Prospects for Revealing Intermediate-mass Black Holes in NGC 1399 Using SKA

open access: yesThe Astrophysical Journal
This study investigates the detectability of intermediate-mass black holes (IMBHs) within the mass range 10 ^2 M _⊙ ≤ M _BH ≤ 10 ^5 M _⊙ in the globular star clusters of NGC 1399 at a frequency of 300.00 MHz.

Slowly Rotating Accretion Flow Around Supermassive Black Holes in Elliptical Galaxies: Case With Outflow

open access: yesThe Astrophysical Journal, 2023
Observational evidence and many numerical simulations show the existence of winds (i.e., uncollimated outflows) in the accretion systems of elliptical galaxy centers.

Isothermal Bondi Accretion in Two-component Jaffe Galaxies with a Central Black Hole [PDF]

open access: yes, 2018
The fully analytical solution for isothermal Bondi accretion onto a black hole (MBH) at the center of two-component Jaffe galaxy models is presented. In a previous work, we provided the analytical expressions for the critical accretion parameter and the ...

Copolymers of Poly(Butylene Trans‐1,4‐Cyclohexanedicarboxylate)/Pripol as New Biomaterial Platform for Small Diameter Vascular Graft

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 23, 19 June 2026.
Electrospun tubular scaffolds from novel PBCE‐based copolyesters and blends were designed as candidates for small‐diameter vascular grafts. They combine defect‐free architecture, blood‐compatible surfaces, and mechanical properties comparable to native vessels.

Bridging Scales in Black Hole Accretion and Feedback: Relativistic Jet Linking the Horizon to the Host Galaxy

open access: yesThe Astrophysical Journal
Simulating black hole (BH) accretion and feedback from the BH horizon to galactic scales is extremely challenging, as it involves a vast range of scales.

Effects of extreme mountain ultramarathon on stress‐related biomarkers from multiple biological matrices in adult male runners

open access: yesPhysiological Reports, Volume 14, Issue 11, June 2026.
Abstract Prior investigations concerning finishers of the Tor des Géants (TDG) have demonstrated oxi‐inflammatory response. MicroRNAs (miRNAs) have been identified as prospective biomarkers for oxi‐inflammatory and stress responses. This study addressed the acute responses concerning salivary miRNAs, circulating redox markers and urinary exercise ...

Bridging Scales in Black Hole Accretion and Feedback: Subgrid Prescription from First Principles

open access: yesThe Astrophysical Journal Letters
Understanding how supermassive black holes (BHs) couple to their host galaxies across a vast spatial and temporal dynamic range remains a central challenge in galaxy evolution.

Bondi accretion in the spherically symmetric Johannsen–Psaltis spacetime

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The Johannsen–Psaltis spacetime explicitly violates the no-hair theorem. It describes rotating black holes with scalar hair in the form of parametric deviations from the Kerr metric.

Metabotropic glutamate receptor 5 is associated with plasma GFAP dependent on age

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION We investigated the relationship between metabotropic glutamate receptor subtype 5 (mGluR5) availability and plasma biomarkers in individuals with cognitive impairment. METHODS Seventy‐one subjects were included (17 cognitively unimpaired [CU], 10 early‐onset cognitive impairment [EOCI], and 44 late‐onset cognitive impairment ...

Multizone Modeling of Black Hole Accretion and Feedback in 3D GRMHD: Bridging Vast Spatial and Temporal Scales

open access: yesThe Astrophysical Journal
Simulating accretion and feedback from the horizon scale of supermassive black holes (SMBHs) out to galactic scales is challenging because of the vast range of scales involved. Elaborating on H.
