The CMB lensing signal from cosmic voids and superclusters probes the growth of structure in the low-redshift cosmic web. In this analysis, we cross-correlated the Planck CMB lensing map with voids detected in the Dark Energy Survey Year 3 (Y3) data set (~5000 deg 2), expanding on previous measurements that used Y1 catalogues (~1300 deg 2). Given

We present cosmological constraints from the analysis of angular power spectra of cosmic shear maps based on data from the first three years of observations by the Dark Energy Survey (DES Y3). Our measurements are based on the pseudo-C ℓ method and complement the analysis of the two-point correlation functions in real space, as the two estimators

Elements with weak and blended spectral features in stellar spectra are challenging to measure and require specialized analysis methods to precisely measure their chemical abundances. In this work, we have created a catalog of approximately 120,000 giants with high signal-to-noise Apache Point Observatory Galactic Evolution Experiment (APOGEE) Data

SummaryIn this work we present the design of the ATLAS (Asteroid Terrestrial-impact Last Alert System) unit that will be installed at Teide Observatory in Tenerife island (Spain). ATLAS-Teide will be built by the IAC and will operated as part of the ATLAS network in the framework of an operation and science exploitation agreement between the IAC

Context. Double-lined eclipsing binaries allow the direct determination of masses and radii, which are key for testing stellar models. With the launch of the TESS mission, many well-known eclipsing binaries have been observed at higher photometric precision, permitting the improvement of the absolute dimension determinations. Aims: Using TESS data
