How Well Can We Measure the Stellar Mass of a Galaxy: The Impact of the Assumed Star Formation History Model in SED Fitting
Conroy, Charlie; Johnson, Benjamin D.; Davé, Romeel +3 more
The primary method for inferring the stellar mass (M*) of a galaxy is through spectral energy distribution (SED) modeling. However, the technique rests on assumptions such as the galaxy star formation history (SFH) and dust attenuation law that can severely impact the accuracy of derived physical properties from SED modeling. Here we ex…
2SXPS: An Improved and Expanded Swift X-Ray Telescope Point-source Catalog
Cenko, S. B.; Tagliaferri, G.; Kennea, J. A. +8 more
We present the 2SXPS (Swift-XRT Point Source) catalog, containing 206,335 point sources detected by the Swift X-ray Telescope (XRT) in the 0.3-10 keV energy range. This catalog represents a significant improvement over 1SXPS, with double the sky coverage (now 3790 deg2), and several significant developments in source detection and class…
The MOSDEF survey: direct-method metallicities and ISM conditions at z ∼ 1.5-3.5
Barro, Guillermo; Siana, Brian; Shapley, Alice E. +14 more
We present detections of [O III] λ4363 and direct-method metallicities for star-forming galaxies at z = 1.7-3.6. We combine new measurements from the MOSFIRE Deep Evolution Field (MOSDEF) survey with literature sources to construct a sample of 18 galaxies with direct-method metallicities at z > 1, spanning 7.5 < 12+log(O/H) < 8.2 and log(…
A Volume-limited Sample of Cataclysmic Variables from Gaia DR2: Space Density and Population Properties
Knigge, C.; Hermes, J. J.; Gänsicke, B. T. +15 more
We present the first volume-limited sample of cataclysmic variables (CVs), selected using the accurate parallaxes provided by the second data release (DR2) of the European Space Agency Gaia space mission. The sample is composed of 42 CVs within 150 pc, including two new systems discovered using the Gaia data, and is $(77 \pm 10)$ per cent complete…
Axion and neutrino bounds improved with new calibrations of the tip of the red-giant branch using geometric distance determinations
Capozzi, Francesco; Raffelt, Georg
The brightness of the tip of the red-giant branch (TRGB) allows one to constrain novel energy losses that would lead to a larger core mass at helium ignition and, thus, to a brighter TRGB than expected by standard stellar models. The required absolute TRGB calibrations strongly improve with reliable geometric distances that have become available f…
The mineral diversity of Jezero crater: Evidence for possible lacustrine carbonates on Mars
Anderson, Ryan B.; Horgan, Briony H. N.; Dromart, Gilles +2 more
Noachian-aged Jezero crater is the only known location on Mars where clear orbital detections of carbonates are found in close proximity to clear fluvio-lacustrine features indicating the past presence of a paleolake; however, it is unclear whether or not the carbonates in Jezero are related to the lacustrine activity. This distinction is critical…
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…
