The Baryonic Mass–Halo Mass Relation of Extragalactic Systems
The Astrophysical JournalWe combine data for extragalactic systems to quantify a relation between the observed baryonic mass M _b and the enclosed dynamical mass M _200 inferred from kinematics or gravitational lensing.

The Scales of Gravitational Lensing
Universe, 2016 After exactly a century since the formulation of the general theory of relativity, the phenomenon of gravitational lensing is still an extremely powerful method for investigating in astrophysics and cosmology.

, 2017 Gravitational lensing is a consequence of general relativity, where the gravitational force due to a massive object bends the paths of light originating from distant objects lying behind it.

Physics Letters BIn this paper, we theoretically investigate gravitational lensing within the space-time framework of traversable wormholes, focusing on the combined effects of a global monopole and a cosmic string.

Generating Dark Matter Subhalo Populations Using Normalizing Flows
The Open Journal of AstrophysicsStrong gravitational lensing is a powerful tool for probing the nature of dark matter, as lensing signals are sensitive to the dark matter substructure within the lensing galaxy.

A Reidentification of Six Candidate Gravitationally Lensed Gamma-Ray Bursts
The Astrophysical JournalThe gravitational lensing effect of gamma-ray bursts (GRBs) holds significant and diverse applications in the field of astronomy. Nevertheless, the identification of millilensing events in GRBs presents substantial challenges.

, 2000 We review theory and applications of weak gravitational lensing. After summarising Friedmann-Lemaitre cosmological models, we present the formalism of gravitational lensing and light propagation in arbitrary space-times.

Gravitational lensing by black holes: The case of Sgr A*
, 2014 The strong gravitational fields created by black holes dramatically affect the propagation of photons by bending their trajectories. Gravitational lensing thus stands as the main source of information on the space-time structure in such extreme regimes ...

Cluster Lensing Mass Inversion (CLUMI+): Combining Dynamics and Weak Lensing around Galaxy Clusters
The Astrophysical JournalWe present clumi+ , a self-consistent, multiprobe methodology for reconstructing the mass distribution in and around galaxy clusters by combining gravitational lensing and dynamical observations. Building on the joint likelihood framework of K.
