UBVRcIc photometry in fields of Seyfert galaxies
We present UBVRcIc magnitudes of 49 comparison stars in the fields of the Seyfert galaxies Mrk 335, Mrk 79, Mrk 279, Mrk 506, 3C 382, 3C 390.3, NGC 6814, Mrk 304, Ark 564, and... -
Matched SDSS and FIRST Sample
The question as to whether the distribution of radio loudness in active galactic nuclei (AGNs) is actually bimodal has been discussed extensively in the literature. Furthermore,... -
Narrow-line Seyfert 1 galaxies from SDSS EDR
We present a sample of 150 narrow-line Seyfert 1 galaxies (NLS1's) found within the Sloan Digital Sky Survey (SDSS) Early Data Release (EDR) (Stoughton et al.,... -
NGC 6221 ionized gas kinematics
Rotation curves and velocity dispersion profiles are presented for both the stellar and gaseous components along five different position angles (PA =5{deg}, 50{deg}, 95{deg},... -
Warm IRAS sources. IV.
We present a list of objects observed to have extended line emission in our spectroscopic survey of infrared-warm AGN. Slit spectroscopic data were obtained for 225 galaxies... -
12CO and HCN datacubes of NGC 253
Investigating molecular gas tracers, such as hydrogen cyanide (HCN), to probe higher densities than CO emission across nearby galaxies remains challenging. This is due to the... -
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... -
Origins of radio emission in NLS1s
Narrow-line Seyfert 1 galaxies (NLS1s) are believed to be active galactic nuclei (AGN) in the early stages of their evolution. Several dozen of them have been found to host... -
X-ray absorption in INTEGRAL AGN
In this work the INTEGRAL hard X-ray selected sample of AGN has been used to investigate the possible contribution of absorbing material distributed within the host galaxies to... -
Mrk 231 CO(1-0) and CN(1-0) line observations
We present interferometric observations of the CN(1-0) line emission in Mrk 231 and combine them with previous observations of CO and other H_2_ gas tracers to study the... -
NGC4388 and NGC2110 spectral files
We aim to measure the physical properties of the hot X-ray corona of two active galactic nuclei, NGC 4388 and NGC 2110. We analysed the hard X-ray (20-300keV) INTEGRAL spectrum... -
LOFAR 143MHz images of 3C 236
We have examined the giant radio galaxy 3C 236 using LOFAR at 143MHz down to an angular resolution of 7 arcseconds, in combination with observations at higher frequencies. We... -
MAGNUM survey galaxies images
We investigate the interstellar medium (ISM) properties of the disk and outflowing gas in the central regions of nine nearby Seyfert galaxies, all characterised by prominent... -
SINFONI datacube of NGC 1365
In the framework of understanding the gas and stellar kinematics and their relations to AGNs and galaxy evolution scenarios, we present spatially resolved distributions and... -
NLS1 at 37GHz
We have detected six narrow-line Seyfert 1 (NLS1) galaxies at 37GHz that were previously classified as radio silent and two that were classified as radio quiet. These detections... -
37 GHz observations of NLS1 galaxies
Observations performed at Metsahovi Radio Observatory at 37GHz are presented for a sample of 78 radio-loud and radio-quiet narrow-line Seyfert 1 (NLS1) galaxies, together with... -
Multifrequency study of NL Seyfert 1 galaxies
High-energy {gamma}-rays, which are produced by powerful relativistic jets, are usually associated with blazars and radio galaxies. In the current active galactic nuclei (AGN)... -
NGC6240 high resolution mapping of CO(1-0)
We present long baseline CO(1-0) mapping of the luminous infrared galaxy NGC 6240 obtained with the IRAM - Plateau de Bure Interferometer. This source is a well known... -
NGC253 near-infrared H_2_ emission
Because of its large angular size and proximity to the Milky Way, NGC 253, an archetypal starburst galaxy, provides an excellent laboratory to study the intricacies of this... -
Extended CO structures in NGC6240
We present deep CO(1-0) observations of NGC6240 performed with the IRAM Plateau de Bure Interferometer (PdBI). NGC6240 is the prototypical example of a major galaxy merger in...
