摘要:Context. Mergers of galaxy clusters are among the most energetic events in the Universe. These events have significant impact on the intra-cluster medium, depositing vast amounts of energy, often in the form of shocks, as well as heavily influencing the properties of the con...

摘要:Multiconfiguration Dirac-Hartree-Fock (MCDHF) calculations and relativistic configuration interaction (RCI) calculations were performed for states of the 3 l 3 l ′ , 3 l 4 l ′ and 3 s 5 l configurations in the Mg-like ions Ca IX – As XXII and Kr XXV. Valence and core-va...

摘要:Context. Mid-IR water lines from protoplanetary disks around T Tauristars have a detection rate of 50%. Models have identified multiple physical properties ofdisks such as dust-to-gas mass ratio, dust size power law distribution, disk gas mass,disk inner radius, and disk sca...

摘要:Aims. We aim to investigate how converging flows towards active regions affect the surface transport of magnetic flux, as well as their impact on the generation of the Sun’s poloidal field. The inflows constitute a potential non-linear mechanism for the saturation of the glo...

摘要:Context. Submillimetre galaxies (SMGs) in the early Universe are potential antecedents of the most massive galaxies we see in the present-day Universe. An important step towards quantifying this galactic evolutionary connection is to investigate the fundamental physical prop...

摘要:We report on the first proper motion measurement in the supernova remnant RX J1713.7 − 3946 using the XMM-Newton X-ray telescope on a 13 yr time interval. This expansion measurement is carried out in the south-east region of the remnant, where two sharp filament structures a...

摘要:We present our analysis of EPIC 211779126, a pulsating subdwarf B star discovered with the Kepler spacecraft during K2 Campaign 5. We found 154 frequencies in the g -mode region as well as 29 frequencies in the p -mode region. This makes EPIC 211779126 a rare hybrid pulsator...

摘要:Context. Stellar kinematic groups are kinematically coherent groups of stars that might have a common origin. These groups spread through the Galaxy over time owing to tidal effects caused by Galactic rotation and disk heating. However, the chemical information survives thes...

摘要:Aims. NGC 2617 is a nearby ( z ~ 0.01 ) active galaxy that recently switched from being a Seyfert 1.8 to be a Seyfert 1.0. At the same time, it underwent a strong increase of X-ray flux by one order of magnitude with respect to archival measurements. We characterise the X-ra...

摘要:We make quantitative estimates of the power supplied to the Galactic cosmic ray population by second-order Fermi acceleration in the interstellar medium, or as it is usually termed in cosmic ray propagation studies, diffusive reacceleration. Using recent results on the local...
