Using integrated optical spectrophotometry for 412 star-forming galaxies at z~ 0, and fiber-
aperture spectrophotometry for 120,846 SDSS galaxies at z~ 0.1, we investigate the Hα …

We study the dependence of star formation quenching on galaxy mass and environment, in
the Sloan Digital Sky Survey (SDSS; z∼ 0.1) and the All-Wavelength Extended Groth Strip …

This paper considers the techniques to distinguish normal star-forming (NSF) galaxies and
active galactic nuclei (AGNs) hosts using optical spectra. The observational data base is a …

We present the observed fraction of galaxies with an active galactic nucleus (AGN) as a
function of environment in the early data release of the Sloan Digital Sky Survey (SDSS) …

We study galaxy pairs (GPs) in the field selected from the 100-K public release of the Two
Degree Field (2dF) galaxy redshift survey. Our analysis provides a well-defined sample of …

We derive the first luminosity-metallicity (LZ) relation for a large objectively selected sample
of local galaxy pairs, and we compare the LZ relation of the pairs with the relation for the …

Abstract The CAIRNS (Cluster and Infall Region Nearby Survey) project is a spectroscopic
survey of the infall regions surrounding eight nearby, rich, X-ray–luminous clusters of …

We use integral-field spectroscopy from the SAMI Galaxy Survey to identify galaxies that
show evidence of recent quenching of star formation. The galaxies exhibit strong Balmer …

We discuss the selection and observations of a large sample of nearby galaxies, which we
are using to quantify the star formation activity in the local Universe. The sample consists of …

We present a study of the prevalence of optical and radio nuclear activity with respect to the
environment and interactions in a sample of the Sloan Digital Sky Survey (SDSS) galaxies …
