The Cluster HEritage project with XMM-Newton: Mass Assembly and Thermodynamics at the Endpoint of structure formation. I. Programme overview
Okabe, N.; Aussel, H.; Arnaud, M. +66 more
The Cluster HEritage project with XMM-Newton - Mass Assembly and Thermodynamics at the Endpoint of structure formation (CHEX-MATE) is a three-mega-second Multi-Year Heritage Programme to obtain X-ray observations of a minimally-biased, signal-to-noise-limited sample of 118 galaxy clusters detected by Planck through the Sunyaev-Zeldovich effect. Th…
APOGEE DR16: A multi-zone chemical evolution model for the Galactic disc based on MCMC methods
Calura, F.; Palla, M.; Matteucci, F. +6 more
Context. The analysis of the latest release of the Apache Point Observatory Galactic Evolution Experiment project (APOGEE DR16) data suggests the existence of a clear distinction between two sequences of disc stars at different Galactocentric distances in the [α/Fe] versus [Fe/H] abundance ratio space: the so-called high-α sequence, classically as…
Exploiting the Gaia EDR3 photometry to derive stellar temperatures
Massari, D.; Bellazzini, M.; Mucciarelli, A.
We present new colour-effective temperature (Teff) transformations based on the photometry of the early third data release (EDR3) of the ESA/Gaia mission. These relations are calibrated on a sample of about 600 dwarf and giant stars for which Teff has previously been determined with the infrared flux method from dereddened co…
The MUSE Extremely Deep Field: The cosmic web in emission at high redshift
Feltre, A.; Roth, M.; Steinmetz, M. +29 more
We report the discovery of diffuse extended Lyα emission from redshift 3.1 to 4.5, tracing cosmic web filaments on scales of 2.5−4 cMpc. These structures have been observed in overdensities of Lyα emitters in the MUSE Extremely Deep Field, a 140 h deep MUSE observation located in the Hubble Ultra-Deep Field. Among the 22 overdense regions identifi…
Infrared observations of the flaring maser source G358.93-0.03. SOFIA confirms an accretion burst from a massive young stellar object
Menten, K. M.; Eislöffel, J.; Klose, S. +24 more
Context. Class II methanol masers are signposts of massive young stellar objects (MYSOs). Recent evidence shows that flares of these masers are driven by MYSO accretion bursts. Thus, maser monitoring can be used to identify such bursts which are hard to discover otherwise. Infrared observations reveal burst-induced changes in the spectral energy d…
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…
