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…
