We present a sample of low-resolution 5-38 ЮМm Spitzer IRS spectra of the inner few square kiloparsecs of 59 nearby galaxies spanning a large range of star formation properties. A robust method for decomposing mid-infrared galaxy spectra is described and used to explore the behavior of PAH emission and the prevalence of silicate dust extinction. Evidence for silicate extinction is found in ~1/8 of the sample, at strengths that indicate that most normal galaxies undergo AV . ...

... By taking advantage of atomic hydrogen (HI) observations obtained as part of the GALEX Arecibo SDSS and ALFALFA surveys, I will demonstrate that the combination of deep, targeted observations and spectral stacking of blind, large-area shallow surveys is critical in order to characterize how the gas content of galaxies depends on their structure, star formation activity and environment. ...

... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4­5 Gyr than in the sparse ones. ...
