Structure and Kinematics of Early-Type Galaxies from Integral Field Spectroscopy [PDF]
, 2016 Observations of galaxy isophotes, long-slit kinematics, and high-resolution photometry suggested a possible dichotomy between two distinct classes of elliptical galaxies. But these methods are expensive for large galaxy samples.

The Magnetosphere‐Ionosphere‐Ground Responses to the May 2024 Super Solar Storm
Space Weather, Volume 23, Issue 4, April 2025.Abstract Earth suffered the attack of the strongest geomagnetic storm in the last 20 years (Kp = 9, Dst∼ ${\sim} $ −400 nT) occurred on 11 May 2024. Taking advantage of the LEO multi‐parameter CSES satellite (launched in 2018) with a large inclination angle 97° $97{}^{\circ}$, with the joint observations of NOAA and GOES, we present a comprehensive ...

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.

Dynamical Family Properties and Dark Halo Scaling Relations of Giant Elliptical Galaxies [PDF]
, 2000 Based on a uniform dynamical analysis of the line-profile shapes of 21 mostly luminous, slowly rotating, and nearly round elliptical galaxies, we have investigated the dynamical family relations and dark halo properties of ellipticals.

Environmental Microbiology Reports, Volume 17, Issue 2, April 2025.The quorum sensing regulated sRNA Lrs1 participates in the adaptation of Pseudomonas aeruginosa in low iron by downregulating the siderophore pyochelin, the Quorum Sensing system PQS, and its associated virulence factor phenazines. ABSTRACT Iron is an essential nutrient for microbial growth. The opportunistic pathogen Pseudomonas aeruginosa can survive

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 ...

SIMULATIONS OF LARGE-SCALE GASEOUS STRUCTURES WITH SPH
Odessa Astronomical Publications, 2017 A computer programme based on the 3D SPH approach is described. Some numerical results are presented: the formation of gaseous ring around an SO galaxy due to the stripping of a gas-rich donor system.

The SAURON project - IV. The mass-to-light ratio, the virial mass estimator and the Fundamental Plane of elliptical and lenticular galaxies [PDF]
, 2005 We investigate the well-known correlations between the dynamical mass-to-light ratio M/L and other global observables of elliptical (E) and lenticul ar (S0) galaxies.

Plant Pathology, Volume 74, Issue 3, Page 605-640, April 2025.The literature cites many alternative hosts of Phytophthora erythroseptica. However, evidence of host status is often insufficient, thus a polyphasic approach (morphological, molecular, histological and pathogenicity) is required. ABSTRACT Most published studies of Phytophthora erythroseptica, the major causal agent of pink rot of potato, have focused ...

Dynamical Models of Spherical Galaxies with Massive Halo [PDF]
Journal of Astronomy and Space Sciences, 2003 Using the Schwarzschild's linear programming technique, we obtained the general solutions of the collisionless Bolzmann equation describing the spherical galaxy in dynamical equilibrium.
