SUPER. IV. CO(J = 3-2) properties of active galactic nucleus hosts at cosmic noon revealed by ALMA
DOI: 10.1051/0004-6361/202039270 Bibcode: 2021A&A...646A..96C

Feedback from active galactic nuclei (AGN) is thought to be key in shaping the life cycle of their host galaxies by regulating star-formation activity. Therefore, to understand the impact of AGN on star formation, it is essential to trace the molecular gas out of which stars form. In this paper we present the first systematic study of the CO prope…

Spectroscopic observations of PHz G237.01+42.50: A galaxy protocluster at z = 2.16 in the Cosmos field
DOI: 10.1051/0004-6361/202140612 Bibcode: 2021A&A...654A.121P

Dole, H.; Lagache, G.; Montier, L. +10 more

The Planck satellite has identified more than 2000 protocluster candidates with extreme star formation rates (SFRs). Here, we present the spectroscopic identification of a Planck-selected protocluster located in the Cosmos field, PHz G237.01+42.50. PHz G237.01+42.50 contains a galaxy overdensity of 31 spectroscopically identified galaxies at z ≃ 2…

Evidence for disequilibrium chemistry from vertical mixing in hot Jupiter atmospheres. A comprehensive survey of transiting close-in gas giant exoplanets with warm-Spitzer/IRAC
DOI: 10.1051/0004-6361/202039708 Bibcode: 2021A&A...648A.127B

Deming, Drake; Burrows, Adam; Fortney, Jonathan J. +10 more


Aims: We present a large atmospheric study of 49 gas giant exoplanets using infrared transmission photometry with Spitzer/IRAC at 3.6 and 4.5 µm.
Methods: We uniformly analyze 70 photometric light curves of 33 transiting planets using our custom pipeline, which implements pixel level decorrelation. Augmenting our sample with 16 pre…

Fitting spectral energy distributions of FMOS-COSMOS emission-line galaxies at z ∼ 1.6: Star formation rates, dust attenuation, and [OIII]λ5007 emission-line luminosities
DOI: 10.1051/0004-6361/202140890 Bibcode: 2021A&A...654A.153V

Buat, V.; Boquien, M.; Burgarella, D. +2 more

We perform a spectral energy distribution fitting analysis on a COSMOS photometric sample covering the ultra-violet up to the far-infrared wavelengths and including emission lines from the Fiber Multi-Object Spectrograph survey. The sample consists of 182 objects with Hα and [OIII]λ5007 emission line measurements lying in a redshift range of 1.40 …

Does NGC 6397 contain an intermediate-mass black hole or a more diffuse inner subcluster?
DOI: 10.1051/0004-6361/202039650 Bibcode: 2021A&A...646A..63V

Mamon, Gary A.; Vitral, Eduardo

We analyze proper motions from the Hubble Space Telescope (HST) and the second Gaia data release along with line-of-sight velocities from the MUSE spectrograph to detect imprints of an intermediate-mass black hole (IMBH) in the center of the nearby, core-collapsed, globular cluster NGC 6397. For this, we use the new MAMPOSST-PM Bayesian mass-model…

Populating the brown dwarf and stellar boundary: Five stars with transiting companions near the hydrogen-burning mass limit
DOI: 10.1051/0004-6361/202141145 Bibcode: 2021A&A...652A.127G

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
DOI: 10.1051/0004-6361/202140310 Bibcode: 2021A&A...649A..22M

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
DOI: 10.1051/0004-6361/202038956 Bibcode: 2021A&A...646A..74M

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
DOI: 10.1051/0004-6361/202039144 Bibcode: 2021A&A...648A..13C

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) 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…
