An Extremely Red r^{1/4} Galaxy in the Test Image of the Hubble Deep Field South
T. Treu, M. Stiavelli, A. R. Walker +14
We report the serendipitous discovery of an extremely red object in the Hubble Deep Field South (HDFS) Test NICMOS (Near Infrared Camera and Multi Object Spectrograph) field of vie…
Spiral galaxies with WFPC2: III. Nuclear Cusp Slopes
C. M. Carollo, M. Stiavelli
In this paper, the third of a series dedicated to the investigation of the nuclear properties of spiral galaxies, we have (i) modelled the WFPC2 F606W nuclear surface brightness pr…
Spiral galaxies with WFPC2: II. The Nuclear Properties of 40 objects
C. M. Carollo, M. Stiavelli, J. Mack
We report the analysis of HST WFPC2 F606W images of 40 spirals belonging to the sample introduced in Carollo et al. (paper I), where 35 other targets were discussed. We describe th…
Effective Star Formation Rates for Cosmological Applications
Marco Spaans, Marcella Carollo
Effective star formation rates in tabular form are computed which yield a prescription for the star formation activity in model galaxies as a function of ambient density, metallici…
