On the interpretation of age and chemical composition of composite stellar populations determined with line-strength indices
Paolo Serra, Scott C. Trager
We study the simple-stellar-population-equivalent (SSP-equivalent) age and chemical composition measured from the Lick/IDS line-strength indices of composite stellar populations (C…
The impact of neutrino masses on the determination of dark energy properties
Axel De La Macorra, Alessandro Melchiorri, Paolo Serra +1
Recently, the Heidelberg-Moscow double beta decay experiment has claimed a detection for a neutrino mass with high significance. Here we consider the impact of this measurement on…
Cosmological bounds on dark matter-neutrino interactions
Gianpiero Mangano, Alessandro Melchiorri, Paolo Serra +2
We investigate the cosmological effects of a neutrino interaction with cold dark matter. We postulate a neutrino that interacts with a ``neutrino interacting dark matter'' (NIDM) p…
IC 4200: a gas-rich early-type galaxy formed via a major merger
P. Serra, S. C. Trager, J. M. van der Hulst +2
We present the result of radio and optical observations of the S0 galaxy IC 4200. We find that the galaxy hosts 8.5 billion solar masses of HI rotating on a ~90 deg warped disk ext…
