Defines path-signature descriptors for spectral line profiles and shows they enable unsupervised clustering of MaNGA Hα spaxels into spatially coherent classes whose stacked spectra recover large-scale velocity patterns.

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.
Survey detects 88 new HH objects in Serpens-Aquila Rift and maps five star-forming clouds at 250-700 pc, positioning HH outflows as indicators of active star formation sites.
ALMA Cycle 6 data on Aquila dense cores identifies two starless sources and scale-dependent increases in multiplicity, consistent with turbulent core collapse simulations predicting 1.19 starless detections.
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.
Gaia21bja is identified as a pre-main sequence star with quasi-periodic bursts, showing spectral features and a 5.5-6 times higher accretion rate during outbursts that place it in the periodic category of outbursting YSOs.
Observational study of G12.79+0.43 identifies YSOs and HII regions powered by B-type stars and associates the complex with the rim of a molecular superbubble of diameter ~50 pc and expansion age ~0.3 Myr without establishing causality.
PowerSpectR is an R package implementing median radial power spectrum estimation from imaging data to provide robust summaries of morphological complexity.
