Galaxy Merging and the Fundamental Plane of Elliptical Galaxies [PDF]
, 2006 We present preliminary results of numerical simulations of dissipationless merging of stellar systems, aimed at exploring the consequences of merging between gas free, spheroidal systems. In particular, we study the dynamical and structural characteristics of hierarchical merging between equal mass stellar systems, and we compare the properties of the ...

Journal of Geophysical Research: Space Physics, Volume 130, Issue 1, January 2025.Abstract The dynamics of giant planet magnetospheres is controlled by a complex interplay between their fast rotation, their interaction with the solar wind, and their diverse internal plasma and momentum sources. In the ionosphere, the Hall and Pedersen conductances are two key parameters that regulate the intensity of currents coupling the ...

Two-component mass models of the lensing galaxy in the quadruply imaged supernova iPTF16geu
The Open Journal of Astrophysics, 2020 The first resolved, multiply imaged supernova Type Ia, iPTF16geu, was observed 4 years ago, five decades after such systems were first envisioned. Because of the unique properties of the source, these systems hold a lot of promise for the study of galaxy

Journal of Nutrition and Metabolism, Volume 2025, Issue 1, 2025.This study examined the health benefits of 3‐O‐butanoylresveratrol (ED4), a monoester derivative of resveratrol butyrate esters. Using a high‐calorie diet model simulation with Chinese sausage, ED4 was tested against changes in physiological indices like body weight (BW), body fat, blood pressure, and SCFA levels (stools and serum) in rats.

The Stellar Kinematics of Elliptical Galaxies [PDF]
Symposium - International Astronomical Union, 1987 The kinematic properties of elliptical galaxies are summarized. New developments are discussed in four areas: (i) the Faber-Jackson relation and the role of second parameters (ii) the luminosity-rotation relation (iii) the figures of elliptical galaxies and (iv) the mass-to-light ratio as a function of radius.

Deep Synoptic Array Science: Two Fast Radio Burst Sources in Massive Galaxy Clusters
The Astrophysical Journal Letters, 2023 The hot gas that constitutes the intracluster medium (ICM) has been studied at X-ray and millimeter/submillimeter wavelengths (Sunyaev–Zel’dovich effect) for decades.

Alignment and morphology of elliptical galaxies: the influence of the cluster tidal field
, 1994 We investigate two possible effects of the tidal field induced by a spherical cluster on its elliptical galaxy members: the modification of the ellipticity of a spherical galaxy and the isophotal alignment in the cluster radial direction of a misaligned ...

ArtProtect: Blockchain and NFC‐based anti‐counterfeit system for physical art
IET Blockchain, Volume 4, Issue 4, Page 423-442, December 2024.An anti‐counterfeiting system for physical art based on Ethereum blockchain and near‐field communication technology is proposed and implemented. The system leverages the use of Ethereum smart contracts and inter‐planetary file system to store artworks’ certificate of authenticity, and display them in a mobile app called ArtProtect.

Dynamical Models of Elliptical Galaxies [PDF]
Symposium - International Astronomical Union, 1975 Self-consistent dynamical models of elliptical galaxies have been constructed using a modification of the Prendergast-Tomer algorithm. They reproduce many of the observed properties of elliptical galaxies.

NO THE HOLMBERG EFFECT FOR GALAXY PAIRS SELECTED FROM THE SDSS DR9 AT Z ≤ 0:06
Odessa Astronomical Publications, 2016 We studied the Holmberg effect in galaxy pairs selected from the SDSS DR9, where 60561galaxies were limited by redshift 0.02 < z < 0.06 and absolute magnitude: Mr ≤ −20.7 m for central galaxies (N=18578) and Mr > −21.5 m for neighbor galaxies (N=41983 ...
