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

open access: yesAnnalen 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 astrophysical behavior of open clusters along the Milky Way Galaxy

open access: yesNRIAG Journal of Astronomy and Geophysics, 2014
The main aim of this paper is to study the astrophysical behavior of open clusters' properties along the Milky Way Galaxy. Near-IR JHK (2MASS) photometry has been used for getting a homogeneous Catalog of 263 open clusters' parameters, which are studied for the first time by the author through the last five years.

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

open access: yesAstronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release

open access: yesAstronomische 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 ...

Accelerated Knowledge Discovery: A Vision for NASA Science

open access: yesEarth and Space Science, Volume 13, Issue 3, March 2026.
Abstract This paper introduces the sixth paradigm of scientific discovery: accelerated knowledge discovery (AKD). This paradigm is defined by the full integration of artificial intelligence (AI) into the research workflow as a tool augmenting cognitive capabilities of human scientists.

Characterizing the Signals and Backgrounds in a Low Earth Orbiting Cherenkov Detector, and Background Mitigation Strategies

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Cherenkov detectors have been used in space for decades to measure Galactic Cosmic Rays (GCRs), Solar Energetic Particles (SEPs) and trapped particles. We present proof‐of‐concept GRAS/Geant4 simulations to both show that a cubic fused silica Cherenkov detector with SiPM in LEO has a good sensitivity to SEP and GCR protons as a function of cut‐

DART: A Dual Aperture Relativistic Electron Telescope for Smallsats

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The precipitation of particles into the Earth's atmosphere is a primary loss mechanism of the radiation belt for which many unknowns remain. With the growing number of space mission concepts to solve them, less expensive alternatives such as CubeSats are being used.

Astrophysics: The slow death of red galaxies.

open access: yesNature, 2015
For most galaxies, the shutdown of star formation was a slow process that took 4 billion years. An analysis of some 27,000 galaxies suggests that 'strangulation' by their environment was the most likely cause.
