An analysis of the IRAS data for a sample of classical (optically selected) Seyfert galaxies is presented. The IRAS fluxes at 25 micron, 60 micron, and 100...

The present volume on stellar formation discusses basic physical principles relevant to such processes, regions of recent star formation, galaxy formation and...

We estimate the current extinction-corrected Hα star formation rate (SFR) of the different morphological components that shape galaxies (bulges, bars, and disks...

Several positions in the southern spiral arm and the interarm disk of NGC 4321 have been observed in CO (J = 1 to 0) using the NRO 45 m telescope at Nobeyama...

We present the first results of a narrow-band photometric study of the massive galaxy cluster XMMU J2235.3-2557 at z= 1.39. We obtained deep H narrow-band...

We investigate the relation between star formation rates (dot{{M}}_s) and AGN properties in optically selected type 1 quasars at 2 z 3 using data from...

Using broad band photometry, a new method is derived to evaluate relative (arm with respect to the interarm disk) star formation rates and relative star...

Numerical simulations predict that metal-poor gas accretion from the cosmic web fuels the formation of disk galaxies. This paper discusses how cosmic gas...

Context. The physical processes driving the evolution of star formation (SF) in galaxies over cosmic time still present many open questions. Recent galaxy...
