    Using SN 1987A as a cosmic laboratory, Miceli et al. have measured the shock acceleration of ions heavier than oxygen, finding that the post-shock temperature of a wide range of ions is mass dependent.

    ALMA observations of well-studied quadruple stellar system HD 98800 have revealed the presence of a circumbinary disk in a polar orientation around one of the binary pairs, providing observational confirmation of the theoretical stability of such an arrangement.

    Increased UV–optical nuclear emission in a nearby galaxy together with a spectrum showing emission lines typical of unobscured AGNs and Bowen fluorescence features suggests a longer-term event of intensified accretion onto the central supermassive black hole.

    Precise polarization measurements from the gamma-ray burst polarimeter POLAR suggest that the gamma-ray emission is at most polarized at a level lower than predicted by some models and also shows intrapulse evolution of its polarization angle.

    Examining and comparing many of the definitions of a black hole, it is concluded that the profusion of different definitions is a virtue that makes the investigation of black holes possible and fruitful in many different kinds of problems.

    KAGRA is a new gravitational wave detector being built in Japan. Unlike LIGO/Virgo, it will operate at cryogenic temperatures with sapphire mirrors. KAGRA will help improve the localization of gravitational wave detections and determination of the source parameters.

    The degree of polarization of gamma-ray bursts seems to be lower than previously thought. Gamma-ray polarimetry can reveal the emission mechanism and physical information inside the relativistic jet.

    The surface of Mars has been well mapped and characterized, yet the subsurface — the most likely place to find signs of extant or extinct life and a repository of useful resources for human exploration — remains unexplored. In the near future this is set to change.

    Intermediate-mass black holes (BHs) in local dwarf galaxies are considered the relics of the early seed BHs. However, their growth might have been impacted by galaxy mergers and BH feedback so that they cannot be treated as tracers of the early seed BH population.
