Figure 5 of Ding et al. 2023: A new transverse space velocity distribution of millisecond pulsars is revealed with high-precision astrometry of 15 millisecond pulsars, which shows a tentative multi-modal feature that may potentially resolve both the globular cluster retention problem and the Galactic Center gamma-ray excess problem.

Panels show snapshots at 1, 3, 5, 8 Myr after the time of first star formation. Molecular, atomic, and ionized gas phases are shown in blue-white, green-white, and red-orange, respectively. Magnetic fields are shown as lines and star particles are shown as spheres.

Artit’s impression of the outward propagating “heat-wave” of energy
Maser emission traces a heat-wave of accretion energy emanating from a rare high-mass protostellar accretion event. Contours show the first moment (intensity) while colour indicates the second moment (velocity) of the emission with respect to the systematic velocity of the high-mass protostar progenitor, G358-MM1. Data were obtained using imaging with the very long baseline interferometry (VLBI) technique.

The magnitude of Faraday rotation measures (RMs) in the jet of a nearby radio galaxy M87. RMs systematically increase with decreasing distance, which indicates that the jet is in the environment of stronger magnetic fields near the jet base.

This plot shows the dense-gas star-formation relationships (star formation rate versus the mass of dense-gas) for all samples observed in HCN J=4-3 line emission, including the MALATANG survey data used in this work.
Resolving the relation between dense-gas and star formation in galaxies
The baryonic (gas+stars) masses and the scale lengths of the stellar disks of morphological late-type galaxies follow a very tight power-law relation over 4 orders of magnitudes in mass. This scaling relation provides a benchmark constraint to galaxy formation models.

ALMA long baselines observations (~6 au) of a low-mass protostar TMC1A. The dust continuum emission in orange and integrated molecular lines 13CO (green) and C18O (blue) are shown. The molecular emission falls off steeply at 30 au because of optically thick dust emission caused by large (up to millimeter) dust grains.
