Descripción
Two sources selected from the IRAS Point Source Catalogue (PSC) have been spectroscopically identified as galaxies with a Seyfert type active nucleus. The brightest of the first source, IRAS 20210 + 1121, is in close interaction with a companion galaxy at a projected distance of 1.1 kpc and has a perturbed spiral-like morphology. This galaxy presents some features which make it a candidate for an obscured Seyfert type 1. The second source, IRAS 01475 - 0740, has an elliptical morphology and might be located at the center of a group of galaxies.

    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

    Neural calibration of imaging Stokes polarimeters
    Current polarimetric calibration techniques derive the instrument modulation matrix by numerically fitting an instrumental model to measurements of a set of calibration Stokes vectors. These techniques are typically limited to an error on the retrieved normalized Stokes Q, U and V parameters, in the $1\times10^{-2}$ to $1\times10^{-3}$ range. This

    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
