.4{mu}m (W1 band) and 4.6{mu}m (W2 band) of 492 narrow-line Seyfert 1 (NLSy1) galaxies using archival data from the... -
Nearby Seyfert galaxies FIR emissions
We present far-infrared (FIR) 70-500{mu}m imaging observations obtained with Herschel/Photodetector Array Camera (PACS) and Spectral and Photometric Imaging REceiver (SPIRE) of... -
FeK lines in Seyfert 1 galaxies
We construct full broad-band models in an analysis of Suzaku observations of nearby Seyfert 1 active galactic nuclei (AGN) (z<=0.2) with exposures >50ks and with greater... -
X-ray obs. of narrow- and broad-line Seyfert 1 gal.
We present a detailed comparative systematic study using a sample of 221 narrow-line Seyfert 1 (NLSy1) galaxies in comparison to a redshift-matched sample of 154 broad-line... -
1H 0323+342 rest frame optical spectrum with GHAO
We present optical and near-infrared (NIR) imaging data of the radio-loud, narrow-line Seyfert 1 galaxy 1H 0323+342, which shows intense and variable gamma-ray activity... -
Reverberation mapping of the Seyfert 1 NGC 7469
A large reverberation-mapping study of the Seyfert 1 galaxy NGC 7469 has yielded emission-line lags for H{beta} {lambda}4861 and He II {lambda}4686 and a central black hole mass... -
LOFAR Bootes and 3C295 field sources
We present Low Frequency Array (LOFAR) Low Band observations of the Bootes and 3C 295 fields. Our images made at 34, 46, and 62 MHz reach noise levels of 12, 8, and 5 mJy/beam,... -
Chandra X-ray sources of NGC 1068
We present an analysis of the compact X-ray source population in the Seyfert 2 galaxy NGC 1068, imaged with a 50ks Chandra observation. We find a total of 84 compact sources on... -
HST COS spectrum of I Zwicky 1
We present an analysis of the Hubble Space Telescope Cosmic Origins Spectrograph spectrum of IZw1 aiming to probe the absorbing medium associated with the active galactic... -
NGC1068 I-HCN(1-0) and I-HCO+(1-0) maps
The current understanding of star formation (SF) contemplates that the regulation of this phenomenon in galaxy disks reflects a complex balance between processes that operate in... -
Turin-SyCAT, Seyferts multifrequency catalog
We present the first release of Turin-SyCAT, a multifrequency catalog of Seyfert galaxies. We selected Seyfert galaxies considering criteria based on radio, infrared, and... -
HST/COS and FUSE UV spectra of Mrk 509
To elucidate the location, physical conditions, mass outflow rate, and kinetic luminosity of the outflow from the active nucleus of the Seyfert 1 galaxy Mrk 509 we used... -
Warm ISM in the Sagittarius A Complex
We investigate the spatial and spectral distribution of the local standard of rest (LSR) velocity resolved submillimetre emission from the warm (25-90K) gas in the Sgr A... -
Core dominance in extragalactic radio sources
In this paper, based on a paper by Liu and Zhang (2002, Cat. ), we have chosen a sample of 542 extragalactic sources (27 BL Lac objects, 300 galaxies (radio galaxies and Seyfert... -
NLS1 galaxy 1H 0323+342 Xray, UBV, UV, gamma data
We present a comprehensive investigation into the properties of 1H 0323+342, a prominent jetted narrow-line Seyfert 1 galaxy. The primary objective is to understand the... -
X-ray of active galaxies and nuclei
(no description available) Cone search capability for table VII/181/table2 (Catalog for PG Quasars) Cone search capability for table VII/181/table3 (Catalog for Seyfert 1 and... -
Catalogue of Seyfert Galaxies
A list of 959 Seyfert galaxies whose data were obtained up to the beginning of 1987 is compiled. Coordinates, redshifts, UBVR-photoelectric magnitudes, absolute magnitudes,... -
Michigan Emission-Line Objects
The objects of this catalogue were detected by using the 61-cm aperture Curtis Schmidt telescope in combination with a thin objective prism (1.8{deg}) at the Cerro Tololo... -
The Extended 12um galaxy sample
The authors have used the IRAS data to compile a sample of 893 galaxies, including 118 Seyfert galaxies. Please refer to the "12micron.doc" (ascii) or "12micron.tex" (LaTeX)...
