Gaia Data Release 3 Summary of the variability processing and analysis

Context. Gaia has been in operations since 2014, and two full data releases (DR) have been delivered so far: DR1 in 2016 and DR2 in 2018. The third Gaia data release expands from the early data release (EDR3) in 2020, which contained the five-parameter ast ...

Gaia Data Release 3: The extragalactic content

Mária Süveges, Pablo Jose Fernandez Marcos, Shuangqing Liao, Richard Irving Anderson

The Gaia Galactic survey mission is designed and optimized to obtain astrometry, photometry, and spectroscopy of nearly two billion stars in our Galaxy. Yet as an all-sky multi-epoch survey, Gaia also observes several million extragalactic objects down to ...

Exploring and mapping the diffuse interstellar band at 862nm

Mária Süveges, Pablo Jose Fernandez Marcos, Shuangqing Liao, Richard Irving Anderson

Context. Di ffuse interstellar bands (DIBs) are common interstellar absorption features in spectroscopic observations but their origins remain unclear. DIBs play an important role in the life cycle of the interstellar medium (ISM) and can also be used to t ...

Networks with correlated edge processes

Mária Süveges, Sofia Charlotta Olhede

This article proposes methods to model non-stationary temporal graph processes motivated by a hospital interaction data set. This corresponds to modelling the observation of edge variables indicating interactions between pairs of nodes exhibiting dependenc ...

Gaia Early Data Release 3 The Galactic anticentre

Mária Süveges

Aims. We aim to demonstrate the scientific potential of the Gaia Early Data Release 3 (EDR3) for the study of different aspects of the Milky Way structure and evolution and we provide, at the same time, a description of several practical aspects of the dat ...

Gaia Early Data Release 3 The Gaia Catalogue of Nearby Stars

Mária Süveges, Javier García Hernández, Jean-Paul Richard Kneib

Aims. We produce a clean and well-characterised catalogue of objects within 100 pc of the Sun from the Gaia Early Data Release 3. We characterise the catalogue through comparisons to the full data release, external catalogues, and simulations. We carry out ...

Gaia Early Data Release 3 Summary of the contents and survey properties

Mária Süveges

Context. We present the early installment of the third Gaia data release, Gaia EDR3, consisting of astrometry and photometry for 1.8 billion sources brighter than magnitude 21, complemented with the list of radial velocities from Gaia DR2. ...

Gaia Early Data Release 3 Acceleration of the Solar System from Gaia astrometry

Mária Süveges

Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quality five-parameter astrometric solutions. ...

Gaia Early Data Release 3 Structure and properties of the Magellanic Clouds

Mária Süveges

Context. This work is part of the Gaia Data Processing and Analysis Consortium papers published with the Gaia Early Data Release 3 (EDR3). It is one of the demonstration papers aiming to highlight the improvements and quality of the newly published data by ...

Gaia Data Release 2 Summary of the variability processing and analysis results

Stephan Morgenthaler, Mária Süveges, Lorenzo Diana

Context. The Gaia Data Release 2 (DR2) contains more than half a million sources that are identified as variable stars. ...

A case study of a "Dragon-King": The 1999 Venezuelan catastrophe

Anthony Christopher Davison, Mária Süveges

We describe a failure of standard extremal models to account for a catastrophic rainfall event in the coastal regions of Venezuela on 14-16 December 1999, due both to inaccurate tail modelling and to an inadequate treatment of clusters of rare events. We i ...

Model misspecification in peaks over threshold analysis

Anthony Christopher Davison, Mária Süveges

Classical peaks over threshold analysis is widely used for statistical modeling of sample extremes, and can be supplemented by a model for the sizes of clusters of exceedances. Under mild conditions a compound Poisson process model allows the estimation of ...

Statistical analysis of clusters of extreme events

Mária Süveges

The thesis is a contribution to extreme-value statistics, more precisely to the estimation of clustering characteristics of extreme values. One summary measure of the tendency to form groups is the inverse average cluster size. In extreme-value context, th ...

Likelihood estimation of the extremal index

Mária Süveges

The article develops the approach of Ferro and Segers (2003) to the estimation of the extremal index, and proposes the use of a new variable decreasing the bias of the likelihood based on the point process character of the exceedances. Two estimators are d ...
