    Binary pulsars as probes of a Galactic dark matter disk 
    Caputo, Andrea; Zavala Franco, Jesus; Blas, Diego (Elsevier BV, 2018-03)
    As a binary pulsar moves through a wind of dark matter particles, the resulting dynamical friction modifies the binary’s orbit. We study this effect for the double disk dark matter (DDDM) scenario, where a fraction of the dark matter is dissipative ...

(American Astronomical Society, 2017-10-16)
    We report the discovery and monitoring of the near-infrared counterpart (AT2017gfo) of a binary neutron-star merger event detected as a gravitational wave source by Advanced Laser Interferometer Gravitational-wave Observatory (LIGO)/Virgo (GW170817) ...

(American Astronomical Society, 2017-10-16)
    We present Hubble Space Telescope (HST) and Chandra imaging, combined with Very Large Telescope MUSE integral field spectroscopy of the counterpart and host galaxy of the first binary neutron star merger detected via gravitational-wave emission by LIGO ...

    Non-analyticity of holographic Rényi entropy in Lovelock gravity 
    Giangreco Puletti, Valentina; Pourhasan, Razieh (Springer Nature, 2017-08)
    We compute holographic Rényi entropies for spherical entangling surfaces on the boundary while considering third order Lovelock gravity with negative cosmological constant in the bulk. Our study shows that third order Lovelock black holes with hyperbolic ...

    Space–charge limited current in nanodiodes: Ballistic, collisional, and dynamical effects 
    Zhang, Peng; ANG, YEE SIN; Garner, Allen; Valfells, Agust; Luginsland, John; ANG, LAY KEE (AIP Publishing, 2021-03-14)
    This Perspective reviews the fundamental physics of space–charge interactions that are important in various media: vacuum gap, air gap, liquids, and solids including quantum materials. It outlines the critical and recent developments since a previous ...

    Stellar orbits in adiabatically and impulsively evolving dark matter dominated potentials 
    Burger, Jan David (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2021)
    In the ΛCDM concordance model cold and collision-less dark matter (CDM) accounts for about four fifths of the Universe’s total matter content, while visible baryonic matter makes up the final fifth. The ΛCDM model successfully describes how large ...
