Polyphasic Characterization of Acetobacter indonesiensis UNPADCC 01-5 Isolated From a Traditional Fermented Food, Oncom Merah. [PDF]

open access: yesEnviron Microbiol Rep
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 ...

Revealing the dynamical behavior of stars in a prolate or oblate elliptical galaxy

open access: yesResults in Physics, 2023
We consider the motion of a test particle (star) on the meridian plane (R,z) of an elliptical galaxy with an additional central nucleus component. The shape of the elliptical galaxy can be either prolate or oblate, or even spherical by simply changing ...

Planetary Nebulae and the Ionization of the Interstellar Medium in Galaxies

open access: yesFrontiers in Astronomy and Space Sciences, 2022
We discuss the role of planetary nebulae and their progeny in galaxy context in terms of ionization of the galaxy interstellar medium. This regards ionized gas outside the disk of spiral galaxies, the diffuse ionized medium in spiral galaxies, and the ...

A repeating fast radio burst source localized to a nearby spiral galaxy [PDF]

open access: yesNature, 2020
Fast radio bursts (FRBs) are brief, bright, extragalactic radio flashes1,2. Their physical origin remains unknown, but dozens of possible models have been postulated3. Some FRB sources exhibit repeat bursts4–7.

Active Galactic Nucleus Feedback in an Elliptical Galaxy with the Most Updated AGN Physics. II. High Angular Momentum Case [PDF]

open access: yesAstrophysical Journal, 2017
This is the second paper of our series of works of studying the effects of active galactic nuclei (AGNs) feedback on the cosmological evolution of an isolated elliptical galaxy by performing two-dimensional hydrodynamical simulations.

New Resonance Scattering Model in AtomDB: Application to Line Suppression in Galaxy Clusters and Elliptical Galaxies

open access: yesThe Astrophysical Journal, 2023
In this paper, we present the simple, one-step, self-consistent, and fast resonance scattering model rsapec based on the AtomDB database. This model can be used as an alternative to the commonly used APEC model for fitting X-ray spectra with optically ...

Formation of Major Types of Galaxies Based on the Energy Circulation Theory

open access: yesReports in Advances of Physical Sciences, 2022
The standard cosmology can answer almost nothing about how the structure of a galaxy is formed. It expects a supermassive black hole at the center and dark matter in the halo to explain the circulation of stars and its velocity.

The effects of the vision on the central opacity and the positions of the curves invers for the brightness of the assumed elliptic sphere [PDF]

open access: yesمجلة التربية والعلم, 2006
The seeing effects on spherical symmetric Elliptical galaxy type EO following the r1/4- model has been calculated by using two type of the point spread function the Gaussian and Moffat functions .

Active Galactic Nucleus Feedback in an Elliptical Galaxy with the Most Updated AGN Physics. I. Low Angular Momentum Case [PDF]

open access: yes, 2017
We investigate the effects of AGN feedback on the cosmological evolution of an isolated elliptical galaxy by performing two-dimensional high-resolution hydrodynamical numerical simulations. The inner boundary of the simulation is chosen so that the Bondi
