Populating the brown dwarf and stellar boundary: Five stars with transiting companions near the hydrogen-burning mass limit
Henning, Thomas; Triaud, Amaury H. M. J.; Latham, David W. +53 more
We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exoplanet Survey Satellite (TESS) as TESS objects of interest (TOIs): TOI-148, TOI-587, TOI-681, TOI-746, and TOI-1213. Using TESS and ground-based photometry as well as radia…
The ASTRODEEP-GS43 catalogue: New photometry and redshifts for the CANDELS GOODS-South field
Elbaz, D.; Castellano, M.; Pentericci, L. +17 more
Context. We present ASTRODEEP-GS43, a new multi-wavelength photometric catalogue of the GOODS-South field, which builds and improves upon the previously released CANDELS catalogue.
Aims: We provide photometric fluxes and corresponding uncertainties in 43 optical and infrared bands (25 wide and 18 medium filters), as well as the photometric re…
Distance of Hi-GAL sources
Zavagno, A.; Elia, D.; Pezzuto, S. +18 more
Aims: Distances are key to determining the physical properties of sources. In the Galaxy, large (> 10 000) homogeneous samples of sources for which distance are available, covering the whole Galactic distance range, are still missing. Here we present a catalog of velocity and distance for a large sample (> 100 000) of Hi-GAL compact sou…
Low-frequency monitoring of flare star binary CR Draconis: long-term electron-cyclotron maser emission
Ray, T. P.; Callingham, J. R.; Shimwell, T. W. +12 more
Recently detected coherent low-frequency radio emission from M dwarf systems shares phenomenological similarities with emission produced by magnetospheric processes from the gas giant planets of our Solar System. Such beamed electron-cyclotron maser emission can be driven by a star-planet interaction or a breakdown in co-rotation between a rotatin…
Gas phase Elemental abundances in Molecular cloudS (GEMS). IV. Observational results and statistical trends
Roueff, E.; Kirk, J.; Ward-Thompson, D. +33 more
Gas phase Elemental abundances in Molecular CloudS (GEMS) is an IRAM 30 m Large Program designed to provide estimates of the S, C, N, and O depletions and gas ionization degree, X(e−), in a selected set of star-forming filaments of Taurus, Perseus, and Orion. Our immediate goal is to build up a complete and large database of molecular a…
The emergence of passive galaxies in the early Universe
Magnelli, B.; Castellano, M.; Pentericci, L. +10 more
The emergence of passive galaxies in the early Universe results from the delicate interplay among the different physical processes responsible for their rapid assembly and the abrupt shut-down of their star formation activity. Investigating the individual properties and demographics of early passive galaxies improves our understanding of these mec…
COALAS. I. ATCA CO(1-0) survey and luminosity function in the Spiderweb protocluster at z = 2.16
Thomson, A. P.; Dannerbauer, H.; Seymour, N. +25 more
We report a detailed CO(1−0) survey of a galaxy protocluster field at z = 2.16, based on 475 h of observations with the Australia Telescope Compact Array. We constructed a large mosaic of 13 individual pointings, covering an area of 21 arcmin2 and ±6500 km s−1 range in velocity. We obtained a robust sample of 46 CO(1−0) detec…
AT 2019avd: a novel addition to the diverse population of nuclear transients
Sollerman, J.; Rusholme, B.; Liu, Z. +29 more
We report on SRG/eROSITA, ZTF, ASAS-SN, Las Cumbres, NEOWISE-R, and Swift XRT/UVOT observations of the unique ongoing event AT 2019avd, located in the nucleus of a previously inactive galaxy at z = 0.029. eROSITA first observed AT 2019avd on 2020-04-28 during its first all sky survey, when it was detected as an ultra-soft X-ray source (kT ~ 85 eV)…
Discovery of a directly imaged planet to the young solar analog YSES 2
Mugrauer, Markus; Ginski, Christian; Kenworthy, Matthew A. +8 more
Context. To understand the origin and formation pathway of wide-orbit gas giant planets, it is necessary to expand the limited sample of these objects. The mass of exoplanets derived with spectrophotometry, however, varies strongly as a function of the age of the system and the mass of the primary star.
Aims: By selecting stars with similar a…
The X-CLASS survey: A catalogue of 1646 X-ray-selected galaxy clusters up to z ∼ 1.5
Altieri, B.; Valtchanov, I.; Pierre, M. +25 more
Context. Cosmological probes based on galaxy clusters rely on cluster number counts and large-scale structure information. X-ray cluster surveys are well suited for this purpose because they are far less affected by projection effects than optical surveys, and cluster properties can be predicted with good accuracy.
Aims: The XMM Cluster Archi…
