In a cosmological setting, the disk of a galaxy is expected to continuously experience gravitational torques and perturbations from a variety of sources, which can cause the disk to wobble, flare and warp 1 , 2 . Specifically, the study of galactic warps and their dynamic nature could reveal key information on the formation history of galaxies and the mass distribution of their haloes. Our Milky Way presents a unique case study for galactic warps, thanks to detailed knowledge of its stellar… 

Exploring the Galactic Warp through Asymmetries in the Kinematics of the Galactic Disk

Previous analyses of large databases of Milky Way stars have revealed the stellar disk of our Galaxy to be warped and that this imparts a strong signature on the kinematics of stars beyond the solar

Three-Dimensional Kinematics of Classical Cepheids

—A linear Ogorodnikov–Milne model is applied to study the three-dimensional kinematics of classical Cepheids in the Milky Way. A sample of 832 classical Cepheids from Mr´oz et al. (2019) with

Mapping the Galactic Disk with the LAMOST and Gaia Red Clump Sample. VI. Evidence for the Long-lived Nonsteady Warp of Nongravitational Scenarios

By combining LAMOST DR4 and Gaia DR2 common red clump stars with age and proper motion, we analyze the amplitude evolution of the stellar warp independently of any assumption with a simple model. The

Evidence of a Dark Matter that Is Not an Exotic Matter: WLM’s Case

A recent article reports new observations of the gaseous content of Wolf-Lundmark-Melotte (WLM), an archetype of isolated, gas-rich field dwarf galaxies in the Local Universe, which presents an

To investigate the role of magnetic fields in the evolution of the interstellar medium, formation and evolution of molecular clouds, and ultimately the formation of stars, their three-dimensional

Snails across Scales: Local and Global Phase-mixing Structures as Probes of the Past and Future Milky Way

Signatures of vertical disequilibrium have been observed across the Milky Way’s (MW’s) disk. These signatures manifest locally as unmixed phase spirals in z–v z space (“snails-in-phase”), and

3D Parameter Maps of Red Clump Stars in the Milky Way: Absolute Magnitudes and Intrinsic Colors

Red clump stars (RCs) are useful tracers of distances, extinction, chemical abundances, and Galactic structures and kinematics. Accurate estimation of RC parameters—absolute magnitude and intrinsic

The structure of the Milky Way based on unWISE 3.4 μm integrated photometry

We present a detailed analysis of the Galaxy structure using an unWISE wide-field image at $3.4\,\mu$m. We perform a 3D photometric decomposition of the Milky Way taking into account (i) the

A three-dimensional map of the Milky Way using classical Cepheid variable stars

A map of the Milky Way in three dimensions, based on the positions and distances of thousands of classical Cepheid variable stars, shows the structure of the Galaxy’s young stellar population and allows us to constrain the warped shape of the galactic disc.

The Gaia reference frame for bright sources examined using VLBI observations of radio stars (Corrigendum)

Context. Positions and proper motions of Gaia sources are expressed in a reference frame that ideally should be non-rotating relative to distant extragalactic objects, coincident with the

RULES OF BEHAVIOR FOR GALACTIC WARPS

An analysis conducted for 12 galaxies with extended, warped H I disks in a variety of reference frames has led to the formulation of clear empirical criteria for galactic warp behavior. In view of

The Galactic warp as seen from 2MASS survey

The 2MASS survey is used to trace the shape of the external Galaxy where an asymmetric warp is detected. We use the Besancon Galaxy model to quantify the parameters of the stellar warp in the outer

The gravitational force field of the Galaxy measured from the kinematics of RR Lyrae in Gaia

From a sample of 15651 RR Lyrae with accurate proper motions in Gaia DR2, we measure the azimuthally averaged kinematics of the inner stellar halo between 1.5  and 20  kpc from the Galactic centre.
