Foreground biases in strong gravitational lensing

Journal of Cosmology and Astroparticle Physics
Abstract Strong gravitational lensing is a competitive tool to probe the dark matter and energy content of the Universe. However, significant uncertainties can arise from the choice of lens model, and in particular the parameterisation of the line of sight.

Liberate or Subjugate Them? The Effect of Supplier Dependence on Buyer Innovation

Journal of Product Innovation Management, EarlyView.
ABSTRACT This study extends the current understanding of buyer–supplier relationships (BSRs) and innovation by investigating the supplier dependence—buyer innovation relationship. Drawing from resource dependence and exploration‐exploitation perspectives, we hypothesize that supplier dependence negatively affects buyer innovation performance, and that ...

Strong Gravitational Lensing with MeerKAT

Our view of the cosmic evolution of neutral hydrogen and the hydroxyl molecule in galaxies is being transformed through deep surveys with SKA precursors/pathfinders.  Strong gravitational lensing can enable a deeper tier to the ongoing and planned spectral line surveys, without some of the associated calibration risks posed by several thousand-hour ...

Innovation and Structural Design in Regionalized Supply Networks

Journal of Supply Chain Management, EarlyView.
ABSTRACT Regionalization is reshaping global supply networks (SNs) as firms respond to geopolitical, economic, and institutional pressures. Yet extant research has not examined how patterns of structural adaptation associated with regionalization may influence innovation. In this paper, we develop a typology of three theoretically grounded archetypes: (

Model-independent H0 within FLRW: Joint Constraints from GWTC-3 Standard Sirens and Strong Lensing Time Delays

The Astrophysical Journal Letters
We use 47 gravitational-wave (GW) standard sirens from the third Gravitational-Wave Transient Catalog to calibrate distances in the strong gravitational lensing (SGL) system RXJ1131-1231 and constrain the Hubble constant ( H _0 ) via the distance sum ...

Confirmation of the impact origin of the Late Ordovician Tvären impact structure (southeast Sweden) and emplacement of impactites in a marine setting

Meteoritics &Planetary Science, EarlyView.
Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

The First Model-independent Upper Bound on Microlensing Signature of the Highest-mass Binary Black Hole Event GW231123

The Astrophysical Journal
The recently discovered gravitational-wave event GW231123 is the most massive binary black hole merger detected to date. The inferred source masses of the event fall within the pair-instability supernova mass gap, where black holes formed directly from ...

Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

Meteoritics &Planetary Science, EarlyView.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

Gravitational lensing by a dark compact object in modified gravity and observational constraints from Einstein rings

European Physical Journal C: Particles and Fields
In this manuscript, we provide a comprehensive study of gravitational lensing by dark compact objects predicted by modified gravity (MOG) based on the scalar–vector–tensor action, with the aim of providing new insights into the nature of gravitational ...

Business Participation in Regulation: A Multifocal Perspective on Management Studies

Regulation &Governance, EarlyView.
ABSTRACT This paper conceptualizes how regulation is viewed in management studies in the context of business participation in regulation and explores its implications. We theorize six lenses through which management studies understand regulation: as competitive advantages, boundaries, forums, principles, systems, and cognitive frames.
