Quasar photometric redshifts beyond the spectroscopic coverage: Uncertainty models and redshift distributions in the Kilo-Degree Survey DR5
Kacper Drabicki, Szymon J. Nakoneczny, Maciej Bilicki
Photometric redshifts (photo-) and their distributions underpin cosmology with photometric quasars, tracers in angular clustering and cross-correlations. Progress requires trust…
The LOFAR Two-metre Sky Survey: VII. Third Data Release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +99
We present the third data release of the LOFAR Two-metre Sky Survey (LoTSS-DR3). The survey images cover 88% of the northern sky and were created from 12,950 hrs of data (18.6 PB)…
QZO: A Catalog of 5 Million Quasars from the Zwicky Transient Facility
S. J. Nakoneczny, M. J. Graham, D. Stern +11
Machine learning methods are well established in the classification of quasars (QSOs). However, the advent of light curve observations adds a great amount of complexity to the prob…
Cosmology from LOFAR Two-metre Sky Survey Data Release 2: Cross-correlations with luminous red galaxies from eBOSS
Jinglan Zheng, Prabhakar Tiwari, Gong-Bo Zhao +7
We cross-correlated galaxies from the LOw-Frequency ARray (LOFAR) Two-metre Sky Survey (LoTSS) second data release (DR2) radio source with the extended Baryon Oscillation Spectrosc…
The fifth data release of the Kilo Degree Survey: Multi-epoch optical/NIR imaging covering wide and legacy-calibration fields
Angus H. Wright, Konrad Kuijken, Hendrik Hildebrandt +51
We present the final data release of the Kilo-Degree Survey (KiDS-DR5), a public European Southern Observatory (ESO) wide-field imaging survey optimised for weak gravitational lens…
