Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri
Gaia Collaboration, K. Weingrill, A. Mints +400
Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…
Gaia Focused Product Release: Asteroid orbital solution. Properties and assessment
Gaia Collaboration, P. David, F. Mignard +2
Context. We report the exploitation of a sample of epoch astrometry for 157 000 asteroids, the same object in the Gaia Data Release 3, extended over the time coverage planned for t…
Gaia Focused Product Release: A catalogue of sources around quasars to search for strongly lensed quasars
Gaia Collaboration, A. Krone-Martins, C. Ducourant +398
Context. Strongly lensed quasars are fundamental sources for cosmology. The Gaia space mission covers the entire sky with the unprecedented resolution of " in the optical, ma…
Gaia Focused Product Release: Radial velocity time series of long-period variables
Gaia Collaboration, M. Trabucchi, N. Mowlavi +403
The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocit…
Beyond Gaia DR3: Tracing the [/M]-[M/H] bimodality from the inner to the outer Milky Way disc with Gaia-RVS and convolutional neural networks
G. Guiglion, S. Nepal, C. Chiappini +17
In June 2022, Gaia DR3 has provided the astronomy community with about one million spectra from the Radial Velocity Spectrometer (RVS) covering the CaII triplet region. However, on…
The Close AGN Reference Survey (CARS): IFU survey data and the BH mass dependence of long-term AGN variability
B. Husemann, M. Singha, J. Scharwächter +19
[Abridged] AGN are thought to be intimately connected with their host galaxies through feeding and feedback processes. A spatially resolved multiwavelength survey is required to ma…
Various scenarios for the equatorward migration of sunspots
Detlef Elstner, Yori Fournier, Rainer Arlt
The profile of the differential rotation together with the sign of the alpha-effect determine the dynamo wave direction. In early models of the solar dynamo the dynamo wave often l…
Delayed Babcock-Leighton dynamos in the diffusion-dominated regime
Y. Fournier, R. Arlt, D. Elstner
Context. Solar dynamo models of Babcock-Leighton type typically assume the rise of magnetic flux tubes to be instantaneous. Solutions with high-magnetic-diffusivity have too short…
3D simulations of rising magnetic flux tubes in a compressible rotating interior: The effect of magnetic tension
Yori Fournier, Rainer Arlt, Udo Ziegler +1
Context: Long-term variability in solar cycles represents a challenging constraint for theoretical models. Mean-field Babcock-Leighton dynamos that consider non-instantaneous risin…
