Structural and functional insights into extreme thermal stability and activity of two GH12 domains of a multidomain glycosidase from a hyperthermophilic euryarchaeon

open access: yesThe FEBS Journal, Volume 292, Issue 14, Page 3771-3794, July 2025.
The multidomain glycosidase MDG from the hyperthermophilic euryarchaeon Thermococcus sp. contains five protein domains: three catalytic domains (GH5, GH12‐1, and GH12‐2) and two cellulose‐binding modules (CBM2). In this study, the GH12‐1 and GH12‐2 domains were individually purified and biochemically characterized.

The Baryon Catastrophe and the multiphase intracluster medium [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1996
We review the theories and observations which together have led to the concept of the Baryon Catastrophe: observations of the baryon fraction on the scale of clusters of galaxies appear to be at least three times as high as the universal baryon fraction predicted by the theory of primordial nucleosynthesis in a flat, $ _0 = 1$, universe.

PROTOCOL: Effectiveness of Educational Programmes to Prevent and Counter Online Violent Extremist Propaganda in English, French, Spanish, Portuguese, German and Scandinavian Language Studies: A Systematic Review

open access: yesCampbell Systematic Reviews, Volume 21, Issue 2, June 2025.
ABSTRACT This protocol outlines a systematic review that aims to understand the effectiveness of educational programmes, delivered both online and offline, designed to prevent and counter the effects of online violent extremist propaganda in multiple languages. The primary objective is to assess the impact of interventions on reducing violent extremist

The Cosmic Large-Scale Structure in X-rays (CLASSIX) Cluster Survey I: Probing galaxy cluster magnetic fields with line of sight rotation measures

open access: yes, 2016
To search for a signature of an intracluster magnetic field, we compare measurements of Faraday rotation of polarised extragalactic radio sources in the line of sight of galaxy clusters with those outside.

Simulating the Arrival of the Southern Substructure in the Galaxy Cluster Abell 1758

open access: yesThe Astrophysical Journal
Abell 1758 ( z ∼ 0.278) is a galaxy cluster composed of two structures, A1758N and A1758S, separated by ∼2.2 Mpc. The northern cluster is itself a dissociative merging cluster that has already been modeled by dedicated simulations.

Testing the Collisionless Nature of Dark Matter with the Radial Acceleration Relation in Galaxy Clusters

open access: yesThe Astrophysical Journal, 2023
The radial acceleration relation (RAR) represents a tight empirical relation between the inferred total and baryonic centripetal accelerations, g _tot = GM _tot (< r )/ r ^2 and g _bar = GM _bar (< r )/ r ^2 , observed in galaxies and galaxy clusters ...

Sunyaev-Zel'dovich polarization as a probe of the intracluster medium [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2004
We present high-resolution hydrodynamical simulations of the degree and direction of polarisation imprinted on the CMB by the Sunyaev-Zel'dovich effect in the the line of sight to massive galaxy clusters. We focus on two contributions which contribute most of the induced CMB polarisation in addition to the intrinsic CMB quadrupole: the radiation ...

Explore your brain: A randomized controlled trial into the effectiveness of a growth mindset intervention with psychosocial and psychophysiological components

open access: yesBritish Journal of Educational Psychology, Volume 95, Issue 2, Page 280-302, June 2025.
Abstract Background Although past research demonstrated growth mindset interventions to improve school outcomes, effects were small. This may be due to the theoretical nature of psychosocial techniques (e.g., reading about brain plasticity), which may not be optimally convincing for students.

A chemical evolution model for galaxy clusters [PDF]

open access: yes, 2001
We develop a toy-model for the chemical evolution of the intracluster medium, polluted by the galactic winds from elliptical galaxies. The model follows the "galaxy formation history" of cluster galaxies, constrained by the observed luminosity function ...

Implications of a Nonthermal Origin of the Excess EUV Emission from the Coma Cluster of Galaxies

open access: yes, 1999
The inverse Compton (IC) interpretation of the excess EUV emission, that was recently reported from several clusters of galaxies, suggests that the amount of relativistic electrons in the intracluster medium is highly significant, W_e>10^{61} erg ...
