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... -
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... -
DESI observations of the Andromeda galaxy
We present Dark Energy Spectroscopic Instrument (DESI) observations of the inner halo of M31, which reveal the kinematics of a recent merger-a galactic immigration event-in... -
CIGALE intermediate redshifts Type II QSOs cand.
Active galactic nuclei (AGNs) play a vital role in the evolution of galaxies over cosmic time, significantly influencing their star formation and growth. As obscured AGNs are... -
The gamma/optical flares of 4FGL-DR3 blazars
Using blazar light curves from the optical All-Sky Automated Survey for Supernovae (ASAS-SN) and the {gamma}-ray Fermi-LAT telescope, we performed the most extensive statistical... -
~100 Gravitationally confirmed lensed quasars
We report the spectroscopic follow-up of 175 lensed quasar candidates selected using Gaia Data Release 2 observations following Paper III of this series. Systems include 86... -
SOUX AGN sample with SDSS-XMM-Newton surveys
We assemble a sample of 696 type 1 active galactic nuclei (AGN) up to a redshift of z = 2.5, all of which have an SDSS spectrum containing at least one broad emission line... -
Radio sources at 6~>z~>4 with ASKAP in G23
Using the Lyman Dropout technique, we identify 148 candidate radio sources at z ~> 4-7 from the 887.5 MHz Australian Square Kilometre Array Pathfinder (ASKAP) observations of... -
Gaia Focused Product Release (Gaia FPR)
The Gaia Focused Product Release builds partly on the data period that went into Gaia's Data Release 3 but in case of the Solar System objects extends the stretch of time that... -
Gaia DR3 Part 2. Extra-galactic
Gaia Data Release 3 (Gaia DR3) will be released on 13 June 2022. The Gaia DR3 catalogue builds upon the Early Data Release 3 (released on 3 December 2020) and combines, for the... -
Quasars from DESI SV data in the COSMOS/HSC fields
We present the first result in exploring the gaseous halo and galaxy correlation using the Dark Energy Spectroscopic Instrument survey validation data in the Cosmic Evolution... -
NIKA2 PCCS2 catalog
The Planck Catalogue of Compact Sources (PCCS2) is an unbiased census of the millimetre sky at sub-Jansky levels, and thus a valuable resource for studies of galaxy evolution.... -
AGN optical-infrared relation
Although the population of quasars evolved significantly in the past, the properties of quasars as physical objects are supposed to remain almost unchanged, which makes quasars... -
Redshift and reddening of 125 QSOs behind M31
Our aim is to increase the limited number of quasars behind M 31, necessary for probing the chemical content of the gas and for proper motion reference, with reliable and... -
Morpho-phot. classification of KiDS DR5 sources
We present a novel multimodal neural network (MNN) for classifying astronomical sources in multiband ground-based observations, from optical to near-infrared (NIR), to separate... -
New quasars Ca II absorbers with SDSS spectra
We report discoveries of 165 new quasar Ca II absorbers from the Sloan Digital Sky Survey (SDSS) Data Releases 7 and 12. Our CA II rest-frame equivalent width distribution... -
Spectra of lensed QSOs (SSAP)
An archive of optical and near-infrared spectra of strongly lensed quasars and the lensing galaxies. The spectra are resolved to about a few Ångstroms and are flux-calibrated....
