eFEDS counterparts to point-like sources
Of the eROSITA/eFEDS sources (Brunner et al., 2022A&A...661A...1B, Cat. J/A+A/661/A1, Paper I), 24774 of 27369 have reliable counterparts (90.5%) in the main sample and 231... -
3C 84 multifrequency radio hybrid images
Due to its brightness and proximity, the radio galaxy 3C 84 (optical counterpart: NGC 1275 in the Perseus cluster) has been the target for extensive studies to investigate the... -
The Fermi LAT sky as seen by INTEGRAL/IBIS
In this Letter we present the result of the cross correlation between the fourth INTEGRAL/IBIS soft gamma-ray catalog, in the range 20-100keV, and the Fermi LAT bright source... -
MOJAVE VII. Blazar jet acceleration
We discuss acceleration measurements for a large sample of extragalactic radio jets from the Monitoring Of Jets in Active Galactic Nuclei with VLBA Experiments (MOJAVE) program,... -
Confirmed AGN type 1 & 2 from sp. in Kepler fields
We utilized the Edelson & Malkan (2012, J/ApJ/751/52) and Stern+ 2012ApJ...753...30S selection techniques and other methods to identify active galactic nuclei (AGN)... -
LBT-MODS long-slit opt. sp. of SDSS-FIRST galaxies
We present a study investigating the influence of jets on galaxies exhibiting strong [OIII]{lambda}5007 emission, known as Green Peas and Green Beans. Our sample comprised 12... -
VLBI-based combined catalog of radio sources
The International Celestial Reference System (ICRS) is realized in the radio band by a catalog of radio source positions obtained by very long baseline interferometry (VLBI)... -
3C 84 jet images
The location of gamma-ray creation and emission within extra-galactic jets is a matter of active debate. One particularly well-suited source to pinpoint the location is the... -
0446+11 15GHz VLBA images in Stokes I, Q, U
The physical mechanisms driving neutrino and electromagnetic flares in blazars remain poorly understood. We investigate a prominent multimessenger flare in the quasar PKS... -
Swift-BAT 150-month hard X-ray catalog ctps
We present a comprehensive catalog of 251 potential counterparts for 250 unassociated hard X-ray sources detected in the Swift- Burst Alert Telescope (BAT) 150-month hard X-ray... -
IceCube neutrinos-CAZ blazar light curves assoc.
The IceCube Neutrino Observatory has detected several hundred high-energy neutrinos from cosmic sources. Despite numerous studies searching for their origin, it is still not... -
7918 blazar-selected AGN CAZ catalog and LC
Active Galactic Nuclei (AGN) are some of the brightest and most variable objects in the universe. Those with relativistic jets observed at small viewing angles are blazars. Due... -
ZTF LC analysis of Fermi LAT (4LAC-DR3) AGNs
The variability mechanisms from jetted active galactic nuclei (AGNs) are still under debate. Here, the damped random walk (DRW) model, implemented through Gaussian processes... -
Supermassive BH with accretion rates in AGN. XIV.
We report the results of a long-duration high-cadence reverberation mapping campaign of a second batch of 11 PG quasars using the 2.2m telescope at the Calar Alto Observatory.... -
Kilioparsec morphology OIII catalog
Active Galactic Nuclei (AGN) outflows can regulate host galaxy evolution via AGN feedback. Ionised gas outflows have been linked to enhanced radio emission. In the first paper... -
SEAMBH in AGNs. XIII. Mrk142 GMOS and LJT spectra
We performed a rigorous reverberation-mapping analysis of the broad-line region (BLR) in a highly accreting (L/L_Edd_=0.74-3.4) active galactic nucleus, Markarian 142 (Mrk 142),... -
SEAMBHs XII. Reberberation mapping for 15 PG QSOs
In this work, we present the first results of the long-term high-cadence spectroscopic monitoring of 15 PG quasars with relatively strong FeII emission, as a part of a broader... -
SEAMBHs. XI. Mrk 142 X-ray to optical light curves
We performed an intensive accretion disk reverberation mapping campaign on the high accretion rate active galactic nucleus Mrk142 in early 2019. Mrk 142 was monitored with the...
