Bright lenses are easy to find: Spectroscopic confirmation of lensed quasars in the Southern Sky
C. Spiniello, A. Agnello, A. V. Sergeyev +4
Gravitationally lensed quasars are valuable, but extremely rare, probes of observational cosmology and extragalactic astrophysics. Progress in these fields has been limited just by…
Catalog of quasars from the Kilo-Degree Survey Data Release 3
S. Nakoneczny, M. Bilicki, A. Solarz +5
We present a catalog of quasars selected from broad-band photometric ugri data of the Kilo-Degree Survey Data Release 3 (KiDS DR3). The QSOs are identified by the random forest (RF…
KiDS0239-3211: A new gravitational quadruple lens candidate
A. Sergeyev, C. Spiniello, V. Khramtsov +5
We report the discovery of a candidate to quadrupole gravitationally lensed system KiDS0239-3211 based on the public data release 3 of the KiDS survey and machine learning techniqu…
The first sample of spectroscopically confirmed ultra-compact massive galaxies in the Kilo Degree Survey
C. Tortora, N. R. Napolitano, M. Spavone +25
We present results from an ongoing investigation using the Kilo Degree Survey (KiDS) on the VLT Survey Telescope (VST) to provide a census of ultra-compact massive galaxies (UCMGs)…
Quasar Lenses in the South: searches over the DES public footprint
Adriano Agnello, Chiara Spiniello
We have scanned 5000 deg of Southern Sky to search for strongly lensed quasars with five methods, all source-oriented, but based on different assumptions and selection criter…
KiDS-SQuaD: The KiDS Strongly lensed Quasar Detection project
C. Spiniello, A. Agnello, N. R. Napolitano +11
New methods have been recently developed to search for strong gravitational lenses, in particular lensed quasars, in wide-field imaging surveys. Here, we compare the performance of…
The Fornax Cluster VLT Spectroscopic Survey II - Planetary Nebulae kinematics within 200 kpc of the cluster core
C. Spiniello, N. R. Napolitano, M. Arnaboldi +10
We present the largest and most spatially extended planetary nebulae (PNe) catalog ever obtained for the Fornax cluster. We measured velocities of 1452 PNe out to 200 kpc in the cl…
The Fornax Cluster VLT Spectroscopic Survey. I - VIMOS spectroscopy of compact stellar systems in the Fornax core region
V. Pota, N. R. Napolitano, M. Hilker +21
We present the results of a wide spectroscopic survey aimed at detecting extragalactic globular clusters (GCs) in the core of the Fornax cluster. About 4500 low resolution spectra…
