Summary: In this study, cross-correlation between galaxy weak lensing data and CMB lensing data was measured, yielding cosmological constraints consistent with flat ΛCDM cosmological models. The analysis demonstrated the potential of CMB weak lensing cross-correlations in setting constraints on redshift or shear calibration, particularly for challenging high-redshift galaxy samples.

Summary: The aim of this work is to investigate the origin of the large clustering signal detected in the TGSS radio survey and to study the properties of the radio sources in the frequency range of [0.15, 1.4] GHz. The analysis involved cross-correlating the positions of the radio sources with cosmic microwave background (CMB) lensing maps from the Planck satellite, and the results suggest that the excess signal found in the TGSS survey may be due to uncorrected systematic effects. The study also explores different models for the redshift distribution and bias evolution of the radio sources, finding that none of them fully explain the measured cross-spectrum at large angular scales.

Summary: Using luminous red galaxies selected from imaging surveys for targeting by the Dark Energy Spectroscopic Instrument (DESI) in combination with CMB lensing maps from the Planck collaboration, researchers probed the amplitude of large-scale structure over 0.4 <= z <= 1. Their findings suggest a slower growth of structure at low redshift than model predictions, with only modest significance.

Summary: This study investigates the cosmological constraints that can be obtained from the cross-correlation measurement of cosmic voids identified in the Euclid spectroscopic survey. The study finds that Euclid voids can accurately constrain the ratio of the transverse comoving distance and Hubble distance, as well as the growth rate, with high precision. Moreover, voids alone can provide precise measurements of the matter density parameter and the dark energy equation of state.

Summary: We propose a formalism for jointly fitting pre-and post-reconstruction redshift-space clustering, baryon acoustic oscillations, and gravitational lensing. We analyze clustering measured by the Baryon Oscillation Spectroscopic Survey in combination with CMB lensing measured by Planck. The results provide valuable constraints on various cosmological parameters.

Summary: Cosmic voids are powerful probes of cosmology, especially in studying the nature of gravity and the neutrino mass. Recent studies have shown that measurements of void imprint on the lensed Cosmic Microwave Background (CMB) are in tension with expectations based on simulations, suggesting the possibility of non-standard cosmological signatures due to massive neutrinos. This study uses cosmological simulations with massive neutrino cosmologies to investigate the impact of neutrinos on void properties observed in photometric surveys and the void-CMB lensing cross-correlation. The results provide insights into the potential role of massive neutrinos in explaining the tension observed and propose a new quantity for distinguishing different neutrino masses through future observations.

Summary: In this study, we investigate the use of three correlation functions - cluster lensing, the cluster-galaxy cross-correlation function, and the galaxy autocorrelation function - to self-calibrate optical cluster selection bias in a richness-selected sample. We develop mock catalogues of redMaGiC-like galaxies and redMaPPer-like clusters using N-body simulations and counts-in-cylinders around massive haloes as a richness proxy. We find that projection effects significantly boost both the projected and three-dimensional correlation functions. Likelihood analysis shows that the selection bias can be constrained at the 10 per cent level.

Summary: This study examines the impact of fiber assignment on galaxy clustering and its cross correlation with weak lensing fields. The results show that fiber assignment not only suppresses the amplitude of the galaxy power spectrum, but also introduces artificial correlation of structure at different redshifts, leading to a decrease in the amplitude of the galaxy-lensing cross power spectrum. However, by adjusting the observed galaxy probabilities, the effects of fiber assignment on the cross power spectrum can be mitigated to an accuracy of approximately 1%, while the galaxy power spectrum cannot be fully corrected.

Summary: This study examines the impact of fiber assignment on galaxy clustering measurements and its cross correlation with weak lensing fields. It is found that fiber assignment not only suppresses the amplitude of the galaxy power spectrum, but also introduces artificial correlation of structures at different redshifts, thereby suppressing the amplitude of the galaxy-lensing cross power spectrum. The effects of fiber assignment on the cross power spectrum can be mitigated by assigning observed galaxies with a probability to be observed, while the correction for the galaxy power spectrum remains challenging.

Summary: In this study, we propose an estimator for the lensing potential using galaxy number counts, which includes a linear and a quadratic term. Our results demonstrate that this estimator has a significantly higher signal-to-noise ratio compared to the corresponding estimator from intensity mapping. The improved signal-to-noise ratio is attributed to the additional lensing term in the number count angular power spectrum, which appears at linear order. We estimate the signal-to-noise ratio for future photometric surveys and find that it can reach an order of magnitude of 30, particularly at high redshifts (z greater than or similar to 1.5). Therefore, we argue that number counts in photometric surveys are an excellent tool for measuring tomographic lensing spectra.

Summary: Using data from 2014 and 2015 seasons of observation with the ACT, cosmic microwave background lensing mass maps were constructed and a novel cleaning procedure was used to remove thermal SZ contamination. The cross-spectrum between the cleaned lensing map and the BOSS CMASS galaxy sample was detected at 10 sigma significance. These results lay the foundation for future lensing cross-correlation science with ACT data.

Summary: Galaxy-galaxy lensing is an important tool for studying the connection between galaxies and dark matter haloes. This study extends the measurement and modelling of this lensing signal to highly non-linear scales, finding that galaxies typically reside in dark matter haloes of roughly constant mass. By constraining these halo properties, our understanding of galaxy evolution and cosmology can be improved.
