The ring images presented here are part of a larger William Herschel Telescope (WHT) imaging survey (1999 and 2000) conducted to characterize the nuclear and...
Star formation in outer rings of S0 galaxies. V. UGC 4599: An S0 with gas probably accreted from a filament
Aims: Though S0 galaxies are usually thought to be `red and dead', they often demonstrate weak star formation organised in ring structures and located in their...
We present narrowband observations of the Hα emission in a sample of 31 satellites orbiting isolated giant spiral galaxies. The sample studied spans the range...
Star formation in the Large Magellanic Cloud. III. A study of the regions LMC-30, LMC-45 and LMC-61.
In this paper we present the BV-CCD photometry of three stellar fields of the Large Magellanic Cloud (LMC). They are taken at the center of V-charts of the...
Star Formation in the Local Universe from the CALIFA Sample. II. Activation and Quenching Mechanisms in Bulges, Bars, and Disks
We estimate the current extinction-corrected Hα star formation rate (SFR) of the different morphological components that shape galaxies (bulges, bars, and disks...
Star Formation in the Spiral Arms of NGC 4321. II. H i Distribution and Kinematics
We present H I 21 cm observations of the grand design spiral galaxy NGC 4321, as obtained with the VLA. From our original data, we have obtained data cubes with...
Star formation in the XMMU J2235.3-2557 galaxy cluster at z= 1.39
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...
Star formation rates in luminous quasars at 2 < z < 3
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...
Star formation rates of distant luminous infrared galaxies derived from Hα and IR luminosities
We present a study of the star formation rate (SFR) for a sample of 16 distant galaxies detected by ISOCAM at 15 μm in the CFRS0300+00 and CFRS1400+52 fields...
