The ART-XC telescope on board the SRG observatory
Sunyaev, R.; Krivonos, R.; Sazonov, S. +59 more
Astronomical Roentgen Telescope - X-ray Concentrator (ART-XC) is the hard X-ray instrument with grazing incidence imaging optics on board the Spektr-Roentgen-Gamma (SRG) observatory. The SRG observatory is the flagship astrophysical mission of the Russian Federal Space Program, which was successively launched into orbit around the second Lagrangia…
Cosmological implications of the anisotropy of ten galaxy cluster scaling relations
Lovisari, L.; Pacaud, F.; Ramos-Ceja, M. E. +5 more
The hypothesis that the late Universe is isotropic and homogeneous is adopted by most cosmological studies, including studies of galaxy clusters. The cosmic expansion rate H0 is thought to be spatially constant, while bulk flows are often presumed to be negligible compared to the Hubble expansion, even at local scales. The effects of bu…
A nearby galaxy perspective on dust evolution. Scaling relations and constraints on the dust build-up in galaxies with the DustPedia and DGS samples
De Looze, Ilse; Baes, Maarten; Fritz, Jacopo +13 more
Context. The efficiency of the different processes responsible for the evolution of interstellar dust on the scale of a galaxy are, to date, very uncertain, spanning several orders of magnitude in the literature. Yet, precise knowledge of the grain properties is key to addressing numerous open questions about the physics of the interstellar medium…
Stellar chromospheric activity of 1674 FGK stars from the AMBRE-HARPS sample. I. A catalogue of homogeneous chromospheric activity
Recio-Blanco, A.; de Laverny, P.; Monteiro, M. J. P. F. G. +9 more
Aims: The main objective of this project is to characterise chromospheric activity of FGK stars from the HARPS archive. We start, in this first paper, by presenting a catalogue of homogeneously determined chromospheric emission (CE), stellar atmospheric parameters, and ages for 1674 FGK main sequence (MS), subgiant, and giant stars. The analy…
Internal calibration of Gaia BP/RP low-resolution spectra
Jordi, C.; Evans, D. W.; van Leeuwen, F. +6 more
Context. The full third Gaia data release will provide, for the first time, the calibrated spectra obtained with the blue and red Gaia slitless spectrophotometers (BP and RP, respectively). Gaia is a very complex mission and cannot be considered as a single instrument, but rather as many instruments. The two lines of sight with wide fields of view…
The ALPINE-ALMA [CII] survey. Obscured star formation rate density and main sequence of star-forming galaxies at z > 4
Cimatti, A.; Maiolino, R.; Pozzi, F. +30 more
Star formation rate (SFR) measurements at z > 4 have relied mostly on the rest-frame far-ultraviolet (FUV) observations. The corrections for dust attenuation based on the IRX-β relation are highly uncertain and are still debated in the literature. Hence, rest-frame far-infrared (FIR) observations are necessary to constrain the dust-obscured com…
Characterizing the dust content of disk substructures in TW Hydrae
Huang, J.; Ribas, Á.; Carrasco-González, C. +4 more
Context. A key piece of information to understand the origin and role of protoplanetary disk substructures is their dust content. In particular, disk substructures associated with gas pressure bumps can work as dust traps, accumulating grains and reaching the necessary conditions to trigger the streaming instability.
Aims: In order to shed so…
Gaia Early Data Release 3. The Galactic anticentre
Prusti, T.; Mazeh, T.; Zucker, S. +417 more
Aims: We aim to demonstrate the scientific potential of the Gaia Early Data Release 3 (EDR3) for the study of different aspects of the Milky Way structure and evolution and we provide, at the same time, a description of several practical aspects of the data and examples of their usage.
Methods: We used astrometric positions, proper motio…
The CARMENES search for exoplanets around M dwarfs. Stellar atmospheric parameters of target stars with SteParSyn
Nagel, E.; Amado, P. J.; Caballero, J. A. +24 more
We determined effective temperatures, surface gravities, and metallicities for a sample of 343 M dwarfs observed with CARMENES, the double-channel, high-resolution spectrograph installed at the 3.5 m telescope at Calar Alto Observatory. We employed SteParSyn, a Bayesian spectral synthesis implementation particularly designed to infer the stellar a…
The VANDELS ESO public spectroscopic survey. Final data release of 2087 spectra and spectroscopic measurements
Maccagni, D.; Cimatti, A.; Elbaz, D. +94 more
VANDELS is an ESO Public Spectroscopic Survey designed to build a sample of high-signal-to-noise ratio, medium-resolution spectra of galaxies at redshifts between 1 and 6.5. Here we present the final Public Data Release of the VANDELS Survey, comprising 2087 redshift measurements. We provide a detailed description of sample selection, observations…
