Annalen der Physik, Volume 538, Issue 3, March 2026.Carrollian Reissner‐Nordström black holes are investigated through fermionic tunneling, entropy‐corrected thermodynamics, and plasma‐modified gravitational lensing. The generalized uncertainty principle introduces minimal‐length corrections to the Hawking temperature, while the combined Barrow‐Exponential entropy reveals smooth thermodynamic crossovers

The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release
Astronomische Nachrichten, Volume 347, Issue 3, March 2026.ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

Active Galactic Nucleus Jet-inflated Bubbles as Possible Origin of Odd Radio Circles
The Astrophysical JournalOdd radio circles (ORCs) are newly discovered extragalactic radio objects with an unknown origin. In this work, we carry out three-dimensional cosmic-ray (CR) magnetohydrodynamic simulations using the FLASH code and predict the radio morphology of end-on

ACTIVE GALACTIC NUCLEUS FEEDBACK IN THE HOT HALO OF NGC 4649
The Astrophysical Journal, 2014 Using the deepest available Chandra observations of NGC 4649, we find strong evidences of cavities, ripples, and ring-like structures in the hot interstellar medium that appear to be morphologically related with the central radio emission. These structures show no significant temperature variations in correspondence with higher pressure regions (0.5 ...

Energy Technology, Volume 14, Issue 3, March 2026.The BA2MA3Pb4I13, where (BA is butylammonium, MA is methylammonium) quasi‐2D halide perovskites are identified as a promising material with a suitable bandgap of 1.9 eV for indoor light harvesting. A combination of lower thickness of 260 nm, better phase purity and greater (202) crystal orientation obtained from preheating, yielded a champion power ...

Quantifying the Active Galactic Nucleus Fraction in Cosmic Voids via Mid-infrared Variability
The Astrophysical JournalObservations and theoretical simulations suggest that the large-scale environment plays a significant role in how galaxies form and evolve and, in particular, whether and when galaxies host an actively accreting supermassive black hole in their center (i.
