Recent cosmic shear studies have shown that higher-order statistics (HOS) developed by independent teams now outperform standard two-point estimators in terms of statistical precision thanks to their sensitivity to the non-Gaussian features of large-scale structure. The aim of the Higher-Order Weak Lensing Statistics (HOWLS) project is to assess

Material outgassing in a vacuum leads to molecular contamination, a well-known problem in spaceflight. Water is the most common contaminant in cryogenic spacecraft, altering numerous properties of optical systems. Too much ice means that Euclid's calibration requirements cannot be met anymore. Euclid must then be thermally decontaminated, which is

Supermassive black holes (SMBHs) and nuclear star clusters (NSCs) co-exist in many galaxies. While the formation history of the black hole is essentially lost, NSCs preserve their evolutionary history imprinted onto their stellar populations and kinematics. Studying SMBHs and NSCs in tandem might help us to ultimately reveal the build-up of galaxy

Context. Dwarf elliptical galaxies (dEs) are the most abundant in the Universe. Research into these objects in connection with late-type dwarf galaxies is important for evaluating theories of dwarf galaxy formation and evolution. Aims: Our past studies (2000-2010) suggested a possible evolutionary link between early- and late-type dwarf galaxies

We present the new design of the ATLAS unit (Asteroid Terrestrial-impact Last Alert System (see [1]) to be installed at Teide Observatory (TO) in Tenerife island (Spain), and the results of the ongoing tests of the first module (ATLAS-P). ATLAS-Teide, the 5th ATLAS unit, will be built by the IAC and will be operated as part of the ATLAS network in

Context. Small planets located at the lower mode of the bimodal radius distribution are generally assumed to be composed of iron and silicates in a proportion similar to that of the Earth. However, recent discoveries are revealing a new group of low-density planets that are inconsistent with that description. Aims: We intend to confirm and
