A Deep Dive into the NGC 741 Galaxy Group: Insights into a Spectacular Head-tail Radio Galaxy from VLA, MeerKAT, uGMRT, and LOFAR

open access: yesThe Astrophysical Journal
We present deep, wideband multifrequency radio observations (144 MHz−8 GHz) of the remarkable galaxy group NGC 741, which yield crucial insights into the interaction between the infalling head-tail radio galaxy (NGC 742) and the main group.

Has Politics Become More Professional? Career and Legislative Professionalisation in the Australian Parliament Since 1950

open access: yesAustralian Journal of Politics &History, EarlyView.
“Professional politicians” have been lamented for their perceived negative impact on representative democracy. However, the concept of “political professionalisation” is deployed inconsistently, making these claims difficult to assess. This article develops a framework to measure professionalisation across two dimensions: career professionalisation ...

Hedgehog: An Isolated Quiescent Dwarf Galaxy at 2.4 Mpc

open access: yesThe Astrophysical Journal Letters
It is well known that almost all isolated dwarf galaxies are actively forming stars. We report the discovery of dw1322m2053 (nicknamed Hedgehog), an isolated quiescent dwarf galaxy at a distance of 2.40 ± 0.15 Mpc with a stellar mass of M _⋆ ≈ 10 ^5.8 M ...

Relevance of ecological momentary assessment for medication adherence in clinical settings: A precision psychiatry approach

open access: yesBritish Journal of Clinical Psychology, EarlyView.
Abstract Background Medication non‐adherence is a leading cause of treatment failure in psychiatric populations. However, current studies highlight the lack of methodological guidance on medication assessments. Ecological Momentary Assessment (EMA), using smartphone‐based evaluations, shows promise for real‐time monitoring in everyday settings.

Computers and chess masters: The role of AI in transforming elite human performance

open access: yesBritish Journal of Psychology, EarlyView.
Abstract Advances in Artificial Intelligence (AI) have made significant strides in recent years, often supplementing rather than replacing human performance. The extent of their assistance at the highest levels of human performance remains unclear. We analyse over 11.6 million decisions of elite chess players, a domain commonly used as a testbed for AI

Hydrostatic Equilibrium Constraints in X-COP Galaxy Clusters: Testing Hyperconical Modified Gravity in Hot-gas-dominated Regions

open access: yesThe Astrophysical Journal
Modified Newtonian dynamics (MOND) was originally proposed to model galaxy rotation curves without dark matter. However, MOND presents difficulties in explaining the radial acceleration relation observed in galaxy clusters, and moreover, it does not ...

(2R,6R)‐hydroxynorketamine prevents opioid abstinence‐related negative affect and stress‐induced reinstatement in mice

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Opioid use disorder (OUD) is a pressing public health concern marked by frequent relapse during periods of abstinence, perpetuated by negative affective states. Classical antidepressants or the currently prescribed opioid pharmacotherapies have limited efficacy to reverse the negative affect or prevent relapse ...
