abstract

Disturbed spiral galaxies with high rates of star formation pervaded clusters of galaxies just a few billion years ago, but nearby clusters exclude spirals in favor of ellipticals. ``Galaxy harassment" (frequent high speed galaxy encounters) drives the morphological transformation of galaxies in clusters, provides fuel for quasars in subluminous hosts and leaves detectable debris arcs. Simulated images of harassed galaxies are strikingly similar to the distorted spirals in clusters at $z \sim 0.4$ observed by the Hubble Space Telescope.

  1. Anisotropic quenching beyond $z=1$ and its implications for preprocessing around high-redshift galaxy clusters

    astro-ph.GA 2026-06 unverdicted novelty 7.0 of 10

    Anisotropic quenching is detected at the highest redshift yet and linked to preprocessing dominating over intrahalo effects by ~20% along the major axis in a delay-then-rapid quenching model informed by cluster accret...

  2. Identifying backsplash galaxies using machine learning

    astro-ph.GA 2026-07 conditional novelty 6.0 of 10

    Machine learning trained on The Three Hundred simulations identifies backsplash galaxies in cluster outskirts with ~75% purity/completeness, and has been applied to HI-tail galaxies in Virgo.

  3. Too many quiescent late-type galaxies or a matter of misclassification?

    astro-ph.GA 2026-07 accept novelty 6.0 of 10

    Quiescent late-type galaxies in SDSS morphological catalogues are overestimated by a factor of ~2 due to misclassified edge-on S0 galaxies.

  4. Fuelling the central region of galaxies with misaligned gas accretion

    astro-ph.GA 2026-07 conditional novelty 6.0 of 10

    Kinematically misaligned gas accretion sustains main-sequence-level star formation only below ~1e10 Msun; above that, central gas is present but dilution by pre-existing mass keeps specific star formation low.

  5. From DES to KiDS: Domain adaptation for cross-survey detection of low-surface-brightness galaxies

    astro-ph.GA 2026-05 unverdicted novelty 6.0 of 10

    Domain adaptation with an ensemble of CNN and transformer models trained on DES detects 20,180 LSBGs and 434 UDGs in KiDS DR5, with structural parameters and environmental trends consistent with known samples.

  6. No hidden monsters: Probing recently-quenched galaxies for obscured AGN with JWST-PRIMER MIRI and NIRCam

    astro-ph.GA 2026-06 unverdicted novelty 5.5 of 10

    Massive post-starburst galaxies at 1<z<2 show no mid-IR excess, limiting any dust-obscured AGN to Eddington ratios below 1%, while low-mass PSBs retain residual star formation.

  7. A SHARP Look at Quenching and Bulge-Disk Growth in Massive Galaxies at Cosmic Noon

    astro-ph.GA 2026-06 unverdicted novelty 5.0 of 10

    Observing proposal for high-resolution near-IR IFS to enable bulge-disk decomposition of stellar populations and gas mapping in massive galaxies at cosmic noon to study quenching.

  8. On the later evolution of observationally selected protocluster candidates at $z\,{\gtrsim}\,5$

    astro-ph.GA 2026-06 unverdicted novelty 5.0 of 10

    Simulations show observationally selected protocluster candidates at z ≳ 5 include significant interlopers, undergo 2-6 major mergers, and exhibit stronger clustering than observed, requiring total galaxy mass within ...

  9. Satellite compaction pathways: environmental drivers shaping dwarf galaxy corpulence in the TNG50 simulation

    astro-ph.GA 2026-06 unverdicted novelty 5.0 of 10

    In TNG50, compact dwarf satellites (log M_star 8.4-9.2) form via DM-rich gas inflows in low-merger environments, tidal stripping for DM-poor cases, and ram-pressure starbursts for some metal-rich ones.

  10. Cosmic web stripping and starvation of low-mass filament galaxies in TNG50

    astro-ph.GA 2026-05 unverdicted novelty 5.0 of 10

    Low-mass filament galaxies in TNG50 exhibit smaller asymmetric cold gas discs due to cosmic web tidal fields causing altered accretion or starvation and late-time stripping, while integrated stellar and halo propertie...
