    Prospects for high-z cluster detections with Planck, based on a follow-up of 28 candidates using MegaCam at CFHT
    The Planck catalogue of SZ sources limits itself to a significance threshold of 4.5 to ensure a low contamination rate by false cluster candidates. This means...

    Pseudobulges in the Disk Galaxies NGC 7690 and NGC 4593
    We present Ks-band surface photometry of NGC 7690 (Hubble type Sab) and NGC 4593 (SBb). We find that, in both galaxies, a major part of the ``bulge'' is as flat...

    PSZ2 G282.28+49.94, a recently discovered analogue of the famous Bullet Cluster
    We present a detailed study of the gas and galaxy properties of the cluster PSZ2 G282.28+49.94 detected in the Planck all-sky survey. The intracluster medium...

    Pushing automated morphological classifications to their limits with the Dark Energy Survey
    We present morphological classifications of ~27 million galaxies from the Dark Energy Survey (DES) Data Release 1 (DR1) using a supervised deep learning...

    Puzzling large-scale polarization in the galaxy cluster Abell 523
    Large-scale magnetic fields reveal themselves through diffuse synchrotron sources observed in galaxy clusters such as radio halos. Total intensity filaments of...

    Pyroclastic Blowout: Dust Survival in Isolated versus Clustered Supernovae
    Following the current debate on the fate of SN-condensed dust grains, here we explore by means of three-dimensional hydrodynamical simulations the interaction...

    QSO size ratios from multiband monitoring of a microlensing high-magnification event
    We introduce a new scheme to study the nature of the central engine in a lensed QSO. The compact emission regions could have different sizes in different...
