The Mass Relations between Supermassive Black Holes and Their Host Galaxies at 1 < z < 2 HST-WFC3
Kartaltepe, Jeyhan S.; Koekemoer, Anton M.; Treu, Tommaso +10 more
Correlations between the mass of a supermassive black hole (SMBH) and the properties of its host galaxy (e.g., total stellar mass M *, luminosity L host) suggest an evolutionary connection. A powerful test of a coevolution scenario is to measure the relations {{ \mathcal M }}BH}-L host and {{ \mathcal M …
The Energetic Particle Detector. Energetic particle instrument suite for the Solar Orbiter mission
Kulkarni, S. R.; Lario, D.; Wang, L. +96 more
After decades of observations of solar energetic particles from space-based observatories, relevant questions on particle injection, transport, and acceleration remain open. To address these scientific topics, accurate measurements of the particle properties in the inner heliosphere are needed. In this paper we describe the Energetic Particle Dete…
The stellar-to-halo mass relation over the past 12 Gyr. I. Standard ΛCDM model
Bolzonella, M.; Giocoli, C.; Marulli, F. +3 more
Aims: Understanding the link between the galaxy properties and the dark matter halos they reside in and their coevolution is a powerful tool for constraining the processes related to galaxy formation. In particular, the stellar-to-halo mass relation (SHMR) and its evolution throughout the history of the Universe provides insights on galaxy fo…
Public HARPS radial velocity database corrected for systematic errors
Trifonov, Trifon; Mazeh, Tsevi; Zechmeister, Mathias +3 more
Context. The High Accuracy Radial velocity Planet Searcher (HARPS) spectrograph has been mounted since 2003 at the ESO 3.6 m telescope in La Silla and provides state-of-the-art stellar radial velocity (RV) measurements with a precision down to ∼1 m s-1. The spectra are extracted with a dedicated data-reduction software (DRS), and the RV…
The Orbital Histories of Magellanic Satellites Using Gaia DR2 Proper Motions
van der Marel, Roeland P.; Gómez, Facundo A.; Weisz, Daniel R. +6 more
With the release of Gaia DR2, it is now possible to measure the proper motions (PMs) of the lowest-mass, ultrafaint satellite galaxies in the Milky Way's (MW) halo for the first time. Many of these faint satellites are posited to have been accreted as satellites of the Magellanic Clouds (MCs). Using their six-dimensional phase-space information, w…
Measuring Turbulent Motion in Planet-forming Disks with ALMA: A Detection around DM Tau and Nondetections around MWC 480 and V4046 Sgr
Hughes, A. Meredith; Wilner, David J.; Kóspál, Ágnes +6 more
Turbulence is a crucial factor in many models of planet formation, but it has only been directly constrained among a small number of planet-forming disks. Building on the upper limits on turbulence placed in disks around HD 163296 and TW Hya, we present ALMA CO J = 2-1 line observations at ∼0"3 (20-50 au) resolution and 80 ms-1 channel …
CARMENES input catalogue of M dwarfs. V. Luminosities, colours, and spectral energy distributions
Amado, P. J.; Caballero, J. A.; Reiners, A. +15 more
Context. The relevance of M dwarfs in the search for potentially habitable Earth-sized planets has grown significantly in the last years.
Aims: In our on-going effort to comprehensively and accurately characterise confirmed and potential planet-hosting M dwarfs, in particular for the CARMENES survey, we have carried out a comprehensive multi-…
Tracing the total molecular gas in galaxies: [CII] and the CO-dark gas
Ramambason, L.; Lebouteiller, V.; Madden, S. C. +11 more
Context. Molecular gas is a necessary fuel for star formation. The CO (1-0) transition is often used to deduce the total molecular hydrogen but is challenging to detect in low-metallicity galaxies in spite of the star formation taking place. In contrast, the [C II]λ158 µm is relatively bright, highlighting a potentially important reservoir o…
Probing cosmic isotropy with a new X-ray galaxy cluster sample through the LX-T scaling relation
Lovisari, L.; Pacaud, F.; Ramos-Ceja, M. E. +3 more
The isotropy of the late Universe and consequently of the X-ray galaxy cluster scaling relations is an assumption greatly used in astronomy. However, within the last decade, many studies have reported deviations from isotropy when using various cosmological probes; a definitive conclusion has yet to be made. New, effective and independent methods …
A new mass-loss rate prescription for red supergiants
Smith, Nathan; Gehrz, Robert D.; van Loon, Jacco Th +3 more
Evolutionary models have shown the substantial effect that strong mass-loss rates ( $\dot{M}$ s) can have on the fate of massive stars. Red supergiant (RSG) mass-loss is poorly understood theoretically, and so stellar models rely on purely empirical $\dot{M}$ -luminosity relations to calculate evolution. Empirical prescriptions usually scale with …
