Dark matter local density determination: recent observations and future prospects
Widmark, A.; de Salas, Pablo F.
This report summarises progress made in estimating the local density of dark matter (ρDM,⊙), a quantity that is especially important for dark matter direct detection experiments. We outline and compare the most common methods to estimate ρDM,⊙ and the results from recent studies, including those that have benefited from the o…
Water in star-forming regions: physics and chemistry from clouds to disks as probed by Herschel spectroscopy
de Graauw, Th.; Liseau, R.; Braine, J. +50 more
Context. Water is a key molecule in the physics and chemistry of star and planet formation, but it is difficult to observe from Earth. The Herschel Space Observatory provided unprecedented sensitivity as well as spatial and spectral resolution to study water. The Water In Star-forming regions with Herschel (WISH) key program was designed to observ…
Atmospheric Rossiter-McLaughlin effect and transmission spectroscopy of WASP-121b with ESPRESSO
Bouchy, F.; Rebolo, R.; Pallé, E. +41 more
Context. Ultra-hot Jupiters are excellent laboratories for the study of exoplanetary atmospheres. WASP-121b is one of the most studied; many recent analyses of its atmosphere report interesting features at different wavelength ranges.
Aims: In this paper we analyze one transit of WASP-121b acquired with the high-resolution spectrograph ESPRES…
Extreme-UV quiet Sun brightenings observed by the Solar Orbiter/EUI
Haberreiter, M.; Mierla, M.; Zhukov, A. N. +25 more
Context. The heating of the solar corona by small heating events requires an increasing number of such events at progressively smaller scales, with the bulk of the heating occurring at scales that are currently unresolved.
Aims: The goal of this work is to study the smallest brightening events observed in the extreme-UV quiet Sun.

Gaia Early Data Release 3. Structure and properties of the Magellanic Clouds
Prusti, T.; Mazeh, T.; Zucker, S. +417 more
Context. This work is part of the Gaia Data Processing and Analysis Consortium papers published with the Gaia Early Data Release 3 (EDR3). It is one of the demonstration papers aiming to highlight the improvements and quality of the newly published data by applying them to a scientific case.
Aims: We use the Gaia EDR3 data to study the struct…
Atacama Cosmology Telescope: Modeling the gas thermodynamics in BOSS CMASS galaxies from kinematic and thermal Sunyaev-Zel'dovich measurements
Hilton, Matt; Sifón, Cristóbal; Battaglia, Nicholas +52 more
The thermal and kinematic Sunyaev-Zel'dovich effects (tSZ, kSZ) probe the thermodynamic properties of the circumgalactic and intracluster medium (CGM and ICM) of galaxies, groups, and clusters, since they are proportional, respectively, to the integrated electron pressure and momentum along the line of sight. We present constraints on the gas ther…
An atlas of MUSE observations towards twelve massive lensing clusters
Bacon, Roland; Carton, David; Bouché, Nicolas +24 more
Context. Spectroscopic surveys of massive galaxy clusters reveal the properties of faint background galaxies thanks to the magnification provided by strong gravitational lensing.
Aims: We present a systematic analysis of integral-field-spectroscopy observations of 12 massive clusters, conducted with the Multi Unit Spectroscopic Explorer (MUSE…
LOFAR observations of galaxy clusters in HETDEX. Extraction and self-calibration of individual LOFAR targets
Di Gennaro, G.; Brunetti, G.; Rossetti, M. +20 more
Diffuse cluster radio sources, in the form of radio halos and relics, reveal the presence of cosmic rays and magnetic fields in the intracluster medium (ICM). These cosmic rays are thought to be (re)accelerated through the ICM turbulence and shock waves generated by cluster merger events. Here we characterize the presence of diffuse radio emission…
New Insights into Classical Novae
Chomiuk, Laura; Shen, Ken J.; Metzger, Brian D.
We survey our understanding of classical novae-nonterminal, thermonuclear eruptions on the surfaces of white dwarfs in binary systems. The recent and unexpected discovery of GeV gamma rays from Galactic novae has highlighted the complexity of novae and their value as laboratories for studying shocks and particle acceleration. We review half a cent…
The completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: large-scale structure catalogues and measurement of the isotropic BAO between redshift 0.6 and 1.1 for the Emission Line Galaxy Sample
Myers, Adam D.; Brownstein, Joel R.; Schlegel, David J. +37 more
We present the Emission Line Galaxy (ELG) sample of the extended Baryon Oscillation Spectroscopic Survey from the Sloan Digital Sky Survey IV Data Release 16. We describe the observations and redshift measurement for the 269 243 observed ELG spectra, and then present the large-scale structure catalogues, used for the cosmological analysis, and mad…
