    Limiting the Abundance of LIGO/Virgo Black Holes with Microlensing Observations of Quasars of Finite Size
    We present a simple but general argument that strongly limits the abundance of primordial black holes (PBHs) (or other unknown population of compact objects)...

    Limits on the Mass and Abundance of Primordial Black Holes from Quasar Gravitational Microlensing
    The idea that dark matter can be made of intermediate-mass primordial black holes (PBHs) in the 10 M ⊙ ≲ M ≲ 200 M ⊙ range has recently been reconsidered...

    LiteBIRD science goals and forecasts: a full-sky measurement of gravitational lensing of the CMB
    We explore the capability of measuring lensing signals in LiteBIRD full-sky polarization maps. With a 30 arcmin beam width and an impressively low polarization...

    LiteBIRD science goals and forecasts: improved full-sky reconstruction of the gravitational lensing potential through the combination of Planck and LiteBIRD data
    Cosmic microwave background (CMB) photons are deflected by large-scale structure through gravitational lensing. This secondary effect introduces higher-order...

    Long-term Monitoring, Time Delay, and Microlensing in the Gravitational Lens System Q0142-100
    We present 12 yr of monitoring of the gravitational lens Q0142-100 from the Teide Observatory. The data, taken from 1999 to 2010, comprise 105 observing nights...

    MAGIC detection of sub-TEV emission from gravitationally lensed blazar QSO B0218+357
    The blazar QSO B0218+357 is the first gravitationally lensed blazar detected in the very high energy (VHE, E > 100 GeV) gamma-ray spectral range (Ahnen et al...

    Mass calibration of DES Year-3 clusters via SPT-3G CMB cluster lensing
    We measure the stacked lensing signal in the direction of galaxy clusters in the Dark Energy Survey Year 3 (DES Y3) redMaPPer sample, using cosmic microwave...
