The phase spiral in Gaia DR3
T. Antoja, P. Ramos, B. García-Conde +3
We aim to study the phase spiral in the Milky Way (MW) with Gaia DR3. We used an edge detection algorithm to find the border of the phase spiral, allowing us to robustly quantify i…
Gaia Data Release 3: Gaia scan-angle dependent signals and spurious periods
B. Holl, C. Fabricius, J. Portell +23
Context: Gaia DR3 time series data may contain spurious signals related to the time-dependent scan angle. Aims: We aim to explain the origin of scan-angle dependent signals and how…
Tidally induced spiral arm wraps encoded in phase space
T. Antoja, P. Ramos, F. López-Guitart +3
We study the dynamics of tidally induced spiral arms in our Galaxy in the context of its encounters with Sagittarius. We built toy models of the interaction between a host and a sa…
Gaia Early Data Release 3: Structure and properties of the Magellanic Clouds
Gaia Collaboration, X. Luri, L. Chemin +417
We compare the Gaia DR2 and Gaia EDR3 performances in the study of the Magellanic Clouds and show the clear improvements in precision and accuracy in the new release. We also show…
Gaia Early Data Release 3: The Galactic anticentre
Gaia Collaboration, T. Antoja, P. McMillan +417
We aim to demonstrate the scientific potential of the Gaia Early Data Release 3 (EDR3) for the study of the Milky Way structure and evolution. We used astrometric positions, proper…
Gaia Early Data Release 3. Building the Gaia DR3 source list -- Cross-match of Gaia observations
F. Torra, J. Castañeda, C. Fabricius +12
The Gaia Early Data Release 3 (Gaia EDR3) contains results derived from 78 billion individual field-of-view transits of 2.5 billion sources collected by the European Space Agency's…
Gaia Early Data Release 3: The astrometric solution
L. Lindegren, S. A. Klioner, J. Hernández +94
Gaia Early Data Release 3 (Gaia EDR3) contains results for 1.812 billion sources in the magnitude range G = 3 to 21 based on observations collected by the European Space Agency Gai…
Gaia Early Data Release 3: The Gaia Catalogue of Nearby Stars
Gaia Collaboration, R. L. Smart, L. M. Sarro +420
We produce a clean and well-characterised catalogue of objects within 100\,pc of the Sun from the \G\ Early Data Release 3. We characterise the catalogue through comparisons to the…
Gaia Early Data Release 3: Acceleration of the solar system from Gaia astrometry
Gaia Collaboration, S. A. Klioner, F. Mignard +414
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-quali…
Faraday Rotation Measure Synthesis of intermediate redshift quasars as a probe of intervening matter
Kwang Seong Kim, Simon J. Lilly, Francesco Miniati +4
There is evidence that magnetized material along the line of sight to distant quasars is detectable in the polarization properties of the background sources. The polarization prope…
The dust content of damped Lyman-alpha systems in the Sloan Digital Sky Survey
Michael T. Murphy, Martin L. Bernet
The dust-content of damped Lyman-alpha systems (DLAs) is an important observable for understanding their origin and the neutral gas reservoirs of galaxies. While the average colour…
The extent of magnetic fields around galaxies out to z ~ 1
M. L. Bernet, F. Miniati, S. J. Lilly
Radio quasar sightlines with strong MgII absorption lines display statistically enhanced Faraday Rotation Measures (RM) indicating the presence of additional magneto-active plasma…
The interpretation of Rotation Measures in the presence of inhomogeneous foreground screens
M. L. Bernet, F. Miniati, S. J. Lilly
We analyze the redshift evolution of the Rotation Measure (RM) in Taylor et al. (2009) dataset, which is based on NVSS radio data at 21 cm, and compare with results from our previo…
MgII absorption systems with W_0 > 0.1 Åfor a radio selected sample of 77 QSOs and their associated magnetic fields at high redshifts
M. L. Bernet, F. Miniati, S. J. Lilly
We present a catalogue of MgII absorption systems obtained from high resolution UVES/VLT data of 77 QSOs in the redshift range 0.6 < z < 2.0, and down to an equivalent width W_0 >…
Strong magnetic fields in normal galaxies at high redshifts
Martin L. Bernet, Francesco Miniati, Simon J. Lilly +2
The origin and growth of magnetic fields in galaxies is still something of an enigma. It is generally assumed that seed fields are amplified over time through the dynamo effect, bu…
