abstract
We investigate the accuracy of the parametric recovery of the line-of-sight velocity distribution (LOSVD) of the stars in a galaxy, while working in pixel space. Problems appear when the data have a low signal-to-noise ratio, or the observed LOSVD is not well sampled by the data. We propose a simple solution based on maximum penalized likelihood and we apply it to the common situation in which the LOSVD is described by a Gauss-Hermite series. We compare different techniques by extracting the stellar kinematics from observations of the barred lenticular galaxy NGC 3384 obtained with the SAURON integral-field spectrograph.

Spatially resolved spectroscopy shows SDSS1335+0728 has a three-zone ionisation structure, optically thin dust, and sustained low-level nuclear activity for at least 1500 years, implying the Ansky event is a faint transient in an already accreting low-mass SMBH.
First narrow-line flux ratios for lensed quasar RXJ1131-1231 measured with JWST/NIRSpec IFS at ~5% precision, detecting cusp anomaly consistent with prior work.
Simultaneous measurement of low- and high-mass IMF slopes in 214 star-forming galaxies reveals diversity, weak correlation between ends, and links to stellar mass, star formation rate, and metallicity.
Resolved multiphase observations reveal a supernova-driven wind in a z=5.3 galaxy removing gas at twice the star-formation rate, potentially quenching it within 100 Myr and matching local superwind properties.
A JWST census detects neutral ISM absorption in 76 of 309 galaxies at 0.6<z<4 and outflows in 26, indicating AGN-driven neutral outflows dominate in quiescent systems at cosmic noon.
AGN activity in Mrk 573 enriches the surrounding gas with metals up to several times solar abundance on 100-parsec scales via outflows and jets.
AGN radiation pressure, not black-hole mass, simultaneously boosts large-scale [O III] outflows and clears circumnuclear gas as Eddington ratio rises.
Post-starburst galaxies show compact morphologies with minimal wavelength-dependent structural change and low overall disturbance levels, except for enhanced residual asymmetry in massive systems at z > 1, supporting two distinct quenching pathways.
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.
A JWST survey of eight gravitationally lensed galaxies at z=2-4 resolves 10-200 pc star-forming clumps and finds early evidence of recently quenched, post-starburst clumps.
High [Si/Mg] = 0.67 in NGC 1277 cannot be explained by standard models and suggests pair-instability supernovae from very massive early stars.
At fixed stellar mass, inner gas mass—not size, SFR, or potential—best predicts gas metallicity, and differences in long-term inflow histories can explain the pattern.
A PN in a 90 Myr M31 cluster is associated via position and velocity, implying a 5.66 solar mass progenitor with nitrogen enhancement.
Spatially resolved observations of z~0.1 galaxies show Mg II absorption outflow velocities are systematically higher than Hα emission velocities by ~0.4 dex while maintaining similar correlations with star formation rate and surface density.
JWST observations of ERQs show stratified gas kinematics via deblended optical emission lines, with UV lines dominated by scattered light and optical lines mixing scattered and obscured emission.
A hybrid CNN-Transformer denoiser trained on synthetic spectra substantially reduces noise and improves stellar population recovery for low-S/N galaxy observations in controlled tests.
Milky Way abundance trends act as effective empirical proxies for nucleosynthetic yields, recovering alpha and Fe-peak abundances in quiescent galaxies with 0.05 dex median offset versus 0.23 dex for theory, indicating largely universal yields.
DESI DR2 identifies 50,088 galaxies with moderate and 27,420 with strong evidence for down-the-barrel NaI D absorption revealing inflows at ~20 km/s and multiple accretion pathways at z < 0.6.
Multi-phase observations of NGC 1427A indicate tidal torquing from a dwarf fly-by has pre-conditioned its gas for ram-pressure stripping by the Fornax intracluster medium, placing the galaxy at the onset of environmental quenching with a declining star formation rate.
Multiphase observations show molecular gas mass loading factors 10 times higher than ionised gas in ESO 484-036, creating a 3.5 dex discrepancy with cosmological simulations that underpredict cold gas outflows.
Spatially-resolved spectroscopy detects AGNs in 4-9% of low-mass galaxies, higher than single-fiber rates because it catches extended emission missed by central-point observations.
Improved pPXF uses analytic Fourier transforms of Gauss-Hermite functions for accurate convolution, providing reliable velocities even when σ is much less than the sampling ΔV.
Composite time-delay lens modelling of JWST WFI2033–4723 yields intermediate stellar IMF normalisation and a steep gNFW inner slope γ_in≃1.3 that is robust to the choice of external cosmology.
