The SPTpol Extended Cluster Survey
Sharon, K.; Gladders, M. D.; Ade, P. A. R. +135 more
We describe the observations and resultant galaxy cluster catalog from the 2770 deg2 SPTpol Extended Cluster Survey (SPT-ECS). Clusters are identified via the Sunyaev-Zel'dovich (SZ) effect and confirmed with a combination of archival and targeted follow-up data, making particular use of data from the Dark Energy Survey (DES). With inco…
The Spectrometer/Telescope for Imaging X-rays (STIX)
Krucker, Säm; Veronig, A. M.; Rodríguez-Pacheco, J. +86 more
Aims: The Spectrometer Telescope for Imaging X-rays (STIX) on Solar Orbiter is a hard X-ray imaging spectrometer, which covers the energy range from 4 to 150 keV. STIX observes hard X-ray bremsstrahlung emissions from solar flares and therefore provides diagnostics of the hottest (⪆10 MK) flare plasma while quantifying the location, spectrum,…
Hunting for open clusters in Gaia DR2: 582 new open clusters in the Galactic disc
Castro-Ginard, A.; Jordi, C.; Luri, X. +8 more
Context. Open clusters are key targets for studies of Galaxy structure and evolution, and stellar physics. Since the Gaia data release 2 (DR2), the discovery of undetected clusters has shown that previous surveys were incomplete.
Aims: Our aim is to exploit the Big Data capabilities of machine learning to detect new open clusters in Gaia DR2,…
The Gaia-Kepler Stellar Properties Catalog. II. Planet Radius Demographics as a Function of Stellar Mass and Age
van Saders, Jennifer L.; Huber, Daniel; Berger, Travis A. +2 more
Studies of exoplanet demographics require large samples and precise constraints on exoplanet host stars. Using the homogeneous Kepler stellar properties derived using the Gaia Data Release 2 by Berger et al., we recompute Kepler planet radii and incident fluxes and investigate their distributions with stellar mass and age. We measure the stellar m…
The ALPINE-ALMA [CII] survey. The nature, luminosity function, and star formation history of dusty galaxies up to z ≃ 6
Cimatti, A.; Pozzi, F.; Rodighiero, G. +30 more
Aims: We present the detailed characterisation of a sample of 56 sources serendipitously detected in ALMA band 7 as part of the ALMA Large Program to INvestigate CII at Early Times (ALPINE). These sources, detected in COSMOS and ECDFS, have been used to derive the total infrared luminosity function (LF) and to estimate the cosmic star formati…
Dust masses of young disks: constraining the initial solid reservoir for planet formation
Manara, Carlo F.; van Dishoeck, Ewine F.; Rosotti, Giovanni P. +7 more
Context. Recent years have seen building evidence that planet formation starts early, in the first ~0.5 Myr. Studying the dust masses available in young disks enables us to understand the origin of planetary systems given that mature disks are lacking the solid material necessary to reproduce the observed exoplanetary systems, especially the massi…
The Polarimetric and Helioseismic Imager on Solar Orbiter
Schmidt, W.; Woch, J.; Solanki, S. K. +121 more
Aims: This paper describes the Polarimetric and Helioseismic Imager on the Solar Orbiter mission (SO/PHI), the first magnetograph and helioseismology instrument to observe the Sun from outside the Sun-Earth line. It is the key instrument meant to address the top-level science question: How does the solar dynamo work and drive connections betw…
Discovery of a 2.8 s Pulsar in a 2 Day Orbit High-mass X-Ray Binary Powering the Ultraluminous X-Ray Source ULX-7 in M51
Salvaterra, R.; Haberl, F.; Tiengo, A. +26 more
We discovered 2.8 s pulsations in the X-ray emission of the ultraluminous X-ray source (ULX) M51 ULX-7 within the UNSEeN project, which was designed to hunt for new pulsating ULXs (PULXs) with XMM-Newton. The pulse shape is sinusoidal, and large variations of its amplitude were observed even within single exposures (pulsed fraction from less than …
From the bulge to the outer disc: StarHorse stellar parameters, distances, and extinctions for stars in APOGEE DR16 and other spectroscopic surveys
Schultheis, M.; Minniti, D.; Bizyaev, D. +27 more
We combine high-resolution spectroscopic data from APOGEE-2 survey Data Release 16 (DR16) with broad-band photometric data from several sources as well as parallaxes from Gaia Data Release 2 (DR2). Using the Bayesian isochrone-fitting code StarHorse, we derived the distances, extinctions, and astrophysical parameters for around 388 815 APOGEE star…
Can late dark energy transitions raise the Hubble constant?
Raveri, Marco; Hu, Wayne; Benevento, Giampaolo
Late times dark energy transitions at redshifts z ≪0.1 can raise the predicted value of the Hubble constant to the SH0ES value, 74.03 ±1.42 (km s-1 Mpc-1) or more, while providing an equally good fit as Λ CDM at 67.73 ±0.41 to higher redshift data, in particular from the cosmic microwave background and baryon acoustic oscilla…
