Predictive modeling of Super El Niño through integrated local and global climate signals

Scientific Reports
Recent surges in extreme weather events underscore the critical need for advanced climate prediction models. Super El Niño (SE) events, characterized by unprecedented climatic and economic impacts, have intensified global concerns.

Large scale hydrodynamic modes of oscillations in gaseous disks of flat galaxies with a kink on rotation curves

Open Astronomy, 2018
The properties of unstable large-scale hydrodynamic (HD) modes of oscillations in the gaseous disk of a flat galaxy with a rotation curve having a velocity jump in the inner region of the disk are numerically investigated.

ZELDOVICH LOCAL PANCAKE: DARK ENERGY DOMINATION

Odessa Astronomical Publications, 2018
Zeldovich Local Pancake is a two-dimensional system of 15 giant galaxies nearest to us. Two of the galaxies, the Milky Way and the Andromeda Galaxy, move to each other in the Local Group, while the rest of the galaxies are located around the group at ...

Ion alfvén velocity fluctuations and implications for the diffusion of streaming cosmic rays

Frontiers in Astronomy and Space Sciences, 2022
The interstellar medium (ISM) of star-forming galaxies is magnetized and turbulent. Cosmic rays (CRs) propagate through it, and those with energies from ∼ GeV − TeV are likely subject to the streaming instability, whereby the wave damping processes ...

What Are S0 Galaxies?

, 2009
The data collected in the Shapley-Ames catalog of bright galaxies show that lenticular (S0) galaxies are typically about a magnitude fainter than both elliptical (E) and early spiral (Sa) galaxies.

Edible Pneumatic Battery for Sustained and Repeated Robot Actuation

Advanced Science, EarlyView.
This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Emission Knots and Polarization Swings of Swinging Jets

Galaxies, 2016
Knots (emission features in jets of active galactic nuclei) often show non-ballistic dynamics and variable emission/polarization properties. We model these features as emission pattern propagating in a jet that carries a helical magnetic field and is ...

A Stellar Mass Threshold for Quenching of Field Galaxies

, 2012
We demonstrate that dwarf galaxies (10^7 < M_stellar < 10^9 Msun) with no active star formation are extremely rare (
