    Collapsograms: measurement of low signal-to-noise-ratio solar p modes in spatially-resolved helioseismic data
    1.- I will give an overview of WeCAPP (Wendelstein Calar Alto Pixellensing Project), a microlensing survey towards the Andromeda galaxy. WeCAPP monitored the...

    Comparison of hydrostatic and lensing cluster mass estimates: A pilot study in MACS J0647.7+7015
    The detailed characterization of scaling laws relating the observables of a cluster of galaxies to their mass is crucial for obtaining accurate cosmological...

    Consistency of cosmic shear analyses in harmonic and real space
    Recent cosmic shear studies have reported discrepancies of up to 1σ on the parameter ${S_{8}=\sigma _{8}\sqrt{{\Omega _{\rm m}}/0.3}}$ between the analysis of...

    Consistent lensing and clustering in a low-S<SUB>8</SUB> Universe with BOSS, DES Year 3, HSC Year 1, and KiDS-1000
    We evaluate the consistency between lensing and clustering based on measurements from Baryon Oscillation Spectroscopic Survey combined with galaxy-galaxy...

    Constraining strong lensing models with dynamics
    Galaxy groups have an important role in the hierarchical assembly of structures in the Universe. Since galaxy groups are much more massive than galaxy-scale...

    Constraining the baryonic feedback with cosmic shear using the DES Year-3 small-scale measurements
    We use the small scales of the Dark Energy Survey (DES) Year-3 cosmic shear measurements, which are excluded from the DES Year-3 cosmological analysis, to...

    Constraining the inner density slope of massive galaxy clusters
    We determine the inner density profiles of massive galaxy clusters (M 200 > 5 × 10 14 M ☉) in the Cluster-EAGLE (C-EAGLE) hydrodynamic simulations, and...

    Constraints on Jupiters from observations of Galactic bulge microlensing events during 2000
    We present observations of eight Galactic bulge microlensing events taken with the 1.0-m Jacobus Kapteyn Telescope (JKT) on La Palma during 2000 June and July...

    Constraints on the Abundance of Primordial Black Holes from X-Ray Quasar Microlensing Observations: Substellar to Planetary Mass Range
    We use X-ray observations of quasar microlensing (sensitive to smaller compact objects than in the optical) to study the possible presence of a population of...
