An analysis of IRAS data for a sample of classical (optically selected) Seyfert galaxies is presented. The IRAS fluxes at 25, 60, and 100 μm are found to be...

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...

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 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...

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...

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...

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