Featured Publications

Galaxies: Abundances

Chemical abundances and deviations from the solar S/O ratio in the gas-phase interstellar medium of galaxies based on infrared emission lines

Unveiling chemical enrichment through IR emission lines; the importance of estimation N and S abundances.

Astrophysics - Astrophysics of Galaxies

A departure from the mass-metallicity relation in merging galaxies due to an infall of metal-poor gas

Mergen-driven infall of metal-poor gas causes metallicity dillutation but enhances star formation, explaining observed properties of (U)LIRGs.
