Rivers of gas – I. Unveiling the properties of high redshift filaments by Ramsøy, M, Slyz, A, Devriendt, J, Laigle, C, Dubois, Y

Such an analytic model also predicts a redshift evolution for the core radius of filaments in fair agreement with the measured value for DM [r0∝ (1 + z)−3.18 ± 0.28]. …”

Stellar equilibrium configurations of white dwarfs in the f(R, T) gravity by G. A. Carvalho, R. V. Lobato, P. H. R. S. Moraes, José D. V. Arbañil, E. Otoniel, R. M. Marinho, M. Malheiro

“…Considering the functional form $$f(R,T)=R+2\lambda T$$ f ( R , T ) = R + 2 λ T , with $$\lambda $$ λ being a constant, we obtain the hydrostatic equilibrium equation for the theory. Some physical properties of white dwarfs, such as: mass, radius, pressure and energy density, as well as their dependence on the parameter $$\lambda $$ λ are derived. …”

Automatic delineation of glacier grounding lines in differential interferometric synthetic-aperture radar data using deep learning by Yara Mohajerani, Seongsu Jeong, Bernd Scheuchl, Isabella Velicogna, Eric Rignot, Pietro Milillo

“…Along the Getz Ice Shelf, in West Antarctica, we demonstrate that grounding zones are one order magnitude (13.3 ± 3.9) wider than expected from hydrostatic equilibrium, which justifies the need to map grounding lines repeatedly and comprehensively to inform numerical models.…”

Constraining the mass and redshift evolution of the hydrostatic mass bias using the gas mass fraction in galaxy clusters by Wicker R., Douspis M., Salvati L., Aghanim N.

“…Among different aspects of the baryonic physics, in these proceedings we focus on the impact of the hydrostatic equilibrium assumption. From X-ray measurements of cluster gas fraction in the Planck-ESZ sample, we analyse the hydrostatic mass bias B, constraining a possible mass and redshift evolution of this quantity and its impact on the cosmological constraints. …”

Predawn leaf water potential of grapevines is not necessarily a good proxy for soil moisture by Thomas Groenveld, Charles Obiero, Yingxue Yu, Markus Flury, Markus Keller

“…Abstract Background In plant water relations research, predawn leaf water potential (Ψpd) is often used as a proxy for soil water potential (Ψsoil), without testing the underlying assumptions that nighttime transpiration is negligible and that enough time has passed for a hydrostatic equilibrium to be established. The goal of this research was to test the assumption Ψpd = Ψsoil for field-grown grapevines. …”

High-resolution Study of Planetesimal Formation by Gravitational Collapse of Pebble Clouds by Brooke Polak, Hubert Klahr

“…We use the multiphysics code GIZMO to model the pebble cloud density as a continuum, with a polytropic equation of state to account for collisional interactions and capturing the phase transition to a quasi-incompressible “solid” object, i.e., a planetesimal in hydrostatic equilibrium. Thus, we study cloud collapse effectively at the resolution of the forming planetesimals, allowing us to derive an initial mass function for planetesimals in relation to the total pebble mass of the collapsing cloud. …”
