The imprint of $f(R)$ gravity on weak gravitational lensing I: Connection between observables and large scale structure

, 2016
We study the effect of $f(R)$ gravity on the statistical properties of various large-scale structures which can be probed in weak gravitational lensing measurements.

Ellipticities of Galaxy Cluster Halos from Halo–Shear–Shear Correlations

The Astrophysical Journal
We report the first detection of the halo ellipticities of galaxy clusters by applying the halo–shear–shear correlations (HSSCs), without the necessity of using major axis determination.

A Three‐Stage Model of the Maturation of Nascent Policy Subsystems Toward Stable Advocacy Coalitions, With Evidence From the UK's Response to COVID‐19

Policy Studies Journal, EarlyView.
ABSTRACT Policy subsystems are comprised of competing advocacy coalitions, in which public and private political actors with shared belief systems learn from each other and coordinate their strategies in the pursuit of influencing policy making in their favor.

Testing gravitational physics by combining DESI DR1 and weak lensing datasets using the E_G estimator

The Open Journal of Astrophysics
The action of gravitational physics across space-time creates observable signatures in the behaviour of light and matter. We perform combined-probe studies using data from the Baryon Oscillation Spectroscopic Survey (BOSS) and Dark Energy Spectroscopic ...

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 cross-correlations

, 2017
The matter content of the Universe is dominated by dark matter. Beyond its abundance and its lack of non-gravitational interactions with standard model matter, little is known about the nature of dark matter. This thesis attempts to illuminate different aspects of dark matter by using gravitational lensing in conjunction with other cosmological probes.

Soft‐bedded ice sheet in hummocky terrain of north‐central Poland: Origin of rim ridges and subglacial processes

Sedimentology, EarlyView.
ABSTRACT Hummocky terrains are characterised by various geomorphological features that typically record processes associated with the downwasting of ice sheets. Common landforms in these areas include ramparts, linear ridges, kettle holes and ice‐walled lake plains.
