VLBI astrometry gives a 20.2 kpc distance and 872 pc height for G040.96+02.48, confirming a warp in the Extreme Outer Galaxy with unusual outward motion.
Serendipitous discovery of a bound nine-member protostellar system in NGC 6334-43 formed by filament fragmentation, with outflows from two sources and virial masses derived for three cores.
Discovery of extended GeV gamma-ray emission from AFGL 490, with the protostellar jet identified as the likely particle accelerator rather than stellar winds.
Young giant stars reveal a flaring Milky Way disc with 3.5 kpc radial scale and extended spiral arms including a curved Perseus segment and a new Scutum-associated feature.
HONKAI identifies 193 dense cores in 16 clumps within three IRDCs, finding most have virial ratios >1 but mass-size relations below the massive star formation threshold and a steeper high-mass CMF slope.
Revised radial-velocity response model including V_R,sin and V_R,cos applied to Milky Way kinematic data constrains spiral pitch angle to ~10°, density contrast 5-18%, and pattern speed 10-20 km/s/kpc.
New catalogue of 1327 extended Galactic HII regions from SMGPS 1.3 GHz data with distances, N_Ly fluxes, spectral types B3-O4, and reported correlations between radius, density, and ionizing luminosity.
Analysis of 3161 molecular clouds reveals oblate shapes aligned with the galactic plane, a flatter velocity dispersion-size relation than Larson's law, strong mass-size correlation, and that 12CO traces diffuse turbulent gas while C18O traces gravity-dominated regions.
Supervised ML models achieve R^2 > 0.90 when mapping multi-frequency radio data to 0.1-10 GeV gamma-ray intensity and attribute high-frequency radio bands to hadronic processes and low-frequency bands to leptonic processes.
C-rich AGB stars trace the Galactic warp with larger amplitudes than Cepheids at intermediate ages of about 1 Gyr.
Catalog of 1,573 molecular clouds with robust distances from 150 to 3000 pc determined by matching CO intensity maps to dust extinction maps, 90% measured for the first time with ~20% statistical and ~10% systematic uncertainties.
New CO(2-1) observations of 112 clumps in outer Galactic clouds (14-23 kpc) yield velocity dispersion-size and mass-size power laws plus a declining virial parameter trend indicating most clumps are gravitationally unbound.
G352 is an unbound proto-OB association of young stars along a 150-pc filament at 1670 pc whose kinematics and steep pitch angle are inconsistent with galactic spiral structure.
NE2025 refits the thick disk, thin disk, and spiral arms of the NE2001 model and adds refined clumps, delivering 20 times better median pulsar distance accuracy and 100 percent better scattering predictions than NE2001.
Recalibration of the Hα surface brightness-radius relation with Gaia DR3 parallaxes yields new distances for 1130 planetary nebulae and shows breaks in the Milky Way oxygen radial gradient near the solar radius.
Maser emissions act as cosmic rulers for astrometric measurements of astronomical sources from protostellar scales to galactic distances, with SKA-Mid enabling expanded multi-species observations.
Proposes SKA surveys for a census of galactic magnetic fields from low to high redshift using polarimetry, RM grids, and lensed quasars to constrain dynamo models.
Perspective outlining how SKA-VLBI will map the Milky Way's full spiral structure and constrain Galactic parameters using high-precision maser astrometry.
The chapter proposes SKA spectroscopic surveys of the inner and outer Milky Way using OH, CH, radio recombination lines, and H2CO to study molecular cloud formation, ionized gas properties, and CO-dark molecular gas.
