Detection of helium lines in Balmer-dominated shocks of Type Ia SNRs reveals enhanced helium in some remnants and challenges shock models, enabling new constraints on progenitor environments.
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.
Spectroscopic data indicate that the ionized gas in ORC4's central galaxy is shock-ionized by a wind associated with the radio ring's formation.
A new sample of 157 mid-IR dual AGN candidates in mergers yields 13 confirmed cases and 63 strong candidates at separations 14.5-129 kpc, over half beyond 50 kpc, with diverse BPT classes and 31% in multi-mergers.
New NIR diagnostic diagrams using [C I]/Paγ and H2 1-0 O(5)/PAH 3.3μm ratios correlate with radiation field hardness and distinguish star formation, AGN, and shock excitation in galaxy nuclei.
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.
UV background suppresses NEI in galaxy haloes, restoring equilibrium shock thresholds and producing extended absorption columns for OVI, CIV, and HI beyond the virial radius.
MAUVE-MUSE finds Virgo cluster disks have elevated [N II]/Hα, [S II]/Hα and [O III]/Hβ ratios plus broader kinematics because star formation is suppressed, leaving diffuse ionized gas dominant instead of widespread direct environmental excitation.
42 supernova remnants confirmed in NGC3344 via [S II]/Hα selection, Sabbadin plots, BPT diagrams and shock models from SITELLE data.
