Rotation Velocity of the Milky Way Galaxy Based on VLBI Astrometry

Journal of Physics, Conference Series
The galactic rotation curve is an essential tool for understanding the dynamics, evolution, and formation of the Milky Way galaxy. We can study the mass distribution of the galaxy via the rotation curve.

Turbulence statistics of H i clouds entrained in the Milky Way’s nuclear wind [PDF]

Monthly notices of the Royal Astronomical Society
The interstellar medium (ISM) is ubiquitously turbulent across many physically distinct environments within the Galaxy. Turbulence is key in controlling the structure and dynamics of the ISM, regulating star formation, and transporting metals within ...

Structure and Dynamics of the Milky Way: The Evolving Picture

, 2010
From the inception of radio astronomy, the study of the Interstellar Medium has been both aided and frustrated by one fact: we are right within it! Our embedded perspective is favourable to observing kinematic and structural details that are likely to remain inaccessible in external galaxies for some time, but not so to gaining a birdseye view of our ...

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

On the Corotation of Milky Way Satellites: LMC-mass Satellites Induce Apparent Motions in Outer Halo Tracers

The Astrophysical Journal
Understanding the physical mechanism behind the formation of a corotating thin plane of satellite galaxies, like the one observed around the Milky Way (MW), has been challenging.

Cosmological implications of the Gaia Milky Way declining rotation curve [PDF]

Astronomy & Astrophysics
Although the existence of dark matter has been widely acknowledged in the cosmology community, its nature remains unknown despite decades of research. This calls into questions its very existence.

The C‐terminal truncated splicing variant of NK1R negatively modulates substance P‐stimulated NK1R signaling

FEBS Open Bio, EarlyView.
The neurokinin 1 receptor exists as full‐length (NK1L) and C‐terminally truncated (NK1S) splice variants. We show that NK1S heterodimerizes with NK1L, impairing Gαq coupling and Ca2+ mobilization while enhancing β‐arrestin1 recruitment. NK1S suppresses substance P‐driven gene expression and cell migration, revealing NK1S as an endogenous biased ...

The Orbital Eccentricities of Planets in the Kinematic Thin and Thick Galactic Disks

The Astronomical Journal
The orbital eccentricity distribution of exoplanets is shaped by a combination of dynamical processes, reflecting both formation conditions and long-term evolution.

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

FEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...

The Age–Thickness Relation as a Tracer of the Merger History of Disk Galaxies

The Astrophysical Journal
In the hierarchical framework of galaxy formation, disk galaxies are shaped by a sequence of mergers and interactions, yet reconstructing this history from observations remains challenging.
