Radial Profiles of the Binary Fraction in Elliptical Galaxies
The Astrophysical JournalThe radial profile of the binary fraction may vary with environment and is of significant importance for studying the formation mechanisms of binary stars and their dynamical evolution within globular clusters and galaxies.

FEEDBACK FROM CENTRAL BLACK HOLES IN ELLIPTICAL GALAXIES. III. MODELS WITH BOTH RADIATIVE AND MECHANICAL FEEDBACK [PDF]
, 2010 We find, from high-resolution hydro simulations, that winds from active galactic nuclei effectively heat the inner parts (≈100 pc) of elliptical galaxies, reducing infall to the central black hole; and radiative (photoionization and X-ray) heating ...

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer
Radio Science, Volume 61, Issue 6, June 2026.Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Surface Photometry of Spiral Galaxy NGC 5005 and Elliptical Galaxy NGC 4278
مجلة بغداد للعلوم, 2018 Two galaxies have been chosen, spiral galaxy NGC 5005 and elliptical galaxy NGC 4278 to study their photometric properties by using surface photometric techniques with griz-Filters. Observations are obtained from the Sloan Digital Sky Survey (SDSS).

STELLAR POPULATIONS OF ELLIPTICAL GALAXIES IN THE LOCAL UNIVERSE [PDF]
, 2010 We study the stellar populations of 1923 elliptical galaxies at z < 0.05 selected from the Sloan Digital Sky Survey as a function of velocity dispersion, σ, and environment.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

ELLIPTICITIES OF ELLIPTICAL GALAXIES IN DIFFERENT ENVIRONMENTS
The Astrophysical Journal, 2016 ABSTRACT We studied the ellipticity distributions of elliptical galaxies in different environments. From the ninth data release of the Sloan Digital Sky Survey, we selected galaxies with absolute -band magnitudes between −21 and −22.

The Open Journal of AstrophysicsAlignments of disc galaxies were thought to result from tidal torquing, where tidal field of the cosmic large-scale structure exert torquing moments onto dark matter haloes, determining their angular momentum and ultimately the orientation of galactic ...

Galactic Structures from Gravitational Radii
Galaxies, 2018 We demonstrate that the existence of a Noether symmetry in f ( R ) theories of gravity gives rise to an additional gravitational radius, besides the standard Schwarzschild one, determining the dynamics at galactic scales.

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.The polyphasic approach (morphology, physiology, biochemistry and genetics) was used to characterize Acetobacter indonesiensis strain UNPADCC 01‐5, which was isolated from oncom merah. The strain's potential as a culture for acidic fermentations and a biofunctional agent was supported by its adaptive characteristics, which included acid tolerance ...
