Skymaps of observables of three-dimensional magnetohydrodynamic astrosphere models [PDF]

Astronomy & Astrophysics, 2020
Context. Three-dimensional models of astrospheres have recently become of interest. However, comparisons between these models and observations are non-trivial because of the two-dimensional nature of observations. Aims.

Towards DIB mapping in galaxies beyond 100 Mpc. A radial profile of the $\lambda$5780.5 diffuse interstellar band in AM 1353-272 B [PDF]

, 2015
Diffuse Interstellar Bands (DIBs) are non-stellar weak absorption features of unknown origin found in the spectra of stars viewed through one or several clouds of Interstellar Medium (ISM). Research of DIBs outside the Milky Way is currently very limited.

Detection of magnetic field in the B2 star $\rho$ Oph A with ESO FORS2 [PDF]

, 2017
Circumstantial evidence suggests that magnetism and enhanced X-ray emission are likely correlated in early B-type stars: similar fractions of them ($\sim$ 10 %) are strong and hard X-ray sources and possess strong magnetic fields.

Nucleon-nucleon scattering in the 1S0 partial wave in the modified Weinberg approach

EPJ Web of Conferences, 2016
Nucleon-nucleon scattering in the 1S0 partial wave is considered in chiral effective field theory within the recently suggested renormalizable formulation based on the Kadyshevsky equation.

High-resolution 21-cm observations of low-column density gas clumps in the Milky Way halo [PDF]

, 2009
Aims. We study the properties of low-column density gas clumps in the halo of the Milky Way based on high-resolution 21-cm observations. Methods. Using interferometric data from the Westerbork Synthesis Radio Telescope (WSRT) and the Very Large Array ...

Hot bubbles of planetary nebulae with hydrogen-deficient winds. I. Heat conduction in a chemically stratified plasma [PDF]

, 2015
Heat conduction has been found a plausible solution to explain discrepancies between expected and measured temperatures in hot bubbles of planetary nebulae (PNe).

HVC and IVC Gas in the Halo of the Milky Way [PDF]

, 2006
We combine CaII/NaI absorption and HI 21 cm emission line measurements to analyse the metal abundances, the distribution, the small-scale structure, and the physical conditions of intermediate- and high-velocity gas in the Galactic halo.

The population of Galactic supernova remnants in the TeV range [PDF]

EPJ Web of Conferences
Galactic Supernova remnants (SNRs) are likely to be significant sources of cosmic rays (CRs) up to the knee of the CR spectrum. They produce gamma rays in the very-high-energy (VHE) range.

Analysis of the temperature- and fluence-dependent magnetic stress in laser-excited SrRuO3

Structural Dynamics, 2021
We use ultrafast x-ray diffraction to investigate the effect of expansive phononic and contractive magnetic stress driving the picosecond strain response of a metallic perovskite SrRuO3 thin film upon femtosecond laser excitation.

Turbulence in Accretion Disks: Vorticity Generation and Angular Momentum Transport via the Global Baroclinic Instability [PDF]

, 2002
In this paper we present the global baroclinic instability as a source for vigorous turbulence leading to angular momentum transport in Keplerian accretion disks.
