First detection of the GI-type of intrinsic alignments of galaxies using the self-calibration method in a photometric galaxy survey
Eske M. Pedersen, Ji Yao, Mustapha Ishak +1
Weak gravitational lensing is one of the most promising cosmological probes to constrain dark matter, dark energy, and the nature of gravity at cosmic scales. Intrinsic alignments…
Separating the Intrinsic Alignment Signal and the Lensing Signal using Self-Calibration in Photo-z Surveys with KiDS450 and KV450 Data
Ji Yao, Eske M. Pedersen, Mustapha Ishak +4
To reach the full potential for the next generation of weak lensing surveys, it is necessary to mitigate the contamination of intrinsic alignments (IA) of galaxies in the observed…
Cosmological discordances III: more on measure properties, Large-Scale-Structure constraints, the Hubble constant and Planck
Cristhian Garcia-Quintero, Mustapha Ishak, Logan Fox +1
Consistency between cosmological data sets is essential for ongoing and future cosmological analyses. We first investigate the questions of stability and applicability of some mome…
A Bayesian interpretation of inconsistency measures in cosmology
Weikang Lin, Mustapha Ishak
Measures of discordance between datasets have become an essential part of cosmological analyses. It is important to accurately evaluate the significance of such discordances when p…
ISiTGR: Testing deviations from GR at cosmological scales including dynamical dark energy, massive neutrinos, functional or binned parametrizations, and spatial curvature
Cristhian Garcia-Quintero, Mustapha Ishak, Logan Fox +1
We introduce a new version of the Integrated Software in Testing General Relativity (ISiTGR) which is a patch to the software CAMB and CosmoMC. ISiTGR is intended to test deviation…
The impact of baryonic physics and massive neutrinos on weak lensing peak statistics
Matthew Fong, Miyoung Choi, Victoria Catlett +5
We study the impact of baryonic processes and massive neutrinos on weak lensing peak statistics that can be used to constrain cosmological parameters. We use the BAHAMAS suite of c…
