Descripción
The morphological characteristics of corrugations in the disk shapes of the edge-on galaxies NGC 4244 and 5023 are described to determine some of the properties of these features. The corrugations are found to have a 'central' area of high corrugation and wavelike structures of increasing wavelengths emanating from the 'central' zone. If warps have extragalactic sources, they can originate corrugations which propagate inwards toward the central zone, but the cause of the initial perturbation is not determined.

    An ultra-short-period super-Earth with an extremely high density and an outer companion
    We present the discovery and characterization of a new multi-planetary system around the Sun-like star K2-360 (EPIC 201595106). K2-360 was first identified in K2 photometry as the host of an ultra-short-period (USP) planet candidate with a period of 0.88 d. We obtained follow-up transit photometry, confirming the star as the host of the signal

    Counting stars from the integrated spectra of galaxies
    Over the last few decades, evolutionary population synthesis models have powered an unmatched leap forward in our understanding of galaxies. From dating the age of the first galaxies in the Universe to providing detailed measurements of the chemical composition of nearby galaxies, the success of this approach built upon simple stellar population

    Model-based identification of solar coronal mass ejections using deep neural networks
    Coronal mass ejections (CMEs) are a major driver of space weather and thus can have important negative technological and social impacts. To assess their geoeffectiveness once they are ejected, it is crucial their prompt identification in coronagraph images. In the last decade, deep neural networks (DNN) have experienced enormous improvements in
