Atlas of HST STIS spectra of Seyfert galaxies
We present a compilation of spectra of 101 Seyfert galaxies obtained with the Hubble Space Telescope (HST) Space Telescope Imaging Spectrograph (STIS), covering the UV and/or... -
IRAS 1Jy sample of ultraluminous galaxies. II.
An R and K' atlas of the IRAS 1 Jy sample of 118 ultraluminous infrared galaxies (ULIGs) was presented in a companion paper (our Paper I, Kim et al., 2002, Cat. ). The present... -
IRAS 1Jy sample of ultraluminous galaxies. I.
An imaging survey of the IRAS 1Jy sample of 118 ultraluminous infrared galaxies was conducted at optical (R) and near-infrared (K') wavelengths using the University of Hawaii... -
VLA radio continuum survey of Seyfert galaxies
We have used the Very Large Array (VLA) to conduct a survey for radio continuum emission in the sample of 52 Seyfert nuclei selected from the optical spectroscopic galaxy... -
Morphology of 12micron Seyfert Galaxies
We present 263 optical and near-infrared (NIR) images for 42 1s and 48 Seyfert 2s, selected from the Extended 12{mu}m Galaxy Sample. Elliptically averaged profiles are derived... -
Universidad Complutense de Madrid list 3
A new low-dispersion objective-prism search for low-redshift (z<0.045) emission-line galaxies (ELGs) has been carried out by the Universidad Complutense de Madrid using the... -
A diagnostic diagram for Seyfert 2 Galaxies
We present and discuss a three-dimensional diagnostic diagram for Seyfert 2 galaxies obtained using X-ray and [O III] data on a large sample of objects (reported in the... -
Spectroscopic parameters of Seyfert nuclei
We have completed an optical spectroscopic survey of the nuclear regions (r<=200pc) of a large sample of nearby galaxies. Although the main objectives of the survey are to... -
Seyfert 2 galaxies multiwavelength catalog
This paper is a catalog of Seyfert 2 galaxies observed in the 2-10keV band (339 flux entries). In total, it contains data on 150 objects; for 76 objects, a positive detection is... -
H II Regions in Nearby Seyfert Galaxies
Continuum-subtracted Halpha images of 17 nearby Seyfert galaxies are presented. The images are calibrated astrometrically using the Hubble Space Telescope Guide Star Catalog... -
Universidad Complutense de Madrid list 2
A low dispersion objective-prism survey for low-redshift emission-line galaxies (ELGs) is being carried out by the University Complutense de Madrid with the Schmidt telescope at... -
H II Regions in Seyfert galaxies. I.
Data on positions, effective diameters, and absolute fluxes of H II regions on 21 Seyfert spiral galaxies are presented together with the H{alpha} + [N II] images and... -
Spectroscopy and photometry follow up for NGC 4151
Changing-look active galactic nucleus NGC4151, which has attracted a lot of attention, is undergoing the second dramatic outburst stage in its evolutionary history. To... -
Seyfert 1 AGNs with X-ray sp. from NuSTAR+Swift
The corona is an integral component of active galactic nuclei (AGNs) which produces the bulk of the X-ray emission above 1-2keV. However, many of its physical properties and the... -
LAMP 2016: velocity-resolved Hb lags in Seyfert gal.
We carried out spectroscopic monitoring of 21 low-redshift Seyfert 1 galaxies using the Kast double spectrograph on the 3m Shane telescope at Lick Observatory from 2016 April to... -
Reverberation mapping for Mrk 817 and NGC 7469
We present the results from a spectroscopic monitoring campaign to obtain reverberation mapping measurements and investigate the broad-line region (BLR) kinematics for active... -
Feedback from outflows in AGNs. III. Mrk78
Outflows of ionized gas driven by active galactic nuclei (AGN) may significantly impact the evolution of their host galaxies. However, determining the energetics of these... -
Follow-up photometry of ASASSN-14ko
We present the discovery that ASASSN-14ko is a periodically flaring active galactic nucleus at the center of the galaxy ESO 253-G003. At the time of its discovery by the All-Sky... -
