Angular clustering and bias of photometric quasars in the Kilo-Degree Survey Data Release 4
Anjitha John William, Maciej Bilicki, Wojciech A. Hellwing +2
We investigate the angular clustering and effective bias of photometrically selected quasars in the Kilo-Degree Survey Data Release 4 (KiDS DR4). We update the previous photometric…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Hybrid-z: Enhancing Kilo-Degree Survey bright galaxy sample photometric redshifts with deep learning
Anjitha John William, Priyanka Jalan, Maciej Bilicki +3
We employ deep learning (DL) to improve photometric redshifts (photo-s) in the Kilo-Degree Survey Data Release 4 Bright galaxy sample (KiDS-Bright DR4). This dataset, used as a…
Caught in the cosmic web: environmental effects on subhalo abundance and internal density profiles
Feven Markos Hunde, Oliver Newton, Wojciech A. Hellwing +2
Using the high-resolution -body cosmological simulation COLOR, we explore the cosmic web (CW) environmental effects on subhalo populations and their internal properties. We use…
Simulations of the accreted stellar halos of low-mass field galaxies
Andrew P. Cooper, Carlos S. Frenk, Wojciech A. Hellwing +1
We predict the properties of stellar halos in galaxies of present-day virial mass by combining the GALFORM semi-analytic model of galaxy fo…
Target Selection for the Redshift-Limited WAVES-Wide with Machine Learning
Gursharanjit Kaur, Maciej Bilicki, Wojciech Hellwing +1
The forthcoming Wide Area Vista Extragalactic Survey (WAVES) on the 4-metre Multi-Object Spectroscopic Telescope (4MOST) has a key science goal of probing the halo mass function to…
