AGN flares from ZTF DR23
Active galactic nuclei (AGNs) are known to exhibit stochastic variability across a wide range of timescales and wavelengths. AGN flares are extreme outbursts that deviate from... -
Optical variability of jetted AGN
The variability characteristics of jetted active galactic nuclei (AGNs) serve as a powerful diagnostic tool for probing the physical mechanisms underlying accretion processes... -
OzDES DR2 redshift catalogue
We present a description of the Australian Dark Energy Survey (OzDES) and summarize the results from its 6 years of operations. Using the 2dF fibre positioner and AAOmega... -
Changing-Look AGN from DESI. V.
We present a systematic search for changing-look (CL) quasars at high redshift z>0.9 by crossmatching the spectroscopic data sets from the Dark Energy Spectroscopic... -
The J-HERTz catalog from J-PLUS & LoTSS
We introduce J-HERTz (J-PLUS Heritage Exploration of Radio Targets at z<5), a new multiwavelength catalog that combines optical narrowband photometry from J-PLUS, infrared... -
Euclid accretion properties of X-ray AGN
The Euclid Quick Data Release (Q1) is a powerful dataset to study active galactic nuclei (AGN) and their host galaxies. Deriving their physical properties through... -
4FGL very high-energy gamma-ray emitting blazars
Very high-energy (VHE; >100GeV) {gamma}-ray emission originates via some of the most extreme particle acceleration processes in the Universe. Considering beamed active... -
G4Jy. Multiwavelength data and analysis
We provide an updated 'multiwavelength' version of the G4Jy catalogue (available at https://github.com/svw26/G4Jy, https://zenodo.org/communities/g4jy/records, and through... -
Star formation rates of SDSS z<0.3 galaxies
We utilize a large sample of ~113,000 galaxies (z<0.3) from the Sloan Digital Sky Survey with high-quality data to compare star formation rates (SFRs) across multiple... -
Properties of type 2 AGNs
To establish a more comprehensive understanding of the connection between galaxy mergers and active galactic nuclei (AGNs), it is essential to disentangle the contributions of... -
Properties and asymmetries of QSOs host galaxies
How does the host galaxy morphology influence a central quasar or vice versa? We address this question by measuring the asymmetries of 2424 SDSS quasar hosts at 0.2 < z <... -
LCOGT LCs of the variable AGN 6dFGS gJ022550.0-060145
We use LCOGT observations (MJD 59434-59600) with a total exposure time of ~50hr and a median cadence of 0.5d to measure the interband time delays (with respect to u) in the g,... -
NGC 5194, 4631, 5474 point sources from X-band VLA
We present 115 compact radio point sources in three galaxies, NGC 5474, NGC 4631, and M51, taken in the most extended (A-)configuration of the Karl G. Jansky Very Large Array at... -
Euclid spectroscopy of quasars. 1.
The slitless spectroscopy mode of the Near-Infrared Spectrometer and Photometer (NISP) on board the Euclid telescope has enabled efficient spectroscopy of objects within a large... -
The X-ray ExSeSS source sample from 2SXPS
We present the Extragalactic Serendipitous Swift Survey (ExSeSS), providing a new well-defined sample constructed from the observations performed using the Swift X-ray... -
HSC gLSB galaxies structures and SB properties
Rare giant low surface brightness galaxies (gLSBGs) act as a stress test for the current galaxy formation paradigm. To answer the question 'How rare are they?', we estimate... -
X-ray catalog and classification of 4FGL-DR4 UGSs
Our survey of the fourth Fermi Large Area Telescope catalog (4FGL) unassociated gamma-ray source regions using the X-Ray Telescope (XRT) and Ultraviolet/Optical Telescope (UVOT)... -
CEERS Key Paper. VIII. NIRSpec & NIRCam sp.
We use James Webb Space Telescope Near-Infrared Camera Wide Field Slitless Spectroscopy (NIRCam WFSS) and the Near-Infrared spectrograph (NIRSpec) in the Cosmic Evolution Early... -
Classifying intermediate-z galaxies in SDSS
We select a sample of 1437 active galactic nuclei (AGN) from the catalog of the Sloan Digital Sky Survey galaxy properties from the Portsmouth group by detection of the... -
AGN 8GHz measurements
Very long baseline interferometry (VLBI) measurements of the sizes of compact extragalactic radio sources, jetted active galactic nuclei, provide data for probing the angular...
