Massive quiescent compact galaxies have been discovered at high redshifts, associated with rapid compaction and cessation of star formation (SF). In this work...

PublicationConstraining the top-light initial mass function in the extended ultraviolet disk of M 83
Context. The universality or non-universality of the initial mass function (IMF) has significant implications for determining star formation rates and star...

PublicationDeep submillimetre and radio observations in the SSA22 field. II. Submillimetre source catalogue and number counts
We present the deepest 850 $\mu$m map of the SSA22 field to date, utilizing a combination of new and archival observations taken with SCUBA-2, mounted at the...

PublicationDensity wave triggered star formation in grand design spirals
In normal spiral galaxies the arms are the main sites for star formation. This is the cause of their optical contrast compared with the rest of the disc. The...

PublicationDensity waves and star formation in grand-design spirals
Context. H II regions in the arms of spiral galaxies are indicators of recent star-forming processes. They may have been caused by the passage of the density...

PublicationDetection of the self-regulation of star formation in galaxy discs
Stellar feedback has a notable influence on the formation and evolution of galaxies. However, direct observational evidence is scarce. We have performed stellar...

PublicationDetection of young (≤20 Myr) stellar populations in apparently quenched low-mass galaxies using red spectral line indices
We report on the detection of a small contribution (around and below 1 per cent in mass) from young stellar components with ages ≤20 Myr in low-mass galaxies...

PublicationDiagnostic diagrams of H 0 regions in the Local Group
We have studied here for the first time the use of the log(H 0/[N 0]), log (H 0/[S 0]) diagnostic diagram for determining the metallicities and ionization...

PublicationDiagnostics of the underlying physical differences between flocculent and well-defined spiral galaxies
From published catalogs, basic physical properties including diameters, masses, and neutral hydrogen contents of spiral galaxies have been studied as a function...
