Description
We present results from the imaging of a sample of 12 interacting galaxies for which we have cataloged all potential dwarf systems in the vicinity of these strongly interacting galaxies. After careful cleaning of the images and applying a restrictive S/N criterion we have identified, measured and cataloged all possible extended objects in each field. On the frames, covering 11.4 x 10.5 arcmins, typically 100-200 non-stellar faint, extended objects were found. The vast majority (>98%) of these objects had not been previously identified. The number of expected objects in the magnitude range R= 18 - 19.5 exceeds the expected count of background galaxies. This supports the possibility that a density enhancement of extended objects around some interacting galaxies results from the addition of a locally formed dwarf galaxy population.

    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
