We present interferometric radio observations of the neutral atomic gas inAGC 727130, a low-mass, gas-rich, field galaxy lacking significantstar-formation. The atomic gas in AGC 727130 displays a pronounced asymmetry,extending well beyond the stellar disk in one direction while remainingrelatively undisturbed in the other. Despite proximity to a pair of interactingdwarfs, tidal analysis suggests these neighboring galaxies are not responsiblefor this pronounced asymmetry. Instead, using a topological cosmic web filamentfinder on spectroscopic catalogue data, we find AGC 727130 lies at theintersection of several large-scale cosmic web filaments, environmentspredicted to host diffuse, shock-heated gas. We propose that an interactionwith this ambient medium is stripping gas from the galaxy via cosmic webram-pressure stripping. This mechanism, supported by recent simulations, mayquench low-mass galaxies outside of massive halos, and must be accounted forwhen comparing observed numbers of dwarf galaxies to theoretical predictions.

Spatially resolved stellar populations of massive, quiescent galaxies atcosmic noon provide powerful insights into star-formation quenching and stellarmass assembly mechanisms. Previous photometric work has revealed that the coresof these galaxies are redder than their outskirts. However, spectroscopy isneeded to break the age-metallicity degeneracy and uncover the driver of thesecolour gradients. Here, we derive age and elemental abundance gradients for 8distant ($1.2 \lesssim z \lesssim 2.2$), massive ($10.3\lesssim\log({\rmM}_*/{\rm M}_\odot)\lesssim 11.1$), quiescent galaxies, by fittingfull-spectrum models to ultra-deep NIRSpec-MSA spectroscopy from theJWST-SUSPENSE survey. We find that these galaxies have negative age, positive[Mg/H] and [Mg/Fe], and flat [Fe/H] gradients, implying that galaxy cores areolder and Mg-deficient compared to galaxy outskirts. The age gradients indicateinside-out quenching, while the Mg-deficient cores suggest rapid gas expulsionas the central quenching mechanism. Thus, galaxy cores formed faster andquenched more efficiently than their outskirts. In this scenario, however, our[Fe/H] and [Mg/Fe] gradients are still puzzling. Our results contrastlower-redshift studies, which find flat age and [Mg/Fe] gradients and negativemetallicity gradients. Additionally, we find a positive trend between agegradients and rotational support, and marginal trends between gradients andgalaxy velocity dispersions and ages. We discuss our findings in the context ofgalaxy growth scenarios, including minor mergers and progenitor bias, and thepossible occurrence of different quenching mechanisms across redshift. Withthis work, we present the first stellar population gradients from NIRSpec-MSAspectroscopy, in the largest current sample of distant, quiescent galaxies.
