Michele Trenti's Research I: Galaxy Formation, Evolution and Dynamics
My latest interest is on Population III stars and minihalos
during the dark ages. I will post my results soon.
Work in progress also include:
The Environments of High Redshift QSOs , Kim, Stiavelli, Trenti, and 9 coauthors, ApJ submitted
The UDF05 Follow-up of the HUDF: II. Constraints on Reionization from z-dropout Galaxies , Oesch, Carollo, Stiavelli, Trenti, and 10 coauthors, ApJ accepted
I am also working on the Dynamical evolution of galaxy
bulges: harassment, tidal streams and interactions with globular
clusters, a project with Massimo Stiavelli, Rosie Wyse and Marcella
Carollo as CoIs. This fits nicely with my interest in globular clusters . Paper is almost ready to submit.
Recently completed projects range from PopIII stars to Damped Lyman Alpha Systems. My first observational paper (on V-dropouts in the UDF follow-up fields) has been published last year and I have now been awarded HST time as PI ( GO11700, 142 orbits ). Little more than two years at STScI and I have been able to transition from theorist to PI of one of the 10 largest observational programs approved in Cycle 17.

My Ph.D. Thesis was centered on a theoretical and numerical
investigation of the properties of collisionless stellar systems. My
results on this are in:
