CLASH-VLT: Abell S1063. Cluster assembly history and spectroscopic catalogue
Rodighiero, G.; Demarco, R.; Gruen, D. +31 more
Context. The processes responsible for galaxy evolution in different environments as a function of galaxy mass remain heavily debated. Rich galaxy clusters are ideal laboratories in which to distinguish the role of environmental versus mass quenching because they consist of a full range of galaxies and environments.
Aims: Using the CLASH-VLT …
A major asymmetric ice trap in a planet-forming disk. II. Prominent SO and SO2 pointing to C/O < 1
Booth, Alice S.; van Dishoeck, Ewine F.; Leemker, Margot +2 more
Gas-phase sulphur-bearing volatiles appear to be severely depleted in protoplanetary disks. The detection of CS and the non-detections of SO and SO2 in many disks have shown that the gas in the warm molecular layer, where giant planets accrete their atmospheres, has a high C/O ratio. In this Letter, we report the detection of SO and SO<…
Chamaeleon DANCe. Revisiting the stellar populations of Chamaeleon I and Chamaeleon II with Gaia-DR2 data
Bertin, E.; Miret-Roig, N.; Bouy, H. +6 more
Context. Chamaeleon is the southernmost low-mass star-forming complex within 200 pc from the Sun. Its stellar population has been extensively studied in the past, but the current census of the stellar content is not complete yet and deserves further investigation.
Aims: We take advantage of the second data release of the Gaia space mission to…
An ultra-short-period transiting super-Earth orbiting the M3 dwarf TOI-1685
Tamura, M.; Amado, P. J.; Caballero, J. A. +51 more
Dynamical histories of planetary systems, as well as the atmospheric evolution of highly irradiated planets, can be studied by characterizing the ultra-short-period planet population, which the TESS mission is particularly well suited to discover. Here, we report on the follow-up of a transit signal detected in the TESS sector 19 photometric time …
ALMA chemical survey of disk-outflow sources in Taurus (ALMA-DOT). V. Sample, overview, and demography of disk molecular emission
Podio, L.; Bacciotti, F.; Fedele, D. +9 more
We present an overview of the ALMA chemical survey of disk-outflow sources in Taurus (ALMA-DOT), a campaign devoted to the characterization of the molecular emission from partly embedded young stars. The project is aimed at attaining a better understanding of the gaseous products delivered to planets by means of high-resolution maps of the assorte…
SUPER. IV. CO(J = 3-2) properties of active galactic nucleus hosts at cosmic noon revealed by ALMA
Salvato, M.; Zanella, A.; Saintonge, A. +23 more
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
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
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
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?
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…
