Enhancing Photometric Redshift Catalogs Through Color-Space Analysis: Application to KiDS-Bright Galaxies
Priyanka Jalan, Maciej Bilicki, Wojciech A. Hellwing +11
We present a method to refine photometric redshift galaxy catalogs by comparing their color-space matching with overlapping spectroscopic calibration data. We focus on cases where…
A universal and physically motivated threshold for Hessian-based cosmic web identification: V-Web case
Edward Olex, Wojciech A. Hellwing, Alexander Knebe
The study of large-scale structure can benefit from accurate and robust identification of the cosmic web. Having such classification can facilitate a more complete extraction of co…
Extragalactic Stellar Tidal Streams: Observations meet Simulation
Juan Miro-Carretero, Maria A. Gomez-Flechoso, David Martinez-Delgado +11
According to the well established hierarchical framework for galaxy evolution, galaxies grow through mergers with other galaxies and the LambdaCDM cosmological model predicts that…
Bending the web: exploring the impact of modified gravity on the density field and halo properties within the cosmic web
Suhani Gupta, Simon Pfeifer, Punyakoti Ganeshaiah Veena +1
This work investigates the impact of different Modified Gravity (MG) models on the large-scale structures (LSS) properties in relation to the cosmic web (CW), using N-body simulati…
Improved analytical modeling of the non-linear power spectrum in modified gravity cosmologies
Suhani Gupta, Wojciech A. Hellwing, Maciej Bilicki
Reliable analytical modeling of the non-linear power spectrum (PS) of matter perturbations is among the chief pre-requisites for cosmological analyses from the largest sky surveys.…
Constraints on the properties of MSM dark matter using the satellite galaxies of the Milky Way
Oliver Newton, Mark R. Lovell, Carlos S. Frenk +4
Low-mass galaxies provide a powerful tool with which to investigate departures from the standard cosmological paradigm in models that suppress the abundance of small dark matter st…
