VLBI and VLA obs. of Seyfert galaxies
We have obtained mas-scale resolution very long baseline interferometry (VLBI) images of a sample of Seyfert 1 and Seyfert 2 galaxies at 5GHz (wavelength, {lambda}=6cm). The... -
AGNs from RXTE 3-20keV All-Sky Survey
We compiled a sample of 95 AGNs serendipitously detected in the 3-20keV band at Galactic latitude |b|>10deg during the RXTE slew survey (XSS, Revnivtsev et al., Cat. ), and... -
Mid-infrared and hard X-ray emission in AGN
We use mid-infrared spectral decomposition to separate the 6{mu}m mid-infrared AGN continuum from the host emission in the ISO low resolution spectra of 71 active galaxies and... -
Radio Emission from VLA FIRST Survey AGN
Using the most recent (April 2003) version of the VLA FIRST survey radio catalog (Cat. ), we have searched for radio emission from >2800 AGN taken from the most recent (2001)... -
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... -
QSOs in the M3 field
We present results from a variability and proper motion (VPM) search for QSOs in the field around M3. The VPM search is demonstrated to be powerful technique for efficiently... -
The Hamburg/SAO Survey for ELGs. V.
We present the fifth list with results of the Hamburg/SAO Survey for Emission-Line Galaxies (HSS therein, SAO - Special Astrophysical Observatory, Russia). The list is a result... -
NGC 5548 UBVRI phot. and Halpha, Hbeta fluxes
Results of a ground-based optical monitoring campaign on NGC 5548 in June 1998 are presented. The broad-band fluxes (U, B, V), and the spectrophotometric optical continuum flux... -
Monitoring Mkn 279 in BVRI and H{beta} fluxes
Mid-infrared images of the Seyfert 1 galaxy Mrk 279 obtained with the ISO satellite are presented together with the results of a one-year monitoring campaign of the... -
The Hamburg/SAO Survey for ELGs. IV
We present the fourth list with results of the Hamburg/SAO Survey for Emission-Line Galaxies (HSS hereafter, SAO -- Special Astrophysical Observatory, Russia). The main goal of... -
Hamburg/ESO survey for bright QSOs. III.
Appendix to the above paper, containing the two large tables A.1 and B.1 described in the paper. Table A.1 gives the basic properties of the 207 survey fields used to construct... -
NGC 4151 line-continuum diagram sequences
We present the first results of an 8-year spectroscopic monitoring of the Seyfert 1.5 galaxy NGC 4151 carried out with a CCD spectrograph at the 2.6-m Shajn Telescope of the... -
NGC 5548 continuum light curve
The variations of the [OIII]{lambda}5007 line profile in NGC 5548 are examine d from CCD spectra obtained at the Ohio State University and Crimean Astrophysic al Observatory in... -
NGC 5548 Profile variability
Optical emission line intensities of the variable Seyfert 1 galaxy NGC 5548 are presented. -
An Ultraviolet Atlas of Quasar and Blazar Spectra
This atlas contains the ultraviolet spectra of 70 quasars, blazars, and Seyfert 1 galaxies that were produced by combining over 100 low resolution spectra from the International... -
Sasmirala Subarcsecond mid-infrared atlas of local AGN
These FITS images were generated with the IDL package MIRphot [Asmus2014] by extraction (and combination) of the sub-images from the chopped/nodded total images from COMICS,... -
Sasmirala Subarcsecond mid-infrared atlas of local AGN, Cone Search
The Subarcsecond mid-infrared (MIR) atlas of local active galactic nuclei (AGN) is a collection of all available N- and Q-band images obtained at ground-based 8-meter class... -
Radio and {Gamma}-ray of MOJAVE-Fermi AGNs
Within the MOJAVE VLBA programme (Monitoring of Jets in AGN with VLBA Experiments), we have accumulated observational data at 15 GHz for hundreds of jets in gamma-ray bright... -
Multiwavelength properties of unobscured AGN
We present one of the largest multiwavelength studies of simultaneous optical-to-X-ray spectral energy distributions (SEDs) of unobscured (N_H<10^22cm^-2) active galactic... -
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...
