Geology of the central uplift of the Kamestastin Lake impact structure, Labrador, Canada
Meteoritics &Planetary Science, EarlyView.Abstract The ~28 km Kamestastin (Mistastin) Lake impact structure is a relatively well‐preserved and well‐exposed complex impact structure. The central uplift of this structure is accessible as two islands in the middle of Kamestastin Lake. We present an updated, detailed geological map and description of Horseshoe and Bullseye islands that provides ...

Weak Gravitational Lensing and Cosmology [PDF]
, 2017 Albert Einstein’s General Theory of Relativity radically transformed our understanding of gravitation. Along with this transformative view came several powerful predictions.

CMB as a Probe of New Physics and Old Times [PDF]
, 2013 Cosmic birefringence (CB)---a rotation of photon-polarization plane in vacuum---is a generic signature of new scalar fields that could provide dark energy. Previously, WMAP observations excluded a uniform CB-rotation angle larger than a degree.

The Astrophysical JournalScaling relations between galaxy cluster properties are crucial for understanding cosmology and baryonic physics. Rigorous calibration of the M – L _X relation, employing weak lensing mass and consistent statistical methodology, is challenging due to ...

The Astrophysical JournalWe present a novel, model-independent technique for fitting the cross-component of weak lensing shear, γ _× , along a line of sight by combining kinematic and photometric measurements of a single lensed galaxy.

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.

Weak gravitational lensing with SKA
, 1999 I shall outline the basic principles and some observational aspects of weak gravitational lensing, and discuss several applications of this powerful tool in observational cosmology. It will be explained why the applications have been restricted to optical observations up to now, and why SKA is going to change this. I conclude with a few general remarks

Supervising Your In‐Group? How Social Identification Shapes Financial Sector Regulatory Leniency
Regulation &Governance, EarlyView.ABSTRACT Both practitioners and governance scholars recognize the importance of external oversight, especially in regulated industries like the financial sector. However, the failure of financial sector regulators and enforcement officials (supervisors) to act is often cited as a primary cause of ineffective governance.
