The Star Formation History of the Virgo early-type galaxy NGC4435: the Spitzer Mid Infrared view
P. Panuzzo, O. Vega, A. Bressan +7
We present a population synthesis study of NGC4435, an early-type Virgo galaxy interacting with NGC4438. We combine new spectroscopic observations obtained with the Spitzer Space T…
Small Scale Systems of Galaxies. III. X-ray detected E+S galaxy pairs in low density environments
R. Gruetzbauch, G. Trinchieri, R. Rampazzo +4
We present a comprehensive study of the local environments of four E+S galaxy pairs with the main goal to investigate their formation/evolution histories. New XMM-Newton data were…
Nearby early-type galaxies with ionized gas. III. Analysis of line-strength indices with new stellar population models
F. Annibali, A. Bressan, R. Rampazzo +2
In this paper we study the underlying stellar population of a sample of 65 nearby early-type galaxies predominantly located in low density environments. Ages, metallicities and [al…
Ongoing Star Formation in the BL Lacertae object PKS 2005-489
A. Bressan, R. Falomo, J. R. Valdes +1
We present VLT long slit optical spectroscopy of the luminous BL Lacertae object PKS 2005-489. The high signal-to-noise ratio and the good spatial resolution of the data allow us t…
The SPITZER IRS view of stellar populations in Virgo early type galaxies
A. Bressan, P. Panuzzo, L. Buson +7
We have obtained high S/N Spitzer IRS spectra of 17 Virgo early-type galaxies that lie on the colour-magnitude relation of passively evolving galaxies in the cluster. To flux calib…
The star formation history of early-type galaxies as a function of mass and environment
M. S. Clemens, A. Bressan, B. Nikolic +3
Using the third data release of the Sloan Digital Sky Survey (SDSS) we have rigorously defined a volume limited sample of early-type galaxies in the redshift range z < 0.1. We have…
