Cosmological Evolution of Semilocal String Networks
A. Achucarro, A. Avgoustidis, A. Lopez-Eiguren +2
Semilocal strings -- a particular limit of electroweak strings -- are an interesting example of a stable non-topological defect whose properties resemble those of their topological…
CCCP and MENeaCS: (updated) weak-lensing masses for 100 galaxy clusters
Ricardo Herbonnet, Cristóbal Sifón, Henk Hoekstra +7
Large area surveys have detected significant samples of galaxy clusters that can be used to constrain cosmological parameters, provided that the masses of the clusters are measured…
Exploiting flux ratio anomalies to probe warm dark matter in future large scale surveys
David Harvey, Wessel Valkenburg, Amelie Tamone +3
Flux ratio anomalies in strong gravitationally lensed quasars constitute a unique way to probe the abundance of non-luminous dark matter haloes, and hence the nature of dark matter…
Measuring the BAO peak position with different galaxy selections
César Hernández-Aguayo, Marius Cautun, Alex Smith +2
We investigate if, for a fixed number density of targets and redshift, there is an optimal way to select a galaxy sample in order to measure the baryon acoustic oscillation (BAO) s…
How to constrain warm dark matter with the Lyman forest
A. Garzilli, A. Magalich, O. Ruchayskiy +1
The flux power spectrum of the high resolution Lyman- forest data exhibits suppression at small scales. The origin of this suppression can be due to long-sought warm dark matter…
TDCOSMO. I. An exploration of systematic uncertainties in the inference of from time-delay cosmography
M. Millon, A. Galan, F. Courbin +22
Time-delay cosmography of lensed quasars has achieved 2.4% precision on the measurement of the Hubble constant, . As part of an ongoing effort to uncover and control systemati…
Phenomenology of the generalized cubic covariant Galileon model and cosmological bounds
Noemi Frusciante, Simone Peirone, Luis Atayde +1
We investigate the generalized cubic covariant Galileon model, a kinetically driven dark energy model within the Horndeski class of theories. The model extends the cubic covariant…
Euclid: The reduced shear approximation and magnification bias for Stage IV cosmic shear experiments
A. C. Deshpande, T. D. Kitching, V. F. Cardone +69
Stage IV weak lensing experiments will offer more than an order of magnitude leap in precision. We must therefore ensure that our analyses remain accurate in this new era. Accordin…
Iterative removal of redshift space distortions from galaxy clustering
Yuchan Wang, Baojiu Li, Marius Cautun
Observations of galaxy clustering are made in redshift space, which results in distortions to the underlying isotropic distribution of galaxies. These redshift-space distortions (R…
RELICS: A Very Large () Cluster Lens -- RXC J0032.1+1808
Ana Acebron, Adi Zitrin, Dan Coe +38
Extensive surveys with the \textit{Hubble Space Telescope} (HST) over the past decade, targeting some of the most massive clusters in the sky, have uncovered dozens of galaxy-clust…
The shape of relaxed galaxy clusters and the public release of a HST shape measurement code, pyRRG
David Harvey, Sut-Ieng Tam, Mathilde Jauzac +2
We study the shape of eight dynamically relaxed galaxy clusters observed with the Hubble Space Telescope and Chandra X-Ray Observatory. Using strong and weak gravitational lensing,…
Revived Fossil Plasma Sources in Galaxy Clusters
S. Mandal, H. T. Intema, R. J. van Weeren +10
It is well established that particle acceleration by shocks and turbulence in the intra-cluster medium can produce cluster-scale synchrotron emitting sources. However, the detailed…
On the inflationary massive field with a curved field manifold
Dong-Gang Wang
Massive fields during inflation provide an interesting opportunity to test new physics at very high energy scales. Meanwhile in fundamental realizations, the inflationary field spa…
The bias of dark matter tracers: assessing the accuracy of mapping techniques
M. Pellejero-Ibañez, A. Balaguera-Antolínez, Francisco-Shu Kitaura +7
We present a comparison between approximated methods for the construction of mock catalogs based on the halo-bias mapping technique. To this end, we use as reference a high resolut…
Hydrostatic mass estimates of massive galaxy clusters: a study with varying hydrodynamics flavours and non-thermal pressure support
Francesca A. Pearce, Scott T. Kay, David J. Barnes +2
We use a set of 45 simulated clusters with a wide mass range (M) to investigate the effect of varying hydrodynamics flavou…
A blinding solution for inference from astronomical data
Elena Sellentin
This paper presents a joint blinding and deblinding strategy for inference of physical laws from astronomical data. The strategy allows for up to three blinding stages, where the d…
Strong Lensing Time Delay Constraints on Dark Energy: a Forecast
Banafshe Shiralilou, Matteo Martinelli, Georgios Papadomanolakis +3
Measurements of time delays between multiple quasar images produced by strong lensing are reaching a sensitivity that makes them a promising cosmological probe. Future surveys will…
The effects of varying depth in cosmic shear surveys
Sven Heydenreich, Peter Schneider, Hendrik Hildebrandt +7
We present a semi-analytic model for the shear two-point correlation function of a cosmic shear survey with non-uniform depth. Ground-based surveys are subject to depth variations…
Cross-correlation of the astrophysical gravitational-wave background with galaxy clustering
Guadalupe Cañas-Herrera, Omar Contigiani, Valeri Vardanyan
We investigate the correlation between the distribution of galaxies and the predicted gravitational-wave background of astrophysical origin. We show that the large angular scale an…
