Braneworld black holes and black strings [PDF]

open access: yes, 2008
This thesis involves the study of strong and weak gravity phenomenology within the braneworld paradigm. We begin with a general overview of the hypothesised concept of extra spatial dimensions and explain why they are so interesting.

Upper limits on the temperature of inspiraling astrophysical black holes

open access: yes, 2021
We present a method to constrain the temperature of astrophysical black holes through detecting the inspiral phase of binary black hole coalescences.

Hypervelocity Stars Trace a Supermassive Black Hole in the Large Magellanic Cloud

open access: yesThe Astrophysical Journal
Hypervelocity stars (HVSs) are produced by the Hills mechanism when a stellar binary is disrupted by a supermassive black hole (SMBH). The HVS Survey detected 21 unbound B-type main-sequence stars in the Milky Way’s outer halo that are consistent with ...

Generalized Chemical Model for Warm Dense Hydrogen: Ionization Potential Depression and Molecular Dissociation Shifts

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Warm dense matter (WDM) is a complex state, where quantum effects, thermal excitations, and strong interparticle correlations coexist. Understanding its microscopic composition and medium‐induced modifications of atomic and molecular properties is essential for planetary modeling, fusion research, and high‐energy‐density experiments.

Braneworld black holes [PDF]

open access: yes, 2006
The braneworld paradigm provides an interesting framework within which to explore the possibility that our Universe lives in a fundamentally higher dimensional space- time.

Flexible Direct‐Conversion X‐Ray Detectors: From Emerging Materials to Conformal Imaging

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This comprehensive review analyzed the performance, challenges, and future directions of four emerging material systems for next‐generation flexible direct‐conversion X‐ray detectors: organic semiconductors, perovskites, metal–organic frameworks, and inorganic metal compounds.

High/low temperature setups for submillimetric samples under various extreme conditions at the AILES beamline

open access: yesJournal of Synchrotron Radiation, EarlyView.
Two complementary high‐ and low‐temperature experimental setups have been developed at the AILES beamline of Synchrotron SOLEIL to enable infrared and terahertz spectroscopy of submillimetric samples under extreme and well controlled pressure and temperature conditions (from 10 K to 600 K and from vacuum up to 100 GPa).

Further Evidence for a Direct-collapse Origin of the Supermassive Black Hole at the Center of the ∞ Galaxy

open access: yesThe Astrophysical Journal Letters
The z = 1.14 ∞ galaxy consists of two ringed nuclei with an active supermassive black hole (SMBH) in between them. The system is likely the result of a nearly face-on collision between two disk galaxies with massive bulges. In P. van Dokkum et al.

Approaching the Black Hole by Numerical Simulations

open access: yesUniverse, 2019
Black holes represent extreme conditions of physical laws. Predicted about a century ago, they are now accepted as astrophysical reality by most of the scientific community.

Vertical profiling of shock attenuation at the Rochechouart impact structure, France

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Rochechouart, south‐west France, is a complex impact structure. Here, we present the first report of shock barometry of quartz from what are likely parautochthonous basement units at depth, based on samples from the 2017 C.I.R.I.R drilling campaign. The crystallographic orientations of 725 sets of PDFs in 512 quartz grains in samples from four
