Transient small-scale brightenings in the quiet solar corona: A model for campfires observed with Solar Orbiter
Berghmans, D.; Auchère, F.; Chen, Yajie +3 more
Context. Recent observations by the Extreme Ultraviolet Imager (EUI) on board Solar Orbiter have characterized prevalent small-scale transient brightenings in the corona above the quiet Sun termed campfires.
Aims: In this study we search for comparable brightenings in a numerical model and then investigate their relation to the magnetic field…
Dust polarized emission observations of NGC 6334. BISTRO reveals the details of the complex but organized magnetic field structure of the high-mass star-forming hub-filament network
Kim, J.; Tamura, M.; Savini, G. +146 more
Context. Molecular filaments and hubs have received special attention recently thanks to new studies showing their key role in star formation. While the (column) density and velocity structures of both filaments and hubs have been carefully studied, their magnetic field (B-field) properties have yet to be characterized. Consequently, the role of B…
Gaia Early Data Release 3. Building the Gaia DR3 source list - Cross-match of Gaia observations
Biermann, M.; Lindegren, L.; Bastian, U. +12 more
Context. The Gaia Early Data Release 3 (Gaia EDR3) contains results derived from 78 billion individual field-of-view transits of 2.5 billion sources collected by the European Space Agency's Gaia mission during its first 34 months of continuous scanning of the sky.
Aims: We describe the input data, which have the form of onboard detections, an…
Kiloparsec view of a typical star-forming galaxy when the Universe was ∼1 Gyr old. I. Properties of outflow, halo, and interstellar medium
Lutz, D.; Genzel, R.; Förster Schreiber, N. +9 more
We present new Atacama Large Millimeter/Submillimeter Array observations of the [C II] 158 µm transition and the dust continuum in HZ4, a typical star-forming galaxy when the Universe was only ∼1 Gyr old (z ≈ 5.5). Our high ≈0.3″ spatial resolution allows us to study the relationships between [C II] line emission, star formation rate, and fa…
SWEET-Cat 2.0: The Cat just got SWEETer. Higher quality spectra and precise parallaxes from Gaia eDR3
Adibekyan, V.; Hoyer, S.; Sousa, S. G. +13 more
Aims: The catalog of Stars With ExoplanETs (SWEET-Cat) was originally introduced in 2013. Since then many more exoplanets have been confirmed, increasing significantly the number of host stars listed there. A crucial step toward a comprehensive understanding of these new worlds is the precise and homogeneous characterization of their host sta…
Fast rotating and low-turbulence discs at z ≃ 4.5: Dynamical evidence of their evolution into local early-type galaxies
Magnelli, B.; Gómez-Guijarro, C.; Jiménez-Andrade, E. F. +3 more
Massive starburst galaxies in the early Universe are estimated to have depletion times of ∼100 Myr and thus be able to convert their gas very quickly into stars, possibly leading to a rapid quenching of their star formation. For these reasons, they are considered progenitors of massive early-type galaxies (ETGs). In this paper, we study two high-z…
CHEOPS observations of the HD 108236 planetary system: a fifth planet, improved ephemerides, and planetary radii
Guterman, P.; Alonso, R.; Deleuil, M. +106 more
Context. The detection of a super-Earth and three mini-Neptunes transiting the bright (V = 9.2 mag) star HD 108236 (also known as TOI-1233) was recently reported on the basis of TESS and ground-based light curves.
Aims: We perform a first characterisation of the HD 108236 planetary system through high-precision CHEOPS photometry and improve t…
Milky Way spiral arms from open clusters in Gaia EDR3
Castro-Ginard, A.; Jordi, C.; Luri, X. +7 more
Context. The physical processes driving the formation of Galactic spiral arms are still under debate. Studies using open clusters favour the description of the Milky Way spiral arms as long-lived structures following the classical density wave theory. Current studies comparing the Gaia DR2 field stars kinematic information of the solar neighbourho…
Validation of the accuracy and precision of Gaia EDR3 parallaxes with globular clusters
Maíz Apellániz, J.; Barbá, R. H.; Pantaleoni González, M.
Context. The recent early third data release (EDR3) from the Gaia mission has produced parallaxes for 1.468 × 109 sources with better quality than those reported in the previous data release. Nevertheless, there are calibration issues with the data that require corrections to the published values and uncertainties.
Aims: We want to…
The Abell 3391/95 galaxy cluster system. A 15 Mpc intergalactic medium emission filament, a warm gas bridge, infalling matter clumps, and (re-) accelerated plasma discovered by combining SRG/eROSITA data with ASKAP/EMU and DECam data
Diego, J. M.; Salvato, M.; Nandra, K. +44 more
Context. Inferences about dark matter, dark energy, and the missing baryons all depend on the accuracy of our model of large-scale structure evolution. In particular, with cosmological simulations in our model of the Universe, we trace the growth of structure, and visualize the build-up of bigger structures from smaller ones and of gaseous filamen…
