50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

Experimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

Investigating the Kinematics of Central and Satellite Galaxies Using Normalizing Flows

The Astrophysical Journal
Galaxy clustering contains information on cosmology, galaxy evolution, and the relationship between galaxies and their dark matter hosts. On small scales, the detailed kinematics of galaxies within their host halos determines the galaxy clustering.

When was the Large Magellanic Cloud accreted onto the Galaxy ?

, 2011
Using fully self-consistent N-body models for the dynamical evolution of the Large Magellanic Cloud (LMC) in the Galaxy, we show that if the LMC initially has an extended old stellar halo before its commencement of tidal interaction with the Galaxy ...

Kinematic and stellar population properties of the counter-rotating components in the S0 galaxy NGC 1366 [PDF]

, 2017
Context. Many disk galaxies host two extended stellar components that rotate in opposite directions. The analysis of the stellar populations of the counter-rotating components provides constraints on the environmental and internal processes that drive ...

KINEMATIC EVOLUTION OF SIMULATED STAR-FORMING GALAXIES [PDF]

The Astrophysical Journal, 2014
Recent observations have shown that star-forming galaxies like our own Milky Way evolve kinematically into ordered thin disks over the last ~8 billion years since z=1.2, undergoing a process of "disk settling." For the first time, we study the kinematic evolution of a suite of four state of the art "zoom in" hydrodynamic simulations of galaxy formation

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Kinematical & Chemical Characteristics of the Thin and Thick Disks [PDF]

, 2008
I discuss how the chemical abundance distributions, kinematics and age distributions of stars in the thin and thick disks of the Galaxy can be used to decipher the merger history of the Milky Way, a typical large galaxy. The observational evidence points

Internal kinematics of isolated modelled disc galaxies [PDF]

Astronomy & Astrophysics, 2006
We present a systematic investigation of rotation curves (RCs) of fully hydrodynamically simulated galaxies, including cooling, star formation with associated feedback and galactic winds. Applying two commonly used fitting formulae to characterize the RCs, we investigate systematic effects on the shape of RCs both by observational constraints and ...

A Possible Solution to the Mystery of the ANITA Anomalous Events

Annalen der Physik, Volume 538, Issue 4, April 2026.
In 2006 and 2014, the Antarctic Impulsive Transient Antenna (ANITA), a balloon‐borne radio observatory flying over Antarctica, detected two strange upward‐going radio pulse events that have not yet been explained by our current understanding of physics.

The assembly history of the nearest S0 galaxy NGC 3115 from its kinematics out to six half-light radii [PDF]

, 2020
Using new and archival data, we study the kinematic properties of the nearest field S0 galaxy, NGC 3115, out to $\sim6.5$ half-light radii ($R_\mathrm{e}$) from its stars (integrated starlight), globular clusters (GCs) and planetary nebulae (PNe).
