Development of Intra‐Rift Basins During Stress Field Change in the Central Upper Rhine Graben (SW Germany)

open access: yesTectonics, Volume 44, Issue 4, April 2025.
Abstract The essentially non‐magmatic continental rift system of the Upper Rhine Graben (URG) is segmented and characterized by intra‐rift sub‐basins that exhibit NE to NW trends suggesting complex basin development during rifting. Structural modeling and analyses of an about 40 km2 3D seismic survey from the northern part of the central URG segment ...

Light bending and gravitational lensing in Brans-Dicke theory

open access: yesPhysics Letters B, 2019
As an important candidate theory of gravity, Brans-Dicke theory has been widely studied. In this paper, we investigate light bending and gravitational lensing by compact objects in Brans-Dicke theory in weak gravitational field.

Weak-lensing Characterization of the Dark Matter in 29 Merging Clusters that Exhibit Radio Relics

open access: yesThe Astrophysical Journal Supplement Series
We present a multiwavelength analysis of 29 merging galaxy clusters that exhibit radio relics. For each merging system, we perform a weak-lensing analysis on Subaru optical imaging.

Weak gravitational lensing of distant galaxies

open access: yesThe Astrophysical Journal, 1992
We analyze the two-point statistics of the gravitationally induced ellipticities of distant images whick provide a direct probe of the mass fluctuation spectrum P(k). The analysis extends previous work in the following respects : (1) We explore the relation between the ellipticity pattern of the background galaxies and the projected density of ...

For special purposes only: Ceramic casting moulds from the late Bronze and Early Iron Age metallurgical workshop in Grzybiany (SW Poland)

open access: yesArchaeometry, Volume 67, Issue 2, Page 482-501, April 2025.
Abstract Ceramic moulds are regarded as highly specialised, refractory tools used in metallurgy, yet their production process still needs clarification. Our research aimed to characterise the stages of operational chains applied in mould manufacture. The evidence comes from the Late Bronze and Early Iron Age lake settlement in Grzybiany in SW Poland ...

Tackling toxins: Case studies of industrial pollutants and implications for climate policy

open access: yesRegulation &Governance, Volume 19, Issue 2, Page 329-348, April 2025.
Abstract As scholars race to address the climate crisis, they have often treated the problem as sui generis and have only rarely sought to learn from prior efforts to make industrial operations greener. In this paper, we consider what can be learned from other shifts away from polluting substances.

Weak-lensing Analysis of the Complex Cluster Merger A746 with Subaru/Hyper Suprime-Cam

open access: yesThe Astrophysical Journal
The galaxy cluster A746 ( z = 0.214), featuring a double radio relic system, two isolated radio relics, a possible radio halo, disturbed V-shaped X-ray emission, and intricate galaxy distributions, is a unique and complex merging system.

The Measurement of the Splash-back Radius of Dark Matter Halos

open access: yesThe Astrophysical Journal
In the hierarchical evolution framework of cosmology, larger halos grow through matter accretion and halo mergers. To clarify halo evolution, we need to define the halo mass and radius physically.

SuperBIT Superpressure Flight Instrument Overview and Performance: Near-diffraction-limited Astronomical Imaging from the Stratosphere

open access: yesThe Astronomical Journal
SuperBIT was a 0.5 m near-UV to near-infrared wide-field telescope that launched on a NASA superpressure balloon into the stratosphere from New Zealand for a 45-night flight.

Indefinitely Flat Circular Velocities and the Baryonic Tully–Fisher Relation from Weak Lensing

open access: yesThe Astrophysical Journal Letters
We use a new deprojection formula to infer the gravitational potential around isolated galaxies from weak gravitational lensing. The results imply circular velocity curves that remain flat for hundreds of kiloparsecs, greatly extending the classic result
