Gaia Data Release 3. Summary of the content and survey properties
Prusti, T.; Mazeh, T.; Zucker, S. +453 more
Context. We present the third data release of the European Space Agency's Gaia mission, Gaia DR3. This release includes a large variety of new data products, notably a much expanded radial velocity survey and a very extensive astrophysical characterisation of Gaia sources.
Aims: We outline the content and the properties of Gaia DR3, providing…
Astrophysics with the Laser Interferometer Space Antenna
Wu, Kinwah; Haardt, Francesco; Ma, Chung-Pei +155 more
The Laser Interferometer Space Antenna (LISA) will be a transformative experiment for gravitational wave astronomy, and, as such, it will offer unique opportunities to address many key astrophysical questions in a completely novel way. The synergy with ground-based and space-born instruments in the electromagnetic domain, by enabling multi-messeng…
CEERS Key Paper. I. An Early Look into the First 500 Myr of Galaxy Formation with JWST
Papovich, Casey; Yang, Guang; Finkelstein, Steven L. +64 more
We present an investigation into the first 500 Myr of galaxy evolution from the Cosmic Evolution Early Release Science (CEERS) survey. CEERS, one of 13 JWST ERS programs, targets galaxy formation from z ~ 0.5 to >10 using several imaging and spectroscopic modes. We make use of the first epoch of CEERS NIRCam imaging, spanning 35.5 arcmin2<…
The evolution of the galaxy UV luminosity function at redshifts z ≃ 8 - 15 from deep JWST and ground-based near-infrared imaging
Moneti, A.; Bowler, R. A. A.; Cullen, F. +11 more
We reduce and analyse the available JWST ERO and ERS NIRCam imaging (SMACS0723, GLASS, CEERS) in combination with the latest deep ground-based near-infrared imaging in the COSMOS field (provided by UltraVISTA DR5) to produce a new measurement of the evolving galaxy UV luminosity function (LF) over the redshift range z = 8 - 15. This yields a new e…
Modules for Experiments in Stellar Astrophysics (MESA): Time-dependent Convection, Energy Conservation, Automatic Differentiation, and Infrastructure
Smolec, R.; Dotter, Aaron; Ball, Warrick H. +19 more
We update the capabilities of the open-knowledge software instrument Modules for Experiments in Stellar Astrophysics (MESA). The new auto_diff module implements automatic differentiation in MESA, an enabling capability that alleviates the need for hard-coded analytic expressions or finite-difference approximations. We significantly enhance the tre…
Gaia Data Release 3. Properties and validation of the radial velocities
Smith, M.; Gosset, E.; Caffau, E. +47 more
Context. Gaia Data Release 3 (Gaia DR3) contains the second release of the combined radial velocities. It is based on the spectra collected during the first 34 months of the nominal mission. The longer time baseline and the improvements of the pipeline made it possible to push the processing limit from GRVS = 12 in Gaia DR2 to GRVS…
Identification and properties of intense star-forming galaxies at redshifts z > 10
Maiolino, R.; Sun, F.; Egami, E. +53 more
Surveys with the James Webb Space Telescope (JWST) have discovered candidate galaxies in the first 400 Myr of cosmic time. Preliminary indications have suggested these candidate galaxies may be more massive and abundant than previously thought. However, without confirmed distances, their inferred properties remain uncertain. Here we identify four …
Gaia Data Release 3. Stellar multiplicity, a teaser for the hidden treasure
Prusti, T.; Mazeh, T.; Zucker, S. +448 more
Context. The Gaia DR3 catalogue contains, for the first time, about 800 000 solutions with either orbital elements or trend parameters for astrometric, spectroscopic, and eclipsing binaries, and combinations of these three.
Aims: With this paper, we aim to illustrate the huge potential of this large non-single-star catalogue.
Methods: Us…
CEERS Epoch 1 NIRCam Imaging: Reduction Methods and Simulations Enabling Early JWST Science Results
Papovich, Casey; Yang, Guang; Finkelstein, Steven L. +37 more
We present the data release and data reduction process for the Epoch 1 NIRCam observations for the Cosmic Evolution Early Release Science Survey (CEERS). These data consist of NIRCam imaging in six broadband filters (F115W, F150W, F200W, F277W, F356W and F444W) and one medium-band filter (F410M) over four pointings, obtained in parallel with prima…
Early Release Science of the exoplanet WASP-39b with JWST NIRSpec PRISM
Zhang, X.; Heng, K.; May, E. M. +91 more
Transmission spectroscopy1-3 of exoplanets has revealed signatures of water vapour, aerosols and alkali metals in a few dozen exoplanet atmospheres4,5. However, these previous inferences with the Hubble and Spitzer Space Telescopes were hindered by the observations' relatively narrow wavelength range and spectral resolving po…
