Unified Analysis of Fermionic Tunneling, Barrow‐Exponential Entropy Corrections, and Plasma Lensing in Carrollian Reissner‐Nordström Spacetime

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

Magellan Spectroscopy of Low-Redshift Active Galactic Nuclei

, 2009
We present an atlas of moderate-resolution (R ~ 1200-1600) optical spectra of 94 low-redshift (z < 0.5) active galactic nuclei taken with the Magellan 6.5 m Clay Telescope. The spectra mostly cover the rest-frame region 3600-6000 Ang.

PEARLS: Discovery of Point-source Features within Galaxies in the North Ecliptic Pole Time Domain Field

The Astrophysical Journal
The first public 0.9–4.4 μ m NIRCam images of the North Ecliptic Pole Time Domain Field uncovered galaxies displaying point-source features in their cores as seen in the longer-wavelength filters. We visually identified a sample of 66 galaxies (∼1 galaxy

Influence of radiotherapy dose rate on gold nanoparticle‐induced radiosensitization from high dose‐rate brachytherapy and external beam therapy

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Associated normal tissue toxicity from current radiotherapy (RT) treatments limits effective dose escalation in the tumor to achieve nominal treatment results. Gold nanoparticles (GNPs) as radiosensitizing agents to locally increase photoelectron production have gained interest as a safe and viable method to improve therapeutic ...

Mid-infrared Variability in Nearby Galaxies from the MaNGA Sample

The Astrophysical Journal
We use mid-infrared variability in galaxies to search for active galactic nuclei (AGN) in the local universe. We use a sample of 10,220 galaxies from the Mapping Nearby Galaxies at Apache Point Observatory survey, part of the Sloan Digital Sky Survey ...

Integrating Satellite‐Based and Participatory Spatial Analyses for Local, Contextualised, and Nuanced Extreme Heat Hotspot Mapping in Overheated Urban Southeast Asia

Sustainable Development, Volume 34, Issue S2, Page 1015-1033, March 2026.
ABSTRACT Rapid urbanisation in Southeast Asia intensifies extreme‐heat exposure, especially where high population density, extensive impervious surfaces, and limited green cover coincide. This study combines multi‐decadal satellite‐derived land surface temperature (LST) mapping with spatial regression and community participatory mapping to locate ...
